Abstract
A study was made of the responses of four upland soil‐ and vegetation‐types to applied lime and phosphate in the north of Scotland. Light and heavy dressings were used, the former at a rate which might be economically considered for aircraft application. Two experiments were laid down on graminaceous communities and two on contrasting types of Callunetum. The low rate of lime produced little measurable soil response, whereas the high rate induced marked and persistent effects. In terms of botanical response, however, the high rate of liming showed little advantage over the low rate in the presence of phosphate at the two grassland sites. Only very minor vegetation effects were observed at the Calluna centres, particularly where the community was in the mature stage. The results emphasize the importance of an ecological approach to upland pasture improvement, involving a knowledge of the specific responses of different plant communities to fertilizer application, combined with an appropriate measure of stock control.
