The “standard soil analysis package” measures soil acidity (pH) and estimates the plant-available concentrations of the major nutrients, phosphorus (P), potassium (K) and magnesium (Mg), in the soil.
4 Ιαν 2023 · A soil pH-nutrient availability diagram was developed for the humid regions of the USA that showed the availability of some major and minor nutrients at a pH ranging from 4 to 10 (Pettinger 1936; Truog 1946b). It became known as the “Truog diagram” and it has guided soil fertility research and has been widely reproduced in scientific and ...

The pH of the soil in relation to the availability of plant nutrients has been an important research topic in soil fertility and plant nutrition. In the 1930 and 1940 s, a diagram was proposed that showed how the availability of major and minor nutrients was afected by the pH.
4 Ιαν 2023 · Diagram illustrating the trend of soil reaction (pH) to the availability of plant nutrients, from “A useful chart for teaching the relation of soil reaction to the availability of plant...
7 Μαρ 2023 · In an accompanying paper (Hartemink and Barrow 2023), we discussed a conceptual soil pH-nutrient availability diagram that purported to show how the availability of major and minor nutrients was affected by the pH. The diagram has been published in textbooks and soil extension material and continues to be used as a teaching tool.
Assessing present- and reserved-nutrient status of the soil, understanding its nutrient-release and nutrient-holding capacity, and knowing the plant and environmental factors
