Description |
An investigation was undertaken to study the available micronutrient status, fixation of zinc and iron, and to ascertain the effect of various soil properties on the availability of the micronutrients viz., zinc, iron, copper and manganese in turmeric (Curcuma longa L.) growing soils of Guntur District. The soils collected from all the eight mandals representing the entire turmeric growing area of the district were found to be normal in reaction, non-saline, low in available nitrogen, high in available phosphorus and potassium. The soils were high in calcium carbonate content and cation exchange capacity. The most dominant exchangeable cation was calcium followed by magnesium, sodium and potassium. Available zinc and iron were found to be deficient in 57 and 82 per cent of the soil samples respectively. However, no soil sample was found to be deficient in either copper or manganese. Available zinc, iron, copper and manganese contents of the soils exhibited a significant negative correlation with calcium carbonate, cation exchange capacity and clay content. Available manganese and copper . H showed a significant positive correlation with p and organic carbon, while no such relationship was observed with available zinc and iron. Extent of fixation- of zinc and iron continued to increase steadily and thereafter the process tended to become less responsive of the amount added. Zinc and iron fixation were found to be significantly and positively correlated with cation exchange capacity, clay and calcium carbonate contents of the soils. |
