This lack of fertilizer response is most likely due to the recycling of nutrients occurring on the pasture and a reflection of Kempfer's history of fertilization. The results of this study agree with our limpograss fertilizer studies conducted in south Florida. More studies are being conducted to evaluate the fertilizer requirements of limpograss on different soil types to insure that the results are similar. Until IFAS completes all these studies and reviews and revises the fertilizer requirements of limpograss, it is advisable to apply a maintenance level of phosphorus and potassium to limpograss. Approximately 20 pounds of phosphate and 40 pounds of potash should be applied per acre annually in early spring.
Limestone is also important for limpograss production.
Our studies have shown that the soil pH needs to be 5.0 or higher. Our results indicated that when the soil pH was increased from 4.5 to 5.0 with the addition of one ton per acre of limestone, yields increased 0.8 tons per acre. When considering lime application, one should strongly consider dolomitic limestone since it not only raises soil pH and provides calcium but also supplies needed magnesium for the plant.
