## Overview

The 13-13-13 Super Rainbow 50lb Fertilizer by Irrigation-Mart delivers a balanced blend of nitrogen, phosphorus, and potassium combined with essential micronutrients in uniform granules. Designed for precision feeding, it ensures even nutrient distribution whether broadcast or applied in-row, promoting optimal crop yield and quality across all plant types.

## Description

Precision Feeding 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 will limit yields and reduce the quality of your crop. Rainbow Plant Food is a homogenous, granular fertilizer. Precise amounts of each nutrient – primary and secondary — as well as micronutrients, are chemically compounded to form a homogenous 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. Balanced Nutrition Not only does Rainbow Plant Food include adequate amounts of all essential nutrients, it provides them in the most efficient form for use by the crop.
