The Fertilising Influence of Sunlight

Abstract

THE letters on the above subject in NATURE of February 17 and March 3 and 10 are of much interest. In many parts of the world artificial heating of the soil is a regular practice. For example, in the rice districts of heavy rainfall in the Bombay Presidency the seed-bed for transplanted rice and some small millets is almost invariably subjected to a process known in the vernacular as “rab.” This consists of spreading a layer of branches, grass, cow-dung, &c., over the surface of the plot (often only a few metres square) selected as the site of the seed-bed. This material is then slowly burnt before the breaking of the monsoon.
