Low Salt Index Fertilizer | Protassium+

Avoid the Burn

Salt Index

Salt index is used to give an indication of the effect a fertilizer can have on a soil system. Sodium nitrate has a salt index of 100 and serves as the standard for comparing relative salt content. When comparing the salt index per unit of K2O, Protassium+® has the lowest of all major potassium sources. This allows you to avoid many of the problems that salt poses,  including:

• Poor germination
• Nutritional imbalances
• Seedling injury and "Tip Burn"
• Stunted root and shoot growth
• Reduced soil structure and decreased microbial activity
