Abstract
The article deals with the ground wild fire impact on physical and chemical and ecological and biological condition of cespitose and podsolic soils on binomial deposits of the Meshcherska province of Gus-Khrustalny district, the Vladimir region under different forest cultures type. In the course of the study, a clear differentiation of changes in the microbiological pool of sod-podzolic soil on bicompartmental deposits under different types of forests was established. The quantitative composition of ammonia factors after exposure to pyrogenic exposure decreased on the sod-podzolic soil of coniferous forests, while the number of photographers, mushrooms, and oligotrophs sharply decreases in the area of pyrogenic exposure in the mixed forest. Within the territory exposed to fire, there is a decrease in the content of organic matter, as well as the content of other biophilic elements. The physical properties of sod-podzolic soil on bicompartmental deposits are also subject to change, in the direction of significant deterioration.
Highlights
The research object in this research is the sod-podzolic soil spread on the territory of Meshchora province, GusKhustalny District, Vladimir Region after direct fireinduced influence of the dead wood caused by unregulated dead wood burning near the village of Shabanovo grass litter burning on the area of 0.01 hectares 52 km to the southwest of Nikulino settlement in Gus-Khrustalny forestry (Meshchora in Gus-Khustalny District (Meshchora Gusevsko-Kolpskaya), the coniferous and broad-leaved forest, the fire on May 2. 2017) grass litter burning on the area of 0,02 hectares
According to a soil properties research after the fire control soil cuts were made on the background and fireinduced soils which allowed to establish type accessory of the explored soils: Near the village of Shabanovo the soil cover is represented by sod-podzolic sandy loam gley soil on binomial deposits, and sod-podzolic sandy loam soil on binomial deposits in Nikulino settlement in GusKhrustalny forestry respectively
The soil cover of the coniferous forest where sod-podzolic sandy loam gley soil on binomial deposits was investigated is characterized by subacidic medium reaction; pH is equal to 5.43 pH units
Summary
The research object in this research is the sod-podzolic soil spread on the territory of Meshchora province, GusKhustalny District, Vladimir Region after direct fireinduced influence of the dead wood caused by unregulated dead wood burning near the village of Shabanovo (the central lake Meshchora, coniferous forest, the fire on April 29. 2017) grass litter burning on the area of 0.01 hectares 52 km to the southwest of Nikulino settlement in Gus-Khrustalny forestry (Meshchora in Gus-Khustalny District (Meshchora Gusevsko-Kolpskaya), the coniferous and broad-leaved (mixed) forest, the fire on May 2. 2017) grass litter burning on the area of 0,02 hectares. The research object in this research is the sod-podzolic soil spread on the territory of Meshchora province, GusKhustalny District, Vladimir Region after direct fireinduced influence of the dead wood caused by unregulated dead wood burning near the village of Shabanovo 2017) grass litter burning on the area of 0.01 hectares 52 km to the southwest of Nikulino settlement in Gus-Khrustalny forestry (Meshchora in Gus-Khustalny District (Meshchora Gusevsko-Kolpskaya), the coniferous and broad-leaved (mixed) forest, the fire on May 2. The research program included determination of the key agrochemical, physical and chemical as well as ecological and biological parameters of the soil according to the standard procedures. Content of the labile phosphorus (P2O5) and potassium (K2O) was determined by Kirsanov's technique in modification of CINAO (Central research Institute of agrochemical service of agriculture) (GOST P 546502011). For the research carrying out 160 soil samples were taken from each the analyzed sites and the composite samples were made for a further research
