What might be some good reasons to consider ammonium sulfate for Pakistani agriculture?

While I have never been to Pakistan, three main reasons come to mind based on what I have read about its soils: They tend to be low in sulfur. Ammonium sulfate is a cost-efficient way to supply

How does ammonium sulfate compare against urea in wheat production?

One of the most obvious benefits of ammonium sulfate when compared to urea is that, in addition to nitrogen, it also supplies sulfur. Wheat research has shown that sufficient sulfur levels are needed for maximum test weights,

How much can I expect soil pH to go down when using ammonium sulfate to provide my crops with the recommended amount of sulfur?

At the low rates required to satisfy a crop’s sulfur needs, the acidifying effect of ammonium sulfate is insignificant – in the order of thousandths of a pH unit. Based on a calculation, for a sulfur rate

How do ammonium sulfate and elemental sulfur compare when it comes to their effect on soil pH?

When either ammonium sulfate or elemental sulfur is applied to provide the sulfur needs of a crop – with the nitrogen supplied by ammonium sulfate or other ammonium nitrogen fertilizers such as anhydrous ammonia, urea, or ammonium

How far into the growing season can you make an ammonium sulfate topdress application to corn without causing damage to it?

Granular Sulf-N ammonium sulfate – which will not stick to the leaves as would products high in fines – and the availability of high clearance, high capacity spreaders have allowed for more and more corn fields to

Can soybeans benefit from ammonium sulfate fertilization?

As legume crops, soybeans normally get most of their nitrogen from the atmosphere. Nevertheless, about 100 pounds of ammonium sulfate at planting can provide the crop a boost before root nodules are actively fixing nitrogen. Ammonium sulfate also

Can livestock benefit from sulfur fertilization on forage crops?

Yes. When there is sulfur deficiency, livestock can benefit from the increased yield and quality of sulfur-fertilized forage crops. Sulfur promotes protein and chlorophyll formation. It also improves vitamin A content and palatability of hay crops and

What role does sulfur play in the plant?

Sulfur is vital in the synthesis of sulfur-containing amino acids – protein’s building blocks. It is also essential in the formation of lipids, vitamins, coenzymes and the chlorophyll molecule. As a result, sulfur not only impacts yield,

How do I know if my crops need supplemental sulfur?

Although the correlation between soil tests for sulfur and crop response to sulfur is not very high, soil testing is often used as a starting point.  A consideration of nitrogen/sulfur ratios in soils is another common approach. 

Don’t crops get plenty of sulfur from smokestack emissions?

Years ago, crops received a good dose of sulfur from electric utilities that released sulfur dioxide through their smokestacks. However, clean air regulations have sharply reduced sulfur dioxide emissions, and as a result, crops are not getting
