The thermal behavior and non-isothermal kinetics of thermal decomposition of three different kinds of composting of the USR like: stack with drilled PVC tubes (ST), revolved stack (SR) and stack with material of structure ...
Effect of gamma irradiation on the nutritional quality of Agaricus bisporus strains cultivated in different composts
(Acad Brasileira de Ciências, 2014-06-01)
The effect of irradiation doses (0, 125, 250 and 500 Gy) on the nutritional quality of A. bisporus mushrooms (strains ABI-07/06, ABI-05/03 and PB-1) cultivated in composts based on oat straw (Avena sativa) and brachiaria ...
Phytotoxicity and cytogenotoxicity of composted tannery sludge
(2020-09-01)
Tannery sludge (TS) contains high levels of organic matter and chemical elements, mainly chromium (Cr). This can increase its toxicity, rendering it unsuitable for application to soil. However, composting has been proposed ...
