The Effect of Soil pH on Nutrient Availability

Daniel CooperNutrition

By Chris Oswalt Soil pH influences nutrient availability. This article considers the specific fate of nitrogen, phosphorus and potassium in soils with elevated pH values. The discussion also assumes that these effects would be similar to conditions in the wetted zone where micro-sprinkler irrigation has raised soil pH. NITROGEN Soil pH can affect several reactions involving nitrogen in the soil …
