Abstract
In the biennum 1972-'74, a factorial trial on N, P, K, fertilization was carried aut on trachytic permanent pastures of Central-western Sardinia. Nitrogen, at the dose of 100 kg/ha, brought about greatest production increases of dry matter and U.F.. Phosphorus - still working beneficially on the production, even if in a slighter manner - has its macroscopic effects on plant population, with a remarkable leguminosae increase. In the absolute, the best results are attained by binary N + P fertlization (about 50 kg/ha of dry matter). K shows to have no effect.| File | Dimensione | Formato | |
