Postponing of the first harvest in semi-natural grasslands: decline in nutrient concentrations?

Popis výsledku v původním jazyce

Postponing of the first harvest until summer is widely incorporated into agri-environmental schemes. In agriculturally improved grasslands a late harvest usually provides forage with much lower N, P and K concentrations than an early harvest. The question is how postponing of first harvest affects nutrient concentrations in biomass if late harvest is applied in semi-natural grasslands for the first time. A rapid seasonal decline of N, P and K concentrations in biomass was recorded in formerly unmanagedBromion but not in formerly grazed Cynosurion and Violion grasslands. Approximately 50% of the grassland biomass consisted of species with persistent leaves in Cynosurion and Violion, while the proportion of these species was very low in Bromion. Total amounts of N, P and K in standing biomass were substantially higher in Bromion than in the other two grasslands in the spring, whereas no differences between sites were observed in the summer. Nutrient dilution and resorption in Bromion ve
