To restore a degraded pasture of Brachiaria decumbens, located in São Carlos -SP, southeastem Brazil, under altitude tropical climate, an experiment was carried out to study lhe effects of limestone, buried or not buried in lhe soil, and fertilizer use on mineral content and forage yield, after 3 years of treatment. Limestone and phosphorus were applied once, one month before starting. NK were applied after each cutting, for fertilized plots, four to tive times a year. Experimental design was a random block (100 ml, with 6 replications and 4 treatments. Each block received 4 t/ha of limestone, except lhe control Forage samples were collected 14 cm above soil surface. Instrumental neutron activation analysis (INAA) followed by gamma-ray spectrometry was lhe analytical method used to determine lhe mineral contents. Dry matter yield was affected positively with liming when compared with lhe limestone control, but lhe effect oflimestone use was more pronounced with lhe concomitant use of NK fertilizer. The contents of Ca, Cs, Fe, La, Mg, Rb, Sc, Sm and Th in forage were negatively affected with lhe NK use, perhaps due to a dilution effect, while a reverse were observed for K, CI, perhaps due to input of KCl, besides Br, Mn and Se. It seems that limestone is not a key input to restore degraded tropical pastureland, grown on acid soils, when nitrogen is lacking. INAA allowed lhe monitoring of some not routine elements that mar be under observation to avoid potential plant nutritional disorders in production systems with high limestone and fertilizer use.
