This Agrodok discusses green manuring and several other forms of soil improvement in the tropics. In particular, we shall pay attention to plants that can fix atmospheric nitrogen: the legumes. Due to this capacity these plants do not require nitrogen fertilization, which makes them very suitable for areas where the soild contains little nitrogen. There are many such areas in the tropics where a lack of nitrogen limits the yield of a crop. Chemical manure is not yet easily available in all places, or often too expensive for farmers. In such cases we can grow these nitrogen fixing plants and/or use them as a fertilizer for other crops that reuire nitrogen but cannot fix it themselves.
