Biostimulants: Humates

The Green Revolution of the 1960s sought to greatly increase agricultural production through the introduction of high-yield crops, chemical fertilizers, and synthetic herbicides and pesticides. With these new advancements, it was suddenly possible to grow more food on the same number of acres, to better meet the needs of a growing global population. 

One thing that became somewhat overlooked during the Green Revolution (and the decades that followed) was soil organic matter. However, we are finally starting to recognize the value and impact that soil organic matter content has on crops, and actions are being taken to improve it.

Biostimulants: Biologicals - What are they?

As the world’s food demand grows, agricultural food production is also on the rise. This comes with the related challenges of poor yield, drought, pests and weeds that can negatively impact both productivity and the environment.

While fertilizers and pesticides play a significant role in attempting to overcome some of these obstacles, agricultural biologicals can make a crucial contribution toward the goal of making intensive agricultural production more successful and sustainable.

Safe for the environment, biologicals make crops healthier, with improved defenses against diseases and pests, and better able to withstand abiotic stress. The crop is well-prepared for early season growth and has a good vigor, with enriched root and shoot biomass and improved nutrient uptake and use.

Interaction Between the Micronutrients

Graphic-2019-01-21-OMEX-SocialSharing-Nutrients

Of the sixteen nutrients that plants need to grow, develop, reproduce and remain healthy, there are seven that we refer to as micronutrients: zinc (Zn), copper (Cu), manganese (Mn), iron (Fe), boron (B), chloride (Cl) and molybdenum (Mo).

While these nutrients are used in minute amounts, they are just as important to plant growth and development as the macronutrients and secondary nutrients, with some of them playing an important role in controlling key processes and the uptake of macros. For example, molybdenum deficiency reduces nitrogen and phosphorus uptake, while zinc deficiency can reduce overall plant vigor, growth and the uptake of other nutrients.

Interaction Between the Secondary Nutrients: Calcium, Magnesium and Sulfur

As we discussed in our previous blog post, plants require large amounts of macronutrients to grow and thrive. The secondary nutrients – calcium (Ca), magnesium (Mg) and sulfur (S) – are just as vital to plant growth and development, though they are required in lesser amounts than the macros.

Interaction Between the Macros: Nitrogen, Phosphorus and Potassium

Plants require a total of 16 nutrients to grow, develop, reproduce and remain healthy. Three of these nutrients – nitrogen (N), phosphorus (P) and potassium (K) – are required in relatively large amounts. These are known as macronutrients.
