The kinetics of phosphorus (P) desorption in soils is important from plant nutrition and environmental perspectives. An experiment was conducted on the field plots that received 100 t ha of solid dairy manure 1 (DM), sewage sludge (SS), or urban solid waste compost (UC) and one rate of chemical fertilizer (CF) for 1, 3 or 5 consecutive years to investigate the residual and cumulative effects of...

Nutrient losses due to leaching, volatilization and fixation and the activated risk of nitrate leaching after fertilizer addition to the soil may be reduced through the use of slow-release fertilizers. Turmeric, a long duration and high yielding commercial crop consumes greater amount of nutrients from the soil as well as from applied fertilizers for a prolonged period. A field experiment was c...

nterest in organic fertilizers is growing in the greenhouse industry, but experience and trials are not keeping up. There is little information available on how well the new types of fertilizers provide nutrition for plants compared to traditional water-soluble chemical fertilizers. The most widely available “organic” fertilizers for application like traditional water-soluble fertilizers are fi...

Understanding the dynamics of N forms applied as manure is germane for appropriate rate and timing of applications of manure. Manure characterization and laboratory incubation were conducted for 120 days to study the mineralization of poultry, cattle and goat manures. Results showed that manure properties differ. Net immobilization of N was recorded for goat and cattle manures while poultry man...
