Summary
The use of a closed system to measure the loss of nitrogen by volatilisation from urea applied to soil has resulted in very high values. The experimental unit described in this paper uses a modified aerated system which gives results in close agreement with yield data. These results, obtained under laboratory and fields conditions, are discussed.
