Rapidly warming climate, tightening environmental requirements, an aging society, rising wages, and demand for organic products are forcing farming to be more efficient and sustainable. The main aim of this study was to perform an analytical analysis and to determine the energy use and GHG emissions of organic sugar beet production using different weed control methods. Seven different methods of non-chemical weed control were compared. Mechanical inter-row loosening, inter-row cutting and mulching with weeds, weed smothering with catch crops, and thermal inter-row steaming were performed in field experiments at the Experimental Station of Vytautas Magnus University (Lithuania, 2015–2017). The other three, namely, automated mechanical inter-row loosening with cameras for row-tracking, inter-row loosening with a diesel-powered robot, and inter-row loosening with an electric robot were calculated analytically. The results showed that the average total energy use of organic sugar beet production was 27,844 MJ ha−1, of which manure costs accounted for 48–53% and diesel fuel for 29–35%. An average energy efficiency ratio was 7.18, while energy productivity was 1.83 kg MJ ha−1. Analysis of GHG emissions showed that the total average GHG emissions to the environment from organic sugar beet production amounted to 4552 kg CO2eq ha−1, and the average GHG emissions ratio was 4.47. The most sustainable organic sugar beet production was achieved by using mechanical inter-row loosening with a diesel-powered robot for weed control.

Analyses of statistical data were made and their results discussed in this article to identify the level of Poland’s energy security and to determine the role of agriculture in ensuring it. It has been demonstrated that coal continues to be the staple resource for the generation of energy in Poland. The current demands and requirements concerning the reduced consumption of non-renewable resources and Poland’s obligations towards the European Union regarding the production of energy from renewable resources—all these considerations contribute to the promotion of a skillful development of energy crop farming, which, in Poland, is likely to be very successful. Agriculture plays an important role in ensuring Poland’s energy security, and this branch of farming can grow dynamically provided adequate legal regulations and promotion are in place. The chief resource for renewable energy generation is biomass. Straw and biogas production in agricultural biogas plants are two solutions whose full energy production potential still awaits to be tapped.

Differently tilled faba bean cultivations, in particular, require a comprehensive study of weed diversity, abundance, and seedbank due to the lack of experimental data. Therefore, in 2016–2018, field trials were conducted at Vytautas Magnus University on the basis of a long-term tillage experiment. Conventional deep and shallow plowing, deep chiseling, shallow disking, and no-tillage systems were investigated. According to the results of the investigations, the air temperature and amount of precipitation during the vegetative season had a greater influence on the total number of weeds (r = 0.538 and 0.833 p > 0.05) than the types of tillage systems investigated. However, on average, a reduction in tillage intensity did not change the weed number, especially in disked and not tilled plots. On average, the biomass of weeds varied little between the treatments (from 105.9 to 125.7 g m−2) and mainly depended on the volume of forecrop residues (rannual = −0.982 p ≤ 0.01 and rperennial = 0.890 p ≤ 0.05). Higher total weed seedbanks were found in the disked (+43.0%) and not tilled (+21.6%) soils compared to deeply plowed ones. The weed seedbank was almost similarly distributed between the treatments, irrespective of the tillage depth and method used.

Conservation agriculture has three main pillars, i.e., minimum tillage, permanent soil cover, and crop rotation. Covering the soil surface with plant residues and minimum mechanical soil disturbance can all result from introducing a strip-till one-pass (ST-OP) system. The aim of this study was to determine the impact of the ST-OP technology on the management of plant residues, soil properties, inputs, and emissions related to crop cultivation. We compared the effect of a ST-OP system against conventional tillage (CT) using a plough, and against reduced, non-ploughing tillage (RT). Four field experiments were conducted for evaluating the covering of soil with plant residues of the previous crop, soil loss on a slope exposed to surface soil runoff, soil structure and aggregate stability, occurrence of soil organisms and glomalin content, soil moisture and soil water reserve during plant sowing, labour and fuel inputs, and CO2 emissions. After sowing plants using ST-OP, 62.7–82.0% of plant residues remained on the soil surface, depending on the previous crop and row spacing. As compared with CT, the ST-OP system increased the stability of soil aggregates of 0.25–2.0 mm diameter by 12.7%, glomalin content by 0.08 g·kg−1, weight of earthworms five-fold, bacteria and fungi counts, and moisture content in the soil; meanwhile, it decreased soil loss by 2.57–6.36 t·ha−1 year−1, labour input by 114–152 min·ha−1, fuel consumption by 35.9–45.8 l·ha−1, and CO2 emissions by 98.7–125.9 kg·ha−1. Significant favourable changes, as compared with reduced tillage (RT), were also found with respect to the stability index of aggregates of 2.0–10.0 mm diameter, the number and weight of earthworms, as well as bacteria and fungi counts.

