High pH soils with excess free lime and high salinity are particularly challenging.
Terra Ferra helps overcome these challenges by chelating iron with NutriAg’s proprietary
PAC Technology to ensure nutrient availability and a strong start to the season. 

NATURAL CHELATION

Unique PAC Technology keeps iron available in harsh soil conditions to deliver easily metabolized nutrition to the crop.

AVOID IRON UPTAKE ISSUES

Ideal option at planting for high pH soil applications.

 

HIGHLY COMPATIBLE

Exceptional tank-mix compatibility compared to competitors.

CROP SAFE

Safe and effective formulation.

Analysis

Sulfur (S)                        3.4%

Iron (Fe)                        4.0%

Application Rate:

Soil/Fertigation: 1.0-4.0 qt /ac

Data from the Field:

Crop: Soybean (PS 2020 XRN)
Years: 2022
Location: NutriAg Greenhouse
Soil pH: 7.7
Design: RCBD
Treatment: An untreated check was compared to treatments with equal amounts of Fe applied in-furrow with the seed in a volume of 5 gal/ac.
A dry FeEDDHA (6% Fe) was applied at 2.3 lbs/ac, and Terra Ferra
(4% Fe) was applied at a rate of 1.27 qt/ac. 

Plants were harvested one month after planting for biomass.

Crop: Citrus (var. Cara Cara Navel)
Years: 2021
Location: Reedley, CA
Soil pH: 7.37
Design: RCBD
Treatment: : (soil applied during last 3h of irrigation)
Grower Standard Practice (GSP) was compared to treatments with Terra Ferra (4% Fe applied at 2.0 qt/ac), or to Fe-EDDHSA 
(2% Fe at 4.0 qt/ac).
