Title: Changes in soil properties following a 40- and 20-years application of organic waste
Abstract: Soils of Kuwait contain little plant nutrients and organic matters to support plant growth and development. Soils water holding capacities are very small and need continuous irrigation to maintain water availability. Addition of organic matter in various soils of Kuwait in different time duration were observed and investigated. The effect of organic matter on soil physical and chemical properties were analysed and compared within the soil solution. High variation of macro and micronutrients were distinguished among different soil treatments with organic matter application. Plant nutrients increased in the soil solution with organic matter application enormously. Soil physical properties improved by the decreasing of soils bulk densities and increasing soil water holding capacities. Organic materials are available from many sources in Kuwait, mostly from animal, industrial and municipal waste. These materials can be utilized more efficiently for soil improvement and plants production. Most of organic materials in Kuwait are buried for disposal in limited and very expensive land. Converting organic materials to soils conditioners and fertilizer will improve soil capabilities and save the limited water resources available for irrigation.
