Take it from the growers who know:

“Our farm received a yield increase for soybeans treated with

EDDHA Fe compared to the soybean plants that did not receive

the treatment. The soybeans treated were visually healthier

than those without. We will continue to use EDDHA Fe in the

future to increase plant yields.” David Haas, Madison, MN

“I applied EDDHA Fe to fields that have produced low yields

over the last 40 to 50 years. These same fields had up to 5 bu/

acre more than the fields that traditionally produce the highest

crop yields, and were not treated with the product. We also

found that there were no areas of non-yielding plants in the

fields that received treatment, where traditionally, 20% of these

same fields are non-yielding. We will use it on EVERY acre of

soybean crops next season.“ Bill O’Leary, Danvers, MN

A simple, proven fact:

IRONWORKS WORKS!

Summary of AG Specialties 2011 Iron Development Work

I. Introduction –

In efforts to support initial market introduction of a generic Iron EDDHA source, AG

Specialties funded two university research studies and four grower demonstration trials in

2011. The objective of these trials was to compare the efficacy of ‘IronWorks’ brand Iron

EDDHA to Soygreen when applied at equivalent rates of Fe(o,o-EDDHA) on dry beans in

western Nebraska and on soybeans grown in west central and northwestern MN.

II. Summary of Results –

A. Dry Bean Study:

This study was conducted by Dr. Gary Hergert at the Panhandle Research and Extension

Center in Scottsbluff, NE. A copy of Dr. Hergert's final report is attached for your review.

Gary indicated they did not have a significant iron chlorosis evident during this study.

Overall, we did get a positive iron response on 2 of the 4 varieties evaluated. IronWorks

and Soygreen were similar in yield performance in this study. On the two Pinto varieties,

there was an advantage in going to the 3.0 pound / acre rate with IronWorks as noted in

the table below. An early hail storm did thin the plant populations which was not ideal;

yields , however, were still considered good (in the 3000 pounds per acre range).

Iron Source Product Rate Fe(o,o-EDDHA) Rate Yield Increase over Control (lbs. / A) ( lbs./A ) ( lbs. / A ) Poncho Montrose Average Control 0.0 0.0 - - - - - - - - - - - - - - IronWorks 1.5 0.06 270 130 200 IronWorks 3.0 0.12 400 310 355 Soygreen 1.25 0.06 240 160 200 ------------------------------------------------------------------------------------------------------------------------- Method of Application: Powdered products applied as liquid mixtures in-furrow at planting; volumes were 6 gallons per acre to facilitate uniform application.

B. Soybean Study:

This study was conducted by Dr. John Wiersma at the UM- Crookston Research Center. A

copy Dr. Wiersma’s final report is attached for your review. This study was designed to

compare the powder forms of IronWorks and Soygreen applied as liquid mixtures. In

addition, we included several granular polymer-coated Fe- EDDHA prototypes for initial

evaluation.

- 2 –

Additional irrigation was supplemented across this study to encourage leaching of the iron

chelate sources. An additional 5.32 inches of irrigation water was applied in June and 3.5

inches in July. Total rainfall + irrigation water for the late May through August period was

17.52 inches compared to a 'normal' of ~10 inches. Basically, IronWorks and Soygreen performed very similar in terms of crop growth and

yield. At the flowering stage (50 - 60 days after emergence; ~R2), both IronWorks and

Soygreen exhibited improved growth over the control (no iron) based on plant height

measurements (average of + 3.6") and less chlorosis as measured by IDC ratings. In early

September (104 days after emergence), a height difference of ~4.2" was still evident. In

terms of yield, the Fe-EDDHA mixtures averaged an additional 5.6 bu / A over the control. The Polymer Coated AS-C-1016-C prototype (TRT 5) stood-out in this study as being a

consistent performer in terms of improved crop growth and yield ( 9.8 bu / A increase).

Other polymer-coated prototypes were similar to the IronWorks liquid mixture. The concept

of a controlled release Fe-EDDHA source appears to be technically feasible based on this

study.

C. Grower Demonstration Trials:

Several demonstration trials were conducted with selected farmers in the Crookston area

and near Benson, MN. These trials were designed as non-replicated strip trials to compare

the agronomic performance of IronWorks compared to Soygreen based on comparable rates

of ortho,ortho-EDDHA iron. A non-treated strip was included in most studies to serve as a

“negative, no iron control”. The wet spring conditions through-out April and May made it

difficult to find growers willing to cooperate and to select fields with a past history of iron

chlorosis. David Genereux of the Centrol Consulting Group did an excellent job of lining up

three sites in the Crookston area. Dick Bonde spent considerable time trying to line-up

growers in the Benson area and was able to secure one site the last week of planting.

Results from these demonstration trials are presented in Tables 1 and 2 (pages 3 & 4).

