GREEN CROPPING
The sowing of blue lupin for digging in has been mentioned in these notes lately. The problem of maintaining an adequate supply of humus in ground devoted to intensive cropping is very pressing; in the absence of a sufficient supply of farm or stable manure, growing green cover crops is the main alternative. As a generous supply of humus is a fundamental necessity, land should not be left bare after harvesting, but lightly cultivated and sown down at once with blue lupin, mustard, oats, barley, beans, or any crop which will make rapid growth at the season and during the time the land can be spared for the purpose. Green cropping is an excellent method of smothering out weeds which, we are now beginning to learn, are responsible for many more injurious effects on crops than merely that of competition with which they are generally charged. As hosts for insect pests and many plant diseases, some of them carry over the trouble from year to year when it would otherwise die. out, or they are the source of contagion that is easily overlooked. When sowing the green crop, give a liberal sprinkling of superphosphate to encourage rapid and luxuriant growth.
