Yield and quality. Quality and Yield. No matter how you slice and dice them, these are the two most critical factors that determine a vegetable crop's profitability and feeding value. Like children, vegetables demand high levels of nutrients, particularly as management intensifies. With this in mind, balanced fertilization is critical, and the balanced nutrition in Super Rainbow Plant Food helps farmers grow the best vegetables they can grow.

The Granular Advantage of Super Rainbow presents the premium fertilizer choice for high-value crops such as vegetables. When high yields and quality are critical, growers rely on this naturally occurring source of essential nutrients to produce a healthy and bountiful crop. Inside its tiny granular shell, the product contains potassium, magnesium, zinc, boron, manganese, calcium and sulfur. Outside the shell, Super Rainbow boasts for you higher yields and fatter paychecks.

A Balanced Diet: Super Rainbow is like an energy bar for your crops – it packs a punch of all of the nutrients critical to healthy growth. All vegetable crops are different, but especially in the early stages, high-yielding vegetables require large amounts of potassium to stimulate root growth. Too much of this nutrient, however, can restrict plant absorption of magnesium, which is essential for chlorophyll production. That’s why every granule of Super Rainbow Plant Food supplies the perfect balance of potassium and magnesium. Super Rainbow for vegetables also incorporates zinc, manganese, calcium, and boron, which promotes cell elasticity and plump fruits. In addition, Super Rainbow boasts sulfur – the perfect mineral to spur a crop’s ability to process nitrogen, promoting health across the board.

Readily Available Nutrients: Nutrients in Super Rainbow Plant Food exist in a highly available water-soluble sulfate form, so they can move quickly through the soil profile to reach vegetable roots in time to promote healthy, hearty crops.

Easy on Sensitive Crops: While most potassium sources contain chloride that may reduce the quality of sensitive crops and shorten shelf life, Super Rainbow does not. Because of this low chloride level, vegetable growers can use Super Rainbow with confidence. With our product, your bounty will be bountiful.

Doesn't Affect Soil pH: If your pH isn't balanced, then nothing works. Don’t worry! Super Rainbow is a neutral salt and does not increase soil acidity, regardless of the amount applied to your vegetable crops.

Easy One-Time Application: Since Super Rainbow is totally water soluble, it keeps working throughout the growing season. A good time to lime and fertilize an established vegetable patch is after the last cutting of one season and first harvest of the following one. Typically growers apply between 200 to 600 pounds of Super Rainbow per acre.
