The typical recommendation would be prior to planting. Nevertheless, if weather conditions prevent your from spreading it pre-planting, you may also apply it post-planting. Purdue university work has shown yield responses to 100 pounds per acre of …

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 …
Certainly! Like grain and forage crops, vegetables also need nitrogen and sulfur for photosynthesis and protein formation. As a matter of fact, many industrial vegetable growers include ammonium sulfate as part of their basal fertilization blend.
Yes. Phosphorus is adsorbed to soil minerals in a stronger fashion than sulfur, so excessive phosphorus reduces sulfur efficiency as more sulfur is displaced via leaching. The organic phosphorus in litter may also reduce zinc availability.
Yes. As a matter of fact, hard red winter wheat research at Virginia Tech has shown that nitrogen and sulfur are key in obtaining increased grain protein quantity and quality. This makes sense given that both of …
This is not the first time I have been asked this question – I assume the confusion comes from the “S” in its name. While polymer-coated urea does not supply any sulfur, it is very commonly blended …
Given that plant-available sulfur in the soil is mobile, the best way to go about taking soil samples for sulfur testing is to get soil as well as sub-soil samples and have them tested separately.
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 …
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 …
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 …
