Changes in soil properties after residue incorporation in Alfisol of Vindhyan plateau

Abstract

Soil respiration & catalase activity involves different sets of chemical, physical, and biological processes. Soil respiration processes are, in turn, influenced by an array of factors. The factors are organic and inorganic carbon, temperature, moisture, nitrogen, soil texture, soil pH, and soil EC and land use and management practices. Cumulative CO2 evolution curves obtained from the seven soils treated with the equivalent of 4 and 40 tons per acre, respectively, of finely ground hay having a C/N ratio of E. crassipe (36:1), wheat straw (64:1) and rice straw (47:1). The application of validamycin at 240 ml mg -1 caused a significant decrease (14%) in soil catalase compared with the control. Rice straw + wheat straw + E. crassipe treatment shows high soil respiration in different as compared to soil of. So rice straw +wheat straw + E. crassipe favor microbial community may be due to secretion of favorable. Crop C/N ratio and ash content have a significant relationship with soil respiration as it is affects soil mineralization of organic carbon.
