Not All Chelates Are Equal.

PAC is NutriAg’s proprietary, natural plant-derived chelation technology used in a wide variety of products.

To successfully foliar feed, fertilizers must be true solutions. They are often in the form of salts or chelates. Salts are not ideal because of the potential to burn the crop. Using chelates to form true solutions is a more effective and safe way to foliar feed.

Chelates can come from many sources and they differ in their efficiency for foliar application. Understanding the differences can separate the average products from the exceptional.

Chelates nutrients using plant-derived carbohydrates.

Optimizes usage by the plant.

Enhances nutrient uptake.

Foliar Entry Into the Plant

There are two major pathways into the plant:

Not the most efficient route, primarily on the underside of leaves and open and close based on time of day/ environmental conditions.

Polar Pores:
Pathways through the cuticle that form where polar regions of the waxy cuticle absorb water from the inside of the leaf and the atmosphere.

Benefits of PAC


True Solutions

PAC chelates nutrients to help form true solutions.



Plant cuticles are negatively charged, PAC is neutral



Polar pores are 1-5 nm, PAC carbohydrates combined with micronutrients are 0.77 nm.

Safe and

Easily recognized/ metabolized by the plant.

PAC carbohydrates are naturally occurring.

Excellent tank-mix compatibility.

Chelation prevents interactions of ions in the spray tank.

Safe to apply.

Greenhouse tests conducted at high rates demonstrate the safety of PAC.


Equal amounts of manganese were applied to a section of a corn plant. Even at a high rate, MangaMax was safe whereas, the Mn-EDTA resulted in necrosis and chlorosis.


Competitor Manganese

On the Crop vs In the Crop

Equal amounts of manganese were applied. Leaf tips were harvested 3 days after spotting the product on a separate area. ManMax got significantly more Mn into the leaf and moved into unsprayed tissue.
