catch crop,

Put simply, if you plant a crop such a leeks in May or June, that start life as small, thin, insignificant plantlets, spaced quite widely to allow for a long growing season, the gaps between the rows will not be filled in until late August, giving you up to three months to use the unplanted land to grow catch crops of rocket, radish, lettuce and other fast growing salads, whilst the leeks chug along slowly in the background.
Catch crops are also great for nutrient management, Guggenberger said, reducing the need for mineral fertilizers that deplete soils' humus content, introduce toxins into the food chain and release greenhouses gases like nitrous oxide.
