MESA MESA ® MethEx-Sulfate of Ammonia 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/MU Historical 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
Plants can take Nitrogen ions in both the Ammonium (NH 4 + ) and the Nitrate (NO 3 - ) form.
The Ammonium Sulfate Advantage Ammonium released by ammonium sulfate upon application is immediately available for plant uptake.
The Ammonium Sulfate Advantage Positively charged NH 4 + is attracted to negatively charged soil particles and root surfaces. It resists leaching and is non-volatile.
The Ammonium Sulfate Advantage 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.
Urea Ammonium (Carbonate) Urease Nitrobacter Nitrate Volatilization Leaching Plant Uptake Mineralization of Urea
The Ammonium Sulfate Advantage If too much urea is released at once an excessive amount of negatively charged Nitrate ions (NO 3 - )become available which leach or volatilize.
The Ammonium Sulfate Advantage Ammonium Sulfate also supplies soluble sulfur. Why is that important?
The Ammonium Sulfate Advantage Sulfur ranks forth in importance of the 16 essential elements right behind N, P, & K
The Ammonium Sulfate Advantage Sulfur is used in photosynthesis, chlorophyll production and the formation of phospholipids
The Ammonium Sulfate Advantage Grasses require about 30 pounds of sulfur per acre, more if clippings are removed.
The Ammonium Sulfate Advantage The use of modern fertilizers, the switch to unleaded gas, and the clean air act of 1990 have all removed sulfur from the atmosphere.
The Ammonium Sulfate Advantage Sulfur works closely with nitrogen to produce plant proteins and in the production of chlorophyll.
The Ammonium Sulfate Advantage Ammonium sulfate is 24% sulfur all of which is soluble and available to the plant.
The Ammonium Sulfate Advantage A typical SCU product only contains about 7% sulfur which is insoluble and not readily available.
The Ammonium Sulfate Advantage 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
The Meth-EX Advantage 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
UREA Water Soluble NitrogenWater Insoluble N HWSNHWIN MDU Methylene Ureas DMTU TMTU TMPU Traditional UF MUC
The Meth-EX Advantage 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
Methylene Ureas Weeks of Release
The Meth-EX Advantage Meth EX brand improves on traditional methylene ureas by precisely controlling the ratio of long, medium, and short length polymers.
UREA Water Soluble NitrogenWater Insoluble N HWSNHWIN MDU Methylene Ureas DMTU TMTU TMPU High Activity MUC
The Meth-EX Advantage The result is a more efficient controlled release nitrogen source where all of the N is available in the season of application.
Methylene Ureas Meth-Ex 40 Traditional UF 40% N 38% N OWSN9.4 HWSN3.1 Really Good Stuff Good Stuff HWSN17.7 HWIN Meth-Ex 40 has twice as much RGS (78% vs 38%) 15/38 = 39% 31.4/40 = 78%
Microbial release High AI Extended feeding Excellent color Predictable Low solubility The Meth-EX Advantage

Features Advantages & Benefits
Features of Ammonium Sulfate Soluble sulfur Ammoniacal N Quick response Deep green color Acidification
Features of Meth-EX 40 Predictable High activity index No flush growth Controlled release Long feeding
Features of MESA Excellent color No flush growth Predictable Fast response Long feeding No foliar burn
Compared to Coated Products No catastrophic release, lock off Reduced clipping yields Longer feeding Less loss to leaching or volatilization
Compared to Homogenous AM Products Not 100% Soluble Longer duration No reliance on coated products for CRN Greatly reduced potential foliar burning
