introduction due to the development of sustainable agriculture and the reduction of utilizing chemical fertilizers, it is essential to use organic fertilizer. organic matter is vital to soil fertility and its productivity. to maintain the level of fertility and the strength of soil, organic matter levels should be maintained at an appropriate level. unfortunately, the level of organic matter in...

qualitative and quantitative analyses of phyto- and zooplankton, and growth performance of cyprinus carpio linnaeus were done in earthen vats receiving compost, diammonium phosphate and vermicompost as direct application fertilizer were conducted. significant differences were observed in the diversity and abundance of plankton in response to fertilization. the highest production of fish was obt...

Aluminum toxicity is a major limitation to leguminous crop production in acidic soils but mineral and organic fertilizer applications could ameliorate the condition. Thus, focus of this study was evaluate influence manures on post-harvest soil fertility quality, yield agronomic efficiencies soybean (Glycine max). The had six treatments: poultry manures, rabbit pig sheep cattle single super phos...

a field study was conducted in qaen region using complete randomized blocks with three replications to study the effect of organic manure, zinc and boron on yield and yield components of millet and grain chemical composition. the treatments included factorial arrangement of municipal solid waste compost and cow manure (each at 25 ton ha-1), zn (0, 50 kg ha-1) and b (0, 10 kg ha-1) by using thei...

Improving the sustainability of agriculture has become crucial to deal with tomorrow’s challenges such as supplying food to a continuously growing world population while mitigating its environmental impacts (e.g. climate changes). Recycling organic wastes to substitute chemical fertilizers for various organic ones (e.g. sewage sludge, household refuses, plant residues, livestock manures, agro-f...
