Phosphate (P₂O₅)
Function in the plant
Phosphate promotes root development and thus the growth of the crop and is necessary for outgrowth. Especially in spring, when the roots have to develop, a good phosphate supply is of great importance, as a shortage results in a slow start to growth; in turn, a shortage translates into reduced yields.
Target range in the soil
For each soil type, a target range has been established within which the P-Al figure should be situated to ensure optimal crop growth.
