A grazing experiment was conducted on an Oxisol testing five degraded tropical grasses renocated with two levels two levels of fertilizer with the objective to study seasonal changes in plant nutrient contents and soil fertility. Total dry matter availability, green and dead matter availabilities, nutrient concentration in leaf tissue and soil fertility were the parameters measured. Availability of forage and leaf nutrients was significantly dependent on seasonal changes with green matter on offer decreasing over years. Soil fertility increased after renovation and declined thereafter. Soil available-P decreased it was related to sustainability of green matter on offer. Soil organic matter mineralization was the greater N source to plants. Lack of regular N supply plus soil-P decline would be responsible for decreasing of stocking rate and animal production. |
