Complete Plant Nutrition

What is Plant Nutrition?

Plants use only inorganic minerals for nutrition.  Complex interactions involving decomposition of rocks by lichens and weathering, break down of organic matter by bacteria and mycorrhizae take place to form inorganic nutrient ions in soil solutions.  Note: plants do not take up any organic material.  Roots absorb these inorganic mineral ions if they are readily available in solution.  They can be tied up (become insoluble) by combining with other elements or by alkaline or acidic soils.  If these ions become insoluble due to pH extremes or other causes, plants can no longer take them up.  This means that even though present in the soil, they are unavailable to plants.   Soil microbes also assist in ion uptake by breaking down insoluble compounds releasing the nutrients.

Why Doesn’t My Soil Have What it Takes?

Even in the most well kept garden or greenhouse ideal conditions for uptake of ions may not exist.  Soils do not have all the minerals required for optimum plant growth year after year.  Potting mixes generally contain few, if any, plant nutrients.  They are sterilized and so may lack microbes to break down organic matter.  Within months plants have used the available supply.  Because of plant uptake, mineral nutrients must be replaced in the field or container.

The ABCs or NPKs of The Nutrition Solution®

Dyna-Gro is more than a fertilizer.  Dyna-Gro® is a complete nutrient solution – The Nutrition Solution® – the only formulas containing all the mineral elements required for optimum plant growth in one, easy to use, liquid concentrate.  Ordinary fertilizers are incomplete.  Many simply contain only N-P-K!  Some contain additional elements but are still not complete.  This requires the purchase of multiple incomplete products in an attempt to provide plants with complete nutrition.  Only Dyna-Gro® formulas contain all of the minerals essential for plant growth in one, easy to use, liquid concentrate.  A little known fact is that all plants require more calcium than phosphorus, yet common fertilizers contain enormous amounts of phosphorus and NO calcium.

The Elements of Complete Plant Nutrition

Complete nutrition results in superior plant growth.  Why choose anything less for your plants?

Mineral Nutrients. Green plants must absorb certain minerals through their roots to survive. In the garden, these minerals are supplied by the soil and by the addition of fertilizers such as manure, compost, and fertilizer salts.

There are 21 total elements necessary for optimum plant growth.  7 Macronutrients, required by plants in large amounts: nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and silicon. Air and water supply carbon, hydrogen and oxygen.  And 10 Micronutrients, required in much smaller amounts: iron, sodium, manganese, boron, cobalt, nickel, zinc, copper, molybdenum, and chlorine   Eliminate any of these elements, and plants will display abnormal growth, deficiencies or may not reproduce. The following is a brief guide to the role played by each of these essential nutrient elements.


Nitrogen: Component of proteins, hormones, chlorophyll, vitamins and enzymes.  Promotes stem and leaf growth.  The ammoniacal and nitrate forms are used directly by plants for stem and leaf growth.  The urea form of nitrogen must be broken down by soil borne microorganisms or urease before it can be utilized by the plant.  Urea can cause leaf tip and root burn.  Deficiency symptoms: reduced yields, yellowing of
