Toward greater sustainability: how investing in soil health may enhance maize... N3 | TTL | RDF/XML | JSON-LD
CIMMYT EthiopiaClimate change and soil fertility decline are major threats to smallholder farmers' food and nutrition security in southern Africa, and cropping systems that improve soil health are needed to address these challenges. Cropping systems that invest in soil organic matter, such as no-tillage (NT) with crop residue retention, have been proposed as potential...Created January 20, 2025 • Updated January 20, 2025 -
