acidification

Is it possible to create a reservoir of sulfur in the soil through the continuous application of elemental sulfur?

Yes, it is possible to create a reservoir of sulfur through long-term application of elemental sulfur. Be aware, though, that elemental sulfur oxidation produces acidity. So, with time, it may gradually decrease soil pH to the point

What is the acidification effect of ammonium sulfate placed in a band, such as with strip-till?

The acidification effect of ammonium sulfate applied in a band will depend on several factors – particularly its rate of application and the buffer capacity of the soil in question. Having said that, by applying ammonium sulfate

How would elemental sulfur compare against ammonium sulfate for decreasing soil pH from 7.3 to 6.3?

It depends on the rates used. Applied at rates that just cover a crop’s sulfur needs, neither one would do, regardless of the soil type. When thinking of these products as soil amendments, 200 to 400 pounds

Is ammonium sulfate good for pecan trees in Texas? If so, how much?

As a matter of fact, ammonium sulfate is recommended more than other nitrogen sources on high pH soils (common in Texas) because of its acidifying effect. It temporarily increases the availability of micronutrients, such as iron and

How much can I expect soil pH to go down when using ammonium sulfate to supply all of my crop’s nitrogen needs?

At rates of several hundred pounds of ammonium sulfate per acre, the acidifying effect of ammonium sulfate would be in the order of hundredths of a pH unit. Based on a nitrogen rate of 140 pounds per

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 does ammonium sulfate compare with other nitrogen sources when it comes to soil acidification and liming needs?

While ammonium sulfate is more acidifying than anhydrous ammonia, urea, or ammonium nitrate, its acidifying effect on soil is significantly less than traditionally assumed. If applied to supply 100 percent of a crop’s nitrogen needs, ammonium sulfate
