§ Mrs. FennerEstimated changes in fertiliser application rates, based on the annual sample survey of fertiliser practice carried out by MAFF and the Fertiliser Manufacturers Association, have been as follows:
Percentage change in fertiliser application rates Nitrogen Phosphate Potash 1975–76 to 1976–77 + 14.4 -2.6 +5.4 1976–77 to 1977–78 + 2.7 + 5.4 + 2.6 1977–78 to 1978–79 + 6.1 -2.6 0 1978–79 to 1979–80 -1.0 -2.6 0 1979–80 to 1980–81 +8.3 +2.7 +2.5 Between 1975–76 and 1976–77 increases in areas fertilised were estimated to be 6 per cent., 4.4 per cent. and 6.2 per cent. of nitrogen, phosphate and potash respectively. Since that time areas fertilised have remained relatively stable.
Comparable data are not available prior to 1975.76.
