Adoption of no-till cultivation alone is good for #SoilHealth but does not sequester carbon. In this new paper in @Geoderma_Jrnl, Andong Cai compiled 1061 paired comparisons from 144 studies. (1/5)…
There were large gains in the top 10 cm but these were more than offset by losses deeper in the soil profile. (2/5)
Critically, the data was divided by time and the initial whole profile losses were slowly closed so that by 15 years there was no difference in soil carbon between tilled and no-till fields. (3/5)

1. #NgarachuSoil
The study of soil organic carbon levels is important in understanding optimal #SoilHealth when dealing with #conservation.

This involves both the chemical and physical properties of the #soil
2. #NgarachuSoil
Within #StokeParkEstate, an investigation was carried out to find out whether Total Organic Carbon (TOC), and Total Carbon (TC) vary in land type;

Woodland and Meadow🏞️
3. #NgarachuSoil
It was found that both TOC and TC levels had a visible dip from woodland to meadow between the 0 and 20m distance that was measured.

However, the results did not show a consistent decrease in both variables in the 25metres measured from woodland to meadow.

FINALLY our new manuscript is out in @FrontiersIn! Env outcomes of #regenerative multi-species #grazing at @whiteoakpasture w/ full LCA + soil C data

We find support for regenerative ag's potential to help mitigate #climatechange & restore #soilhealth!…
Top-line findings:

- @whiteoakpasture was sequestering 2.29 Mg C/ha/yr, which lowered its LCA footprint by 80%

- when comparing this to commodity animal production, @whiteoakpasture had a 66% lower GHG footprint after considering soil C
- multi-species pasture rotation *did* require more land to produce the same amount of food compared to commodity
- however, this land was restored from degraded cropland (peanut/cotton)
- in short - this does NOT mean that MSPR = deforestation/land use change from native lands

Scenic beauty on the way to Everglade Farm @EvergladeFarm yesterday. At msl 1105 mtrs. ImageImage
At Farm Everglade @EvergladeFarm Luxurious growth of #Covercrop Horse Gram in between 2 years old #Mango trees cultivated under UHDP method. @realJohnKempf @AdvancingEcoAg @CoverCropCoach This is the 4th cover crop variety in a span of 2 years.#Regenerativeagriculture #soilhealth Image
Thick mat of covercrop. #covercrop @EvergladeFarm It has fully arrested the farm's major problems of soil erosion, run off, breaching of almost all the bunds during heavy rains etc. Cover Crops for countless benefits.

THREAD: What happens to #carbon once it's sequestered in soils? How can we lock it in & ensure it doesn't return to the atmosphere as CO2?

Soil scientists use "fractionation" methods for that^. Fractionation tells us about different pools of C-some stay forever & some are quick
Consider it like food for the body.

Some of the energy in your food will get used to build your bones-it stays there & is permanent. Some of the energy gets digested & respired as CO2 when you breathe. Not permanent, but you still need it. & some is intermediate-stored as fat.
In soils, we call the permanent fraction MAOM (minerally associated organic matter). This is the soil C that gets stuck to minerals & stays forever.

The faster fraction is called POM (particulate organic matter). This pool is a lot more dynamic…

The @ciwem webinar on nature-based solutions and the ELMs scheme has begun! I'll live-tweet key points in this thread. #agriculture #elms
First of all, we're hearing from Gareth Morgan from the @SoilAssociation who is going to try discuss whether farming itself can be a nature-based solution #britishfarming
Gareth Morgan: There are lots of land-sparing options (margins/rewilding etc) whereby some areas cease farming whilst other areas are intensified. Gareth argues that this may sometimes be a slightly 'defeatist' approach and that farming should co-evolve with nature.

🚜🌎💚 Land use, #farming & how this impacts on #ClimateChange is under scrutiny

Today, the Committee on Climate Change (@thecccuk) have launched their new Land Use report

What does it say, does it focus on the right things and is it ambitious enough?
@theCCCuk @UKSustain @SoilsAlliance @SusFoodTrust @LandworkersUK @FOLUCoalition @GreenerUK_ @GreenAllianceUK @WCL_News @DefraGovUK @NFUtweets The report comes at a time when #farming, #landuse and its impact on #climatechange is under the spotlight like never before.

This @theCCCuk report will be a major influence on what farmers will be rewarded for doing to adapt to climate change.
Nature must be given equal emphasis in shaping the future of post-#Brexit #farm support, as #farming and #landuse is also the primary driver of global #insect decline and the #biodiversity crash.

Farmers gathering round to learn how to do a slake test from @soilhealthexprt @sectormentor #orfc19 #ORFC19 Image
1) Place a sieve of soil into a bowl of water for 1 min. Floating = lots of air = indication of high organic matter #orfc19 #soilhealth
2) Lift the sieve up and down gently 5 times to break the top and see if it’s breaking apart
