1 MESA® MethEx-Sulfate of Ammonia The Only Nitrogen Source That Offers the Synergy of Ammonium Sulfate and Meth-Ex® in One Homogeneous ParticleIntroduction
2 UF/MU Historical Overview Nitroform in the 60’sNutralene/Triaform 70’s & 80’sNutralene technology sold in 1997Trade marks also changed handsMESA developedMESA is the result of ongoing development in the area of polymerization and granulation.MESA has a patent pending.
3 Mesa Is an Exclusive Nitrogen Source That is Produced by Resinating Methylene Ureas with Sulfate of Ammonia to produce anOligomer SulfateExclusive
5 Ammonium Sulfate Ammonium sulfate Total N 21% (typical) 21% Ammoniacal 24% SulfurA very popular N source in many areas with high pH.A common component of many less expensive Ag grade homogeneous products due to relatively low cost and availability.
7 The Ammonium Sulfate Advantage Plants can take Nitrogen ions in both the Ammonium (NH4+) and the Nitrate (NO3-) form.Recent studies have shown increased benefits of the ammonium form of nitrogen in forage and grains.Fred Below University of Illinois—better nutrient accumulation by the plant.Ron Mulford University of Maryland -- increased yield.
8 The Ammonium Sulfate Advantage Ammonium released by ammonium sulfate upon application is immediately available for plant uptake.Ammonium is a soluble source of readily available nitrogen.
9 The Ammonium Sulfate Advantage Positively charged NH4+ is attracted to negatively charged soil particles and root surfaces. It resists leaching and is non-volatile.Ammonium is not subject to denitrificaiton or leaching!
10 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.Nitrates are subject to both denitrification and leaching.
11 Mineralization of Urea Ammonium (Carbonate)UreaseNitrobacterNitrateVolatilizationLeachingPlantUptakeTurf has high organic matter at the soil interface which harbors nitobactor and urease enzymes.Due to the presence of this organic layer the losses of urea to volatilization and leaching can be staggering.
12 The Ammonium Sulfate Advantage If too much urea is released at once an excessive amount of negatively charged Nitrate ions (NO3-)become available which leach or volatilize.
13 The Ammonium Sulfate Advantage Ammonium Sulfate also supplies soluble sulfur.Why is that important?
14 The Ammonium Sulfate Advantage Sulfur ranks forth in importance of the 16 essential elements right behind N, P, & K
15 The Ammonium Sulfate Advantage Sulfur is used in photosynthesis, chlorophyll production and the formation of phospholipids
16 The Ammonium Sulfate Advantage Grasses require about 30 pounds of sulfur per acre, more if clippings are removed.
17 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.Older forms of phosphate fertilizers often contained sulfur such as single superphosphatePurer automobile fuels and reduced sulfur dioxide emissions from factories have greatly reduced the sulfur in the atmosphere.In many areas sulfur can be a hidden hunger because the symptoms of deficiency mimic those of nitrogen.
18 The Ammonium Sulfate Advantage Sulfur works closely with nitrogen to produce plant proteins and in the production of chlorophyll.Sulfur deficiency symptoms first show as yellowing of new growth as opposed to nitrogen where the old growth yellows first. With regular mowing it may be difficult to distinguish sulfur from nitrogen deficiency in turf.
19 The Ammonium Sulfate Advantage Ammonium sulfate is 24% sulfur all of which is soluble and available to the plant.
20 The Ammonium Sulfate Advantage A typical SCU product only contains about 7% sulfur which is insoluble and not readily available.
21 The Ammonium Sulfate Advantage Immediate availabilityReduced lossSoluble SulfurIf only the release could be controlled!
22 Meth-Ex 40® Meth-EX 40 Total N 40% 7% Urea N 11% WIN 22% SAWSN The methylene urea component is made up of:11% long chain WIN molecules1% Dimethylenetriurea (DMTU) a water-soluble condensation product resulting from the reaction of two molecules of formaldehyde with three molecules of urea, with the elimination of two molecules of water, and having a minimum total nitrogen content of 41%.10.5% Methylenediurea, a water soluble condensation product resulting from the reaction of one molecule of formaldehyde with two molecules of urea, with the elimination of one molecule of water. It has a minimum total nitrogen content of 42% and is a source of slowly available nitrogen." (AAPFCO)
24 The Meth-EX AdvantageMethylene ureas are made by reacting urea with formaldehyde to form ureaformaldehyde (UF) polymers
25 The Meth-EX AdvantageOld UF technology did a poor job of controlling the ratio of long chain to short chain molecules and the result was lots of HWIN
26 Water Soluble Nitrogen Methylene UreasTraditional UF MUCTMPUTMTUDMTUUREAMDUOlder ureaformaldehyde products are skewed toward the HWIN chain lengths which last well beyond the season of application and are relatively unpredictable.Water Soluble NitrogenWater Insoluble NHWSNHWIN
27 The Meth-EX AdvantageThe very long chain polymers are not predictable and release over a period of months to years. Turf managers had UF banks in their soilA UF bank refers to nitrogen stored in long chain polymers. When the ratio of long chain polymers is high, over time they can build up in the soil because the application exceeds the rate of mineralization. It is difficult to predict when they will release. They can release at inopportune times due to high rates of microbial activity, for example when temperature and moisture levels are both very high.
31 The Meth-EX AdvantageThe result is a more efficient controlled release nitrogen source where all of the N is available in the season of application.

33 The Meth-EX Advantage Microbial release High AI Extended feeding Excellent colorPredictableLow solubilityEncourages soil microbial activity, release tied to soil temp and moisture to better correlate with plant demand. High AI so more N is used by the plant in the preferred feeding window, result is more efficient feeding.Extended feeding for fewer applications, less labor, more consistent growth and appearance.Consistently rated among the best N sources for color and turf quality.No catastrophic release and almost no loss to volatilization or leaching.
34 The Marriage of Ammonium Sulfate and Meth EX! Total N 30%10.5% Amm.3% urea5% WIN11.5% SAWSN12% SulfurA homogeneous granule that combines the two N sources.There is currently no AOAC methodology to delineate the amount of ammonium sulfate that effectively becomes controlled release due to the influence of the methylene urea reaction.On paper the CRN calculates to 55%.Performance indicates that the CRN includes a significant portion of the Ammoniacal N.
35 MESA Single granule Not a coating Patent pending 100% plant food Ten years in developmentUniversity testedAmmonium sulfate crystal(s) are resinated with methylene ureas molecules. Discrete AS crystals are no longer visible. There may be one or more crystals included in each MESA granule. When the granule is broken there is not a catastrophic release.AOAC method uses ground samples (40 mesh) which are leached with 250ml water. Using un-ground samples the CRN is much higher.
