Planetary boundaries for terrestrial inputs of reactive nitrogen (Nr) are transgressed and
reducing the input of new Nr and its environmental impacts are major global challenges …

The demand for nitrogen (N) for crop production increased rapidly from the middle of the
twentieth century and is predicted to at least double by 2050 to satisfy the on-going …

World population is projected to reach over nine billion by the year 2050, and ensuring food
security while mitigating environmental impacts represents a major agricultural challenge …

Intercropping is the simultaneous cultivation of plant species in the same field for a
considerable proportion of their growing periods. Interest in intercropping for sustainable …

Grain legumes play a key role in smallholder farming systems in sub-Saharan Africa (SSA),
in relation to food and nutrition security and income generation. Moreover, because of their …

We conducted a systematic review of literature on the residual effects of grain legumes in
cereal-based systems of sub-Saharan Africa (SSA) to quantify the magnitude and variability …

Nitrogen is the most limiting nutrient in most agro-ecosystems and thus critical for sustaining
high yields. Conventional agricultural practices use synthetic fertilizers to ensure an …

Intercropping existed early in the evolution of agriculture. However, for several decades, use
of this sustainable cropping system approach remained limited to small operations in …

Background The demand for estimates of biological nitrogen (N) fixation inputs in
agricultural systems is driven by the need to effectively manage the global N cycle. Scope …

Arbuscular mycorrhizal fungi (AMF) can play a key role in natural and agricultural
ecosystems affecting plant nutrition, soil biological activity and modifying the availability of …
