Grassland needs a good rainfall distribution for high yield potentials.
In addition to nitrogen, an adequate fertilization with sulphur is necessary at high yield levels.
Phosphorus and potassium fertilization is based on withdrawal by the harvests.
Organic fertilization, biological nitrogen fixation, and organic matter provide significant amounts of nitrogen.
The amount and distribution of rainfall is essential for grassland. For good growth, grassland needs a minimum of 800 mm annual precipitation. On the other hand, too much and too frequent rain impedes fodder conservation.
The plants in grassland should have high protein and energy contents, to ensure a good nutrition for the animals. The protein and energy content is particularly high in clover and grasses in young development stages. Therefore, the ideal timing for the cuts compromise between nutritional value and yield (biomass). In addition to the optimum timing of the cuts the following factors are important: correct fertilization, regular reseeding, harvesting technologies should all be considered as well as avoiding soil compaction and reducing rodent activity is important to achieve high yields.
