As a Sweet Potato grower, you know quality is just as important as weight when your sweet potatoes get to the pack house. Outside of weather, nothing influences quality and yields more than your fertilizer program. For sweet potatoes, balanced fertilization is critical, and the balanced nutrition in Rainbow fertilizers helps farmers grow the best sweet potatoes possible.
Basic NPK is not enough. Practically all soils in the coastal plain are in a boron & manganese deficient area, so unless a good available boron & manganese source is supplied in your fertilizer, your crop may suffer. When high yields and quality are critical, growers rely on Rainbow fertilizers to produce a healthy and bountiful crop.
A Balanced Diet:
Rainbow provides all of the nutrients critical to healthy growth. Every granule of Rainbow supplies the perfect balance of boron and manganese.
Readily Available Nutrients:
Nutrients in Rainbow fertilizers exist in a highly available water-soluble sulfate form, so they can move quickly to reach sweet potato roots in time to promote healthy, hearty crops.
