When it comes to growing produce, the quality of soil is extremely important to our organic farmers. There are many factors that go into soil quality, which ultimately determines plant productivity and nutrient value. Soil tests are done annually at our farms in order to ensure proper acidity level and to determine which organic fertilizers are necessary to keep crops well nourished.
The heart of organic farming involves crop rotations to keep the soil well balanced. Oftentimes it will take 2 to 3 years for a crop to be able to cycle back around to the same planting location. This is because each crop is partial to certain nutrients in the soil and will absorb large quantities while in place. These nutrients must be re-established in order to host that crop again. Crop rotation systems also help control pests and erosion on the farm.
A 30-year side-by-side comparison study by the Rodale Institute found that industrial farming methods maintain soil health with chemical fertilizers – which over time destroys microbial life and weakens soil integrity. The same study showed that organic farming methods improved the quality of soil.
Poor soil can contribute to blight, poor taste, erosion, low microorganism counts and low productivity. Healthy soil is dark and porous. Next time you take a farm tour, take a moment to dig up some soil! It is a great way to determine the quality of produce.
Fun Fact: One Tablespoon of soil has more organisms inside of it than there are people on earth!
