7 reasons to use potassium sulfate

The following are 7 reasons why potassium sulfate replaces potassium chloride:

1) More Energy for the Money

Commercial fertilizers are concentrated packages of energy. This energy is looked as either producing growth/vegetation or as reproductive/producing seed. Let’s never forget that energy is what grows a crop. Energy is associated with the elements in the fertilizers. Here is the bottom line: One dollar spent on potassium sulfate (K2SO4) will purchase less fertilizer by weight than will one dollar spent on potassium chloride (KCl) but the one dollar spent on potassium sulfate will buy significantly more crop growth energy. Here's why: 47% of potassium chloride is chloride and useless as an element for crop production. In contrast 100% of potassium sulfate is useable by the plant.

2) Lower Salt Index

The salt index is an easy way to judge how damaging a fertilizer is to plant roots and its impact on germination. The higher the salt index the more it can damage roots and kill emerging seedlings resulting in a lower plant population. Potassium sulfate at 46 is less than half of potassium chloride at 116.

3) Better Uptake of Potassium

Proper uptake of potassium requires it to be in the phosphate of potassium form. When there is an excess of chlorides the bonding of potassium with phosphate is blocked. The end result is less potassium uptake into the plant in the preferred form. The high level of chlorides in the soil solution following an application of potassium chloride undermines the very reason it was applied for. The sulfate form does not overwhelm the soil solution with chloride ions and consequently more potassium is taken up by the plant in the phosphate of potassium form.

4) Microbial Stimulation vs. Microbial Suppression
Sulfates have a stimulating effect on the microbial system in the soil, whereas chlorides at high levels are very hard on soil biology . In defense of chlorides I must say that a very small amount is actually beneficial for soil microbes. This modest requirement is easily met by the small amount of chlorides present in potassium sulfate. Chlorides usually run 1-2% in potassium sulfate. High rates of chlorides destroy soil carbons.

5) 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.

6) Good taste of agricultural products
When the potassium absorbed by plants comes from potassium chloride, pastures, vegetables, fruits and taste are not good. Whether we like it or not, this is because plants absorb and use chlorides. When plants absorb potassium sulfate, the taste of vegetables and fruits is excellent, the flavor is excellent, and the yield is more.

7) Small amount but Good effect
The application of 100 kg. of potassium sulfate will give a greater plant response than 200 kg. of potassium chloride. We have found that 100 kg. of potassium sulfate is quite sufficient for most crops. The only exception to this is high-value, potassium-loving crops such as Palm Oil, Durian, Nangka, tomatoes, potatoes, pumpkins, melons and others fruit tree.

Comparison between Potassium Sulfate & Potassium Chloride

DESCRIPTION	POTASSIUM SULFATE	POTASSIUM CHLORIDE
Plant absorption efficiency	100% water soluble. 100% dissolve, absorbed and utilized.	47% is chloride. 53% dissolve.
Effect on soil salt index	Salt content 46 ppm	Salt content 116 ppm
Impact on soil structure	With Sulfur, has the effect of covering and nourishing the soil, balances the soil into neutralization, and enhances the ability of soil to dissolve fertilizer.	There are chlorides and acidic ions will cause soil acidification and at the same time form compaction, which affects the soil's ability to defertilize.
Effect on the growth of soil microorganisms	Effectively help the growth of soil microorganisms.	High chloride content destroys the carbon in the soil and inhibits the growth of soil microorganisms.
Effect on soil phosphorus	Effectively dissolve the fixed phosphate fertilizer in the soil, allowing plants to absorb and reuse it.	There are chlorides and acid ions, which will fix and hardly dissolve the phosphate fertilizer in the soil.
Provide trace elements for soil and plants	Sulfur elements can produce more oil for plants, enhance plant disease resistance, make plants healthier and more yield.	Chloride cannot enhance the disease resistance of plants, but causes more plant diseases and less yield.
The taste and quality of Agricultural Products	The agricultural products have good taste and good quality, especially fruits, which are beautiful and delicious in appearance and original flavour.	Due to the absorption of chlorides, the agricultural products have poor taste, melons are not fragrant, the fruits are not sweet, and the vegetables are tasteless.
Benefits for fruit trees	The fruit quality is better and the yield is more. The oil content of palm oil fruits increases, and the weight increases. The durian is more flavourful, no half-ripe, and can sell for a better price.	Due to the absorption of chloride, the fruit quality is not ideal, and sometimes it will be half-ripe. Cannot increase the oil content and weight of oil palm. Unable to sell at a good price.
Impact on the environment and soil	Environmental protection, safety, does not damage the soil structure, and has the effect of covering and cultivating soil	Destroy soil and environment, cause soil compaction and affect ecology.
Usage comparison	1:2	2:1
Price comparison	RM3,000.0/ton x 1 = RM3,000.0/ton	RM1,500.0/ton x 2 = RMRM3,000.0/ton
