Abstract

Abstract Improved agricultural technology has increased yields of cereal crops to a level wherein the crop residues left on the land are of such volume as to interfere with the following crop. Historically, these residues have been incinerated and the practice continues to this day, polluting the air, causing health problems, destroying valuable natural plant foods and soil humus. It is the nature of cereal crop residues to degrade slowly because of their low nitrogen content and complex polysaccharide chemical moieties. This application teaches that by crushing and shredding the crop residue and applying a liquid nutrient enrichment medium for the growth of the native soil microflora decay can be accelerated. Species of fungi such as Rhizopus, Aspergillus, Penicillium, and species of the hay bacillus, Bacillus subtilis, Actinomyces, and the like, all being indigenous soil inhabitants, feeding voraciously on our microbial nutrient enrichment medium, provided as herein described, induce an accelerated rate of decay removing the need for incinerating the crop residue. By means of this disclosure cereal growers may improve their land without harm to the environment. The implementation of this injective, already well known to the art of harvesting cereal crops and culturing an oxidative microflora, enables the owners of combine harvesters to assembly and use the disclosed method of accelerating decay of crop residues.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 57 words
A method for accelerating biodegradation of nutrient-deficient straw residues of cereal grain grown in a field comprising the steps: separating straw from the grain, crushing the straw, applying a nutrient solution containing a humectant selected from the group consisting of molasses, dextrose, malt extract, and invert sugar to the straw, and distributing the straw on the field.
Claim 2
Independent Claim 57 words
A method for accelerating biodegradation of nutrient-deficient straw residues of cereal grain grown in a field comprising the steps: separating straw from the grain, crushing the straw, applying a nutrient solution containing a humectant selected from the group consisting of molasses, dextrose, malt extract, and invert sugar to the straw, and distributing the straw on the field.
Claim 3
Dependent Claim 10 words
The method of claim 1 wherein the humectant is molasses.
Claim 4
Dependent Claim 20 words
The method of claim 2 wherein the humectant at a concentration of about 20 grams per liter of nutrient solution.
