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.

Turf

Take the worry out of maintaining healthy turf while having the exceptional performance you demand. All of our Rainbow Lawn Grades consistently stand out from the competition.

  • Even spreading – each granule contains nearly identical amounts of all nutrients
  • Balanced Nutrition – nutrients are provided in the most efficient form for use
  • Nitrogen is ammoniacal – resistant to leaching and volatilization

A Balanced Diet:

Rainbow provides all the nutrients critical to maintaining healthy turf. Every granule of Rainbow supplies the perfect balance of necessary nutrients.

Readily Available Nutrients:

Nutrients in Rainbow fertilizers exist in a highly available water-soluble sulfate form, so they can move quickly to reach the roots in time to promote a healthy, hearty turf crop.

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.

Cool-season grasses like bluegrasses and fescues will benefit from the majority of nitrogen being applied in late summer or fall, whereas spring and summer applications are best suited to established warm-season grasses. Consider your soil, grass type and climate to best determine when application is suitable to reduce the opportunity for runoff or leaching.

Geographic location also plays a big role in soil type and will impact when the ideal time is for you to apply.
