For every 1,000 square feet, use 100 pounds for severely deficient soil, 50 pounds for moderately deficient soil and 25 pounds for slightly deficient soil. The pH value of a soil is influenced by the kinds of parent materials from which the soil was formed. Adding green manure residues to soils can increase soil mineralization rates of phosphorus, but low concentrations in residues often won’t meet crop demands.

Therefore, the effects of having a phosphorus deficiency will end up diminishing a crops growth. Use a starter fertilizer when planting in cold, wet soils — particularly when soil tests are not high.

Attached you can see my soil sample results just received back from Texas A&M. P activators can increase the availability of this P to plants by accelerating its transformation into soluble P fractions. Phosphorous is one of the 3 key nutrients required for healthy plant growth. Excessive soil phosphorus reduces the plant’s ability to take up required mi-cronutrients, particularly iron and zinc, even when soil tests show there are adequate amounts of those nutrients in the soil.
