Top processes
Nitrogen cycling
8 steps- Nitrate is not adsorbed by net-negative soil surfaces and moves with drainage water, taking base cations with it
- Most leaching occurs in autumn and winter, when the crop is gone, mineralisation continues and drainage is highest
- Cover or catch crops take up residual nitrate; non-legume cover crops cut leaching by about 70 percent and legume covers by about 40 percent

Living soil system
4 steps- Fresh casts are enriched in ammonium, nitrate, extractable phosphorus and microbial biomass compared with surrounding soil
- Moist, nutrient-rich casts act as hotspots where nitrate reduction raises nitrous oxide and CO2 emission
- Higher mineral N and improved structure raise aboveground plant production by about 25% on average
