The Study the Compost Mass Moisture and the Degree of Straw Crushing Effect on Compost Temperature in a Multifactorial Experiment

The composting of crop and livestock waste multifactorial experiment was conducted in order to determine the main controlled factors impact such as humidity and straw crushing degree on the composting process. The experiment allows to measure the values of controlled factors in the composting process, at which the maximum compost temperature was reached. The influence degree of two main controlled factors - the humidity content of the material $X_{1}(W)$ and the straw length $X_{3}$ (n) on the composting was determined, with an optimal of carbon/nitrogen ratio $X_{2}(C: N)-40.1$. The composting process that was influenced by controlled factor, was studied and the reliability coefficient of approximation $R^{2}$ for each controlled factor was determined.
