Esperienze di concimazione dei pascoli: risultati consegulti
su terreni trachitici della Sardegna Centro-Occidentale / Bullitta, Pietro; Caredda, Salvatore. - In: STUDI SASSARESI. SEZIONE 3: ANNALI DELLA FACOLTÀ DI AGRARIA DELL'UNIVERSITÀ DI SASSARI. - ISSN 0562-2662. - 25:(1977), pp. 48-59.
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.
