Abstract
Leafy vegetables grown under glass in winter have a rather high nitrate content. Three possibilities of reducing this content are discussed: the use of nitrification inhibitors, growing on NFT and omission of nitrogen during a certain period before harvest, and the breeding of varieties with a low nitrate content.
In the last chapter the question whether high nitrate levels in vegetables are dangerous to human health is briefly discussed.
