Fertilizing with inorganic nitrogen and phosphorus definitely improves crop yields, but does it also improve the soil? The latest study to tackle this question has yielded mixed results. While 50 years of inorganic fertilization did increase soil organic carbon stocks in a long-term experiment in western Kansas, the practice seemingly failed to enhance soil aggregate stability–a key indicator of soil structural quality that helps dictate how water moves through soil and soil's...

What happens to the soil when you remove the plants? Crop residues, perennial warm season grasses, and short-rotation woody crops are potential biomass sources for cellulosic ethanol production.

Moreover, effects of crop residue removal on...
