Soil Conservation
Soil Conservation is a scholarly work, published in 1948 in ''Nature''. The main subjects of the publication include People's Republic of China, rest, soil conservation, soil erosion, geography, appeal, political science, and agriculture. The authors of the booklet admit that "much attention has been given to China and the United States of America" ; but it would be more accurate to say that the United States gets 75 per cent of the space, China 10 per cent, and the rest of the world 15 per cent.
