How land management affects the soil and the sky

How land management affects the soil and the sky

Interesting article on experiences on the ground (and in the sky), when changing from open to covered soils:

New evidence and research regarding the impact of soil microbes on the creation of precipitation can be accurately characterized as a game changer in our understanding of what it takes to produce rain across the globe. The immediate question is: What can we do to create favorable situations for this ice-nucleation cycle to occur? The answer resides in managing more acres regeneratively. The evidence presented from Chihuahuan ranchers is both strong and compelling. What they are observing and documenting, is not happenstance or mere correlation. It has occurred far too often and too consistently for that to be the case.

It’s increasingly clear that when it comes to rainmaking (and rain retention) we reap what we sow—in the soil and in the sky.

Characterization of airborne ice-nucleation-active bacteria and bacterial fragments

Characterization of airborne ice-nucleation-active bacteria and bacterial fragments

Let it (possibly) rain: Some bacteria have the unique capacity of synthesising ice-nucleation-active (INA) proteins and exposing them at their outer membrane surface. […] During 14 precipitation events, strains affiliated with the genus Pseudomonas, which are known to carry INA genes, were dominant. A screening for INA properties revealed that ~12% of the cultivable bacteria caused ice formation at ≤-7 °C. They had likely been emitted to the atmosphere from terrestrial surfaces, e.g. by convective transport.
