After war work on delayed action detonators, Nye joined the British Colonial Service, and in 1947 was sent to the Gold Coast (now
Ghana) as an Agricultural Officer. Following a year at the
International Atomic Energy Agency in Vienna, Nye was a appointed
Reader in Soil Science at the
University of Oxford from 1961 to 1988, becoming a founding Fellow of
St Cross College, Oxford. In Oxford, Nye pioneered mathematical modelling of the complex chemical interactions between plant roots and solutes in the surrounding soil. The resultant book, with P.B. Tinker,
Solute movement in the soil-root system (1977, 2nd edn. 2000) is said to be "one of the most influential books across the whole of plant and soil sciences". ==Personal life==
