Salt Index Facts
Excessive salt in the soil solution can lead to root diseases such at Phytophthora, reduce the ability of Rhizobium to convert nitrogen to feed the plant, and reduce the plants’ water uptake capability, all potentially leading to damage and reduced yields.
Due to its low salt index; less than 8, growers can apply SUL4R-PLUS in furrow without concern for incremental salt injury to seed.
