Abstract:

Agricultural land in the Czech Republic threatened by a combination of water erosion, technogenic compaction and low level of soil carbon. The low levels of carbon in the soil interrelate also with the other threats mentioned. Application of organic matter into soil is one of the ways how to rectify this unfavourable condition. All of its forms can be supplemented by biological transformation’s activators. The aim of this paper was to verify the effect of organic fertilizer with a conditioning activator added, i.e. manure from deep-litter housing of dairy cows with PRP Fix added, and the effect of an activator conditioning soil, i.e. PRP Sol, on the change of soil physical properties, i.e soil bulk density, infiltration ability, cone index. In this respect, field trial was established at locality Lázně Bělohrad. Soil infiltration capabilities were measured using a ring infiltrometer with a diameter of 0.15 meters. Cone index was another measured item provided by the registration penetrometer. Bulk densities of each trial variant were evaluated using Kopecky’s cylinder. Concerning saturated hydraulic conductivity, all the variants treated with manure demonstrated its increase, namely with soil activators applied as well. Favourable effect on soil bulk density values could have been also observed. The change was often below the level of statistical significance. This could have been caused by a short only time of activator’s activity. It can be assumed that the effect is going to be gradual and the verification should be carried out also in following trial years.