Soil tillage intensity influences the chemical composition of soil, the distribution of nutrients, and soil physical and mechanical properties, as well as gas flows. The impact of reduced tillage on these indices in faba bean cultivation is still insufficient and requires more analysis on a global scale. This study was carried out at Vytautas Magnus University, Agriculture Academy (Lithuania) in 2016–2018. The aim of the investigation was to establish the influence of the tillage systems on the soil chemical composition, temperature, moisture content, and CO2 respiration in faba bean cultivation limited by the semi-humid subarctic climate. On the basis of a long-term tillage experiment, five tillage systems were tested: deep and shallow moldboard plowing, deep cultivation-chiseling, shallow cultivation-disking, and no-tillage. Results showed that in conditions of plowless tillage systems, the content of precrops’ residues on the topsoil before the spring tillage was 5 to 15 times higher than in plowed plots. It undoubtedly was for the amount of available nutrients in the soil, soil temperature, and moisture content. Plowless and no-tillage systems could initiate an increase in the amount of available nutrients in soil. The highest concentration of chemical elements was found in no-tilled plots. So faba bean crops could largely increase the composition of potassium and total nitrogen and stabilized CO2 respiration from soil during one vegetative period.

Tillage is an agrotechnical practice that strongly affects the soil environment. Its effect on soil properties depends on the system and, more specifically, on the degree of soil inversion and loosening. Strip-till is a non-inversive method that loosens only narrow soil strips. In strip-till one-pass (ST-OP) technology, tillage is combined with a simultaneous application of fertilizers and seed sowing. In a static multi-year field experiment, the soil properties after application of ST-OP for 8 years were compared to those of soil under conventional tillage with the use of a moldboard plough to a depth of 20 cm (CT), and equally deep loosened and mixed reduced tillage (RT). A field experiment of these three treatments was performed since 2012 in sandy loam soil, Luvisol. A total of 44 features were examined that described the physical, chemical, biological, and biochemical soil properties in the 0–20 cm layer, and penetration resistance (PR), bulk density (BD), and soil moisture (SM) in the 25–30 cm layer. The influence of the ST-OP technology on the yield of crops was also determined. Multivariate analysis shows that the ST-OP method, in terms of affecting the soil properties, differs considerably from RT and CT treatments. The soil after the ST-OP method contained two- to four-fold more earthworms (En), with a mass (Em) 2- to 5-fold higher, than those in the soil following RT and CT, respectively. In the ST-OP soil the content of available phosphorus (Pa) and available potassium (Ka); the total count of bacteria (Bt), cellulolytic microorganisms (Bc), and fungi (Ff); and the activity of phosphatases (AlP, AcP) were significantly higher. Compared with CT, the content of total organic carbon (Ct) and its content in the fractions of organic matter were also higher, with the exception of humins (CH). The yields of winter rapeseed and winter wheat using the ST-OP technology were marginally higher compared with those using the CT and RT technology.

There is a lack of research on the practice of intercropping sugar beet and the impact of such agrocenoses on soil and crop fertility, especially under organic farming conditions. For this reason, a three-year stationary field experiment was performed at Vytautas Magnus University, Agriculture Academy, Lithuania. Sugar beet was grown continuously with intercropped Persian clover (Trifolium resupinatum L., MC), white mustard (Sinapis alba L., MM) and spring barley (Hordeum vulgare L., MB) as a living mulch. Inter-row loosening (CT) and mulching with ambient weeds (MW) were used as comparative treatments. The results showed that, under minimal fertilization, CT and intercropping increased the average content of nitrogen, phosphorus and potassium in the soil. However, the average content of magnesium was reduced in single cases (MW, MB), and the average content of sulphur was reduced in all cases. Intercropping significantly decreased the yields of sugar beet root-crop, but was mainly neutral in quality terms. The meteorological conditions during experimentation had a weak impact on root-crop quantity and quality. Generally, the practice of sugar beet intercropping requires more detailed research on how to minimize the competition between the sugar beet, living mulch and weeds, and how to balance the nutrition conditions.

