elemental sulfur

What is the best time to apply sulfur?

It depends on the crop in question as well as the form of sulfur used. While small grains need sulfur early in the season to promote tiller formation, in the case of canola sulfur is more critical

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

How long does it take for elemental sulfur to become available in the soil?

In order to become available to plants, elemental sulfur (ES) first needs to oxidize in the soil, a process governed by several factors: size of granule, hardness of granule, soil temperature, soil moisture, soil biological activity. With

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 there any difference between fertilizing my corn with ammonium sulfate versus elemental sulfur?

Yes. Sulfate sulfur is the only form of sulfur roots take up. The oxidation of elemental sulfur to sulfate sulfur is slow, and factors such as granular size and soil temperature greatly impact the speed of conversion.

What are the advantages of ammonium sulfate versus ammonium thiosulfate?

Ammonium sulfate and ammonium thiosulfate, also known as ATS, are both very common nitrogen and sulfur sources in the dry and liquid fertilizer markets. From an agronomic point of view, I can think of a couple of advantages

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

Do all sulfur fertilizers come in sulfate form?

No. While many fertilizers come in an all-sulfate form, some fertilizers only come in the elemental sulfur form, and some are a combination of elemental sulfur and sulfate. Sulf-N® ammonium sulfate contains 24 units of sulfur – all

What is the difference between using elemental sulfur and sulfate-based fertilizers on crops?

For best results, sulfur applications should be made in the sulfate form, as it is the only form immediately available to crop roots. Crops cannot take up elemental sulfur until it converts into sulfate, which doesn’t start
