Unlock the Potential of Your Soil with a Soil Test

People often ask me if an organic grower can do anything about micronutrient deficiencies in the soil. It is a good question, as we are relying on whole foods for our whole health, and obviously micronutrients are as vital for human health as they are for plant vigor.

The answer is that you absolutely can amend your soil with elemental micronutrients as long as your soil test shows the need for it and the source of the nutrient is non-synthetic and approved by your organic certification agency. I think that there is validity in this system. Organic growers understand that micronutrients are essential for a successful harvest, but I respect that the system asks first for proof of need. The beauty in organic farming is being more in touch with the basic health of your soil. There is no given formula for a specific crop or a specific soil type. A recent soil test that shows a need for micronutrients necessitates continual monitoring versus fertilizing out of habit.

We take a substantial number of soil tests at Standard Process. You get the best results if you consistently take samples at the same time of year, so we always pull our samples in the fall (the ground is firmer and we have a little more time!). Personally, I use the Standard Process soil sample results as a guide to let me know if our agronomic practices are self-sustaining. The productivity at the Standard Process Farm is very high and we continually demand a lot out of the soil. Soil tests reflect a very vibrant soil at Standard Process, and trends in these soil samples help to ensure that we will maintain high productivity. For example, organic matter results reflect whether the cover crops we are utilizing are maintaining or growing our organic matter. Nutrient and micronutrient trends illustrate if the fertility program we are using is building versus depleting the soil in any particular area.

A soil test is a good idea for anyone who wants to maintain a lawn, gardenÐeven the Standard Process Farm. To start, it is important to take the test at the correct depth and it is critical to use a soil probe. You may find a few surprising results in your soil test that could really help you better your lawn or garden. For example, if you have healthy levels of every nutrient and micronutrient, but your test shows a lack of manganese, a simple application of manganese could greatly unlock the potential of your soil. Find an extension or horticultural agent in your local area to help you test your soil correctly and provide you with contact information for a soil lab.

Whether you are a traditional home gardener or a large organic farming operation, you can benefit from the picture that a soil sample paints.
