I DO NOT PROVIDE APPLICATION RATES. REASEARCH ONLINE YOUR PLANTS, VEGETABLES OR LAWN USES BEFORE ORDERING! I purchase fertilizer in bulk. I weigh it on state inspected digital scales so you do get the actual weight of fertilizer you order. The fertilizer is placed in plastic zip lock bags. 

10-20-20 is used primarily to aid the plant in setting fruit, or more specifically to reduce fruit abortion.  Effectiveness has been strong not only on all of the vegetable and fruit crops, but cotton as well … encouraging the cotton plant to hang on to several additional squares.  With a balanced nutrient profile, it is a high energy product due to the high levels of sugars, and is very high in all of the essential trace minerals.  In field trial after field trial, fruit set has been increased, as well as the flavor of the crop itself … bringing more of the genetic potential to the forefront.

In cotton, it is common to observe not only additional squares being set, but, when examining the more mature bolls, there will usually be higher seed counts.  10-20-20 performs best if adequate nitrogen is present in the soil, or can be coupled with a more vegetative formulation such as 28-16-7.  10-20-20 is a key component in our approach to growing foods “nutrient dense” foods.  It is the backbone of our produce programs, and may be applied either as a fertigation additive through drip lines or a foliar with virtually no “burn” when used as directed

Nutrients in Fertilizer

Plants need several types of nutrients. Macronutrients are necessary in large quantities. Those that may not be easily available in soil in the right amount are the primary nutrients you find in fertilizer:

  • Nitrogen for plant growth, leaf development and the production of vivid, green color
  • Phosphorous for root growth and the creation of fruit, seeds and flowers
  • Potassium — sometimes called potash — for root development and resistance to drought and disease 

Secondary nutrients — oxygen, carbon, hydrogen, calcium, magnesium and sulfur — are also necessary macronutrients but are often available in soil or air. Micronutrients — including boron, chlorine, cobalt, copper, iron, manganese, molybdenum, nickel and zinc — are needed only in small amounts.

Before you shop for fertilizer, perform a soil test. You can purchase a home test kit, or send a soil sample to your local cooperative extension office for testing. The results will tell you what to add to the soil to make it ideal for the plants you plan to grow.

How to Read Fertilizer Numbers

Three prominent numbers on a fertilizer package — known as the NPK value, guaranteed analysis or fertilizer grade — tell you the percentage of available primary macronutrients by weight in the package:

  • Nitrogen (N) content is the first number.
  • Phosphorous (P) content is the second number.
  • Potassium (K) content is the third number

Granular fertilizers deliver food to a plant slowly but have the advantage of longevity.

Broadcast application
This method, which covers large areas well, is used to apply granular fer­tilizers to lawns or to new beds before they are planted. The broadcast method can be done with a hand-rotary or drop spreader.

Top-dress application
This technique, which provides nutrients to individual plants such as shrubs and perennials, is done by hand with granular fertilizers. Simply apply the fertilizer around the base of the plant, extending to the drip line. For vegetables, place the fertilizer in a strip parallel to the plant­ing row.
