Tests for pH, Nitrogen, Phosphorous and Potash
Plants need food (nutrients) for healthy growth. Nitrogen, Phosphorus and Potash play a vital role in plant growth just vitamins, minerals, carbohydrates and protein do in our health.
Soil should be tested throughout the growing season but it is especially important to test before planting in spring and when preparing the beds in fall. And of course, if your plants aren't doing well, a soil test will help.
