Fertilizers are products that improve the levels of available plant nutrients and/or the chemical and physical properties of soil. An overview is given over the chemical and physical aspects of plant nutrition uptake and soil properties. The different categories of fertilizers are discussed, and special interest is given on production processes and analyses, including storage and transportation as well as environmental, legal, and economic aspects.
