Overview

Field experiment demonstrates increased soil fertility and crop yields under legume-microbial systems in degraded chernozem, indicating strong potential for regenerative agriculture.

Key Points

  • To evaluate the efficacy of combining legume crops, mixed sowing systems, and microbial biopreparations for restoring degraded chernozem soil fertility and enhancing crop productivity.
  • Conducted a 3-year field experiment from 2022 to 2024 evaluating legume crops, mixed sowings, and microbial biopreparations (Azotokhelp, Helprost Universal, Phytocid, and Organic-Balance).
  • Assessed changes in soil properties, biological indicators, and crop productivity using agrochemical, microbiological, and statistical analysis methods.
  • The integrated B5 treatment increased humus content by 31%, readily available nitrogen by 40%, total soil microorganisms by 3.2-fold, nitrogen-fixing bacteria by 6.4-fold, and dehydrogenase activity by 4.1-fold.
  • Crop productivity improved significantly under the B5 regimen, increasing soybean yield by 75%, chickpea yield by 64%, and lucerne green mass yield by 59%, along with enhanced protein content.
