Comparison of vermiwash and vermicompost tea properties produced from diferent organic beds under greenhouse conditions

Purpose Using diferent organic beds to produce vermicompost may infuence on quality of vermicompost and its derived productions. Methods A greenhouse experiment was conducted to compare the properties of vermicompost, vermiwash and vermicompost tea obtained from three types of organic beds consisted of cow manure, leaf meal and a combination of cow manure and leaf meal (۱:۱ w/w). Results Cow manure vermicompost had more desirable efect on many measured traits toward leaf meal and combination of leaf meal and cow manure vermicomposts. Vermicompost tea obtained from three vermicompost types was richer in terms of macro and micro nutrients, C/N, percent of organic matter and organic carbon toward the vermiwash produced from the same vermicompost. Vermiwash and vermicompost tea produced from cow manure vermicompost were at frst order in majority of measured traits toward others. Conclusions Generally vermicompost which was richer in nutrient concentrations afected intensively quality of vermiwash and vermicompost tea produced from it.
