| Description |
The use of polymers to help establish tree seedlings is being undertaken in Sudan. (The Polymers are plastic soil conditioners that work like sponges, absorbing up to 600 times their own volume of water. Mixed with soil, they release moisture to adjacent plant roots). This programme is being conducted by researchers at Khartoum's Institute of Environment Studies and the UK-based Institute for Terrestrial Ecology (ITE). The polymer is useful in sandy soils which lose water quickly under irrigation or after rainfall. However, the release of the water to the soil cannot be controlled chemically at the moment, although it can be controlled physically. In one experiment in Sudan intermittent rains were stimulated at six-day intervals. Al1 the seedlings that had not been treated with polymer were dead after the first rain but the ones that had been treated had a 70 % survival rata after one month For further information con tact: Dr Terry Calaghan 68 Hills Road Cambridge CB2 ILA GREAT RRITAIN The use of polymers to help establish tree seedlings is being undertaken in Sudan.
