Nutrient requirements for intensive forage crop production are similar to those for soybean and corn. On Florida's acid, infetile mineral soils, judicious liming and micronutrient fertilization should precede application of macronutrients because of the potential for Al toxicity, Mg deficiency, micronutrient deficiencies, and losses of macronutrients through leaching. Forage production and N content of white clover-grasses without fertilizer N have been comparable to those from perennial grasses fertilized with 224 to 448 kg on N/ha annually. Beef production from legume-grass pastures generally exceeded that from grass pastures at N rates through 134 kg/ha/year. The potential for substitution of symbiotically-fixed N by legumes for fertilizer N was emphasized. Lime and fertilizer costs per kg of beef, at current prices, are $0.51 for the grass and for the legume-grass pasture, less than $0.18. For successful production of legume-grass pastures, management must be more precise and consistent than for grass pasture. Soil acidity must be corrected by liming, micronutrient levels must be maintained, and P and K must be applied at least annually. |
