Microbial soil additives and plant biostimulants contain substances and microorganisms that can enhance stress tolerance in plants and increase the yield and quality of the crop. The interest in such inputs for sustainable and agroecological farming systems has led to the development of a range of products. The aim of the study was to determine the effects of some microbial soil additives (MSADs), plant growth promoters (PGPs) and biological control agents (BCAs) on photosynthetic efficiency, canopy vegetation indices and yield of common buckwheat (Fagopyrum esculentum Moench), an under-utilised nutraceutical crop. The study showed that soaking the seeds in the BCAs Pythium oligandrum and Bacillus subtilis, on their own, had significant effects on the yield of the buckwheat. Increases in chlorophyll a fluorescence indices were observed in plants grown from seeds soaked in a solution containing P. oligandrum (ET0/RC) and also in soil treated with the MSAD UG Max (ABS/RC, TR0/RC). Treatment with either of the two MSADs also increased the normalised differential vegetation index (NDVI). Soaking the seeds in PGPs combined with BCAs affected only the chlorophyll a fluorescence parameters, whereas the combined treatment of spraying the plants with PGPs and treating the soil with MSADs affected not only the chlorophyll a fluorescence parameters (FV/FM, ET0/RC, DI0/RC), but also indicated a tendency for a decrease in the leaf area index (LAI) (p = 0.058) and the NDVI (p = 0.186). The correlations between grain yield, chlorophyll a fluorescence parameters and vegetation indices of the canopy were discussed.

The aim of this study was to estimate complete extruded dry food for adult dogs, with a particular focus on: mineral profiles and ratios and the division into breed size. Dog foods were subjected to chemical analyzes to determine the content of macroelements and microelements. Additionally, the presence of heavy metals was verified and mineral ratios were estimated. The material for the research consisted of 15 randomly selected industrial household maintenance foods for adult dogs (five for large breed dogs, five for small breed dogs and five for all breeds dogs). All analyzed feeds met the FEDIAF recommended minimum recommended levels of microelements and macroelements, although the potassium level in 33% of the feeds analyzed was below the recommended minimum. 20% of the feeds tested exceeded the permissible quantitative ratio of calcium to phosphorus. In none of the tested feeds no heavy metals (Ni, Cd, Pb) were found. When choosing a feed, always pay attention to the label and carefully analyze the component of the product.

In addition to properly balancing nutritional value in accordance with the needs of a dog, estimating the microbiological quality of dog food is crucial in providing healthy and safe foods. The aim of this study was to examine the quality of dry food for adult dogs, with particular reference to: (1) evaluating the nutritional value and compliance with nutritional guidelines for dogs, (2) comparing the nutritional value of dog foods, with particular emphasis on the division into cereal and cereal-free foods, and (3) evaluating their microbiological safety. All thirty-six evaluated dry dog foods met the minimum European Pet Food Industry FEDIAF requirement for total protein and fat content. The total aerobic microbial count in the analyzed dry dog foods ranged from 2.7 × 102 to above 3.0 × 107 cfu/g. In five (14%) dog foods the presence of staphylococci was detected; however, coagulase positive Staphylococcus (CPS) was not found. Mold presence was reported in one cereal-free dog food and in six cereal foods. In none of the analyzed foods Enterobacteriaceae were found, including coliforms, Escherichia coli and Salmonella spp. Bacteria of the genus Listeria and Clostridium as well as yeasts were also not detected. In conclusion, the evaluated dry dog foods had varied microbiological quality. The detected number of microorganisms may have some implications for long-term consumption of contaminated food. The lack of European Commission standards regarding the permissible amounts of microorganisms in pet food may result in insufficient quality control of these products.

The chemical composition of 4 spring wheat species was analyzed: einkorn (Triticum monococcum) (local cv.), emmer (Triticum dicoccon) (Lamella cv.), spelt (Triticum spelta) (Wirtas cv.), and common wheat (Triticum aestivum) (Rospuda cv.). Mean emmer and einkorn yield was significantly lower than that of common wheat. The analyses of the wheat grain included the content of total protein, crude ash, crude fat, crude fibre, carbohydrates, phosphorus, potassium, magnesium, calcium, copper, iron, manganese, and zinc. The grains of the tested ancient wheats were richer in protein, lipids, crude fibre, and crude ash than the common wheat grains. The significantly highest levels of crude protein, ether extract, and crude ash were found in einkorn. As the protein concentration in the grain increased, the calcium, magnesium, and potassium levels increased, and the zinc and manganese levels decreased. Genotypic differences between the studied wheats were reflected in the concentrations of the minerals and nutrients, an observation which can be useful in further cross-linkage studies. Dough made from common wheat and spelt flour showed better performance quality classifying it to be used for bread production. In turn, flour from emmer and einkorn wheat may be intended for pastry products, due to short dough development time and constancy as well as high softening.

