Long-term application of organic manure and nitrogen fertilizer on n 2 o emissions, soil quality and crop production in a sandy loam soil the n 2 o emission from agriculture is mainly derived from the microbial processes of nitrification and denitrification in soils. Several long-term manure application studies have illustrated its ability to slow or reverse declining soil organic levels of cropland: manure and soil quality.
First year available organic nitrogen is estimated at 33 percent and ammonium nitrogen available first year can range from 15 to 75 percent depending on application timing organic producers need to have an understanding of plant available nitrogen derived from compost or manure sources.

This effect of manures on soil organic c was not due to mineral fertilizers lessening soil organic c contents, as we observed that soil organic c levels also increased following mineral fertilizer application, which enhanced crop production and increased the input of crop residues (ie roots and stubbles) into the soil (paustian et al, 1997) however, in the nk and ck treatments, which did not receive added p, the soil organic c content was significantly lower than in the other treatments. Journal of agricultural technology 2011, vol 7(5): 1549-1559 1549 appropriate method for organic manure application for higher sugarcane yield in nigeria ak gana national cereals research institute pmb8, bida, niger state, nigeria. Manure is organic matter, mostly derived from animal feces except in the case of green manure, which can be used as organic fertilizer in agriculture manures contribute to the fertility of the soil by adding organic matter and nutrients , such as nitrogen , that are utilised by bacteria , fungi and other organisms in the soil.
Introduction to organic manure organic manure refers to the manures made from cattle dung, excreta of other animals, rural and urban composts, other animal wastes, and crop residues and last but not the least green manures organic manure is time tested materials for improving the fertility and productivity of soils. In organic production, manure is commonly applied to the field as raw manure (fresh or dried) or composted manure (kuepper, 2003) manure can add important plant nutrients (nitrogen, potassium, and phosphorus, collectively known as npk) to the soil and improve soil quality. When application rates of manure are based on providing adequate nitrogen for crop growth, added phosphorus and potassium levels will often exceed crop need, so manure should not ve the sole n source in an organic system.

Organic farming is an alternative agricultural system which originated early in the 20th century in reaction to rapidly changing farming practices organic farming continues to be developed by various organic agriculture organizations today it relies on fertilizers of organic origin such as compost manure, green manure, and bone meal and places emphasis on techniques such as crop rotation and. In addition, organic n (manure n tied to organic compounds) is more stable than n applied as commercial fertilizer a significant fraction of manure n is stored in an organic form that is slowly released as soils warm and as crops require n commercial fertilizer n is applied as either nitrate or an ammonium (easily converted to nitrate.
