Grasslands represent a land-use which is effective and has great economical importance in the European agriculture. Grasslands represent an important and effective source of energy and proteins to ruminants, and combine high yield stability and draught resistance with low tillage operations and pesticide use and thus leading to good environmental conditions. Furthermore, good management practice in grasslands provides high potential of carbon sequestration in soils, resulting in climate change mitigation. The field experiment were carried out on a field study was conducted in the central part of Kosovo, respectively Lipjani location 15 km near the capitol city of Prishtina. The plot sizes were 81. 5x 8m per plot or 12 m2. The fertilization also was used in quantity 80 kg N ha -1. In experiment was including four treatments: C- Control (normal cutting without harrowing); Cutting regime include; A-One week early without harrowing, B- One week later without harrowing and H-With harrowing. The samples were decomposed with concentrated HNO3 at 250°C in Ultra-Clave from Milestone (Milestone microwave Ultra clave III). The samples were diluted to 10 % concentrated HNO3 before analysis. The results were obtained in our study demonstrated that substantial differences in mineral composition exist in grasslands. The four treatments had considerable variation in mineral composition. The Aluminum (Al) and Calcium (Ca) content ranged from 0. 36 to 0. 19 and 5. 07 to 7. 31 g kg-1 respectively.
Key words; Grassland, treatments, harrowing, mineral composition.
