Winter wheat–summer fallow is the conventional cropping system employed on >1·5 million ha within the Columbia Plateau of eastern Washington and northern Oregon. Wind erosion contributes to poor air quality in the region, yet little is known concerning the magnitude of soil and PM10 (particulate matter of ≤10 μm in aerodynamic diameter) loss from agricultural lands. Therefore, loss of soil and ...

In Central Aragón (NE Spain), where strong and dry winds are frequent all year round, fallow lands are susceptible to wind erosion due to insufficient crop residues on the surface and loose, finely divided soils by multiple tillage operations. Effects of conventional tillage (CT — mouldboard ploughing followed by a compacting roller) and reduced tillage (RT — chisel ploughing) on soil surface p...

The ability of agricultural lands to sequester carbon from the atmosphere and help mitigate global warming has the potential to add value to farmland through the development of carbon-credit trading. Crucial to the creation of a market-based carbon credit trading system is the monitoring and verification of agricultural practices that promote carbon storage. Using remotely sensed images for thi...

Several rodent species cause damage in vineyards and orchards. Current efforts to reduce chemicals used to control rodents are encouraging development of alternative practices, such as biological control. For several years growers in California have been installing artificial owl nest boxes to attract barn owls with the hope of reducing rodents, especially gophers, through predation. Effectiven...
