Commonly used N fertilizers for grass hay production include urea, or ammonium sulfate. Urea, with 46% N, is the most concentrated commercial source but must be applied shortly before rain or irrigation to prevent significant loss of the N to …
· Ammonium sulphate fertilizer is a widely used, inorganic soil supplement that has particular benefits when applied to alkaline soils. The active ingredients in it are nitrogen and sulfur . Correct use of this fertilizer maintains healthy nitrogen levels in the soil and, in the case of alkaline soils, helps to maintain a good pH balance.
· All nitrogen fertilizers will increase soil acidity and ammonium sulfate has a slightly higher acidity equivalent than ammonium nitrate. You should be sure to maintain your soil pH above 6.5. Urea (46-0-0) is another option for pasture fertilizer use. Urea is unstable and will volatilize fairly quickly. You should only use urea if the weather ...
Adverse effects resulting from fertilization with high rates of ammonium sulphate were determined on a kikuyu grass (Pennisetum clandestinum) pasture grown on a krasnozem in a sub-tropical environment. Corrective fertilizer practices using lime and phosphorus were evaluated.Ammonium sulphate application (336 kg N/ha/annum for 4 years followed by 672 kg N/ha/annum for 2 …

The band placement of large quantities of Ammonium Sulphate as the main source of N after planting is not recommended. Mixtures of LAN and Ammonium Sulphate in a ratio of 75% LAN : 25% Ammonium Sulphate (marketed as KANAS by some local fertilizer suppliers) combines the optimal benefits of both products and contains 26.25% N and 6% S.
· Where N fertilizers are being used, choosing to apply N as ammonium sulfate will also supply substantial amounts of S. In fact, many fertilizers that might be applied to pasture (magnesium sulfate, 14% S; potassium sulfate, 18% S; potassium magnesium sulfate, 23% S; calcium sulfate; 24% S, or gypsum, 19% S) will supply S as plant available sulfate.
· ammonium nitrate fertilizer for spring and late-summer N applications to tall fescue pastures. Specifically, we have compared ammonium nitrate to ammonium sulfate, urea, coated urea products, and mixtures of ammonium sulfate with urea and mixtures of ammonium sulfate with ESN polymer coated urea as a source of nitrogen for tall fescue. Procedures:
· Ammonium Sulfate The special advantage of this dry form nitrogen fertilizer is that it will not volatalize as a gas when surface-applied on almost all Indiana soils, the exception being calcareous (high lime) soils with pH 7.5 or higher. Therefore, ammonium sulfate makes an excellent topdressing material for wheat and pastures.
· Fertilizers containing sulfate-S include ammonium sulfate (24% S), gypsum (16 to 19% S), and potassium magnesium sulfate (21% S; often called K-Mag or Sul-Po-Mag). Fertilizer dealers also offer fused prills of urea …
One of the most common inquiries I get around this time of year in very dry years goes like this: "I put out fertilizer on my pasture this spring, and it hasn't rained much. I've had very little grass growth. Is the fertilizer still there? If so, how long will it stay there?" The quick answer is it's probably still there. The more informative answer is a bit more involved, but I'll try to ...
To determine the effect of fertilizer treatment on liver trace mineral concentrations in grazing cattle, random liver tissue samples were collected (n = 12; four/treatment) at the start and end of the study period in 2000. Ammonium sulfate fertilization increased (P < 0.001) forage S concentration in both years.
· Ammonium sulfate (21-0-0-25S) and ammonium nitrate (34-0-0) are the best materials for N-only starters. There is an important precaution associated with certain fertilizer materials. Diammonium phosphate (DAP; 18-46-0) and …
· Addition of Ammonium Sulfate (AMS) Over the last 10 years more and more people have been adding fertilizer solutions to herbicides in their tank mix to increase control of undesirable plants. Ammonium sulfate, ammonium nitrate or urea plus ammonium nitrate added to spray tanks has been shown that it can increase efficacy of postemergent herbicides.
Timing pasture nitrogen fertilizer applications. Timely N fertilization can help increase total production, extend spring grass growth into the early summer, and . extend fall pasture production into early winter. Kentucky bluegrass and the more productive, tall grasses such as smooth bromegrass, orchardgrass, tall fescue, and reed
· Possible S fertilizer sources include ammonium sulfate, potassium magnesium sulfate, gypsum and elemental sulfur. The most economical choice depends on local availability and the need for the other elements in the fertilizer. Micronutrients

USES. Ammonium Sulphate will meet short term sulphur deficits of crops and pastures, crop quality requirements, or the maintenance sulphur requirements of pasture. Ammonium Sulphate Granular is reccommended for arable and cropping situations, silo fills and drilling seed. It is used in Cropmaster, Ammo 31 and Ammo 36 blends.
· February. Because all fertilizer application should be made during cool weather, the effectiveness of urea, ammonium sulfate and ammonium nitrate should be equal. Table 2.
