American Soil Technologies Expands Marketing Initiatives with P. Allen Smith for the Company's Nutrimoist Product Line.

PACOIMA, Calif. -- American Soil Technologies Inc. (OTCBB:SOYL) announced today that it has entered into a marketing and advertising agreement with Hortus Ltd., P. Allen Smith's television production and media company, to promote its Nutrimoist(R) line.

Smith is an award-winning garden designer, author and host of the public television program, "P. Allen Smith's Garden Home" and the syndicated 30-minute television show "P. Allen Smith Gardens." He has emerged as America's most recognized and respected garden design expert, providing ideas and inspiration through multiple media venues.

Carl Ranno, president and CEO of American Soil Technologies, stated, "Through this established marketing agreement, we expect Allen to draw a great deal of attention to our retail horticulture products and to deliver a significant increase in the sales of our Nutrimoist product line in the retail garden industry."

Smith said, "Nutrimoist gives gardeners an advantage when establishing and maintaining their gardens and containers ... The results are more satisfying."

The Nutrimoist product line includes Nutrimoist Crystals, a cross-linked polymer specifically used to strengthen turf, plants, trees and flowers as a powerful long-lasting soil amendment that greatly reduces the amount of water needed to grow lush plants. Nutrimoist products create optimum conditions for plant growth and have a positive effect on the water and nutrient supply, as well as on the porosity and permeability of soils and potting mixes.

About P. Allen Smith

P. Allen Smith is a fourth-generation nurseryman who owned and operated his own garden center. Smith gained years of practical experience guiding the gardening public before he became a well-known author of gardening books and launched a career in television. Smith is a professional garden designer and talented communicator. After studying garden history and design at the University of Manchester in England through an International Rotary Scholarship and becoming a Certified Fellow of the Royal Horticultural Society, he returned to this country with the mission of inspiring Americans to embrace the joy of creating beautiful gardens. For 10 years, he owned and operated a retail garden center, where his reputation grew as a talented garden designer and popular public speaker. Early in his career, Smith introduced groups to the wonder and beauty of European gardens as a guide and lecturer for private tours. Next came workshops and requests for appearances on local television and radio stations. Soon he created a television production company, Hortus Ltd, offering 90-second gardening reports to local news programs across the country. These short, highly informative spots sparked a desire in viewers for a longer format, so he responded by expanding the reports into a nationally syndicated 30-minute program, "P. Allen Smith Gardens." Visit www.pallensmith.com.
