Positive Effect

The paper evaluates the effectiveness of the aftereffect of the use of biomeliorants (effluent and biocompost) to increase the productivity of soils in degraded reclaimed lands, carried out under the conditions of a lysimetric experiment on a stationary site, when growing annual grasses (vetch-oat mixture). It was experimentally established that effluent and biocompost based on sewage sludge and manure had a positive effect (in the first year of aftereffect) on the productivity and biological activity of soddy-podzolic sandy loam soil of fallow reclaimed agricultural lands.

Positive Effect

The paper presents the results of a lysimetric experiment on sod-podzolic sandy loam soil with the use of effluent from cattle manure, biocompost based on animal husbandry and municipal waste as meliorants. The positive effect of the studied meliorants on the yield of annual grasses was experimentally established. The largest increase in the hay yield of 95.3 % was obtained in the variant with the use of biocompost as a meliorant.

The change in the microbiological activity of sod-podzolic sandy loam soil when using coffee waste and sewage sludge as a fertilizer for oats in comparison with traditional fertilizers is considered. During the study, it was determined that the predominant groups were bacteria and actinomycetes. Bacilli and fungi are few in number. The introduction of sewage sludge and coffee waste into the sod-podzolic sandy loam soil at a dose of 10 t / ha increases the activity of the microflora of the sod-podzolic sandy loam soil, which increases the effective and potential fertility.

Biological activity of the soil is an indicator characterizing the number of organisms living in the soil, and quantitatively evaluating the results of their vital activity. High biological activity is a factor in increasing soil fertility and its phytosanitary state, achieved by creating optimal living conditions for soil microorganisms: providing nutrients, especially organic matter, moisture, heat and soil aeration. In this paper, we assess the effect of hydrogels of different chemical bases on the microbiological activity of sod-podzolic sandy loam soil. The effect of hydrogels on the microbiological activity of sod-podzolic soil was studied in a microfield experiment in a special installation (“dry place”) under conditions of soil drought and field conditions (Menkovsky branch of the FSBIU API, Gatchinsky district, Leningrad region). The experience was laid with two types of hydrogels (potassium and sodium base) with a single dose (40 g/m2). In the experiment, the indicators of soil biological activity were compared in the following variants: soil - control with the addition of 90 kg ha-1 NPK in the form of an azofoska, hydrogel introduced to a depth of 10–12 cm + N90 P90 K90, hydrogel introduced to a depth of 20–22 cm + N90P90K90. Samples of sod-podzolic sandy loam soil were taken from depths (10–12 cm and 20–22 cm) at the beginning and at the end of the growing season. In the course of the studies, it was found that when the hydrogel is introduced, both in the upper root-inhabited soil layer and in the 20–22 cm layer, favorable conditions are created for the microbiological activity of sod-podzolic sandy loam soil. It has been established that the chemical basis of the hydrogel does not inhibit the activity of the microbial community.
