In Agricultral Statistics, United Kingdom, 1974, the area of land devoted to vegetables grown in the open for human consumption is given as 187 500 ha. This amounted to some 4% of the tillage land in the UK, and along with similar areas of sugar beet and maincrop potatoes would appear to offer significant scope for the utilization of associated by-products as feed for livestock. The range of such crops produced in the UK is quite wide, but climatic and market pressures will influence actual cropping from year to year. Relevant details for the United Kingdom are set out in Table 1, and it will be seen that in 1974 England and Wales accounted for 95, 78 and 100%, respectively, of the areas of outdoor vegetables, maincrop potatoes and sugar beet grown in the UK. In the following, therefore, the discussion will be concentrated on the problems of production and distribution of vegetable and arable by-products. Similar problems of distribution will no doubt occur in other countries as well.
