Cover Crops Enhance Aboveground Biomass, Soil Biological Activity and Soil Organic Carbon in Tropical Agroecosystems

Soil Use and Management, Volume 42, Issue 3, July‐September 2026.
ABSTRACT In tropical agroecosystems, soil organic carbon (SOC) accrual is constrained by rapid organic matter turnover and seasonal water limitation. Cover crops are widely used to improve soil C inputs, but their effects on SOC fractions and soil biological activity can vary according to species composition and management duration.

Response of cereals to intercropping with non‐food crops in tropical and subtropical regions: A meta‐analysis

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Intercropping cereals with non‐food intercrops (NFICs) provides a means to enhance cereal productivity while providing additional benefits such as improved soil health or forage production. We conducted a meta‐analysis to investigate the effect of NFICs on cereal yields, cereal nitrogen uptake, and striga (Striga spp.) infestation, using 874 ...
