Soil heat flux measurements were made in black Cotton soil in a bare plot and a jowar fied, at Pune, using Thornthwaite heat flow discs. The reversal of sign of heat flux is delayed in the morning by about 45 min. and is advanced by about 30 min. in the late afternoon in the crop field. The net daily heat flux is generally negative in crop field and positive in bare plot.
The share of soil heat flux in day timo energy budget with full crop cover was found to be 4 to 5 per cent of net radiation.
