11 SOILS IN ESSEX 111 The latest publication on Essex Soils from the Soil Survey of England and Wales deals with the Little Waltham and Terling district extending from Broomfield in the south- west, across to Nounsley and Hatfield Peverel and north to a line joining the Leighs to the Notleys. This is a rich agricultural district with varied soil types from impermeable loamy over clayey acid soils on level plateaux to chalky clayey alkaline or neutral soils on more undulating terrain and with acid permeable soils on gravels in the valleys of the Chelmer, Ter and Brain. The soil map on a 21/2" to 1 mile base shows in detail the distribution and relationships of these varied and con- trasting soils. An accompanying map at the same scale shows the capability of these soils for agricultural use by grading them from 1 to 4 according to their physical limitations such as wetness. The soils described are widely found overnorthern and central Essex and the des- criptions and analyses quoted in the Record will be of interest to naturalists and agronomists alike. As well as descriptions of the soils and their agricultural potential, the Record also has detailed chapters on physiography and drainage, climate, geology, Pleistocene (Ice Age) and Recent landscape development (including the impact of man on the landscape from Neolithic to mod- ern times) and on the flora of woodland, hedgerows and ponds. There is also a guide to the suitability of the different soils for the planting of native trees and shrubs. The record and maps are available through bookshops, but it is perhaps easier and quicker to order them direct from the Soil Survey of England and Wales at Rothamsted Experimental Station, Harpendon, Hertfordshire, enclosing £3.00 for the book (Record) and two maps or £1.00 for the book alone.
