Waste-stream materials can be obtained at little or no cost but their value in agriculture is limited by transportation and application costs. To be practical and economic, waste products must be applied on agricultural land which should be located near the production facility. In this study we examine the effects of a wide range of organic amendments on cotton soil and the associated changes due to their application. If application of these materials proves beneficial, it will benefit not only cotton farmers but will also offer an economic and environmentally acceptable means of waste disposal.
