Field Locations. For each field test location a variety of information is collected and recorded in addition to the samples which are collected. Seven general categories of information can be defined. Three simple ones are 1) test design or plot plan, 2) location and 3) field use history for several years. Field soil characterization 4) includes screen analysis (soil type), pH measurement, and organic matter content. Weather information 5) includes daily temperatures and rainfall and/or irrigations during the test. Application related data 6) consists of dates, application modes, weather conditions at application, calculations and calibrations. Harvest information 7) includes crop name, part, amount, date, and collector.

This chapter presents an overview of reactive absorption, which is one of the most important industrial reactive separation operations. Industrially relevant systems and equipment are highlighted, the modeling basics and peculiarities are detailed, and the methods of model parameter estimation are discussed. Both steady-state and dynamic modeling issues are addressed. The implementation of the theoretical description is illustrated with a number of up-to-date applications and validated against laboratory-, pilot- and industrial-scale experiments.

Uranium-235 decays by alpha emission (half-life = (7.0381 0.0096) X 10 yr Jaffey et al., 1971) to Th, which decays (half-life = 1.06 d) to Pa (half-life = 32,760 220 yr Robert et al., 1969). Because of its short half-life, Th can be ignored for Pa dating applications.