This article analyses and evaluates the impact of the technology of soil processing on the biomass indicators of faba bean waste. Samples from five different primary tillage systems were taken and analysed. The raw material of faba bean waste was processed and pressed into cylindrical pellets. The results of the experimental research of the pellet properties revealed that the content of moisture of the pellets from faba bean waste changed from 8.2% (deep cultivation, 3-GP) to 10.8% (untreated soil, 5-ND). The highest density of faba bean waste pellets was obtained from the sample of conventional soil ploughing, (1-IA) (1311 kg m−3), while the lowest density was recorded under shallow ploughing (2-SA) – 1275 kg m−3. The lower calorific value of dry biofuel from faba bean waste pellets was similar in all the samples and ranged from 16.9 MJ kg−1 (5-ND) to 17.1 MJ kg−1 (2-SP). The calorific value of faba bean waste pellets was relatively high and was close to the calorific value of some types of wood waste. The following harmful gas emissions were analysed and evaluated: carbon monoxide CO, carbon dioxide CO2, unburned hydrocarbons CxHy, and nitrogen oxides NOx. The harmful gas environmental emissions detected while burning the pellets of faba bean waste have not exceeded the permissible limits. The best results of the pellet properties, the content of ash and the emissions were obtained under conventional ploughing (1-IA) and deep cultivation (3-GP). The research results suggest that faba bean waste could be used as granulated biofuel, since the main parameters of this legume waste correspond to the basic requirements of solid biofuel. It was determined that under untreated soil (5-ND) technology the CO2 emissions eqv. were twice lower than under conventional soil ploughing (1-IA). These results show that no-till technology is suitable for sustainable agricultural practise both for producing the faba bean grain and for processing the pellets from the waste.

Faba beans are an important crops in the agricultural crop rotations and are valuable as medicine, food and feed. Faba beans improve the soil, reduces the utilization of chemical fertilizers for future crops and contribute to the reduction of environmental pollution in agriculture. The aim of this work was to evaluate the potential for environmental mitigation, including the reduction of total greenhouse gas (GHG) emissions from agricultural inputs, and the potential for improving the energy efficiency in faba bean production by managing tillage intensity. Experiments in faba bean production were performed using five tillage methods with different intensities: T-1-C, conventional tillage with deep ploughing at a depth of 23–25 cm (as a control); T-2, shallow ploughing at a depth of 12–15 cm; T-3, deep chiselling at a depth of 23–25 cm; T-4 – shallow cultivation at a depth of 12–15 cm; and NT, no-tillage. The results showed that the replacement of deep ploughing with lower-intensity tillage operations in faba bean production reduced fuel consumption by 9.8–50.8%, total energy consumption by 298–1194 MJ ha−1 and total GHG emissions by 21–128 kg CO2eq ha−1. The highest yields of beans (4.41 Mg ha−1) and energy output (88,133 MJ ha−1) were obtained under treatment T-3, whereas the best energy productivity (0.37 kg MJ−1) and energy efficiency ratio (7.43), and the lowest environmental pollution (481 CO2eq ha−1) were observed under the NT treatment. The analyse of energy efficiency and pollution in this research led to very important findings: less intensive and more soil-friendly tillage practices have a considerable potential for environmental mitigation in agriculture and simultaneously improve energy efficiency without reducing yield.

Research related to fertilization in winter triticale cultivation was limited to macroelements. The effects of boron on triticale (deficiency or toxicity) affecting productivity are still unknown. In 2013–2015, a field experiment was carried out at the Experimental Station in Tomaszkowo near Olsztyn. The objective was set response of winter triticale variety Pigmej under the influence of various levels of nitrogen (N) and boron (B) fertilization. Five levels of nitrogen fertilization: 0, 40, 80 (50 + 30), 120 (90 + 30), and 160 (90 + 70) kg ha−1 and four levels of boron fertilization: 0, 0.8, 1.6, and 2.4 kg ha−1 were tested. The experiment has demonstrated considerable differences in the grain yield volume and structure under the influence of various weather conditions and different doses of nitrogen. The difference between the highest and lowest grain yield was 1.7 t ha−1—53.6%. The effect of boron application was also manifested as an increase in the winter triticale grain yield and improved yield component structure, but the statistically significant differences were observed only in ears number per 1 m2. The highest dose of boron applied in the experiment caused a decrease in the quantity of grain yield and its component parts.

