The Effect of Summer Cover Cropping on Soil Health Is Limited by the Quantity of Carbon Inputs in a Winter Dominant Low Rainfall Environment

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT The effects of summer cover crops on cash crop yields and soil health in semi‐arid cropping systems in southern Australia remain largely unexplored. A study was conducted in Western Australia to investigate cover crop impacts on soil carbon and nitrogen cycling, soil water, and mineral nitrogen (N) and cash crop yield.

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 ...

Evaluating the Adapt‐N model for dynamic nitrogen recommendation in Brazilian maize (Zea mays L.) systems

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Several nitrogen rate recommendation methods have been developed to help farmers fertilize close to the economic optimum N rate (EONR). The objectives of this study were to (i) evaluate a dynamic method (Adapt‐N) for N rate recommendations for maize (Zea mays L.) in Brazil relative to EONRs determined specifically for each trial and (ii ...

Preliminary Functional Group Patterns of Arthropods in a Maize Field and Adjacent Cultivated Refuge Strip in South Africa

Austral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT Agricultural intensification is a major driver of global arthropod declines. Habitat management strategies, such as cultivated refuge strips (CRS), can counteract these effects by enhancing biodiversity, promoting conservation biological control and improving agroecosystem resilience.
