One-sixth of the planet's cropland has toxic levels of one or more metals (elpais.com)
The first 30 centimeters of soil are the foundation of life. This foot-deep slice of the pedosphere is the vital space for most plant roots. When roots go deeper, it’s to anchor the plant, not to nourish it. Within this narrow band, bacteria, fungi, nematodes, and countless other microscopic organisms form the so-called biological crust, which in turn supports the larger life forms above.
There Is One Clear Winner in the Corn vs. Solar Battle (cleantechnica.com)
“Solar energy is often framed as a threat to croplands. However, vast croplands in the Midwestern United States already support corn ethanol biofuel, a form of energy with a greater land-use footprint per unit energy (~30×) and potential environmental impact (e.g., excessive fertilizer application) than solar energy. We envisioned sustainable agro-ecosystems that can result from converting a small proportion of corn ethanol croplands into ecologically informed solar facilities (i.e., ecovoltaics).

DIY experimental reactor harnesses the Birkeland-Eyde process (arduino.cc)
Nitrogen is critical for farming at scale and without some form of nitrogen to enrich the soil, we couldn’t grow staple crops efficiently enough to feed our large global population. Serious science goes into the production of fertilizers and the Birkeland-Eyde process was one early example. It uses electrical arcs to turn nitrogen in the air into nitric acid. Marb is an enthusiastic citizen scientist and built his own experimental reactor to harness the Birkeland-Eyde process.
