The climatic conditions of the Troyan Mountain are favourable for large-scale production of plum fruit. The soils are Eutric Planosols with low organic matter content and hence low nitrogen content. The usually applied agrotechnology involves three fertilizations with nitrogen per year and a full organic+mineral fertilization once every three years. Because of the fact that the regions are water supplying, it is very important to avoid nitrate contamination of soil and water. The natural conditions are favourable for sheep breeding. The sheep manuring in this region is considered as an economically feasible and ecologically appropriate alternative of the mineral fertilization. The objective of study is to establish the changes of soil properties as a result of single summer and autumn manuring during sheep flock resting in plum orchards and to choose the appropriate application method for improving soil productivity potential.
