After the millennium the utilization of the Hungarian grasslands is particularly important. Weconsidered the efficient utilization of the agricultural areas - including grasslands, pastures- byincreasing 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 fertilizerprices 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 goodalternative fertilizer for farmers. We have already published the primary results of our grasslandfertilization experiment, where we investigated the utilization of different compost doses and evaluatedthese from economic point of view. In this paper we examined the changes of the properties of the soil inthe different treatments. We visualized our results by using GIS methods. We measured the moisturecontent, the penetration resistance and the CO 2 emission of the soil of the four treatments. We determinedthat the 20 t/ha of compost dose was considered sufficient to improve the investigated properties of thegrassland soils under the droughty conditions of 2012.
