  After the millennium the utilization of the Hungarian grasslands is particularly important. We considered the priorities of the Darányi Ignácz Plan where the efficient utilization of the agricultural areas - including grasslands, pastures- by increasing the number of ruminants is the part of the rural strategy. The effective utilization of the by-product, the manure in croplands or pastures is particularly important, taking the increasing fertilizer prices within the continuously opening price scissor of the industrial-agricultural products into account. The patent of the Karcag Research Institute of CAAES RISF UD, the TERRASOL compost is a good alternative for farmers. We have already published the primary results of our grassland fertilization experiment, where we investigated the utilization of different compost doses and evaluated these from economic point of view. In this paper we examined the changes of the properties of the soil in the different treatments. We visualized our results by using GIS methods. We measured the moisture content, the penetration resistance and the CO2 emission of the soil of the four treatments. We determined that the 20 t/ha of compost dose is considered as sufficient to improve the investigated properties of the grassland soils under the droughty conditions of 2012.
