ABSTRACT:
Concentrated phosphorous fertilizers are disclosed that comprise a buffered composition of a phosphorous-containing acid or salt thereof. The concentrated phosphorus fertilizers can be diluted with water of pH ranging from about 6.5 to about 8.5 at ratios of concentrate to water at about 1:40 to about 1:600 to result in a fertilizer having a pH in the range acceptable for foliar uptake of phosphorus. Methods of supplying phosphorus to plants are also disclosed where the concentrated phosphorus fertilizers are delivered to plants and then sufficient water is applied to achieve a pH suitable for phosphorus uptake by the plant.