Nowadays, dogs are usually equally treated with other family members. Due to the growing caregivers’ awareness, the pet foods industry is changing dynamically. Pet foods are manufactured with a myriad of ingredients. Few authors of scientific papers deal with the topic of foods products’ safety for pet animals, assessed from the perspective of their caregivers. Despite the many methods of producing foods of the highest quality, there are still cases of contamination of pet foods and treats. In the case of dried chews for dogs, bacteria of the genus Salmonella are the most common risk. In the case of both dry and wet foods, in addition to many species of bacteria, we often deal with mold fungi and their metabolites, mycotoxins. This article presents selected microbiological risks in dog foods and treats, and analyzes the Rapid Alert System for Food and Feed (RASFF) system (2017–2020) for pathogenic microorganisms in dried dog chews, treats and foods. In this period, pet food-related notifications were registered, which were categorized into different types. Analyzing the RASFF notifications over the period, it has been shown that there are still cases of bacterial contamination of dog foods and treats, while in terms of the overall mycotoxin content, these products may appear safe.

This work presents the results of the study of changes of the potential contamination of soybean agrophytocenosis in grain-row crop rotation by using different systems of farming and typical black soil tillage. It was established that in the upper 0–5 cm layer of soil there are on average 393–671 million pieces of weed seeds. which is 33.6–43.0% of the total number in the layer of soil 0–20 cm. It was established that the use of periodical moldboard and superficial basic soil tillage had no impact on reducing the potential contamination of typical black soil compared to the variant of differentiated tillage. During subsurface plowing the total number of seeds in the soil layer 0–20 cm increased by 13.5–25.8% compared to differentiated tillage. In the variants of ecological and biological farming systems the number of weed seeds in the layer 0–5 cm was 11.3–19.6% higher compared to the intensive farming system. Based on monitoring of the species composition of the weed seeds bank it was established that in the arable layer of the soil the largest share are annual dicotyledonous – 48–62%. annual monocotyledonous – 30.2–44.6%. perennial – 0.9–3.3% of the total number. It was proved that under the intensive system of farming the yield of soybean variety Silesia increased on average from 10.2 to 147% compared to the ecological and biological system of farming. During the biological system of farming soybean yield did not exceed 1.0–1.8 t/ha. Therefore. the industrial and ecological system of farming had the greatest impact on reducing the potential weediness of the soybean agrocenosis during the growing season. During the biological system of farming crop yields decrease due to the accumulation of weed seeds in the topsoil and formation of high actual weediness of the soybean agrocenosis.

The aims of the present work are to estimate the nutritional value and to evaluate and compare the levels of macroelements (Ca, P, K, Na, Mg), microelements (Fe, Zn, Mn, Cu), heavy metals (Co, Cd, Pb, Mo, Cr, Ni), and their ratios in extruded complete foods for adult dogs, their compatibility with nutritional guidelines, as well as food profile similarity. Basic composition was determined according to Association of Official Analytical Chemists (AOAC). Analyses for elements were performed using an atomic absorption spectrometer. All the evaluated dry dog foods met the minimum recommended levels for protein and fat. Eighteen tested dog foods (60%) did not meet at least one recommendation of nutritional guidelines. Four dog foods exceeded the legal limit of Fe and five foods exceeded the legal limit of Zn; in one of them, Zn level was almost twice higher. Dog foods with insect protein exceeded the legal limit for Mn content. Eight dog foods had an inappropriate Ca:P ratio. Heavy metals were below detection limit in all analyzed dog foods. The results seem to show the need for regular feed analyses of the elemental composition in raw materials before introducing supplementation and for the monitoring of the mineral composition of finished pet food.

The study analyzes the influence of plant growth promoters and biological control agents on the chemical composition and antioxidant activity (AA) in the sprouts of buckwheat. The AA of cv. Kora sprouts was higher than cv. Panda, with 110.0 µM Fe2+/g (FRAP—Ferric Reducing Antioxidant Power), 52.94 µM TRX (Trolox)/g (DPPH—1,1-diphenyl-2-picrylhydrazyl), 182.7 µM AAE (Ascorbic Acid Equivalent)/g (Photochemiluminescence—PCL—ACW—Water-Soluble Antioxidant Capacity) and 1.250 µM TRX/g (PCL—ACL—Lipid-Soluble Antioxidant Capacity). The highest AA was found in the sprouts grown from seeds soaked in Ecklonia maxima extract and Pythium oligandrum (121.31 µM Fe2+/g (FRAP), 56.33 µM TRX/g (DPPH), 195.6 µM AAE/g (PCL—ACW) and 1.568 µM TRX/g (PCL—ACL). These values show that the antioxidant potential of buckwheat sprouts is essentially due to the predominant hydrophilic fraction of antioxidants. The AA of the sprouts was strongly correlated with total polyphenol content.

This study investigated the influence of biological control agents and plant growth promoters on the chemical composition of the cultivars Panda and Kora buckwheat sprouts. Before sowing, seeds were soaked in solutions containing Bacillus subtilis bacteria, Pythium oligandrum oospores, Ecklonia maxima algae extract, and/or nitrophenols. The sprouts of the Panda displayed higher levels of protein, fat, and dietary fiber fractions than the Kora. Measurable effects of biological control agents (BCAs) and plant growth promoters (PGPs) on the chemical composition of sprouts were also confirmed. Soaking the seeds in a solution containing P. oligandrum oospores resulted in a decrease in the level of crude ash in sprouts, while the addition of nitrophenols increased the level of both crude ash and protein. We also found statistically significant effects of interactions between the cultivar and BCA and/or PGP for each of the examined components.

