Abstract

• rganic fertiliers prepared from organic astes can reduce cost in agricultural sectors and increase soil fertility. This research or concerns ith studies for the preparation of organic fertiliers from rice stra, chicen manure and neem leaves, its application for crop cultivation and studies the effect of fertilier on soil fertility. Rice stra from farmer field, neem leaves from un Chan illage in Taungdingyi Tonship and chicen manure from Pyay Tonship ere collected. The organic fertiliers ere prepared by five different eight ratios g g g, rice stra, chicen manure, neem leaves for organic fertilier , g g g for , g g g for , g g g for , and g g g for . These different fertiliers ere prepared by compost heap method. The physicochemical properties and, content of macronutrients and micronutrients ere determined by EDR, and other modern and conventional methods. It as found that contains ., .P, ., ., .P, ., ., .P, ., ., .P, ., . , .P, ..rom EDR result, the amount of Ca, and i are higher than other elements in five different ratios of organic fertiliers. It as found that, these organic fertiliers contain Ca, Mg, n, Cu, Mn and e by measurement. ccording to these results, it as found that as rich in macronutrients. o as chosen to use for crop cultivation and improving the soil fertility. The rice stra based organic fertiliers should be used as effective fertilier for agricultural section and for reducing the use of chemical fertilier hich can damage the soil fertility.
