Caractéristiques
Significance of use
The soil pH range from pH 5.5 to 7.5 is inclusive of most plants; however, some species prefer a more acidic or alkaline environment. Nevertheless, every plant thrives within a particular pH range. pH strongly influences the availability of nutrients and the presence of microorganisms and plants in the soil. The three macronutrients that are most needed by plants are nitrogen (N), phosphorus (P), and potassium (K). Other elements, the so-called microelements, are generally present in sufficient quantities in the soil as plants need them only in smaller doses.
