Patent Secured; Geological Agriculture Products Hit the Market

WASHINGTON, Feb. 26, 2016 /PRNewswire/ -- After twenty years of research, the patent for Geological Agriculture has been issued.  On September 1, 2015 the United States Patent and Trademark Office awarded inventor Richard Campbell the design patent 9,119,351 on geological agriculture, the study of using rocks to grow and sustain plants and crops absent the use of any soil and fertilizers ever.  Being a low to no cost alternative, the awarding of the patent represents a significant step forward for the science and in achieving global food security.

Geological agriculture allows consumers, schools, farmers, survivalists and researchers to grow and sustain plants with the use of sedimentary gravel and sand instead of soil and fertilizers while maintaining the nutritional integrity of the food. This technological design shares the configuration to grow nutritious produce in areas laden with droughts, have poor soil quality, poor irrigation methods and faced with high fertilizing costs.  Some say that geological agriculture is a step towards eradicating food deserts around the world and possibly enabling plant life on Mars and elsewhere.
