Long-Term Effect of Puddling and Fertilizer Use in Rice-WheatCowpea Sequence on Structural Properties of Soil

Rawat, Ruchi Tripathi, Nand Ram

Abstract

Effect of puddling; fertilizers and manures on puddling index, bulk density, aggregate stability, air-filled porosity and penetration resistance of soil was evaluated in a 20-year old experiment under rice-wheat-cowpea on a Hapludoll. Bulk density increased and water stable aggregate decreased as a result of puddling. Bulk density and cone index values showed the development of a hard pan at 0.15 m depth from the surface.
