Traditional soluble salt fertilizers are very unstable and can be leached out of the root zone or become complexed by soil minerals very quickly. This is especially the case for anions such as nitrogen, phosphorus, and sulfur, as well as for trace minerals. Stable humic substances such as those found in HumaCarb™ are proven to hold nutrients in the root zone longer and reduce potential fertilizer loss, as well as enhance soil microbiology. HumaCarb™ can be tank mixed with nutrient applications to improve fertilizer use efficiency and crop performance. It cannot be mixed with urea or ammonium thiosulfate. Always conduct a jar test before applying.
