Understanding the contribution of humalite for soil health and crop production

Humalite is a naturally occurring organic substance containing high concentrations of humic acid. Humic-based substances are well known for improving the physical, chemical, and biological properties of the soil. Therefore, humalite may be a cost-effective and environmentally friendly soil amendment with a wide variety of end uses. Large deposits of humalite were found in Southern Central Alberta that may have great potential to commercialize for improving soil health and sustainable agricultural production. We partner with the Prairie Mines & Royalty ULC to evaluate potential benefits of humalite for 1) improving soil nutrient availability and plant nutrient uptake, 2) improving soil microbial population and diversity, 3) improving plant growth, yield, and nutritional quality, 4) improving symbiotic nitrogen fixation in legume crops, and 5) alleviating drought stress on crop production. We expect to develop humalite-based marketable products for the diverse agricultural industries, which are economical and environmentally friendly to the end users.
