Potassium Sulfate Nanopowder is a very important product. It’s used to supply potassium. Conventional agriculture, for the most part, supplies potassium with a muriate of potash or what’s called 0-0-60. We don’t handle that because it has chlorides. It’s potassium chloride which is very detrimental to soil biology.

Potassium Sulfate Nanopowder is that it’s not an extremely high pH fertilizer product. Potassium chloride, on the other hand, is quite a bit higher in pH and has the tendency when used over time to push the pH high and that can be misleading for people that look at pH and then don’t put any calcium or limestone down. Potassium sulfate, because of the sulfate actually, will not push the soil pH. It’s more of a neutral pH, so it’s quite superior just from the aspect of the pH.

Plants and Soils Need the Sulfur:- Most intensely-farmed soils are sulfur deficient. In the past rainfall picked up sulfur out of the air and continuously supplied sulfur with every precipitation. Today with stringent environmental codes and cleaned up smoke stacks the free sulfur is a thing of the past. In order for plants to make oils and sulfur bearing amino acids such as cysteine and methionine the plants need an adequate supply of sulfur in the sulfate form. This is exactly what potassium sulfate supplies.

The application of 100 lbs. of potassium sulfate will give a greater plant response than 200 lbs. of Potassium Sulfate Nanopowder. We have found that 100 lbs. of Potassium Sulfate Nanopowder is quite sufficient for most crops. The only exception to this is high-value, potassium-loving crops such as tomatoes, potatoes, pumpkins, and melons where 200-300 lbs. are used per acre.

Potassium (K) fertilizer is commonly added to improve the yield and quality of plants growing in soils that are lacking an adequate supply of this essential nutrient. Potassium is needed to complete many essential functions in plants, such as activating enzyme reactions, synthesizing proteins, forming starch and sugars, and regulating water flow in cells and leaves. Often, concentrations of K in soil are too low to support healthy plant growth. Potassium sulfate is an excellent source of K nutrition for plants. The K portion of the K2SO4 is no different from other common potash fertilizers .
