CHANGES IN MICROORGANISMS ACTIVITY AS A RESULT OF SOIL POLLUTION WITH DOMESTIC WASTE
The number and type of microorganisms in the soil are not always the same, they depend on the chemical composition of the soil, humidity, temperature, pH and other conditions. Soils with low moisture and nutrient content contain up to 105 bacteria per 1 g, and in cultivated soils - 108-109 bacteria. Most bacteria are found in the soil at a depth of 5-15 cm. Microbiological monitoring includes the study of the main groups of agronomically important soil microorganisms involved in the cycle of nitrogen, phosphorus, potassium, carbon and other microelements in the soil layer (0-30 cm) - ammonia esters, oligonitrophils, phosphorus-mobilizing bacteria, actinomycetes. and micromycetes.
