Objective  The purpose of this research project was to evaluate how humic acids stimulate microbial activity and initiation of the rhizophagy cycle (in which plants cultivate microbes on their roots and then absorb them to extract their nutrients). Huma® Huma Pro®, a liquid 6% humic acid product, was used as the humic acid biostimulant source. 

Background Humic substances have been shown to improve crop yield. Solid and liquid forms of humic substances with high levels of organic acids can be produced by incorporating Micro Carbon Technology®. Some are suitable for conventional and others for organic farming. Huma® OM Liquid HA 16, OMRI-Listed for organic farming, is a liquid form of

Background Scientific research shows that humic and fulvic acids are biostimulants—enhancing nutrient availability and uptake, improving plant root growth and mass, and impacting both crop yield and quality. Objective The focus of this study was to assess the effect of pre-plant application of a raw humic product on potato yield. Materials & Methods One week

Introduction  In this study (originally published in Frontiers in Plant Science, May 2021, Vol. 12:660224), the biostimulant properties of a sedimentary shale ore-extracted humic acid (HA) were tested on Micro Tom tomato plants under increasing nutritional stress  Materials & Methods  A sedimentary lignite ore (Idaho), ground to pass a 1,000 µm sieve, was used as

Huma® Product: Huma Pro® Mix Background Scientific research shows that humic and fulvic acids are biostimulants—enhancing nutrient availability and uptake, improving plant root growth and mass, and impacting both crop yield and quality. Humic acid products are not all the same. They are marketed in solid

Background Scientific research shows humic and fulvic acids can have a biostimulant effect on plant root growth and mass, nutrient availability and uptake, and crop yield and quality. Objective The objective of this study was to compare and contrast the immediate effects that three types of humic products from Huma®, Inc., have on soybean yield.
