HumiSul 90S is an effective soil amendment when used to correct alkali, saline and high pH soils by lowering soil pH through acidification. HumiSul 90S promotes efficient absorption and metabolism of NPK and other essential plant nutrients when used on soils requiring treatment. When HumiSul 90S is exposed to moisture, chemical and biological processes produce beneficial results and, particularly when broadcast in the fall, has the added benefit of freeze-thaw for even more thorough disintegration and availability. Repeat applications of HumiSul 90S, over time, improves the soil by building sulfur oxidizing bacteria (Thiobacillus) populations that cause a number of important benefits including soil acidification. The addition of humic acid to the sulfur pastilles aids by further increasing soil microbial activity that helps add organic matter back to the soil.
*Promotes efficient absorption and metabolism of plant nutrients.
*Ideal for quick pH correction in saline/alkali soils under good soil management.

Directions of Use:
HumiSul 90S is only to be used to amend agricultural soil to correct soil pH based on soil analysis and should be applied based on the calculations and advice of a professional agronomist or a qualified agricultural consultant. The application rate should be based on the expected reduction in pH when a particular volume of HumiSul 90S is applied. It is best applied by uniform broadcasting over the area to be treated and incorporated to the depth a professional agronomist or a qualified agricultural consultant has recommended, to effect a change in soil pH.
