HUMIC ACID: It Could Be The Answer To Low Productivity In Our Farms

For the past several years, we have been approached by salespeople who tell us about the wonders of humic acid in enhancing plant growth and productivity. The products come from Europe, United States, China and elsewhere.

We are told that humic acids in the market are not all the same. Some are better than others. For instance, as far as Anthony Cortes, a UP Los Baños graduate who specializes in crop nutrition and soil conditioner products, the one with the highest quality is Diamond Grow Humik, a wettable soluble granule (WSG) from the United States.

Humic acid is not a complete plant food in itself. But when it is applied in the soil combined with the conventional fertilizer, chemical or nonchemical, it improves nutrient availability and uptake. It also improves soil conditions as it increases soil microbial activity.

Diamond Grow Humik can also be sprayed on the leaves to harness the bio-stimulant properties of the product.

The application of humic acid results in the chelation of macro and micronutrients (iron, zinc, manganese, calcium, phosphorus and potassium) for easy nutrient availability to the plant. It also buffers salts that could cause fertilizer “burning”. It likewise binds with fertilizer to reduce “lock up”. It also enhances the water holding capacity of the soil.

There you are. Humic acid can be the answer to the low productivity in our farms.