Energy use in agricultural production has been increasing faster than in many other sectors of the world economy. Owing to high energy consumption during the production of agricultural inputs, with mineral nitrogen fertilizers in particular, it is often questioned as to whether agricultural production is still energy efficient. The objective of this research was to evaluate the energy efficiency of different intensity systems for the production of semi-dwarf winter triticale cultivar ”Twingo”. Cultivar “Twingo” entered the Polish National List in 2012 as one of the best yielding. For this reason, it was used in this experiment to examine its response to basic agrotechnical factors. The field experiment was conducted in the Agricultural Experiment Station in Tomaszkowo in 2013–2015. Low-input, medium-input and high-input production systems were evaluated. The compared systems differed in nitrogen fertilization rates and the level of fungicide protection. The highest output/input ratio was noticed growing winter triticale in low-input production system. The most energy-consuming operation during winter triticale production in the compared systems was mineral fertilization. The high-input production system was significantly lower energy efficiency than the other systems (6.21, medium-input 5.95, low-input 8.19). The energy return on investment (EROI) ratio was low, but above 1, in all the analyzed technologies (low-input 1.30, medium-input 1.14, high-input 1.15). The energy value of the bioethanol produced was higher than the energy inputs into the production of raw material and its processing. The conversion of winter triticale grain to bioethanol proved that the EROI reached the most favorable value for the low-input production system.

Biomass is playing an increasingly important role as a source of renewable energy. The aim of this study has been to identify the potential applicability of straw from agricultural crops to generate energy within the district of Braniewo, in the province Warmia and Mazury, Poland. The study covered the years 2015 to 2017. Based on statistical data, and using appropriate equations and norms, the structure of crop production and the number of livestock in the mentioned district were analysed; the potential production volume of straw was estimated, from which the amount needed for animal production (feed and bedding) was deducted, while the organic substance balance in soil was calculated. An annual average amount of straw remaining to be used for energy purposes in the district of Braniewo is about 41,531 t of straw, equivalent to about 60,222 GJ of energy (24,088 t of coal). In addition to the above analyses, a survey was conducted among local farmers, which showed their opinions about barriers to and opportunities for growing crops for energy purposes and using renewable energy resources. The survey results justify the claim that there is certain potential among farmers in the district of Braniewo to grow crops for energy purposes.

Different tillage technologies have different effects on CO2 emissions from soil. Unfortunately, little information exists about the impact of different types of tillage as compared with no-tillage, and the main controls. The aim of this research is to determine the relationship between physicomechanical, chemical and biological properties of soil and CO2 emissions from differently tilled soils under the climatic conditions of central Lithuania before and after autumn tillage. The studies were conducted in 2009–2012 and 2014 at the Experimental Station of Aleksandras Stulginskis University in Central Lithuania. Different tillage technologies were applied: deep ploughing at 23–25 cm depth (DP); shallow ploughing at 12–15 cm depth (SP); deep cultivation with a cultivator at 25–27 cm depth (DC); shallow cultivation with a disc harrow at 12–15 cm depth (SC); and no-tillage (NT). The correlation of physicomechanical, chemical and biological soil properties with CO2 emissions was determined. During all the experimental period total CO2 emissions from soil in DP, SP, DC, SC and NT technologies were respectively 6.05, 4.25, 4.97, 4.42, 3.94 μmol m−2 s−1 before autumn soil tillage and 29.88, 22.50, 16.73, 13.72, 10.00 μmol m−2 s−1 after autumn tillage. Negative correlation between soil temperature and CO2 emissions before the autumn tillage from soil was evidenced (r = −0.98). A strong negative correlation between soil respiration and total soil porosity was observed. Correlation between aeration soil porosity and CO2 emissions was strong. After autumn tillage, the strongest correlations were found between soil penetration resistance and respiration in the upper (r = −0.75) and deeper (r = −0.71) layers. In autumn, a significant strong correlation (r = 0.78) between soil respiration and aeration porosity was obtained in the upper soil layer under ploughing or cultivation. This study revealed that CO2 emissions were significantly higher immediately after autumn ploughing technologies compared to deep and shallow cultivation and no-tillage.

