MESA®

MMethEEx-SSulfate of AAmmonia

The Only Nitrogen Source That Offers the Synergy of

Ammonium Sulfate and Meth-Ex® in One

Homogeneous Particle


• Nitroform in the 60’s• Nutralene/Triaform

70’s & 80’s• Nutralene technology

sold in 1997• Trade marks also

changed hands

• MESA developed

UF/MUHistorical Overview


Mesa Is an Exclusive Nitrogen Source

That is Produced by Resinating

Methylene Ureas with Sulfate of

Ammonia to produce an

Oligomer Sulfate


A Closer Look at the Two

Components of MESA


Ammonium Sulfate

• Ammonium sulfate Total N 21%

(typical) 21% Ammoniacal 24% Sulfur


The Ammonium

Sulfate Advantage


The Ammonium Sulfate Advantage

• Plants can take Nitrogen ions in both the Ammonium (NH4

+) and the Nitrate (NO3

-) form.



• Ammonium released by ammonium sulfate upon application is immediately available for plant uptake.



• Positively charged NH4

+ is attracted to negatively charged soil particles and root surfaces. It resists leaching and is non-volatile.



• By contrast urea is broken down rapidly in soils by urease enzymes to form negatively charged Nitrates. As much as 40% loss can occur in 7-10 days.

Mineralization of Urea



• If too much urea is released at once an excessive amount of negatively charged Nitrate ions (NO3

-)become available which leach or volatilize.



• Ammonium Sulfate also supplies soluble sulfur.

• Why is that important?



• Sulfur ranks forth in importance of the 16 essential elements right behind N, P, & K



• Sulfur is used in photosynthesis, chlorophyll production and the formation of phospholipids



• Grasses require about 30 pounds of sulfur per acre, more if clippings are removed.



• The use of modern fertilizers, the switch to unleaded gas, and the clean air act of 1990 have all removed sulfur from the atmosphere.



• Sulfur works closely with nitrogen to produce plant proteins and in the production of chlorophyll.



• Ammonium sulfate is 24% sulfur all of which is soluble and available to the plant.



• A typical SCU product only contains about 7% sulfur which is insoluble and not readily available.



• Immediate availability

• Reduced loss• Soluble Sulfur• If only the

release could be controlled!


Meth-Ex 40®

• Meth-EX 40 Total N 40%

7% Urea N 11% WIN 22% SAWSN


The Meth-EX Advantage



• Methylene ureas are made by reacting urea with formaldehyde to form ureaformaldehyde (UF) polymers



• Old UF technology did a poor job of controlling the ratio of long chain to short chain molecules and the result was lots of HWIN

• The very long chain polymers are not predictable and release over a period of months to years. Turf managers had UF banks in their soil

• Meth EX brand improves on traditional methylene ureas by precisely controlling the ratio of long, medium, and short length polymers.

• The result is a more efficient controlled release nitrogen source where all of the N is available in the season of application.
