Benefits of technology

"The present invention provides a method for growing a crop in soil by introducing a chlorine dioxide solution to suspend weed and pathogen growth. The chlorine dioxide solution decomposes in the soil and provides nutrients for the crops. The method is safe for the crop and the environment. The chlorine dioxide solution can be easily applied to the crops through the irrigation system. The method also involves preparing the first solution by combining water, PBTC, and hydrochloric acid, which results in the decomposed chlorine dioxide providing nutrients to the crops. The method also involves covering the soil with water to make it more active and susceptible to the growth-suspending effects of chlorine dioxide. The technical effects of the invention include improved crop yield and reduced weed and pathogen growth."

Problems solved by technology

They would increase stresses from nematodes, insects and disease, and adversely effect product quality.
Also, harvest effacy is diminished due to pickers inability to find and pick produce in weedy growth.
Unwanted vegetation increases production costs by adding control costs up to several hundred dollars per acre.

example

[0019]Water (27.5%), PBTC (17.5%) and hydrochloric acid (HCl) (55%) were admixed to form a first solution. Water (85%) and sodium chlorite (15%) were admixed to form a second solution. The first and second solutions were combined to form a combined solution. Sufficient contact time was allowed in the mixing vessel 12 to convert a substantial portion of the sodium chlorite solution into chlorine dioxide. The combined solution can also be referred to as chlorine dioxide. For test purposes, five soil beds were prepared. These beds were covered with sheet plastic. In the first bed, 150 ppm of chlorine dioxide was added irrigation water and the mixture was introduced to the soil bed until the soil bed was saturated. In the second soil bed, 350 ppm of chlorine dioxide was added to irrigation water and the mixture was introduced into the second soil bed until the second soil bed was saturated. The third soil bed received 750 ppm of chlorine dioxide in irrigation water until that bed was sa...

Abstract

Introducing chlorine dioxide solution into an agricultural soil in an amount effective to suspend weed and pathogen growth in the soil. The chlorine dioxide is allowed to decompose in the soil. Then, a crop is planted in the treated soil. The decomposed chlorine dioxide provides nutrients for the crops as they grow.

Description

TECHNICAL FIELD[0001]This invention relates to a method of suspending weed and pathogen growth in soil prior to growing a crop in the soil. More particularly, it relates a method of introducing chlorine dioxide into the soil in an amount sufficient to suspend weed and pathogen growth and then planting and growing a crop in the treated soil.BACKGROUND OF THE INVENTION[0002]It is known to treat plant growing soil with fumigants to prevent the harmful effects of invasive weeds and other unwanted vegetation and pathogens. If allowed to grow, these invasive plants would compete with the agricultural crops for water, minerals and sunlight. They would increase stresses from nematodes, insects and disease, and adversely effect product quality. Also, harvest effacy is diminished due to pickers inability to find and pick produce in weedy growth. Unwanted vegetation increases production costs by adding control costs up to several hundred dollars per acre.[0003]Methyl-bromide (M-b) has been the...
