Influence of manure with activators of organic matter on physical properties of soil

Abstract

Soil decarbonisation is a long-term problem in almost all agriculturally important areas and, of course, in the Czech Republic also. This is due to decrease in livestock production and due to associated decrease in organic fertilizer production. Application of manure is one of the best ways to change this condition. Manure can be added by biological activators of organic matter. The main aim of the paper is to authenticate the benefit of modified farmyard manure and of substances for soil amendment on the improvement of physical, physical-chemical and biological soil properties, on organic matter fixation, on improvement of water infiltration and retention, on reduction of soil erosion susceptibility, and on reduction of soil tillage energy demand. In this respect, multi-annual field experiments have been established at locality Lázně Bělohrad in the North of Bohemia. Semi-operational experiment consists of six variants and it was established in 2014. As the biological transformation's activator, PRP sol agent has been used. In order to verify the effect, soil infiltration abilities have been measured using a ring infiltrometer with a diameter of 0.15 meters. Cone index has been another measured item provided by the registration penetrometer. Soil physical properties have been evaluated employing Kopecky's cylinders and subsequently analysed in the laboratories of the CULS Prague. Improvements have been observed in decrease in the bulk density, increase in porosity, decrease in the cone index and increase in saturated hydraulic conductivity.
