Research Interests

Studied long-term effect of tillage practices (no-tillage and conventional tillage) and N sources (manure and fertilizer) on:

                1. Soil organic matter fractions

      2. Soil aggregation and physically protected C and N.

                3. Soil N supply capacity.

      4. Crop yield

          Assessed carbon and nitrogen release (flush) with repeated wetting and drying cycles.

Kinetic assessment of carbon and nitrogen mineralization rates.

          Measured biological properties for a soil quality assessment.
