From AEA. Soluble nutrient fertilizers are very unstable and can be leached out of the root zone or become complexed by soil minerals quickly, becoming unavailable to plants. This is especially the case for anions such as nitrogen, phosphorus and sulfur, as well as for trace minerals, which are easily complexed. Stable humic substances are well documented to stabilize nutrients in the root zone, and reduce potential fertilizer loss, as well as enhance soil microbiology. Tank mix with nutrient applications at a 3% solution.
