Sažetak
Several European Union policies (e.g. Green Deal, Climate law, Biodiversity Strategy 2030, Farm to Fork) have a goal to transform the agricultural systems and one of the goal is fertilizers reduction. Nature based solutions (e.g. green manure) can help in restoring soil quality for enhanced agricultural productivity and sustainability. A two-year research (on the Dalibor Jurina familly farm in Veliki Zdenci, Bjelovar-Bilogora County) was conducted to test real fallow and green fallow on the improvement of the soil quality. Experiment is conducted in random block layout with four treatments (I. black fallow ; II. Black fallow + green manure ; III. Crops (2021-corn & 2022-soybean) + green manure ; IV. crops (2021-corn & 2022-soybean) without green manure on plots of 10 x 35 m in four repetitions on Pseudogley on the plain in semi-humid conditions. Results confirmed that green manure affects changes in the soil reaction, the stability of structural aggregates, and C/N ratio. Soil compaction is reduced in green manure plots over a period of two years (autumn 2020 - autumn 2022). Moreover, there is no correlation between green manure and maize yield in the first year of the study. Results reveal that the maize yield was lower in the treatment where green manure was applied. In the second year of the study, the yield of soybean was higher in the treatment with green manure. It is necessary to continue research in order to determine changes in physical and chemical properties and to observe the influence of green manure on them, as well as on the yield of cultivated crops.
