MESA®MethEx-Sulfate of Ammonia

The Only Nitrogen Source That Offers the Synergy of Ammonium Sulfate and Meth-Ex® in One Homogeneous Particle

uf mu historical overview
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

    • Total N 21% (typical)
      • 21% Ammoniacal
      • 24% Sulfur
Ammonium Sulfate
the ammonium sulfate advantage9
Positively charged NH4+ is attracted to negatively charged soil particles and root surfaces. It resists leaching and is non-volatile.The Ammonium Sulfate Advantage
the ammonium sulfate advantage10
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.The Ammonium Sulfate Advantage

Nitrate

the ammonium sulfate advantage12
If too much urea is released at once an excessive amount of negatively charged Nitrate ions (NO3-)become available which leach or volatilize.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

Immediate availability
  • Reduced loss
  • Soluble Sulfur
  • If only the release could be controlled!
The Ammonium Sulfate Advantage
meth ex 40
Meth-EX 40
    • Total N 40%
      • 7% Urea N
      • 11% WIN
      • 22% SAWSN
Meth-Ex 40®
the meth ex advantage25
Old UF technology did a poor job of controlling the ratio of long chain to short chain molecules and the result was lots of HWINThe Meth-EX Advantage

the meth ex advantage27
The very long chain polymers are not predictable and release over a period of months to years. Turf managers had UF banks in their soilThe Meth-EX Advantage

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