Determining the nutrient deficiencies of soils is one of the m~ost important of agronomic problems. The success of the farmer, the economical and intelligent use of fertilizers, and, in fact, a continued adequate food supply depend to a considerable extent upon how readily soil deficiencies can be-recognized and how efficiently such information can be utilized. Numerous methods have been proposed for estimating the nutrient deficiencies of soils. There are the chemical methods, the micro-biological methods, the vegetation pots methods, and the field plat methods.
