THE IMPACT OF THE GRASSLANDS FERTILIZATION. CASE STUDY –FERTILISATION IN THE LOWER PLAIN OF BANAT ROMANIA

Abstract

In the case of meadows, it is very important to correlate the productive capacity (given by the rating notes) and the correct animal load. Thus, the rating notes indicate the average potential in the current state of exploitation and conservation of soils, potential that can be improved considering the fact that some indicators such as reaction, humus reserve, and porosity are properties that in case of applying measures that widen the area. Manifestation of them as well as of other properties of the environmental factors taken in the calculation of the rating notes. The detailed knowledge of the factors that contribute to the increase or decrease of the production capacity of each part of the territory can ensure for the decision maker an effective tool for choosing working procedures that favor an efficient use of land resources. Nutrient-rich grasslands are dominated by fast-growing species, and nutrient-poor grasslands are dominated by slow-growing conservative species. Traditionally managed grasslands have been widely used in mowing and grazing and have hardly received artificial fertilizers, providing a wide range of habitats that support high biological diversity. But due to the intensive management of pastures, the high intake of nutrients and the increased frequency of defoliation, on the one hand, and the abandonment of marginal pastures, on the other hand, the biodiversity of grasslands has suffered a dramatic decline in recent years. Human activities have significantly altered the availability of nitrogen (N) in most terrestrial ecosystems, with consequences for community composition and ecosystem functioning.
