APPLICATION RECOMMENDATIONS
Test Your Soil
Maximum economic yield begins with a soil test to determine key soil nutrients your crops need. Your own experience, combined with soil testing is the first step to achieving a high yielding, high quality crop. Regular soil testing and the use of the appropriate Rainbow Plant Food grades will help you achieve complete nutritional balance for your crops.
Corn
As a corn grower, you know that maximum economic yields are the way to profitability. Outside of weather, nothing influences quality and yields more than your fertilizer program. Corn needs a proper balance of nutrients to grow. Basic NPK is not enough. Unless a good available secondary and micronutrient source is supplied in your fertilizer, your crop may suffer. The best source for these nutrients is with a fertilizer that can give you uniform coverage in the fields.
When high yields and quality are critical, growers can rely on Rainbow fertilizers to provide the essential nutrients necessary to produce a healthy and bountiful crop. Inside its tiny granular shell, the product contains potassium, magnesium, zinc, boron, manganese, calcium and sulfur. The right combination for the highest quality crops.
Readily Available Nutrients:
Nutrients in Rainbow fertilizers exist in a highly available water-soluble sulfate form, so they can move quickly through the soil profile to reach roots in time to promote healthy, hearty crops.
Application Recommendation:
There are certain variables you’ll want to consider before applying Rainbow Plant Food to feed your crops. It’s important to know what is already in your soil prior to deciding on additional nutrients. Soil testing is the first step to understanding what your crops need. Knowing what is in your soil will help to avoid over-application of any nutrient, and subsequently avoid a toxicity problem that could negatively impact your yields.
Geographic location also plays a big role in soil type and will impact when the ideal time is for you to apply.
Traditional row crop types will generally only need one application of Rainbow Plant Food. In general, we recommend applying Rainbow Plant Food five to seven days before planting for most row crop types. If you miss the pre-plant window, apply right after planting. Waiting any longer than this may result in loss of yield, as your plant will be searching for its missing nutrients, putting it in a stressed state.
