We grow several different crops in a fairly loose rotation.
Winter barley suits us quite well as does wheat because it results in an earlier harvest. We rely on contract harvesting so avoiding the period of peak demand when the spring malting barley is being harvested is a good idea. The downside is that we get less than we would for malting barley. We also sometimes let part of the arable ground for seed potato growing, a thriving local business carried out by specialists. To maintain a high level of health in the seed potatos, the crop is only grown every seven years or so in any one field.
Growing grain crops combines very well with cattle and sheep farming as it produces quantities of straw for bedding and feed, and part loads of grain can be used up economically as feed.
