Geology

Our farm is located near Avebury, on silty clay loam sitting over a seem of grey (lower) chalk. Man's land, certainly not boys' land. In the past, if turned over when wet this soil would quickly turn to concrete. Dryer years have usually been better years as rainfall is still sufficient in dry years for a good cereal harvest.

Grey Chalk Subgroup - Chalk. Sedimentary Bedrock formed approximately 94 to 100 million years ago in the Cretaceous Period. Local environment previously dominated by warm chalk seas. These rocks were formed in warm shallow 'Chalk' shelf seas with little sediment input from land. They often consist of a calcareous ooze of the microscopic remains of plankton.
