Effect of Sewage Sludge Compost Usage on Corn and Faba Bean Growth, Carbon and Nitrogen Forms in Plants and Soil

Sewage sludge is an effective fertilizer in many soil types. When applied as amendment, introduces, addition to organic matter, plant nutrients into the soil. for cropland a fertilizer, mass loading of sewage customarily determined by inputs N and/or P required support optimal growth and successful harvest. This study aims examine changes matter contents nitrogen forms sludge-amended soils, well corn faba bean plants. The main results indicated that there were higher responses yields when was added. Levels carbon after maize harvest decreased significantly harvesting beans, amended soils than unmodified indicating residual effect NO3−-N concentrations generally during period, but this trend not apparent amounts NH4+-N close period or harvest, while they period.