Overall, IronWorks brand Iron EDDHA provided comparable performance to Soygreen when

applied at (or near) equal rates of ortho, ortho-EDDHA Iron. These larger scale trials also

provided excellent feed-back from the cooperating growers regarding product usage and

feasibility.

D. Key Findings:

-1.) On alkaline soils, the amount of ortho, ortho- (o,o-) Fe EDDHA applied in soil

applications is the key to obtaining an agronomic response on iron sensitive crops (i.e.

soybeans, etc.) irrespective of o,o- analysis, manufacturer and / or brand.

- 3 –

-2.) Grower demonstration trials comparing IronWorks brand Fe EDDHA versus

Soygreen showed comparable performance over-all when applied at equal o,o- rates.

-3.) The yield of soybeans treated with one polymer coated Fe EDDHA prototype (Exp.

AS-C-1016-C) was significantly better than the same Fe EDDHA source applied as a liquid.

Improved growth and yield were consistent throughout the growing season when compared

to the no iron control. This warrants further investigation.

variety is rated a 4 on Monsanto's scale with 1 being the best and 10 being the worst for IDC

tolerance. A variety with moderate IDC tolerance and good yield potential in its maturity class.

We compared a new liquid suspension with 4# of Ironworks in 5 gal./ acres of water with 4# of

Soygreen in 5 gal of water I acre.

In this first set of strips the check had very noticeable IDC problems with soybeans only

5-6" tall in spots. Right next to those burned down spots there were 3 112' plus tall treated

soybeans. Those IDC burn down spots were still green with very few pods and poor bean

development when it froze Sept. 15th. Virtually nothing to add to the yield in those spots.

During the growing season there was very little IDC effect on the beans treated with the

Ironworks and the Soygreen. I rated the soybeans equal in appearance between the Ironworks

treated and the Soygreen treated strips during my visits to the plot during the growing season.

On Oct. 2 we harvested plot strips 12- 30" rows wide- 562' long with the following results. Moisture Test Weight Yield Yield improvement

The check strip 9.3 57.6 27.82 for treated strips

Over 113 of the check strip showed IDC problems

Soygreen at 4# I acre 9.3 59.1 37.69 +9.87

Ironworks at 4# I acre 9.3 57.5 40.38 +12.56

Farther south in the same field we repeated the comparisons on the full length of the field.

On that portion of the field we didn't see much sign of IDC problems this year. I could see a little

sign of IDC late June - early July but they grew out of it as the season progressed.

Oct. 2 they harvested 2264' long strips of 12-30" row strips with the following harvested results. Moisture Test Weight Yield

Looking at the results shows the Ironworks treated soybean yields being comparable to those treated with

Soygreen with equal amounts of product.

Retention and Mobility of Iron EDDHA in soil systems: Laboratory studies proving some basic information on the

fate of applied iron chelates. -Article Highlights-

# 1.) In a leaching column study using a sandy loam textured soil mixed with sand (82.5% total sand content), 85 to 90% of the applied ortho, ortho (o,o-) EDDHA / Fe leached through the soil system after 28 days. In this study, 0.71 inches of water was applied every two (2) days.

Approximately 50% of the applied o,o- EDDHA / Fe leached through the columns after six (6) days

and the addition of 2.1" of water. After 10 days and 3.55" of water, only ~25% remained in the soil system available for plant uptake. (See PP leaching curves and figure 3 in the attachments.)

# 2.) No ortho, para (o,p-) EDDHA / Fe was found in the leachates indicating its short-lived stability in

alkaline soils.

# 3.) The "batch" experiments in the article represent closed soil systems where no leaching occurs. These are basically soil incubation studies designed to evaluate stability of iron chelate sources over time. The Batch 1 experiment referenced in Figure 1 is looking at stability in a soil slurry system (5 grams soil + 25 ml of liquid) after 3 days. The Batch 2 experiment is more typical of an actual field situation (except no leaching); it is designed to evaluate iron chelate stability over time using the same soil mixture as in the leaching columns. Figure 2 shows the amount of iron chelate remaining in the soil solution over a 33 day period.

# 4.) In a second publication out of The Netherlands (partially funded by AkzoNobel), Fe-EDDHA

fractions were separated out into pure solutions and applied to soybean plants grown on a calcareous clay soil under greenhouse conditions for an 8 week period. One of the key findings was the addition of o,p- Fe EDDHA to iron deficient plants showed no response and the plants looked similar to the control. This tends to confirm that in alkaline soil systems, o,p- Fe EDDHA has limited agronomic efficacy due to its short-lived stability. The o,p- Fe EDDHA fraction does, however, provide value as a "guarding mechanism" by exchanging iron for copper on reactive soil surfaces; this helps maintain the stability and effectiveness of o,o- Fe EDDHA isomers.
