The Importance of K

Tobacco removes potassium from the soil at a high rate. Monitoring and keeping up with uptake is critical. Protassium+® premium sulfate of potash (SOP) provides the potassium needed for overall plant growth, durability and leaf quality.

Keep an eye on your K

Deficiency Symptoms

A potassium deficiency may cause mottling and brown or yellow spots on the tips of leaves. Or, leaves may be puckered, with the leaf tips curled under. A deficiency can result  in tobacco grown in sandy soil due to a leeching of potash. The rain can pull the potash below the root zone. Excess rain will also send the message to the roots that they don't have to extend themselves to access moisture so they will never reach the leeched nutrients. 

A threat to quality

Chloride Sensitivity

Tobacco is highly sensitive to chloride. If soil levels exceed 1%, when harvested and cured, tobacco leaves can experience loss in quality and dirty leaf coloring, resulting in unpleasant flavor or aroma and increased hygroscopicity (high moisture retention).

Protassium+ sulfate of potash is virtually chloride-free and has the lowest salt index of all major potassium sources.

Tobacco removes up to 155 lbs. of K2O for every 3,000 lbs. of leaves produced.

High K

A Rich Source of Potassium

The virtually chloride-free composition of Protassium+ fertilizer ensures that tobacco plants won't suffer from chloride toxicity due to fertilizer application. This is one way to fight the often high levels of salt in irrigation water and ground soil. In addition to the 50% potassium that Protassium+ SOP offers, it also provides 17% sulfur in the sulfate form. Sulfate sulfur is readily available for plant uptake and helps with protein synthesis in the plant.

Protassium+ premium sulfate of potash does more to ensure the quality of your tobacco yields, so your yields can do more to ensure your quality of life.
