The Author presents a way of assessment of forecast effect of land parcel consolidation of agricultural estates areas due to decrease of number of land parcels of grassland. The effect was developed on the basis of research of both calculable effect of land parcel consolidation of agricultural estates due to decrease of number land parcels of grassland as well as the cost related to land configuration of these land parcels. As a result of analysis of this mathematical formula it was identified that the mentioned effect is a function of increase (or decrease) of number of land parcels of grassland with both one and two side access to roads (this increase or decrease of number of land parcels is a result of land parcel consolidation of agricultural estates within one cadastral district). This effect might be used as one of possible factors that can qualify a cadastral district for process of land parcel consolidation.
