Residual Soil Nitrogen and Nitrogen Response of Corn on Sandy Loam Soil
Groundwater contamination is an ever-increasing concern on a national level as well as locally. Increasing amounts of nitrate-nitrogen (NO3-N) being delivered by rivers, including the Mississippi, have resulted in an oxygen-depleted area or hypoxic zone in the Gulf of Mexico. (Turner and Rabalais, 1994b). This nutrient loading has caused nitrogen-limited phytoplankton to bloom. Decom-position o...
متن کاملNitrogen mineralization potential of three animal manures applied on a sandy clay loam soil.
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...
متن کاملPersistence and carryover effect of oxyfluorfen residues in red sandy clay loam soil
A Field experiments were conducted for two years at Agricultural Research Station, Bhavanisagar of Tamil Nadu Agricultural University, Coimbatore, India during kharif season of 2010 and 2011 to evaluate the new formulation of oxyfluorfen (23.5% EC) on weed control in onion and their residual effect on succeeding crops. Herbicides are being chemical in nature, excessive and repeated use may pose...
متن کاملFate of manure phosphorus in a weathered sandy clay loam soil amended with three animal manures.
Laboratory incubation was conducted for 120 days to study the fate of phosphorus in poultry (PM), cattle (CM) and goat manures (GM). Phosphorus mineralized from manure was dependent on total P, Al and Fe content. Manures improved P availability in the order: PM>CM>GM; however, the highest amount of P was fixed or immobilized between 10 and 70 days of incubating with CM and GM. Fixation and immo...
متن کاملBacteriological Quality of Surface and Subsurface Runoff from Manured Sandy Clay Loam Soil
The bacterial quality of surface waters determines their acceptability for both drinking and recreational uses. Since livestock activities have been implicated as sources of fecal contamination, information on the bacterial quality of runoff from manured cropland is required. Bacteriological parameters (total coliform [TC], fecal coliform (FC], and fecal streptococcus [FS]) were monitored in sp...
