Sažetak
The negative environmental impact of conventional agriculture threatens agroecosystem stability and food security. In this context, searching for optimal soil management is crucial for maintaining and improving soil functions. This work aims to determine the impact of conventional tillage (CT) and reduced tillage (RT) on Cambisols in a semi- humid environment in Marija Magdalena (Croatia). Under each tillage treatment, subplots were biochar – B (40 t ha-1), farmyard manure – FYM (40 t ha-1) and control - C. The impact was assessed on physical soil properties and maize (Zea mays) yield. Soil bulk density (BD) at 0-15 cm depth was significantly lower in RT-B when compared to the CT-B. At 15 – 30 cm depth, BD was significantly lower in all RT sub-treatments than in CT. Penetration resistance (PR) did not exceed 2 MPa. At 0-15 cm, PR was significantly lower in RT-C than in CT-C and CT-FYM plots. Between 15-30 cm, PR was significantly higher in CT-B and CT-C than in the other treatments. Soil water content (SWC) was high in RT treatments at 0-15 cm . At 15-30 cm, SWC was significantly lower in CT-B than in RT-B. Water-stable aggregates were higher in B and FMY plots under RT than under B and FMY plots under CT. Moreover, maize grain yield was higher in RT treatments than in CT. Specifically, FYM addition with CT showed a better impact than FMY with RT. Maize respond oppositely when compared biochar and tillage treatments, RT-B was better management than CT-B. Regarding short-term results, we can conclude that RT is an advisable alternative for CT due to its positive impact on soil physical condition. Efficient management for stable yields and amendment recommendations could be determined by implementing this research over an extended period.
