Nitrogen is a key element in proteins, serves as a food
source for microorganisms in the compost pile, and
fosters green growth. Phosphorus gives plants energy and
is necessary for the growth of Jowers and seeds.
Potassium aids in protein synthesis and the translocation
of carbohydrates to build strong stems and roots which
are the controlling part of the plant. Plants also need a
good supply of organic matter to give them additional
nitrogen, phosphorus, sulphur, copper, zinc, boron, and
molybdenum, along with eight other nutrients. Only
under ideal conditions do native soil minerals provide
these nutrients naturally. Plants need a full meal of
nutrients, and as good stewards of the soil we are
responsible for providing them.
pH
A pH reading tells you the relative acidity or alkalinity
of the soil water, generally called the soil solution.
Nutrient availability for vegetable plants, soil microbial
activity, and soil structure are all a5ected by pH. Most
vegetables grow best in a slightly acidic soil with a pH of
6.8. A range of 6.0 to 7.0 is fine for most crops.
More important than the actual pH reading is the
quality of the pH. This is determined by testing for the
amount of plant-available potassium, magnesium,
calcium, and sodium in your soil. Only a professional
