Answers
Answer:
Red sandy loam, laterite and alluvial soils are suitable. Select sites with deep (not less than 1.5 m depth) well drained soil heavy, imperfectly drained soil is unsuitable. Avoid shallow soils with underlying hard rock, low-lying areas subject to water stagnation and heavy clayey soils. Soil with a minimum depth of 1.2 m and fairly good water holding capacity is preferred for coconut cultivation. However, in lands, reclaimed by heaping alternate layers of sand and clay, coconut thrives well. Proper supply of moisture either through well distributed rainfall or irrigation and sufficient drainage are essential for coconut. Coconut can be grown in soil with pH of 5.2 – 8.6.

Preparation of Land
The nature of preparation of land before planting depends upon topography of land, soil type and other environmental factors. The area should be cleaned and planting holes marked out at appropriate places. If the land is slopy, soil conservation methods should be adopted. If the groundwater level is high planting may be taken up in the mounds. On slopes and in areas of undulating terrain, prepare the land by contour terracing or bunding. In low-lying areas and rice fields, form mounds to a height of at least 1 m above water level. In reclaimed kayal areas, planting can be done on the field bunds.

Field Layout
Although several systems of planting are followed, selection of a suitable system depending on soil, climate, plant type etc. Adoption of improper system results in over lapping of plant parts, competition for water, light, nutrient and unequal distribution of water etc., ultimately results I poor performance.
The systems of layout are Square system, Rectangular system, Triangular system, Hedge system and Contour system. These are all systems are followed in Tamil Nadu, Kerala and Karnataka state.
