Putting farm by-products through a fish pond is the most effective way to recycle farm wastes. The pond becomes the fertilizer factory and the pond mud the fertilizer. Crops fertilized with pond mud, rather than composted crop material, give better and more reliable yields. Researchers from The International Centre for Living Aquatic Resources Management (ICLARM) have been working in Ghana with the Institute of Aquatic Biology and the Ghana Rural Reconstruction Movement. They have found that a fish pond has two roles. It produces fish for the family, and functions as a recycling factory. The latter role is assuming greater Importance as fertilizers get beyond the financial reach of farmers, and land becomes degraded and in need of organic matter. Key to the system is managing the water resources. Rainfall is kept on the farm, instead of running-off and causing erosion as it goes. Soil conservation techniques forces it to infiltrate into the soil, with the excess being channelled into a pond. The pond is stocked with fish which are fed on the crop wastes. In the dry period water is used to grow vegetables on the banks of the pond and mud is used to fertilize the crops. Surplus vegetables are now being sold for cash.
