While trying to solve these, we’ve found an enjoyable and profitable way of farming.” “Because we don’t have a lot of expenses for purchased inputs, that makes us profitable. On this and other types of cover crops we can get 3 to 4 pounds a gain per head per day.
“Mycorrhizal fungi have to be present in order for soil aggregates to be built,” says Brown. Scientists previously thought that soil was a lifeless medium built up over hundreds and hundreds of years of decaying organic matter on top of the soil.
We further reduce living soil to dirt through excessive applications of pesticides and herbicides.By keeping the soil surface covered with plant material, mulch and animal manure, we can shield those beneficial soil organisms from lethal UV light exposure.
Stormwater runoff, droughts, and soil loss become mitigated when we have healthy soils that can store water for longer periods of time. It is the arrangement of these aggregates that are the pore spaces that allow water to infiltrate the soil profile. Brown frequently addresses farm audiences across North America.
These root exudates are also the building blocks for soil aggregates. They are mimicking nature by growing very diverse cover crops and then trampling them with Ultra High Density livestock grazing. Futures: at least 10 minute delayed. Everyday we hear of soil scientists, farmers, and gardeners alike discovering something new about the rich world under our feet: soil! To graze yearlings on cover crops, the Browns use temporary fencing to cross-fence fields. Here at Ecology Artisans, we prefer to simplify things to empower our clients and future customers to go out and do this great work for themselves.Gabe Brown is a farmer / rancher in Bismarck, North Dakota.
Regenerative agricultural practices produce more organic matter and feed soil life. They rotate the cattle through these small paddocks in a daily series of moves. North Dakota Rancher Gabe Brown was able to increase his organic matter from 1.8% to 5% with a host of practices. “In infiltration tests done by scientists studying our ranch, water infiltrates our soil at a rate of 1 inch in nine seconds,” says Brown. In the late 1990s, Gabe and Shelly Brown had a four-year run of bad luck on their crop farm near Bismarck, North Dakota. To see all exchange delays and terms of use, please see
“Historically, soil scientists tell us that the soil organic matter of some Northern Plains regions like ours was as high as 7% in the pre-European-settlement period. “Historically, soil scientists tell us that the soil organic matter of some Northern Plains regions like ours was as high as 7% in the pre-European-settlement period. More carbon in the soil equals more organic matter to feed the plant and soak up the rainfall when it comes.
They also direct-market grass-finished lambs from a flock of ewes, along with eggs from 1,000 free-range laying hens. Any gardener or backyard farmer can see that the trampled cover crops create a great mulch layer. When the soil is covered, we also keep the soil surface cooler which decreases evaporation and minimizes the erosive impact of rain. “On some fields we might use an herbicide about every third year.” All this is because their soil now teems with life and restored health. Dr. Christine Jones is a soil scientist out of Australia, and she came up with the term, the "liquid carbon pathway." While 3,000 acres of grassland is committed to the rotational grazing of 300 beef cows and 400 to 800 stockers, the 2,200 acres of cropland grow corn, spring wheat, oats, barley, peas, rye, and sunflowers.
Most are marketed directly to consumers as grass-finished beef. These, along with short-season cover crops, provide grazing for 250 stocker cattle. Another key to improving soil health is keeping the ground covered at all times. Therefore, constant tillage and disturbance denudes the soil life and structure created by carbon and the liquid carbon pathway. “The second inch of water infiltrates in 16 seconds.” Because it’s well watered, undisturbed by tillage, and fed a constant diet of live roots and recycled plant residue along with livestock manure and urine, the soil is populated with mycorrhizal fungi. “I started asking, ‘How can I farm without expensive inputs?’ Searching for the answer to that question sent me down a path of learning about the way soil functions. “Money was extremely tight,” says Gabe Brown.
