Nutrient status of coffee soils in South India and its influence on crop yields
The nutrient status of the different coffee zones in South India and that of the locations constituting these zones were studied. The level of nutrients varied from zone to zone and from location to location within each zone. The highest level of available nutrients and the lowest acidity were seen in Coorg Zone while poorest soils with respect to its nutrient status and the maximum acidity were met with in Kalpetta Zone. Since 1961 the nutrient status of soils had increased considerably, the maximum shift being in phosphoric acid status and soil reaction. Crop yields also showed as contrasting a picture as the nutrient status. High yield was generally associated with higher nutrient status particularly higher level of available phosphoric acid. Adoption of recommendations prescribed based on the relevant factors including the nutrient status as revealed by soil tests, enhanced the yield in many of the estates studied. In a few cases, wide fluctuations in crop during alternate years could be evened up to a considerable extent
