Pasture treatments for enhanced carbon sequestration and reduction in livestock-produced greenhouse gas emissions
The subject invention provides compositions and methods for reducing deleterious atmospheric gases and/or precursors thereof using livestock feed additives and/or supplements. In preferred embodiments, a multi-purpose composition comprising one or more beneficial microorganisms and/or one or more microbial growth by-products is applied to livestock animals' feed and/or to a field or pasture where livestock animals graze. In some embodiments, the composition controls methanogenic bacteria. In some embodiments, the composition enhances carbon sequestration in the field or pasture by promoting plant health and/or growth.
1. A method for killing a methanogenic microorganism in a livestock animal's digestive system, the method comprising applying a composition comprising one or more non-genetically-modified beneficial microorganisms and one or more growth by-products thereof to a field or pasture, said field or pasture comprising grasses and/or other plants upon which livestock animals graze, and placing the livestock animals in the field or pasture to graze,
wherein the livestock animals ingest the composition in addition to the grasses and/or other plants, wherein at least one of the one or more beneficial microorganisms is Bacillus amyloliquefaciens NRRL B-67928 at a concentration of about 1×10 6 to about 1×10 13 CFU/ml of the composition, wherein the one or more growth by-products are lipopeptide biosurfactants, and wherein the killing of the methanogenic microorganism reduces enteric deleterious atmospheric gases and/or precursors thereof.
2. The method of claim 1 , wherein the livestock animals are ruminants.
3. The method of claim 1 , wherein the method further comprises applying an additional microorganism selected from Bacillus subtilis, Pleurotus ostreatus and Saccharomyces boulardii.
4. The method of claim 1 , wherein the microbial growth by-products are in crude form, said crude form comprising a supernatant resulting from fermentation of a microorganism that produces said growth by-products.
5. The method of claim 1 , further comprising applying a prebiotic with the one or more beneficial microorganisms and/or one or more microbial growth by-products, wherein the prebiotic is dry animal fodder, straw, hay, alfalfa, grains, forage, grass, fruits, vegetables, oats, crop residue, kelp extract, humic acid, fulvic acid, and/or humate.
6. The method of claim 1 , further comprising applying one or more of the following components: seaweed; kelp; 3-nitrooxypropanol; anthraquinones; ionophores selected from monensin and lasalocid; polyphenols selected from saponins and tannins; organosulfurs; garlic extract; flavonoids selected from quercetin, rutin, kaempferol, naringin, and anthocyanidins; bioflavonoids isolated from green citrus fruits, rose hips and/or black currants; carboxylic acid; and terpenes selected from d-limonene, pinene and citrus extracts.
7. The method of claim 1 , further comprising applying the one or more microorganisms and/or one or more microbial growth by-products to drinking water and/or to supplemental feed that the livestock animals ingest.
8. The method of claim 1 , wherein said method enhances plant and microbial biomass in the soil of the field or pasture, thereby producing a carbon sink in the field or pasture.
9. The method of claim 1 , wherein the deleterious atmospheric gas is methane or carbon dioxide and/or the deleterious atmospheric gas precursor is nitrogen and/or ammonia.
10. The method of claim 1 , further comprising assessing the effect of the method on the reduction of enteric deleterious atmospheric gas emissions and/or precursors thereof in the livestock animal's digestive system and/or waste.
11. The method of claim 1 , further comprising assessing the effect of the method on the control of methanogenic bacteria and/or protozoa in the livestock animal's digestive system and/or waste.
12. The method of claim 1 , further comprising assessing the effect of the method on the sequestration of carbon in the field or pasture.
13. The method of claim 1 , used for reducing the number of carbon credits used by an operator involved in livestock production.
