Advantages of Acetates
for Nutrient Delivery
Small molecules are easily absorbed and plants accept the carrier as a native substance.
Larger compounds can prevent absorption and the plant may reject the foreign carrier.

Effect of EDTA on the Foliar
Absorption of Trace Element Fertilizers
-Samuel P. Stacey & Derrick M. Oosterhuis - University of Arkansas Researchers
EDTA significantly reduces the absorption of Fe and Zn in foliar fertilizers, making it less effective and more costly for farmers. EDTA's high molecular weight and negative charge hinder nutrient uptake through leaf cuticles.
