Item The Effect of Fertilizers, Sulphur and Mulch On East African Tea Soils(1962) Smith, A. N.(I) Data are presented for pH reactions on water and calcium chloride extracts which show that sulphate of ammonia has reduced the pH of the soil to a depth of at least 12 in. (2) Sulphur has reduced the pH to a depth of at least 4 in. (3) Mulch has increased the pH on one experiment to a depth of 24 in., but has had no effect on the pH of the soil on the other experiment. (4) Methods of halting this increase in acidity resulting from the use of sulphate of ammonia are discussed.
