Applying phosphorus through drip irrigation systems

Abstract

The disadvantages of clogging drip lines and assumed lack of movement have prevented the application of orthophosphate through drip irrigation systems. Orthosphosphoric acid can be applied without these disadvantages when extreme care is used. Organic phosphates such as glycerophosphate will move farther in soils, are easily applied through the drip system without clogging, and P is readily used by plants.
