WebSoil acidity is a condition in which the soil pH is lower than a neutral pH (less than 7). Soil pH is a measure of the hydrogen (H+) ion concentration expressed as the negative common … WebDec 23, 2024 · The important point to note is that soil Colwell P values needed for optimum crop production increase with increasing PBI values. This is because: Low PBI soils only bind small amounts of P, leaving more of the fertiliser-applied P available for plant uptake. High PBI soils bind higher amounts of P, making more of it unavailable for plant use.
