Terra Nova Research , LLC's subsurface retention irrigation is the culmination of decades of development. Our patent has 20 improvements over existing devices.
While Subsurface Drip Irrigation ( SDI ) is more efficient than obsolete ditch or pivot which loses 50% to evaporation, membrane captures water for weeks instead of allowing it to drop to the water table in hours.
Subsurface water retention has never resulted in any negative result. In drought areas, it could be the difference between farming and grazing.
Benefits:
1. maximizes yields in extant fields.
2. better quality
3. reduced input costs
seed, water, electricity, diesel, fertilizer
4. renders sandy soils arable
5. promotes drought stress tolerance
6. higher farm-gate cash flow
7. eliminates deep breaking
8. eliminates soil erosion
Our " bravo " ( version 2 ) unit is ready to dig on short notice.
contact us for quotation on custom installation. Price is a function of number of acres, location and amount of membrane required ( orchard or row ). We bring the device and the membrane. You provide the tractor and labor.

Water Bankruptcy Countdown
Dams, Aquifers and even the mighty Mississippi are depleting at an alarming rate with no chance of replenishment. The assumption of stability, of inexhaustible water both above and below ground made a century ago were literally a high water mark.
Examples abound of water authorities and the Army Corps of Engineers resorting to increasingly desperate measures. New Mexico is a harbinger of water rationing. Ironically, farmers watch helplessly as water passes them by due to the Colorado River Compact. California's groundwater protection act is a heartbeat away from old fashioned fallow farming. Las Vegas spent $ 1.4 billion on the " third straw" pipeline to fill Lake Mead and it's still not enough.
When the crisis becomes acute, capture and conservation will become priority.
Our groundbreaking "alpha" version had a short life. Turns out it was not concrete breaking. It literally ran into concrete during a test in 2024. It was like our Kitty Hawk. The small test plot did further substantiate proof of concept. Scroll down for pictures of cotton before and after.
We gave a sneak preview in Lubbock, TX on July 24,2025.

The Technology
Since ancient times, hydrology has been the lifeblood of farming. By capturing rainfall versus allowing water to drain to the water table, crops achieve their maximum potential in terms of yield and quality. While biochar and cover crops help, subsurface membranes are far superior.
Terranova buries thin layers of polymer at about 24 inches below tillage level.
The subsurface film is in multiple rows to allow exchange of air and microbes.
