Preparing the Soil for a Vegetable Garden
These beets need plenty of nutrients
in the form of fertilizer.
The necessary nutrient levels are relative to the soil type and the crop being grown. Although different vegetable plants have varying requirements, the soil test institution calculates an optimum average for fertilizer and lime recommendations.
The results of the soil test will indicate the pH (acid-alkaline balance) of the soil as well as the nitrogen content, phosphorus content, and potassium content. The pH is measured on a scale of 1 (most acid or sour) to 14 (most alkaline or sweet), with 7 representing neutral. Most vegetable plants produce best in a soil that has a pH between 5.5 and 7.5.
The pH number is important because it affects the availability of most of the essential nutrients in the soil. The soil lab will consider the type of soil you have, the pH level, and the crops you intend to produce and make a recommendation for pH adjustment.
Phosphorus (P) and potassium (K) levels will be indicated by a "Low," "Medium," or "High" level. High is the desired level for vegetable gardens for both nutrients. If your test results show other than High, a recommendation of type and amount of fertilizer will be made.
Although nitrogen (N) is also needed in large amounts by plants, the soil nitrates level is not usually routinely tested because rainfall leaches nitrates from the soil, which easily results in low levels. Additional nitrogen through the use of a complete fertilizer is almost always recommended.
Tests for other elements are available on request but are needed only under special circumstances. To learn how to read a soil test report, go to the next page.
