Publisher's Synopsis
This volume concentrates on the energy involved in plant nutrition and pest control for crop production. Fossil fuel energy used to produce fertilizers and pesticides is evaluated along with the amount, distribution and use of these fertilizers and pesticides throughout the world. Alternatives to the use of chemical fertilizers and pesticides, and specifically biological nitrogen fixation and the use of organic wastes are discussed in relation to their economic and energy replacement value. Methods for the conservation of nutrients and pesticides are considered. Finally, the energy balance of nutrients and pest control is reviewed in the light of the economic, policy and social issues of the alternative needs and uses.
