Soil nutrition/pH is probably the easiest soil attribute to manipulate yet it is often overlooked. Soil that has previously been in forest production can be very acidic. While this acidity is not a direct nutrient it does directly affect the uptake of nutrients to the plant. Different plants have optimal ranges in soil pH, however, most need a soil pH between 6.2-7.0 on a 0-14 scale. The lower numbers indicate higher acidity and higher numbers being basic or less acidic.
