Description
On 42 sites in 10 districts of the Carpathian region of the CSSR, relationships were examined between grassland production and regional, climatic (precipitation, temperature, solar radiation), and soil conditions (soil type, pH, S, 'r, V, C0., nutrients, and clay fraction). To this, five variants of fertilization were used (0; PK; 120 kg N/ha + PK, 240 kg N/ha + PK; 480 kg N/ha + PK). None of the natural ecofactors is generally characteristic enough for determining an optimal production. But the nutrition and the utilization of grass stands are important under each condition. Therefore, a system of differentiated grassland management is proposed with 5 levels of intensity for large farms. Besides fertilization, utilization and complex ecoanalysis in this system, also the organizational and economic criteria are considered.

The evaluation of relationships between ecological factors and production on permanent grassland
On 42 sites in 10 districts of the Carpathian region of the CSSR, relationships were examined between grassland production and regional, climatic (precipitation, temperature, solar radiation), and soil conditions (soil type, pH, S, 'r, V, C0., nutrients, and clay fraction).

None of the natural ecofactors is generally characteristic enough for determining an optimal production. But the nutrition and the utilization of grass stands are important under each condition. Therefore, a system of differentiated grassland management is proposed with 5 levels of intensity for large farms. Besides fertilization, utilization and complex ecoanalysis in this system, also the organizational and economic criteria are considered.
