Extract

The effect of subsoiling an old arable clay-loam soil at Broom's Barn Experimental Station, Suffolk, was tested with a sequence of wheat, barley and sugar-beet crops, a lucerne ley and a sugar-beet test crop in the fourth year.

Subsoiling increased the yield of each crop each year, averages over 3 years were: wheat, 0·6 cwt/acre of grain; barley 0·4 cwt/acre; lucerne 0·6 cwt/acre of dry matter. Average increases of sugar beet over 4 years were 0·7 tons/acre of roots or 2·1 cwt/acre of sugar; the increase was greatest (2·9 cwt/acre of sugar) in the first year.
