Manure and crop residues raised yields in long-term rice–wheat trials

Long-term trials in Bihar, India, found that manure and crop residues improved soil properties and raised rice and wheat yields. Reduced tillage mainly benefited physical soil conditions, but zero-tillage results varied by site and could lower yields when residues were not added.

Sun angle and rough soil, not wetness, drive changing satellite soil colors

Satellite images often average bare-soil data over long periods, but the colors can change even under similar conditions. Using seven years of Landsat 8 and Sentinel-2 reflectance data from more than 27,000 European sites, researchers found that changes in solar angle interacting with rough bare soil explain most of the temporal variation, while surface moisture contributes less.
