Objectives of the study were as follows: (1) Compare magnesium- ammonium-phosphate (MAP) with a standard granular fertilizer such as triple superphosphate (TSP) for their plant feeding properties; (2) Evaluate both materials over a wide range of treatment rates; (3) Observe the capacity of these materials to stimulate legume seedlings in an established grass sod; (4) Investigate nutrient uptake by the growing crop as measured by plant tissue analyses; and, (5) Examine changes in soil fertility levels as affected by rate and source of phosphorus carrier.