The complex mutual interactions between soil properties and plants in high-biodiversity mono-cropping agro ecosystems have not been widely investigated. For this purpose, during 2009-2011, a stationary field experiment was conducted at the Experimental Station of the Aleksandras Stulginskis University to establish the effect of a multi-component agrocenose (maize, living mulch, weeds) on the physical properties of the soil. Spring oilseed rape, white mustard, spring barley, Italian ryegrass, black medic, Persian clover and red clover were sown as living mulch into maize inter-rows. The stability of >1.0 mm aggregates increased between the beginning and end of the maize vegetative period in almost all of the crops containing living mulch. The greatest competition for moisture content between the inter-crops and maize was observed at the beginning of the vegetative period because of living mulches of long growing seasons using the most moisture. In many cases, the shear strength of the soil was significantly reduced by the living mulch in the middle of summer, when it covered the maize inter-rows. These findings show that the monocropping of maize with living mulch stabilises or improves the physical characteristics of the soil, highlighting its potential for sustainable maize growing.

Lauko eksperimentas įrengtas 1988 m. tuometinėje Lietuvos žemės ūkio akademijos Bandymų stotyje. Eksperimentas atliktas 4 pakartojimais. Iš viso buvo 20 laukelių. Eksperimento variantų laukeliai išdėstyti rendomizuotai. Augalų rotacija eksperimente: 1) vasariniai rapsai; 2) žieminiai kviečiai; 3) kukurūzai; 4) vasariniai miežiai. Pagrindinio žemės dirbimo supaprastinimas ir tiesioginė sėja į neįdirbtą dirvą neturėjo esminės įtakos dirvožemio tankiui. Viršutiniame (5– 10 cm) ir viduriniame (15–20 cm) dirvožemio sluoksniuose supaprastinti žemės dirbimai neturėjo esminės įtakos bendrajam poringumui ir porų pasiskirstymui, palyginti su tradiciniu žemės dirbimu. Giliausiame (30– 35 cm) tirtame dirvožemio sluoksnyje visi supaprastinti žemės dirbimai neturėjo esminės įtakos bendrajam poringumui. Didinat siurbimo jėgą didžiausias drėgmės kiekis dirvožemio 5–10 ir 15–20 cm sluoksniuose nustatytas taikant gilųjį purenimą ir tiesioginę sėją į neįdirbtą dirvą, palyginti su tradiciniu žemės dirbimu. Giliausiame (30–35 cm) tirtame dirvožemio sluoksnyje didžiausias drėgmės kiekis nustatytas sekliai purentuose laukeliuose.

Tyrimai atlikti 2015 m. Aleksandro Stulginskio universiteto Bandymų stotyje. Eksperimento dirvožemis – dulkiško lengvo priemolio giliau glėjiškas pasotintasis palvažemis (PLb-g4). Tyrimų tikslas – įvertinti necheminės piktžolių kontrolės sistemų įtaką cukrinių runkelių pasėlio piktžolėtumui ekologinės žemdirbystės sąlygomis. Tirtos tvarios necheminės piktžolių kontrolės sistemos: • tarpueilių purenimas (kontrolinis-palyginamasis variantas) (P); • tarpueilių išpjovimas ir mulčiavimas piktžolėmis (IM); • tarpueilių išpjovimas ir mulčiavimas įsėtais persiniais dobilais (PD); • tarpueilių išpjovimas ir mulčiavimas įsėtomis baltosiomis garstyčiomis (BG); • tarpueilių išpjovimas ir mulčiavimas įsėtais vasariniais miežiais (VM); • tarpueilių garinimas karštais vandens garais (VG). 2015 m. sausomis augalų vystymosi sąlygomis cukriniai runkeliai prastai konkuravo su piktžolėmis, todėl ir alternatyvios piktžolių kontrolės sistemos nebuvo efektyvios. Kontrolinio varianto laukeliuose piktžolių skaičius ir biomasė dažniausiai buvo mažesni nei kitų variantų laukeliuose. Per cukrinių runkelių vegetaciją kontroliniuose laukeliuose piktžolės sukaupė 121,71 g m–2 sausosios biomasės, kai kitų variantų laukeliuose – iki 2–3 kartų daugiau. Kiek mažiau sausosios biomasės piktžolės sukaupė tarpueilius mulčiavus vasariniais miežiais – iki 179,18 g m–2. Didžiausią sausosios biomasės kiekį cukrinių runkelių tarpueiliuose išaugino vasariniai miežiai – 338,96 g m–2, todėl jais padengtuose cukrinių runkelių tarpueiliuose buvo mažiausia piktžolių.
