How Cover Crops Help Reduce Overaeration Risks
Overaeration drains soil carbon, shatters aggregates, and stalls yield. Cover crops reverse the damage by tightening pore architecture, feeding microbes, and buffering oxygen spikes. They are living insurance against the hidden cost of too much air. Farmers who seed them after every main crop report 30–40 % less nitrous-oxide flux and 0.3 Mg ha⁻¹ more…
