  We investigated the effects of fatty wool and wheat straw mulch on soil moisture, soil temperature values, and berry yield development in an outdoor tomato experiment on clay loam soil using small plot trials. In terms of soil moisture, both mulching treatments and the measurement dates (8 occasions) showed significantly more favorable values compared to the control tomato plants. No significant differences were found among the treatments for soil temperature, only between the measurement dates. The berry yield for both types of natural mulch exceeded the control values (4.04 kg/plant), with statistically significant differences observed between the untreated (control) and mulched (straw and wool) treatments. No significant difference was noted between the straw (7.54 kg/plant) and wool (6.69 kg/plant) mulched treatments. However, in the case of the wool mulch several practical insights have been provided for future applications, inspiring further research work.

  In the present study, the effects of reduced and conventional tillage on the grain yield of winter wheat were investigated during the extremely dry 2021/2022 growing season in Karcag, Hungary. The research was conducted within the framework of the local long-term soil tillage experiment, where the reduced tillage plots have been managed since 1997 using non-inversion, loosening-based primary tillage and mulch farming. The soil of the experimental site is a clayey loam textured, deep-saline meadow chernozem. The experiment was carried out in four replications on meso-plots (1890 m²). For the evaluation of the results, key local meteorological data were considered, including precipitation totals, temperature data, and potential evapotranspiration (PET), from which the climatic water balance (CWB) was calculated. Descriptive statistical parameters were determined, and following a (positive) homogeneity test, a one-way analysis of variance (ANOVA) was performed. Based on the results, reduced tillage achieved an experimental average of 4.45 (±0.10) t ha⁻¹, significantly outperforming (p<0.05) the conventional, moldboard ploughing-based tillage yield of 3.62 (±0.29) t ha⁻¹. The processing and evaluation of meteorological data revealed that the 2021/2022 growing season in Karcag was extremely dry for winter wheat production, particularly during the critical spring vegetative and especially the reproductive stages. This drought intensified the differences in soil water management between reduced and ploughing-based conventional tillage systems. Based on these findings, the previously described soil moisture-conserving effect of reduced tillage was confirmed, and it was concluded that significant yield surpluses can be achieved with reduced tillage in winter wheat production during drought years.

  In addition to traditional tillage systems, more biologically based farming systems have emerged. New tillage systems can be developed using various scientific results and technical technological possibilities. This research started six years ago and the results of the last two years are presented here. In the examination, four different tillage systems have been established on the same site. Measuring penetration resistance is a common technique for evaluating field effects and the effects of tillage systems on soil can be evaluated using this value.
  The performed measurements show that conventional tillage systems based on ploughing develop a fundamentally different structure in the soil section up to 50 cm than the three different no-tillage systems examined.

  Today, environmental monitoring is increasingly important in arable crop production due to the importance of weather, sustainable nutrient and water management. This paper presents a new innovative technology based on wireless data link and transmission and its results for monitoring soil ammonia emissions using Internet of Things (IoT) technology based on the measurement of environmental characteristics could be a practical method in the future. It is a monitoring system for sustainable and environmentally friendly crop production. The sensors used will ensure the monitoring of soil ammonia emissions, a method that provides fast and accurate monitoring. The results show a periodic trend in NH3 fluxes, with higher amounts in the spring (warmer) periods after nitrogen fertilisation. Results of multivariate linear regression analyses indicate that soil moisture, temperature, humidity and air pressure significantly influence NH3 emissions.
