HUMI-SOURCE™ products are liquid potassium humates extracted from North Dakota’s world renowned leonardite ore. HUMI-SOURCE™ provides a soluble source of humus that improves the organic matter fraction of the soil. Crop production is increased as the efficiency of N-P-K fertilizers is improved and micronutrients found in the soil are activated for plant use.

HUMI-SOURCE™ is an excellent additive for starter fertilizers, particularly when micronutrients such as zinc, manganese and iron are being applied. Tests show that plants grow faster and more robustly where HUMI-SOURCE is used on sodic or calcareous soils or on soils low in organic matter.

HUMI-SOURCE™ products can be used in irrigation systems or applied with crop sprayers. The application of HUMI-SOURCE™ humic acid supplements result in healthier crops and greater yields.
