Notes:
1Rate of growth expressed as percentage increase in total nutrient demand compared with previous year.
2This rate of growth is misleading as the market demand was subject to wide fluctuations, e.g. the total demand for 1972/73 and 1973/74 was 152,937 tons and 151,028 tonnes of Potassium and 90,330 tons and 84,306 tonnes of Phosphorus respectively.
3All figures are quoted as tonnes of nutrient Nitrogen (N), Phosphorus (P) and Potassium (K).
