This slake test shows the difference in soil structure between 10 years of tillage (on the left) and 10 years of pasture (on the right). When dropped into water, the chunk of tilled soil quickly breaks apart as water is drawn into unstable pores. On the other hand, the...

Tillage shreds the arbuscular mycorrhizal fungi [AMF] networks which exude glomalin, a sticky substance that forms soil aggregates. Bare follows, syn N, and chem-tills with GLY also adversely impact AMF.

So compacted pasture soils that result in high runoff and low water infiltration are better? A more informative comparison would have been tillage vs. agroforestry.

Compacted soils don't have the conditions to support the biology that creates and maintains soil structure. They typically fall apart quickly in a slake test.

We stopped tilling 10 years ago. Big difference. Thanks for all you do. Well done.

No-till (with covers) has a similar result…you probably know that but I had to throw in a plug for “bio-mimicry.” It also does better if something was grazing on it (think grazing covers or even in our case grazing winter wheat AND covers)

@pabrailey It’s also roots versus no roots? At what depth, in what time of year and after what crop is the sample taken?

Here is a slake test showing the difference between conventional tillage and no-till soil. This is what happens when water hits your soil, do you want it to hold together or wash away? Adding cover crops improves the soil structure faster than going no till alone. NRCS_Iowa

Every life on the planet depends on water to sustain itself, including the life we cannot see: billions of microorganisms in the soil that make sure the foods that come to our plates are nutritious. However, depletion of organic matter from the soil is putting that in jeopardy. By enriching the soil, we are also providing a better filtration environment for water. Water and soil are not separate: taking care of the soil is taking care of the water. Food and Agriculture Organization Action now:

Revolutionizing Agriculture: The Sustainable Impact of No-Tillage Farming No-tillage farming, also known as zero tillage, is a sustainable agricultural practice that minimizes soil disturbance. Unlike conventional plowing, it keeps the soil intact, preserving its structure and composition. This method significantly reduces soil erosion by up to 90% compared to traditional tillage. It not only enhances soil health by maintaining its natural state but also conserves water by improving water infiltration and retention. It also supports biodiversity and habitat preservation, and mitigates climate change through increased soil organic carbon.

One of the major causes of weak immunity among populations around the world is lack of nutrients in our food and soils. 60% of the world's population is deficient in nutrients like iron due to lack of nutrients in food and soils. Organic matter in the soil improves and helps retain soil structure, leading to improved water quality. This in turn increases food security and reduces the deterioration of the natural ecosystems.

This video was taken in eastern Colorado just 30 minutes after a 1" rain. Notice the ponding and erosion already starting in this recently planted field. This is a symptom of soils that lack biology, and have poor aggregation and structure. They can't absorb water, so the rain runs off instead of soaking in. Without living roots and good soil structure, bare ground struggles to infiltrate rainfall, especially intense storms like this one appears to have been. Healthy soils act like sponges. Here's how we can capture more rain and prevent erosion: - Keep living roots in the ground as much as possible with cover crops - Minimize tillage to preserve soil structure - Build organic matter through residue and compost - & so much more! An overwintered or spring planted cover crop make a huge difference. Those roots host biology that build soil structure, create channels for water infiltration, and hold soil in place when storms hit. What are you doing on your operation to build that sponge? Let us know in the comments. And give us a call today at 402-469-6784 to discuss your spring cover crop plan. #SoilHealth #CoverCropping #CoverCrops #RegenerativeAgriculture

The foundation of soil health comes from the soil microbiome. This incredible reservoir of countless microbial species is the key to making the substances that make up the soil into a live environment, teeming with life. Just like they are the foundation of a healthy soil, they are also foundational to our lives, as our health and wellbeing depends in part on our connection to the soil and its microbiome. #SaveSoil #SoilHealth

For the very first time, Soil–which is the Foundation of Life on this planet– is moving toward centerstage in the ecological narrative.

Checking the state of fields at Spring Farm. Tomorrow will also be assessing other fields in Shurugwi. The rains have been good and it's the right time to quickly apply Ammonium Nitrate or urea. The incumbency is upon the farmer to play their part. Good agricultural practice should be normalized; soil testing and use of appropriate chemicals at the right time. For those like myself, suffering from soul erosion there is a need to use contours. They help fight erosion, promote water retention and support soil structure. Arex should be leading these teaching programs instead of just handing out inputs because some farmers don't even know when to put the contours. Minda yakupera nesoil erosion.

Increasing soil organic matter by just 1% in the top six inches can enhance water retention by around 20,000 gallons per acre (USDA NRCS, 2016). Beneficial soil, acting as a living sponge, plays a vital role in climate resilience. Its sponge-like texture, created by living organisms, soil organic matter, and biological glues, helps absorb substantial water during heavy rainfall. This minimizes the risk of flooding and makes farms with a robust soil sponge more resilient to droughts in dry seasons. The natural filtration processes in healthy soil also purify water, safeguarding ecosystems and human drinking water from pollutants like heavy metals and chemicals.

He’s right. Cows are environmentally sustainable. Methane from cows is part of the natural carbon cycle that after 10-12 years breaks down into natural CO2 and water. Grass absorbs the CO2 by photosynthesis and the cycle repeatedly continues. Cow manure also improves the soil.

This video shows real-time carbon flows inside a mycorrhizal network. Mycorrhizal fungi form a symbiotic relationship with ~ 90% of terrestrial plants and have done so for 400 million years. These specialized fungi provide plants with nutrients and water in exchange for carbon-based exudates the plant produces through photosynthesis. Current estimates say that between 4 and 20 percent of all CO2 pulled in by plants ends up stored in mycorrhizal tissues. Considering plants need to build an entire above-ground structure, a root system, and produce flowers, fruits, and seeds, this is an astounding amount of carbon to allocate to mycorrhizal biomass. A recent review study estimates that global plant communities transfer 13.1 gigatons of CO2 to the underground mycelium of mycorrhizal fungi each year – equivalent to roughly 1/3 of annual CO2 emissions from fossil fuels. The amount of time the carbon is locked up in fungi’s mycelium remains unknown. Nonetheless, the influx of such a massive amount of carbon into the soil is a boon for soil ecology, nutrient cycling, and the health of water cycles. It is no wonder the formation of terrestrial ecosystems largely started with the mycorrhizal fungi/plant partnership. Video credit: @rachaelcargill
