Installation of subsurface tile lines in poorly drained soils is a beneficial management practice that enhances crop productivity. In some instances, however, they can contribute to offsite losses of agricultural chemicals and sediment in drain flow. Movement of these materials through soil macropores (earthworm burrows and cracks) has been shown to contribute to this phenomenon. In order to de...

BACKGROUND: For the cultivation of agricultural crops, technology basic dump tillage is widely used. More than 40% energy resources are spent on it, due to traction resistance working bodies general-purpose plows. The technological process plowing with such has not changed much historically. Pruning soil layer carried out a ploughshare, crumbling and turning blade, stability movement body provi...

Root penetration resistance increased maize roots penetrating 1.2–1.5 times deeper. had the greatest available storage 56 cm smallest runoff in both years. Increases infiltration resulted moisture retention up to 60 depth. productivity a positive net benefit. Closing yield gap enhancing efficiency rainfed prod...