The aim of the study is to compare the content of nutrients, including selected macro- and micro-elements, in musculus semitendinosus and offal (liver, heart, kidneys, tongue, brain) derived from animals (calves, beef cattle, and lambs) that are fed and maintained in organic production conditions. The experimental material consisted of 60 animals: 20 calves, 20 beef cattle, and 20 lambs. This research was carried out using Limousin cattle and Ile de France sheep. From the obtained results, it is concluded that the physicochemical and nutrient composition varied significantly among the organs and species studied. Almost all byproducts are a rich source of trace elements, whose levels/amounts are usually much higher in byproducts such as offal than in muscular tissues. Also, for economic reasons (profitability), byproducts (offal) can be commercially sold for human and animal nutrition. Byproducts are processed and incorporated into many food products and provide competitive nutritional value for use by tissues and muscles (vitamins and elements).

In this study, leaf extracts from the Green Globe cultivar of artichoke (Cynara scolymus L.), a herbaceous plant of the Asteraceae family, were analyzed to determine the levels of basic nutrients, selected macroelements (K, P, Ca, Mg, and Na) and microelements (Zn, Fe, Mn, Cr, Pb, Cd, and Ni), and their ratios. The antioxidant activity (aa) of the extract was evaluated using ABTS˙+ and DPPH˙+ radicals and the ferric reducing antioxidant power assay (III) (FRAP). Total polyphenolic content was also determined. Macroelement concentrations in the artichoke leaf extract can be presented in descending order as follows: K > P > Ca > Mg > Na. Microelement content in the extract was as follows: Zn > Fe > Cr > Mn. We determined the ratios of elements in artichoke leaf extracts and compared them against the recommended dietary allowance, adequate intake, or tolerable upper intake level. Mean total phenolic content in artichoke leaf extracts was high – 2795 mg CAE/100 g dry matter (DM). The ABTS˙+ assay showed a very high ability of artichoke extract to scavenge free radicals (79.74%), and the antioxidant capacity measured at 1060.8 Trolox/1 g DM. The results show that artichoke extract is a valuable source of minerals and antioxidants that could have applications in the prevention of chronic non-communicable diseases caused by oxidative damage.

Although the medicinal properties of berry fruit are well known, there is relatively little information available concerning the applications of other parts of berry plants. Thus, in this study we determined the nutritional value of the leaves of selected berry species and their possible application in health promoting diets. The levels of nutrients, and macro- and microelements in the leaves of four species collected from allotment gardens in the city of Szczecin, Poland (53°26′17″ N, 14°32′32″ E; altitude 7 m a.s.l.) were identified: raspberry ( Rubus idaeus L.), blackberry ( Rubus fruticosus L.), chokeberry ( Aronia melanocarpa L.), and sea buckthorn ( Hippophae rhamnoides L.). Sea buckthorn leaves were the richest source of protein, raspberry leaves had the highest levels of lipids, and the leaves of all four species studied were a rich source of crude fibre and dietary fibre fractions. Desirable Ca:P and Na:K ratios indicated their potential as a good source of minerals essential to bone formation and the treatment of hypertension. Sea buckthorn leaves contained high but also safe Fe levels (within recommended WHO limits) and, therefore, may become an alternative rich source of this element.

The leaves of sea-buckthorn (Hippophae rhamnoides L.) can be a rich source of nutrients and biologically active substances. Their levels depend on growing conditions, agricultural technology and climate. The studies however, mainly focus on nutritious value of fruit and seeds and there is shortage of the information regarding to buckthorn leaves. The aim of the experiment was to determine the effect of symbiotic mycorrhizal fungi on the chemical composition and antioxidant activity of sea-buckthorn leaves. The study was conducted in 2014 and 2015 at the Experimental Station in Lipnik, Poland. Mycorrhization improved the nutritional value of leaves of sea-buckthorn by increasing levels of total protein (3%), N free extract (1%), Ca (9%), Na (16%), Fe (18%), Cr (34%), and partially elevating antioxidant activity by increasing the concentration of polyphenols (7%). Leaves of 'Habego' had a higher nutritional value, containing more total protein (4%), crude fat (7%), crude fiber (30%), and all fractions of dietary fiber. 'Hergo' had more beneficial levels of minerals (P-27%, K-67%, Mg-4%, Na-30%, Zn-8%, and Cr-21%), polyphenols (51%), total flavonoids (35%), carotenoids (10%), and L-ascorbic acid (8%), as well as higher antioxidant activity (40%). The results of our study partly confirmed the earlier scientific reports on the impact of mycorrhiza on the chemical composition of plants. However, it is not possible to compare our results with data on berry plants, including sea-buckthorn, due to the lack of information in the literature.
