In the arid landscapes of Tunisia’s Bou Hedma National Park, a silent battle is unfolding—not between armies, but between shifting climates and an ancient tree species that has stood its ground for centuries. Vachellia tortilis, a hardy acacia known

Clovis Field Day showcases cover crops, biochar, compost, perennial buffer strips and algae trials.

This week on iGrow Digest: Holtec, Franklin Electric, Mitti Labs. Two reactor developers hit the public markets in the same week — and the largest farmland carbon deal ever disclosed landed in Kazakhstan. The post Agreena signed a 4.45 million-tonne soil-carbon deal across 1.6 million hectares in Kazakhstan appeared first on iGrow News .

This week on AgTech Digest: Agreena, Mitti Labs, Bayer. Agricultural carbon just stopped being a pilot project: two record offtakes landed in the same week, one of them 4.45 million tonnes. The post The largest farm carbon deal ever signed covers 4.45 million tonnes across Kazakhstan appeared first on iGrow News .

By burying thousands of pairs of cotton underwear across Switzerland, scientists uncovered striking differences in biological activity from one type of land to another. The results showed that gardens had especially active soils, while lawns were much quieter underground. Soil supports the global food system while also storing water, carbon, and essential nutrients. It is [...]

Prescribed fires, associated to extensive cattle raising, and the expansion of crop agriculture are two of the main threats to the integrity and functionality of páramo ecosystems in the Northern Andes. In addition to affecting plant and animal communities, these practices could significantly affect soil carbon storage and hydrological regulation. In this study, we present results from a field ex…

The rational application of potassium (K) is essential for soil nutrient transformation in orchards. Microbial communities drive phosphorus (P) transformation and activation, yet their responses to potassium (K) gradients and the underlying regulation of functional potential remain unclear. Accordingly, a field trial was conducted on 7- to 8-year-old Korla pear trees to evaluate changes in microb…

Researchers in Taiwan have developed a new way to model how beneficial microbes move through soil—a breakthrough that could help farmers get more value from biological crop treatments. The team, led by Shuai Yuan at National Taiwan University, built

In the shadow of industrial sites, where soil often bears the scars of pollution, a quiet revolution is taking root. Researchers at the Centre of Excellence in Technology Solutions for Soil and Water Remediation (TSSR) at the Jaypee Institute of Info

Nature Geoscience, Published online: 10 September 2026; doi:10.1038/s41561-026-02082-2 Our global analysis of multi-source, multilayer soil moisture datasets shows that droughts become particularly damaging when moisture deficits occur simultaneously throughout the soil profile, eliminating vertical hydrological buffering. These vertically compound droughts have intensified across much of the glo…

IntroductionSpent mushroom substrate (SMS) is a major residual stream from edible mushroom production and a potential feedstock for organic fertilizer. Although earthworm composting can alter SMS transformation, the microbial processes associated with nitrogen transformation remain poorly resolved.MethodsSeven mixtures of black fungus SMS (AhSMS) and golden needle mushroom SMS (FfSMS) were subjec…

ST. PAUL, Minn. — Drought has defined five of the last six growing seasons in Minnesota, with below-normal precipitation and above-normal temperatures contributing to the spread of D1, D2, and D3 drought conditions across more than 75% of the state this summer. August is normally one of Minnesota’s wettest months, but rainfall totals have continued […] The post What Happens to Soils During a Drou…

FARGO, N.D. — A former North Dakota State University Extension specialist and professor may have retired, but he hasn’t stopped sharing his knowledge of soil with the state. Two years after his retirement from NDSU Extension, Dave Franzen has compiled over five decades of soil fertility expertise into his book, “The North Dakota Soil and […] The post Comprehensive North Dakota Soil and Fertilizer…

LINCOLN, Neb. – Questions about trees, soil health, water quality or cost-share programs? Stop in to visit Nebraska’s Natural Resources Districts during Husker Harvest Days Sept. 15-17, 2026. “This is a great opportunity for producers to meet with conservation agencies all in one place and learn more about cost-share programs that can benefit their operation […] The post Husker Harvest Days Inclu…
