Model of optimal soil seed layer by agrophysical parameters

Goal. To develop a model of the soil seed layer with optimal parameters structure density in subseed and structural components supraseed for crops depending on size their seeds. Methods. Field (small-plot), mathematical-statistical, computational. Results. As result conducted research composition sowing taking into account requirements seeds are defined. For plants small (millet) predominant aggregates should range from 0.5 to 7 mm, medium (spring wheat) large (corn) — 1 10 mm; vary 1.1 1.3 g/cm3. In course research, expediency differentiation layers creation agrophysical each them (immediately before crops) was proved. Improvement germination, growth development plots established. Creating, sowing, contributed increasing length diameter roots corn by 29% 22%, spring wheat 17% 19%, millet 12% 8% compared control areas where used standard technology. Studies showed an increase crop yields tillage technology: sizes, yield 50%, sizes 25% 35%, respectively. Conclusions. According allows best conditions germination emergence seedlings crops, which turn is strong argument favor harvest.
