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 ...

The choice of the most optimal composition of aggregates for tillage for work in a certain economy is very difficult from many determined and casual factors. In connection with what, it is suggested to conduct researches with the use of quantificational and quantifier algebra logic. Also we need minimum influences on ecology, being characterized as a predicate of "minimum of expenses on indemn ...

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, ...

In the model experiments we studied the effect of combined action of chemical pollutants (PbO 1,000 mg / kg oil 5% by weight of soil) and microwave radiation (SHF radiation) with a capacity of 450 and 800 W (duration 1 minute) on the enzymatic activity, the number of microorganisms and indicators of phytotoxicity of an ordinary black soil. We found that the combined effect is systemic, rather ...

The analysis of use of glauconitic sand is provided in the article as a potential local fertilizer in the conditions of Kuban. The research of its agrochemical properties showed high value of this substance as fertilizers. In its structure we found macro - and microcells which are necessary for mineral nutrition of plants. Fractionation of phosphorus and potassium in various acids showed their ...
