The soil on both tomato test beds are similar in that we brought the nutritional level up to a 65% base saturation of Calcium, 15% Magnesium, 6% Potassium, and matched the minor nutrients as closely as we could – growing in a 6.4 pH. The difference is clear in the addition of NuTech’s Formula 100 to the bed on the left. All plants were planted at the same time and receive water through an automatic drip system.

I used NuTech’s Formula 100 four years ago on my tomatoes that go to the local Farmers Market. This year I was going to use it again but I got behind and failed to order in time for planting so I left the minerals out of my cultural program. Was that ever a mistake! I had disease issues, poor quality and low yield. My customers really noticed the difference and they let me know it. I will never skip using your soil amendments again!

I have used your product for the past 7 years and without doubt it is by far the best soil amendment that I have ever used. I cannot recommend it highly enough.

I have been planting my garden in the same soil for years. I have noticed the quality and quantity of my harvest vary from year to year. But I haven’t been “Wowed” in a long time. I know about crop rotation, compost and proper fertilizers, but I never expected to see a 25% bump in yield using your soil amendment. Looking forward to getting my bragging rights back!

I grow rice on alkali soils west of Willows. I use your Formula 100 because it mitigates root pruning that occurs under alkali soil conditions. I believe I get a better stand of rice under adverse soil and weather conditions. My head rice quality is consistently higher than that of my neighbors growing the same varieties as I do. I suspect that the mycorrhizae help the plant remain green after draining and maintain a more even kernel moisture as the field dries at harvest time.
