S ummary .1 The co‐ordination of the available data relating to the environmental conditions of agricultural regions is advocated as a means of facilitating the testing and ultimate distribution of new crop varieties. 2 The physical environment (topographical, geological, climatic and edaphic) of three agricultural regions is described, and its influence on the length of the growing season, the length of crop rotation, and the distribution of the principal crops is discussed. 3 Taking the parish as the unit, maps for the three regions are given to illustrate the mean elevation of cultivated land (Figs, 1 a, b and c ), the estimated accumulated temperatures (Figs. 2 a, b and c ), the mean annual rainfall (Figs. 3 a, b, c and d ), the percentage of farm land under rotation (Figs. 4 a, b and c ) and the length of rotation (Figs. 5 a, b , and c ).
