Soil fertility and fertilization as a base of intensification of agricultural production in the Republic of Belarus
The data on dynamics of agrochemical properties changes of arable soils in the Republic of Belarus have been presented: soil acidity, content of mobile forms of phosphorus, potassium and humus. It is noted that the soil acidity state in the republic is practically optimized, the positive dynamics on soil supply by mobile potassium is ensured. Methods of humus regime improvement of arable soils have been shown. Reserves of increase of mineral fertilizer effectiveness are the growth of production volumes and theirs application in complex forms, as well as more intensive microfertilizer use in consideration of biological features of cultivated crops.
