The first 2 years of testing serve to gain an overview of the methodological process so that individual variants can be introduced to practical organic farms in the third year. These serve to evaluate the location factor and to cover several regions in the Alpine region of Austria. The variants are fertilized with different fertilizers and used as a 3-cut meadow. Fertilization is carried out in all commercial fertilizer systems (manure, rotted manure and manure compost) according to the quantities produced for a given livestock population. In the first, fourth and seventh years of the test, soil samples are taken which are used to assess the condition of the soil. A qualitative and quantitative analysis of the cuttings is carried out from each plot at each harvest date. In the years in which the soil samples are taken, the plant population is also assessed.

Aims of the investigation:

• Document changes in the composition of the plant population

• Document changes in the soil

• Evaluate the stability of the grassland scar

• Evaluate the effect of stone powder in manure on soil and plants
