Field Measurement of Soil Erosion and Runoff (FAO Soils Bulletin, No. 68.)
Historically, research on the methods and amounts of trace element application to agriculture soils for correcting plant deficiencies has received major attention. More recently, due to industrial development and past disposal activities, trace elements are considered to be important environmental contaminants that affect all components in the atmosphere and in aquatic and terrestrial systems. Prepared by a multi-disciplinary group of scientists, Trace Elements in Soil: Bioavailability, Flux, an...

Corn Crop Production
Corn or maize is a crop that originated in Mexico and has spread all over the world as a major food crop. Sustainable production of a corn field crop as grain corn for feed, food and biofuels, as well as sweet corn for fresh market or processing, and as silage for high energy sources, requires scientific management of nutrients along with several other crop management practices such as proper plant population density, timely seeding and harvesting, soil water, weeds and pests control. Corn has b...
Covering much of the Earth's surface is a fragile skin of soil, vital to the growth and development of nearly all terrestrial life. Today, as we attempt to satisfy the growing needs of modern societies, the world's soils are placed under ever increasing risk from erosion, pollution, and loss of biodiversity, but many of us don't even understand how soil functions or what we can do to help preserve it. This work offers a practical introduction to soils. It covers everything from how it is formed,...
Optimizing productivity of food crop genotypes in low nutrient soils (IAEA-TECDOC, #1721)
Global climate change and variability are likely to exacerbate plant abiotic stress in the coming decades by increasing water stress and by accelerating soil fertility degradation. To respond to this set of challenges, there is a need to develop agricultural systems with significantly greater productivity and resilience, while at the same time making more efficient use of limited nutrient resources. This publication summarizes the results from a FAO/IAEA coordinated research project (CRP) on opt...
Past and Present Soil Erosion (Oxbow Monographs in Archaeology, #22)
These twenty papers are based on a meeting at the Institute of Archaeology, London in May, 1991. They fall into four categories: Lowland Britain: Linking archaeology and geomorphology (John Boardman and Martin Bell), South Downs (John Boardman), Prehistory (Martin Bell), Prehistoric land-use of the Wessex Chalk (Michael J Allen), England and Wales (R Evans), Woburn Experimental Farm, Beds. (J A Catt), The floodplain edge (A G Brown), The Slapton catchment, Devon (Louise Heathwaite and Tim Burt);...

Non-First Order Degradation and Time-Dependent Sorption of Organic Chemicals in Soil (ACS Symposium)
Pesticides are essential tools for crop protection and disease prevention. These agricultural chemicals (and their associated uses) continue to be subject to increased regulatory scrutiny, even though modern pesticides have become safer, more effective, and target specific. Pesticide persistence, off-target movement to ground and surface water systems, and potential for impacting non-target organisms are the major focus for regulatory assessments. Sorption and degradation are among the dominant...
