Micronutrient Deficiency and What to Do About it!

Micronutrients for Plants

There are seven essential micronutrients in plants. Some nutrients control the permeability of a cell membrane and some other control the osmotic pressure, buffer action, etc.

Boron (B), Zinc (Zn), Manganese (Mn), Iron (Fe), Copper (Cu), Molybdenum (Mo), Chlorine (Cl) are some of the important micronutrients for plants. Lack of any of these nutrients affects growth and development.

Boron (B)
Boron is found in tourmaline- a highly insoluble mineral and it is essential for proper forming and strengthening of the cell wall. Boron plays an important role in flowering, fruiting, cell division and pollen germination. Deficiency of boron results in reduced seed and grain production. Boron deficiencies occur generally during drought periods. Excess supply or availability of boron is also harmful to the plant.

Zinc (Zn)
Zinc is an essential element that helps in photosynthesis, energy production and regulation of growth. Zinc deficiency may cause slower maturity and reduction in the size of the leaf. Zinc deficiencies often occur during the cold, wet spring season.

Manganese (Mn)
Manganese is essential for photosynthesis and nitrogen metabolism. Premature leaf drop and delayed maturity are the symptoms of manganese deficiency. Manganese is abundant in wet soils, whereas dry soil has limited manganese.

Iron (Fe)
Iron is essential for energy transfer, nitrogen reduction, and fixation. Iron along with sulfur acts as a catalyst in the formation of other reactions. Yellow leaves are the symptom of Iron deficiency.

Copper (Cu)
Copper is essential for proper photosynthesis, grain production and to the strengthening of a cell wall. Stunted growth, yellow leaves are the symptoms of copper deficiency. There will not be enough copper in many soils.

Molybdenum (Mo)
Molybdenum is responsible for pollen formation. It is also responsible for nitrogen fixation. Reduced fruit or grain growth are the symptoms of Molybdenum deficiency. Sandy soils in the humid region are the places where zinc deficiencies are found.

Chlorine (Cl)
Chlorine is the nutrient that helps in osmosis and ionic balance. It also plays a key role in the process of photosynthesis. Decreased resistance, reduced plant growth are the symptoms of chlorine deficiency

How I treat a Micronutrient Deficiency

BioAG TM-7

All the power of HumiSolve humic and fulvic acid, plus SEVEN Micronutrients required for plant growth. The natural humic and fulvic acids act as chelating agents and prevent tie-up of the trace elements, as well as supplying natural root stimulating compounds. Increases fruit set and quality while stimulating soil microbial activity, improves soil tilth, increases trace element levels and reduces water use. A soluble dry powder for easy shipping and long term storage. Use in a wide variety of applications including dry broadcast for turf and farms, or add to liquid for foliar, hydroponic, irrigation, and hand watered applications. Fantastic when used for compost tea activation.

Guaranteed Analysis:
Copper (Cu)............0.31%
Boron (B).................0.37%
Iron (FE)......................1.2%
Cobalt (Co).............0.05%
Manganese (Mn)......1.2%
Molybdenum (M0)..0.1%

Non-plant food ingredients: Humic 40% & Fulvic 10.5%

Derived from: Boron, cobalt sulfate, copper sulfate, ferrous sulfate, manganese sulfate, sodium molybdenate, zinc sulfate and chelated with humic and fulvic acids derived from freshwater cretaceous humate deposits.

How to Use:

Seed activation:
For seeds soak 24 hours at 0.5g /gal.

Soil and Container plants: 0.75-1.25g/gal of irrigation solution.

Hydroponic: 0.5-0.75g/gal of nutrient solution used in the reservoir (use with every change. Top-offs can be chared with 1/4-1/2 normal rate).

Foliar Rates: .75g/gal every 7-10 days.

Field Use: 2-4 pounds per acre every 3-6 weeks. Pre-Plant Soil

Conditioning/Bioremediation: 5-10 pounds per acre. 1/4 tsp= 1g 1/2tsp= 2g

To Make a Concentrated Liquid Solution:

1. Add 300 grams of TM-7 to one gallon of hot water (110 degrees F) and agitate.
2. After 1 hour, all undissolved solids will have settled.
3. Apply liquid solution at a rate of slightly less than 1/2 ounce per gallon of water.

*Please note approx 15% is insoluble and can be cast in compost or garden. Exceeding application rates can cause irregular growth. Store dry and away from excessive heat.
