In a field experiment it has been found that the biological activity of the soil under agriculture, as an indicator of its ecological health, depends much on the weather. In extreme excessive humidity and temperatures exceeding average 2–5°C for periods compared to the same hot, but arid periods the number of total microbial mass increases in soil, synthetic processes are intensified and carbon emissions are activated. Accordingly, the yield of green mass of corn is raised, though grain yield reduces significantly. In the year of high temperature and lack of providing moisture harvest of green mass reduces significantly, but the crop is formed at the level of optimal under the weather conditions of the year, due to relative drought-resistance of the crop.
