摘要：

Method comprises spreading a yellow film, which is produced by breakdown of chlorophyll, over the area to be fertilised. The yellow film is produced in the appendix in fowl as a breakdown prod. of plants. It may be isolated from the faeces. ADVANTAGE - The process lowers nitrogen levels in areas where they have become too high due to over-fertilisation leading to death of soil organisms. The process is economical and ecologically tolerable.
