Description
Little research has been done to determine the effect of fertilization on irrigated pastures in Santa Cruz (South Patagonia). The objective of the present study was to estimate the effects of NPS fertilizing effects on forage yield and quality. The trial was set up in 1994 on a Borolic Haplargid soil characterized by low N content (0.00875% total N), low P availability (9 ppm Olsen) and medium alcalinity (pH 8.4). Pasture was dominated by tall fescue (95%) with 5% of alfalfa. A Complete Radom Design was used and N-P2O5-S nutrients were applied at rates of 120-100-50 kg.ha-1. Monthly mowing began in November and finished in March 1995. DM yield, CP and IVDMD were determined. N-fertilization highly increased DM yield. PSfertilization affected botanical composition by increasing alfalfa proportion, and this determined PS treatment to have the highest BP content. Fertilization had no apparent effect on IVDMD.
