After a description of surface relief, soil profile, grassland production and the interrelation between these factors, the practice of land levelling in the areas examined was analysed. Since levelling changes the microrelief, attention was given to the measurement and description of the relevant characteristics of this relief.
A primary purpose of this study was to find the effect of. levelling on the quality and production of grassland.
The increase in yearly production was found to be about 20 to 30%. of the total production of the best grasslands, where total production was about 10 tons dry matter per ha each year. A substantial improvement in quality was measured as well.
Since the results of this investigation could also be used in planning land levelling, special attention was given to the principles of planning this type of land preparation.
