MAJOR 90™: The All Round Sulfur Solution

Sulfur is the fourth most essential nutrient for healthy crops following nitrogen, phosphorous and potassium. MAJOR 90™ is a high analysis, prill-shaped, Sulfur fertilizer utilized for crop nutrition as well as a soil amendment. Applications of MAJOR 90™ will improve soil Sulfur levels as well as help lower soil pH and increase nutrient availability.

The unique spherical shape of MAJOR 90™ makes it ideal for blending with other solid N, P, K fertilizers. Additionally, the bentonite clay incorporated in each MAJOR 90™ prill absorbs moisture and finely divides the elemental Sulfur into small particles that convert into plant-available sulfate Sulfur by soil microbes.
