Abstract


One of the most important problems facing sustainable agriculture is the supply of quality fertilizers and the problems encountered in the application of fertilizers. In the last years, while trying to increase the amount of fertilizers obtained by natural methods, On the other hand it has been observed that studies for obtaining different types (solid natural, liquid natural, bio-natural etc.) of fertilizer have continued increasing. The aim of this study is to determine time depend (30 days, 31-60 days) changes of some nutrients and metals in vermiwash obtained from Eisenia fetida fed with fermented natural cow dung. For this purpose, Eisenia fetida were fed with fermented cow dung which obtained from cows grazing in natural habitat and obtained vermiwash were analyzed to determined some macro and micronutrient elements. As a result of the study, while the values of N, K, Ca, Mg, Na, Fe, Ni, Cu, Zn, Hg, Sb in vermiwash decreased at a statistically significant level depending on the time; Co, As, Ag, Cd, Pb, Al, Se, Mo, Li and Be were increased at statistically significant levels.
