Land Degradation &Development, EarlyView.ABSTRACT Sustaining soil potassium (K) supply in intensive continuous cropping systems is increasingly challenging because long‐term crop removal often exceeds the natural replenishment capacity of soil K‐bearing minerals, leading to progressive depletion of plant‐available K pools.

Land Degradation &Development, EarlyView.ABSTRACT Long‐term cultivation can improve soil health, but recovery may not follow the same pathway across contrasting soil and climate conditions. A key unresolved question is whether soil health recovery is mainly associated with the release of physical–chemical constraints or with the gradual rebuilding of carbon, microbial biomass, and nutrient ...

Land Degradation &Development, EarlyView.ABSTRACT Deep straw incorporation is widely advocated for enhancing crop yields and improving agroecosystem functions and services. However, how this practice interacts with different fertilization strategies synergistically to influence soil quality and maize productivity remains unclear.

People and Nature, EarlyView.Abstract Volunteers have been involved in nature observations for decades through citizen science initiatives, providing large data sets as well as problem identification that allow a more complete understanding of many natural phenomena. Although communication is a core component in citizen science, the key factors that determine its effectiveness in ...

Development of the Ligule in Zea Mays L [PDF]
Nature, 1941 DURING an investigation of leaf initiation and apical organization in grasses, some particularly clear stages in the origin of the ligule were seen in young leaves of maize shoots cut longitudinally in the plane of the leaves. The development of the grass ligule has received attention from only a very limited number of workers (Bugnon1,2, Ponzo3 ...

People and Nature, EarlyView.Abstract Urban environments create unique challenges for wildlife, where dietary habits may reflect both ecological heterogeneity and societal disparities. In this study, we explored how social factors such as household income and human population density, and ecological factors such as tree canopy correlate with coyote (Canis latrans) diets in Seattle,

, 2017 From its origins in Mexico, maize has spread throughout the cropping world and now has the largest annual production of any cereal crop. Maize adapted to the tropics has a shorter breeding history than its temperate equivalent, and maize yields in the tropics average 46% those of temperate regions.
