This volume focuses on reclamation, management, and utilization of salt-affected soils, their sustainable use, and evaluation of plants inhabiting naturally occurring saline habitats. It is of interest to scientists and students as well as agricultural institutions and farmers to increase the awareness of salinity problems. The volume is supported by UNESCO Doha, Qatar, and has an international authorship.

Bemisia tabaci (Gennedius) has distinguished itself from the more than 1,000 whitefly species in the world by its adaptability, persistence and potential to damage a wide range of agricultural and horticultural crops in all six of the world s inhabited continents. B. tabaci inflicts plant damage through direct feeding, inducement of plant disorders, vectoring of plant viruses and excretion of honeydew. This book collates multiple aspects of the pest ranging from basic to applied science and molecular to landscape levels of investigation. Experts in multiple disciplines provide broad, but...

Time-variable exposure profiles of pesticides are more often the rule than exception in the surface waters of agricultural landscapes. There is, therefore, a need to adequately address the uncertainties arising from time-variable exposure profiles in the aquatic risk assessment procedure for pesticides.

Linking Aquatic Exposure and Effects: Risk Assessment of Pesticides provides guidance and recommendations for linking aquatic exposure and ecotoxicological effects in the environmental assessment of agricultural pesticides. Leading international scientists share...

In this practical and helpful manual, John R. Weir, who has conducted more than 720 burns in four states, offers a step-by-step guide to the systematic...

Beyond the Biophysical provides a broad overview of agriculture and natural resource management (NRM) scholarship and practice that lies beyond the biophysical, emphasizing instead epistemological, cultural, and political foundations of NRM. The volume is oriented toward professionals with expertise in agriculture and natural resource management scholarship and practice, but who lack exposure to the conceptual and methodological underpinnings of critical theory, the anthropology of development, ecological anthropology, and other relevant scholarship. It therefore follows common...

The author, an experienced farmer, takes a down-to-earth approach to agriculture. Based on an example farm of around sixty hectares (or about 150 acres), he recommends the ideal livestock numbers: twelve cows, four horses, six pigs, ten sheep and 120 hens. This mix is drawn from Osthaus's deep understanding of nature, animals, agriculture and the cosmos, and...
