Nitrogen is a problem because most forms are soluble in water and soon leach from the sands. Some of these forms wouldbe nitrates ammoniacals and ureas, as well as most nitrogen mixes and blends. For an effective program, these have to be applied frequent- ly. Once the turfgrass is estab- lished, a 1/2 lb. per growing month gives very good sod.

Get priceThe colour of the dunes in the southern Kalahari can be attributed to the high iron oxide content of the sand. In areas of higher rainfall and in shallow areas where water collects, the iron oxide is leached out, causing the sand ultimately to turn white. The gradual effect of the leaching transforms the desert into a wonderful variety of colours.
