After lentil harvest, lowest bulk density, highest total and aeration porosities and hydraulic conductivity of soil were obtained with the method of `fall plowing, sweep + harrowing in spring and seeding lentil with cereal drill`. The analysis of samples taken after tillage for wheat, showed that the method of `broadcasting lentil seed and plowing under and, following harvest of lentil offset disking for wheat seedbed preparation` produced highest yield and emergence of wheat and lowest bulk density, highest total and aeration porosities and hydraulic conductivity of soil.
