How a small area of ground can support multiple plant species with similar resource requirements is a question that has challenged ecologists for many decades. The Long Term Experiments at Rothamsted Research are a unique resource for studying this kind of question because the plant communities on the plots have had over 170 years to adapt to the different fertiliser treatments and are now relatively stable.
In the world’s driest rainfed wheat region, Washington State University researchers have identified summer fallow management practices that can make all the difference for farmers, water and soil conservation, and air quality.
