A diverse topography along with deforestation, changing climatic conditions, long-term human settlement, overuse of agricultural lands without sustainable planning, cultural difficulties in accepting conservative land management practices, and wrong political decisions have increased the vulnerability of many soils to degradation and resulted in a serious decline in their functional capacity. A progressive reduction in the capacity of soils to support plant productivity is not only a threat in the African continent and its large desert zone, but also in several parts of Central and Southeastern Europe (CASEE). The loss of soil functions throughout CASEE is mainly related to the human activities that have profound influence on soil dynamic characteristics. Improper management of soils has made them more vulnerable to degradation through water and wind erosion, organic matter depletion, salinity, acidification, crusting and sealing, and compaction. Unmitigated degradation has substantial implications for long term sustainability of the soils’ capability to support human communities and resist desertification. If sustainable agricultural and land management practices are not identified, well understood and implemented, the decline in soil quality will continue and probably accelerate. The lack of uniform criteria for the assessment and evaluation of soil quality in CASEE countries prevents scientific assessments to determine if existing management practices are leading to soil quality improvement, or if not, what management practices should be recommended to mitigate and reverse the loss of soil health.

This paper provides an overview of the progress of tillage in Hungary. The local and international impacts on the national practice are summarized, and some adoption of the conservation tillage results is presented concerning Hungary. The interest in conservation agriculture in Hungary dates back almost 120 years; however, any significant changes only occurred in the last 50 years. Interestingly, the factors of progress and restraint in tillage have appeared simultaneously over the years. Among the factors restraining tillage progress, the most retarding were the beliefs that have existed for many decades, as soil conservation was not considered nor was the need to mitigate climate-related hazards. Progress was driven by the commitment to soil protection, the opportunity to raise farming standards, and the need to mitigate climate-related threats. Since the average yield in Hungary was usually sufficient for the domestic need, the main objective of crop production was to avoid yield loss. Long-term experimental data and monitoring results were considered for this study. The impacts of new tillage solutions, elaborated in foreign countries, on tillage modernization were reviewed. The experiences and first results in no-till (direct drilling) and strip-tillage showed that difficulties can gradually be reduced through site-specific technology solutions. The need for subsoiling is not a matter of debate nowadays but rather the timing of operation and the investigation of the duration of the effects. Due to its complex advantages, tine tillage occupies an increasing rank among soil conservation systems. The area of ploughed soils has decreased; however, improved implementation is required.

A decline in rainfall as a source of agricultural water has affected and will continue to affect sustainable crop production globally including in Hungary. Conservation of the greatest water reservoir is important for the sustainable development of agriculture in Hungary. The objective of this study was to evaluate the effects of the different tillage methods on soil moisture content, grain yield, and root weight of wheat (Triticum aestivum) and sunflower (Helianthus annuus) under rainfed conditions. A field study was conducted at the Józsefmajor Experimental and Training Farm (JM) of the Hungarian University of Agriculture and Life Sciences near Hatvan. The experiment consisted of six tillage treatments: disking (D, 16 cm), shallow cultivation (SC, 20 cm), no-till (NT), deep cultivation (DC, 25 cm), loosening (L, 45 cm), and plowing (P, 30 cm). Soil moisture content (SMC) was measured monthly, and grain yield and root weight were measured at the end of the cropping period. Our results showed no significant difference in SMC between conservation and conventional tillage methods in 2018. However, in 2021, greater SMC was significantly conserved under NT compared to P. Regarding the sampling date, a significant increase in moisture with time was observed. A significantly lower SMC was observed on 3 June 2019 between L and D. while on the 9 September 2020, SMC significantly differed between P and all the other treatments (D, SC, NT, DC, and L). Interestingly in 2018, SMC was significantly lower at 10–20 cm depth between L and D. Notably the effect of depth on SMC was observed as moisture significantly increased with increasing depth in all tillage treatments. Root weight was greatest at DC (1.54 t ha⁻¹) in 2018 and under L (3.89 t ha⁻¹) in 2021. Similarly, wheat grain yield was greatest at DC (2.48 t ha⁻¹) in 2018, while sunflower yield in 2021 was greatest at L (3.86 t ha⁻¹). It is comprehensible that conservation tillage methods such as L and NT can increase SMC and grain yield.

In addition to the dry (D) and rainy (R) seasons, a combination of the two i.e., rainy-dry (RD) and dry-rainy (DR), can also be observed in one year. The effects of the dry (D) and rainy (R) on soil are known, hence we hypothesized that the effects of the rainy-dry (RD) and dry-rainy (DR) periods on soil may differ from the former assessments. The aim of the study is to investigate the effect of six tillage treatments (ploughing—P, disk tillage—DT, loosening—L, tine tillage (a deeper—T and a shallower—ST) and no-till—NT) on earthworm abundance and crumb ratio during a long-term research (16 years) on Chernozems. The results related to the four year-groups (D, R, RD, and DR) with different residue cover. Seven degrees of cover ratio (between 12.5% and 62.5%) were selected on stubbles. Higher cover ratio (≥52.5%) improved water conservation, increased earthworm abundance (31 and 41 ind m^–2) and crumb (78 and 82%) ratio (p < 0.01). R year came first in the rank of water content and earthworm abundance and DR proved to be more favorable for crumb formation. Considering the rank of soil tillage treatments, ST takes first place in evaluation of soil water content (SWC) and crumb ratio, and NT for earthworm abundance.

The aim of this study was to determine the environmental suitability of conservation tillage systems. A 3-year experiment was conducted in Croatia, to study the effects of different tillage treatments on soil properties, with the following: deep (DC), shallow tine cultivation (SC) and ploughing (P). Soil penetration resistance (SPR) was significantly greater in P compared to DC in all three years. In 2016, it was found at 30–40 and 40–50 cm; in 2017 at 10–20 cm; in 2018 at 0–10 and 10–20 cm. However, SC was significantly greater at 20–30, 30–40 and 40–50 cm compared to P and DC in 2017. The greater surface coverage in DC and SC (>30%) as compared to P (<1%) provided significantly higher soil moisture content (SMC) in maize (2016) and soybean (2018). In 2017, SMC in SC was significantly lower than in P and DC. Regarding all the 3 years, the agronomic structure in DC and SC had significantly greater crumb ratio compared to P, whereas P had significantly higher dust ratio than DC and SC. Throughout the 15 measurements, DC provided the most favorable soil habitat (11 occasions out of 15). In 2017, the earthworm abundance was significantly higher in DC compared to SC. In all the three years, DC resulted the highest yield, however the difference was not significant. Higher surface coverage and SMC positively impacted the ratio of agronomic structure (decreased dust and increased crumb ratio) and earthworm abundance. It can be concluded that DC and SC provided greater soil coverage which positively affected SPR, SMC, agronomic structure and earthworm abundance as compared to P.
