FERTILISING QUALITIES OF BAIN

The fertilising qualities of tropical rainfall are probably not realised by most students of agriculture. Nitric acid is formed in the atmosphere by lightning discharges, and is most abundant in regions where thunderstorms are of frequent occurrence. In the "Anhales de Geographic," M. Guillaiune Capus discusses the results of chemical analyses of rain-water made in French Indo-China, and bases thereon an estimate of the total value of the fertilising substances Jbrought to the soil by rain over a great rice-growing region. In the thirteen provinces constituting the Tonkin delta he estimates that the amount of atmospheric nitrogen thus annually obtained is equivalent to 181,390 tons of nitrate of soda, and 137,510 tons of sulphate of ammonia, worth £3,900,000.
