16-4-8 Super Rainbow or 16-4-8 Graco

To produce the best yields and highest quality, your crops need all of the essential plant nutrients. Even if adequate amounts of the primary nutrients – nitrogen, phosphorous and potassium – are available, a shortage of one or more secondary or micronutrient could limit yields and reduce the quality of your crop.

Rainbow Plant Food is a homogeneous, granular fertilizer. Precise amounts of each nutrient – primary and secondary – as well as micronutrients, are chemically compounded to form a homogeneous mixture. As a result, each granule contains nearly identical amounts of all the ingredients. Granules are uniform in size, shape and weight, so the fertilizer spreads evenly. Whether you broadcast or apply it in-row, every plant across the field will have the necessary nutrients available when it’s needed most.
