Improve Calcium Uptake
By the Plant

Calcium uptake can be easily achieved with an application of CleanGreen Liquid Calcium.
Calcium in the plant is not necessarily determined by the amount of calcium in the soil.

Clean Green Liquid Calcium was OMRI approved in 2012, but because of costs, it is no longer OMRI listed.  However, it is still the same clean, nature friendly formula.

Since we continue to use the same formula, CleanGreen Liquid Calcium is NOP Compliant

Various organic agencies have approved it on a case by case basis.

Soil is an incredible creation; it has the ability to communicate. If you truly listen, it will tell you exactly what it needs.

Is your soil telling you a story of poverty or prosperity? Here are some of the ways your soil is speaking to you.



When soil is tilled, disced, or plowed and it has hardpan, plowpan, compaction, or lumps, your soil is communicating that minerals are bonding together in unhealthy patterns and will not be available to the plants you want to produce.

Without exception, hardpan, plowpan, compactions, lumps and clumps are letting us know there is a deficiency of available calcium and calcium uptake.


Crops, or weeds

The deficiency of available calcium also plagues your soil and plants with other problems.

There are two basic levels of plant life. Higher plant life, and weeds. Higher plant life, (the crops you grow), flourish in a soil with a high sugar content and proper levels of available minerals.

Weeds, on the other hand, enjoy a low sugar environment and an imbalance of minerals. Your soil grows them in an attempt to correct an imbalance problem. Tech Ag would like to help you to bring your soil back to the healthy balance intended by nature, where crops thrive, and weeds don’t feel at home.


Weeds tells a story

Cockle Burr grows in the deficiency of the availability of the mineral silver. Bull Thistle grows in the deficiency of available zinc. Musk or Canada Thistles grow in the deficiency of available phosphorus, and Leafy Spurge grows in the deficiency of the available nickel. Every mineral has a job.

Without the proper level of calcium uptake, these other trace minerals will not be available to the plant. It is easy to react to symptoms (like weeds) instead of dealing with the problems causing the symptoms.



As the salt in your soil builds, your soil is telling you exactly what’s going on. For example, when dandelions grow, salt is starting to cause a problem.

Next, if you notice along with dandelions, kochia is starting to grow, the salt content is steadily increasing. The next salt loving plant to move in will be foxtail.

If foxtail can't absorb the ever increasing salt content of your soil, the soil then goes dormant.



When you increase the amount of calcium uptake by your plants to a healthy level, it will increase the sugar level in the plant.

It is common knowledge that a sugar content of 13% or more is very beneficial for your plant’s insect resistance. We know that these insects do not have a pancreas and cannot digest high sugar fiber.

The sugar they consume ferments, turns to alcohol, and destroys the plant-feeding insect.

We also know that if sugar content is low, plants will never grow to the extent of their genetic potential. These plants will also be low in minerals, vitamins, amino acids and have poor general nutrition.


Balance soil pH

Low or high PH. When the PH of soil is too high or too low, there is a deficiency of available calcium.

Incredibly, if you balance the minerals in your soil, the pH of your soil will naturally balance itself.



So, is your soil telling you a story of poverty or prosperity?

It desperately needs your help. You can help it by giving it the proper level of available calcium.

Calcium is said to be the “King of crop nutrients”. It is involved in many metabolic and physiological functions. Available calcium is also the referee, mediator and transporter of minerals in the soil.

Without available calcium, none of the other minerals can work at the efficiency needed for optimum plant production.

Now, another calcium choice

Until recently, Dolomite or Gypsum have been about our only choices for improving calcium uptake. But they offer only a small percentage of available calcium to the plant.

AG-USA’s CleanGreen Liquid Calcium is 100% soluble and 100% available to the plant. It is approximately 300 times more available than gypsum or AG lime. It can do the trick for you.

Your soil is trying to talk to you. Listen to it. The symptoms are just your soil’s way of saying it needs help. It needs available calcium.


Unlike Any Other Calcium Product On the Market!

CleanGreen Liquid Calcium is unique in that it is designed to release nutrients and minerals that are in the soil & make them available to the plant.

Cost Comparisons – "Full" rate N vs. "half rate" of N + 3 gal. of liquid Calcium. AG-USA's Liquid Calcium greatly improves N efficiency. Use less N and actually deliver more N to your growing crop, improve plant health and save money. Pounds of Nitrogen per gallon of 28% on this chart is figured at 2.98 lbs.

liquid Calcium. US Ag's Liquid Calcium greatly improves N efficiency.
Use less N and actually deliver more N to your growing crop,
improve plant health and save money. Pounds of Nitrogen per gallon 
of 28% on this chart is figured at 2.98 lbs.

One gallon of 28% N = 2.98 pounds of N. Use 3 gallons Liquid Calcium per acre.  Liquid Calcium price is $6.00 per gallon.  Liquid Calcium Cost = $18 per acre.


Formula to determine pounds of N per ton of 28% liquid fertilizer as follows:
2,000 pounds (1 ton) divided by 10.65 lbs. (weight of 1 gallon of 28%) = 187.79 gallons per ton,
times 2.98 lbs. (pounds of N in 1 gallon of 28%) = 559.6 lbs./ton

*Caution: Do not apply with fertilizers containing phosphate or potash. 
Not compatible with any glyphosate formula, 2,4-D amine or ester herbicides. 
10-34-0 or other commercial phosphate and potash fertilizer formulas can 
gel or clump when mixed with 10% Liquid Calcium.
