Is your fertilizer approach outdated? 

Traditionally, fertilizer manufacturers have marketed micronutrients on an individual basis, directing growers to apply each through separate application methods. But, that approach increases both costs and complexity for farmers.

Micronutrients make fertilizers more effective

Small doses of essential micronutrients such as boron and zinc can increase yields by supporting macronutrients.—Isn't it time you offered both to your customers?

With our zinc borate fertilizer, Zincubor, you can increase your fertilizer’s value and support better yields for customers. And, because crops only need small amounts of these nutrients, you can get a higher ROI by adding them to your formulation.

Zinc and boron deficient soils tend to occur in the same region and similar conditions.

Superior fertilizer coating technology

Stickiness is a prized trait when it comes to fertilizer coating. Zincubor’s special fertilizer coating technology ensures a durable, even coating on fertilizer granules. That eliminates the potential for dust and results in more consistent coverage in the field.

Perfomance tested

Tests by the International Fertilizer Development Center found Zincubor’s coating performed well on three common fertilizers.

Easy to add

With the right binder material, Zincubor sticks well to fertilizer granules and reduces the potential for dust.
