grown under full sunlight for photosynthesis. * Soil type: Cassava can be grown on most soils; however the best soils are sandy clay loams that are well drained without a fluctuating water table. Proper soil management practices‚ adequate soil drainage and limestone applications at 2-4 t/ha incorporated into the soil 3 to 4 months before planting are necessary for the successful cultivation of cassava in the following "sugarcane" soils: Washington Series‚ Waterloo Series‚ Couva Series‚ Freeport

to the soil helps produce healthier‚ more abundant crops; such a substance is called fertilizer. The researchers decided to make an organic fertilizer. Organic fertilizers are made up of organic materials such as leaves decay‚ they produce an excellent fertilizer. Fertilizers are also often by-products of some manufacturing process. Some organic fertilizers are waste products of living organisms. They also supply food for beneficial bacteria in the soil and improve the condition of the soil. They
