American Soil Technologies, Inc. Puts Cross-Linked Polymer To Work In The Field

(TULARE, CA) February 8, 2005 - Do polymers really work in agricultural applications? The answer is yes - if you use the appropriate polymer. American Soil Technologies, Inc., a leading supplier of super-absorbent soil amendments worldwide, is providing insight about today's advanced polymers for agricultural use and providing unique tips on what growers should look for when making the best choice for their fields.

All polymers are not created equal. From linear polymers and cross-linked polymers, to the diaper-type polymers that were tried and failed more than a decade ago, today's advanced products offer unique performance characteristics. Stockosorb® cross-linked polymer, designed specifically for agriculture, is quickly garnering growers' praise.

"I've used American Soil Technologies' Stockosorb for five years, in both wet and dry fertilizer blends," says Buzz Shahan, a life-long potato producer from Mesa, Arizona. "This product has significantly increased my plants' ability to uptake fertilizer and the petiole results prove it. I use American Soil Technologies' Stockosorb in potatoes, corn, wheat, and chile crops. It stabilizes the fertilizer by reducing leaching, especially of nitrogen. By maintaining higher moisture levels in the fertilizer placement region, the plants' ability to uptake all elements improve."

The following characteristics are required for a cross-linked polymer:

Release water readily

Potassium-base

Long lasting

High quality and graded-to-size

Cross-linked polymers have been used in the horticultural market for over 30 years, but are a relative newcomer to the agricultural market. Similar to a chain-linked fence, these polymers build on the strength of interwoven links. The bond offers high absorption of water and nutrients under soil pressure and high gel strength, maintaining and improving growers' yields.

"The early diaper-type polymers were not designed to hold and release water readily for plants," states Carl Ranno, president of American Soil Technologies, Inc. "However, this latest generation of agricultural cross-linked polymers retain and easily release water and water-soluble nutrients when plants require them. By conserving these elements, our polymer products can help grow a crop with more efficient use of nutrients, lower pumping costs and improved overall utilization of natural resources."

American Soil Technologies, Inc. attributes the cross-linked polymer's success to precise formulation and design for optimal field performance. "We assist growers in determining if there are any polymer performance-limiting factors on their farms," states Ranno. "We then customize the solution to the unique characteristics of their fields and water source. Growers should consider these polymers to be another tool that give them an edge."

American Soil Technologies, Inc. is a participant in the 2005 World Ag Expo, in Tulare, California, from February 8 to 10. The company booth is located at Pavilion B, booths #2203 and #2204.
