We believe that once you have given GroPal Balance a try you will be convinced by what you see! Pastor Andrew Curtiss was:

My experience with the GroPal Balance was excellent.  I grow CSA and farm market vegetables on a plot of land around 1 acre in size. It is land that had been used for conventional agriculture for 30 years prior to 2015.  On your recommendation I applied an equivalent of 40 oz. of Gro-Pal Balance to the acre in May of 2015.

To say I was impressed may be an understatement.  I planted 75 pounds of seed potatoes. My final potato harvest was in the 1200 pound range.  For nearly 6 weeks my shell peas produced large quantities of the sweetest peas I have grown. We picked off of our bush snap beans for over 6 weeks. When I quit picking them they were still flowering. By that time we had become completely sick of picking beans.

Overall the flavor of our produce this last year was exceptional. At the farmers market I was told every week how excellent our produce was. I have no doubt the Gro-Pal Balance was a major factor.

What impressed me the most was the plants ability to deal with stress. In mid-June we had almost five inches of rain in two days. I thought for sure I was going to loose half the garden, as it was under water for almost 12 hours. The plants pushed through. What followed was 21 days without rain. Never once in that time did I see a wilted plant.

When it came time to tear the garden down, I was blown away by the mycorrhizal fungi all over the roots of our plants. I firmly believe that symbiotic relationship between plant and root was the key to our success in 2015. The root structures were amazing. God's creation is truly amazing!  Thanks for an awesome product.


Having said all this, we still carry all the products listed on

Science:  Discovering the principles which God established, and learning to work in harmony with them.

Our soils are a complex thing.  Tech-Ag has been working since 1969 to understand the mysteries of what makes nutrition work – in animals, in plants, and in soils.  We have found that bacteria play an incredible role in living things.  Bacteria are the life or death of the soil.  By encouraging good bacteria activity, we can literally turn soils around, and bring them back to health and full production. GroPal Balance does a wonderful job at this.

How do we encourage good bacterial activity?

·         Increase the humus in the soil, promoting water retention and air flow (most beneficial bacteria require oxygen for their existence).

·         Introduce beneficial strains of bacteria back into the soil.

·         Provide food sources for bacteria, which then break down the nutrients so they are available to the plant.

·         Remove the toxins and salts which hinder bacterial life.

·         Replace trace minerals, which bacteria can then make available to the plant.

 As soil quality declines, the problems we must face increase.


As we deal with the problems which arise from poor soil, we can further damage the soil.


Insect problems:   Apply pesticides, whose toxins hurt our soils.

Nematodes:   Apply nematicides, which kill everything in their path, including beneficial bacteria.

Weeds:   Apply herbicides, which often use salt as a carrier.

Water:   Irrigate, which brings more salts to the soil.



We need to refocus our attention on the core issue – the life of the soil.


What are the real issues with our soils?


Bacterial activity:   Bacteria are the chemists of the soil.  They break down complex nutrients, and make

  them available to the plant.


Ø          Organic matter:   We need to find new and effective ways to increase organic matter.

Ø          Salts and toxins:  They negatively influence productivity.

Ø          Trace minerals:   By not replacing these, we have mined them from our soils.

Ø          Top soil:             Deeper top soils mean more nutrients available to the plant.



What can be done on a limited budget?


How do we build up our soils with our limited resources?  Many of you are already putting in place conservation measures to help your soil.  Measures such as no till, strip till, etc.


What else can be done?  It has taken us many years to get to our present state of poor soils.  Getting our soils back into shape will also be a marathon run, not a sprint. However, GroPal Balance can greatly increase the pace at which soil is restored to pristine health.


We at AG-USA don’t have all the answers, but we have found enough answers to help you to reverse the trend of “death” in your soil.  For 33 years, we have sat at the feet of men who have devoted their lives to researching the “whys” of plant and animal nutrition.  We have come to some significant understanding of why we are where we are today, and how we can get our soils back into shape.  Finally, we have sought out products which address the core issues.


Now some Good News!!!  Using GroPal Balance won’t cost you a penny more to use. In fact, you will likely save a lot of money on inputs, which maintaining or improving production.


We have already helped hundreds of farmers to restore the life in their soil, and to return their farms to greater profitability.  Every year that farmers use our products, their soils are improving.  This means that every year profitability is increasing!
