When areas of land larger than 8 ha (20 acres) are being evaluated for pineapple planting, a soil survey should be conducted. A survey will provide important information regarding the topography, soil profile and subsurface variations in soil structure, soil chemistry and drainage. This information will be vital in determining the need for contouring and other erosion-control measures, surface drainage, subsoiling, depth of cultivation, need for bed formation, nutrient requirements and other cultural practices that can be influenced by soil conditions.
The surveys should be conducted by a person familiar with standard survey procedures, including site preparation and soil classification. The survey reports should include any history of past usage, including cropping and soil management. The physical description of the soil by profile should be supplemented with information on physical and chemical analyses to allow appropriate agricultural practices to be developed.
Maps should be prepared that identify boundaries of the growing areas, areas particularly susceptible to erosion, waterways and other drainage channels, roads and pathways, particularly if these are used by the public. The approximate boundaries of each soil type should be identified according to soil classification. All of this information should overlay a topographical map of the area to facilitate development of field layout and drainage systems.
Residential and other environmentally sensitive areas should be identified to facilitate compliance with local regulations.
