Regular soil testing is a critical component of good crop production. It allows you to monitor soil fertility levels, identify potential for nutrient deficiencies, and make fertilizer decisions based on the best possible information.
Jun 6, 2024 · Modern soil tests use a combination of laboratory tests to find the pH, organic matter, and plant nutrient levels of many different minerals in your garden beds. Let’s dig into the details of each type of test, how nutrients affect your crops, and what you can do to fix imbalanced soil.
Sodium is only of secondary importance in the soil test as its uptake by plants is largely dependent on the plant species involved and the potassium status of the soil, rather than the actual level of sodium extractable from the soil.
Nitrate is measured most often in soil tests. Soil test results report NO3- N in lb N/ acre. Nitrate can be leached through the soil and lost to denitrification during periods of soil saturation. Nitrate is also produced by microbial decomposition of organic matter.
For each test, the document describes what is measured, recommends how and when to test, indicates levels at which test results suggest deficiencies or excessive concentrations, and suggests solutions to correct soil imbalances.
Apr 20, 2017 · Thanks to variable-rate technology, growers can even use soil test reports to draw up exactly where they’re going to apply a certain rate of fertilizer or lime. But if someone were to hand you a soil test report, would you be able to read the information and understand what it means?

Mar 16, 2021 · How to Interpret a Soil Test. The colour chart in your soil test kit will help you interpret the results of your tests. There will be separate colour charts for pH, nitrogen, phosphorus, and potassium. A pH test will have a spectrum, usually dark green for alkaline and bright red for acidic, with yellow as neutral in the middle.
