Biological dinitrogen (N 2) fixation is a natural process of significant importance in world
agriculture. The demand for accurate determinations of global inputs of biologically-fixed …

The soil environment is one of the main places for the generation, emission, and absorption
of various atmospheric pollutants, including nitrogen oxides (NO x) and volatile organic …

The rhizosphere is a complex environment where roots interact with physical, chemical and
biological properties of soil. Structural and functional characteristics of roots contribute to …

Nitrogen (N) tends to limit plant productivity on young soils; phosphorus (P) becomes
increasingly limiting in ancient soils because it gradually disappears through leaching and …

Soil micro‐organisms play a key role in soil biogeochemical cycles, but their growth and
activities are often limited by resource availability. Understanding soil processes that are …

Walnut anthracnose caused by Colletotrichum gloeosporioides is a deleterious disease that
severely affects the production of walnut (Juglans regia L.). The aim of this study was to …

Arid ecosystems cover∼ 40% of the Earth's terrestrial surface and store a high proportion of
the global nitrogen (N) pool. They are low-productivity, low-biomass, and polyextreme …

We review the current state of knowledge of quantified impacts of invasive alien plants on
water quality, with a focus on South Africa. In South Africa, over 200 introduced plant species …

By improving fertilization, irrigation and crop cultivation managements, rice yield and N
efficiency can be increased to some extent. However, the environmental impacts under …

The balance of C, N, and P in plants, soil, and microbes is remarkably important for
maintaining forest ecosystem stability. However, during forest transitions, the potential …
