Anion Exchange Capacity Explains Deep Soil Nitrate Accumulation in Brazilian Amazon Croplands Open
Deep tropical soils with net anion exchange capacity can adsorb nitrate and might delay the eutrophication of surface waters that is often associated with many temperate croplands. We investigated anion exchange capacity and soil nitrate p…

Household livelihood diversification in rural Africa Open
Diversification is a common livelihood strategy for rural households in developing countries, with diversification being either a choice or necessity depending on individual household contexts. Using two waves of data (from 2009 and 2011) …

Mitigating sustainability tradeoffs as global fruit and vegetable systems expand to meet dietary recommendations Open
Recent analyses indicate that global fruit and vegetable (F&V) production will need to increase by 50%–150% by 2050 in order to achieve sustainable and healthy diets for 10 billion people. Although global production of F&V has grown by 50%…

Meta‐analysis on the potential for increasing nitrogen losses from intensifying tropical agriculture Open
Fertilized temperate croplands export large amounts of reactive nitrogen (N), which degrades water and air quality and contributes to climate change. Fertilizer use is poised to increase in the tropics, where widespread food insecurity per…

Nitrogen Cycle Patterns During Forest Regrowth in an African Miombo woodland Landscape Open
Tropical dry forests in eastern and southern Africa cover 2.5 × 10 6 km 2 , support wildlife habitat and livelihoods of more than 150 million people, and face threats from land use and climate change. To inform conservation, we need better…

How much SOM is needed for sustainable agriculture? Open
Soil organic matter (SOM) is generally considered the indicator of soil health. It stores nutrients and water to promote plant growth, thus limiting leaching; provides energy for decomposers that increase nutrient availability; and adds st…

Farm management, not soil microbial diversity, controls nutrient loss from smallholder tropical agriculture Open
Tropical smallholder agriculture is undergoing rapid transformation in nutrient cycling pathways as international development efforts strongly promote greater use of mineral fertilizers to increase crop yields. These changes in nutrient av…

Agricultural intensification and the functional capacity of soil microbes on smallholder African farms Open
Summary Fertilization may impact ecosystem processes that sustain agriculture, such as nutrient cycling, by altering the composition of soil microbial communities that regulate such processes. These processes are crucial to low‐input, smal…
