Plant Nutrition and Deficiency Symptoms
Keep your plants healthy:
Nitrogen (N)
Dried Blood, Garden Manure, Cottonseed Meal, Ammonium Sulfate, Urea
Organic farming and gardening methods focus on feeding the soil and not the plants. Reliance on synthetic fertilizers and most chemical pesticides are avoided completely. The organic grower focuses on the importance of all micro organisms in the soil and the ability they have to release natural nutrients found in composted organic materials. Although the Major Nutrients known as
(N), (P) and (K) are needed in the greatest quantities, a deficiency of any one nutrient listed here can prevent plant growth, or reduce it to unsatisfactory levels.
Using synthetic fertilizers and pesticides often destroy the natural balance of the soil food web and breeds diseases. This allows for an overpopulation of damaging insects to develop. The organic grower produces a healthier more nutritional food that is better tasting and protects the environment and the food produced.
Understanding the soil food web and how plants interact with it is fundamental to growing a healthy, abundant crop.
Phosphorus (P)
Rock Phosphate, Bone Meal, Single Super Phosphate, Triple Super Phosphate
Potassium (K)
Sulfate of Potash, Sulfate of Potash Magnesia, Muriate of Potash, Greensand, Kelp.
Macronutrients
Cobalt (Co) and Sodium (Na)
A cobalt deficiency may be indicated by Reduced growth and
yellowing of foliage. Sodium deficiency can lead to a wilted appearance for a prolonged period of time. Plant stress from over and under watering may also cause plants to wilt.
Below is the most potent, effective and highest quality slow-release organic fertilizer ever offered to the public. Check it out.
Atlantic Kelp Meal, Ocean Fish Bone Meal, Tennessee Rock Phosphate, Granulated Feather Meal:, Mag (also known as Sul-Po-Mag or Langbeinite): A natural Potassium-Magnesium-Sulfur complex that supplies these essential plant and animal nutrients in a readily available form. 22% Sulfur, 22% potash (K2O), 11% Magnesium. Natural Potassium Sulfate: This is the natural-mined form, from the Great Salt Lake in Utah. Contains 50% potash (K2O) and 17% Sulfur. Chilean Nitrate of Soda: From the Atacama desert of Chile, the only known source of naturally occuring nitrate in mineral form. Unlike ammonia Nitrogen from animal or vegetable sources, Nitrate N is readily available to plant roots in cold soil.
Azomite tm : The "A to Z of Minerals Including Trace Elements" is where Azomite got its name. Its source is layer of volcanic ash in Utah that spent millions of years absorbing trace minerals from an ancient sea.
Glacial Rock Dust: Freshly ground from the glacial moraines left behind in the Pacific NW USA at the end of the last Ice Age. Contains a mix of minerals swept up from a vast area.
Paramagnetic Basalt: From Ontario, Canada, a highly paramagnetic basalt rock, freshly crushed. 8,000-10,000 uCGS. Boosts seed sprouting, stimulates rapid growth and early maturity.
Iron, Manganese, Copper, Zinc and Boron: A perfectly balanced blend of these essential minerals from purified sources.
MycoApply® Endo/Ecto : Beneficial fungi can increase nutrient uptake and water efficiency by ten times. MycoApply Endo/Ecto is a blend of 4 Species Endo mycorrhizae and 7 Species Ecto mycorrizae. The various fungi in MycoApply Endo/Ecto will adapt to your soil, with the ones that are best suited to your climate and garden becoming established.

Keep your plants healthy:
Nitrogen (N)
- Symptoms: Older leaves, generally at the bottom of the plant, will yellow. Remaining foliage is often light green. Stems may also yellow and may become spindly. Growth slows.
- Sources: Any compound containing the words: 'nitrate', 'ammonium' or 'urea'. Also manure.
- Notes: Many forms of nitrogen are water soluble. Our atmosphere is composed of 78% Nitrogen. Our planet is 75% water.

Phosphorus (P)
- Symptoms: Small leaves that may take on a reddish-purple tint. Leaf tips can look burnt and older leaves become almost black. Reduced fruit or seed production.
- Sources: Compounds containing the words 'phosphate' or 'bone'. Also greensand.
- Notes: Very dependent on pH range.
Rock Phosphate, Bone Meal, Single Super Phosphate, Triple Super Phosphate
Potassium (K)
- Symptoms: Older leaves may look scorched around the edges and/or wilted. Interveinal chlorosis (yellowing between the leaf veins) develops.
- Sources: Compounds containing the words 'potassium' or 'potash'.
Sulfate of Potash, Sulfate of Potash Magnesia, Muriate of Potash, Greensand, Kelp.
Macronutrients
- Calcium (Ca)
- Symptoms: New leaves are distorted or hook shaped. The growing tip may die. Contributes to blossom end rot in tomatoes and also tip burn of cabbage.
- Sources: Any compound containing the word 'calcium'. Also gypsum.
- Notes: Not often a deficiency problem and too much will inhibit other nutrients.
- Magnesium (Mg)
- Symptoms: Slow growth and leaves turn pale yellow, sometimes just on the outer edges. New growth may be yellow with dark spots.
- Sources: Compounds containing the word 'magnesium', such as Epson Salts.
- Sulfur (S)
- Symptoms: New growth turns pale yellow, older growth stays green. Stunts growth.
- Sources: Compounds containing the word 'sulfate'.
- Notes: More prevalent in dry weather.
- Boron (B)
- Symptoms: Poor stem and root growth. Terminal (end) buds may die. Witches brooms sometimes form.
- Sources: Compounds containing the words 'borax' or 'borate'.
Copper (Cu)- Symptoms: Stunted growth. Leaves can become limp, curl, or drop. Seed stalks also become limp and bend over.
- Sources: Compounds containing the words 'copper', 'cupric' or 'cuprous'.
Manganese (Mn)- Symptoms: Growth slows. Younger leaves turn pale yellow, often starting between veins. May develop dark or dead spots. Leaves, shoots and fruit diminished in size. Failure to bloom.
- Sources: Compounds containing the words 'manganese' or 'manganese'
Molybdenum (Mo)- Symptoms: Older leaves yellow, remaining foliage turns light green. Leaves can become narrow and distorted.
- Sources: Compounds containing the words 'molybdate' or 'molybdic'.
- Notes: Sometimes confused with nitrogen deficiency.
Zinc (Zn)- Symptoms: Yellowing between veins of new growth. Terminal (end) leaves may form a rosette.
- Sources: Compounds containing the word 'zinc'.
- Notes: Can become limited in higher pH.
Cobalt (Co) and Sodium (Na)
A cobalt deficiency may be indicated by Reduced growth and
yellowing of foliage. Sodium deficiency can lead to a wilted appearance for a prolonged period of time. Plant stress from over and under watering may also cause plants to wilt.
