The main indicators of efficiency of a cultivation machine are the following: productiveness and fuel consumption, which depend on complexity of work, operating depth and structure of the machine (type of the tractor and plough). The optimal structure of cultivation aggregate for the needs of each exact farm is complicated to do due to different determined and stochastic factors. In this case, ...

The problem of environmental safety of agricultural products and agro-technical measures is very urgent now. Various agrochemicals are widely used in agricultural production: plant protection preparations, fertilizers, stimulants and plant growth regulators, etc. One possible solution of this problem may be a partial replacement of mineral fertilizers by bacterial ones. The aim of our research ...

We have investigated the influence of nickel oxide in the amount 100, 1000 mg/kg of the soil (1, 10 MPC), combined with the influence of variation magnetic field with induction of 50, 100 and 650 μT power frequency of 50 Hz on the enzyme activity and phytotoxity of the southern chernozem. We have established significant reduction of enzyme activity of catalase and length of roots after the inf ...
