Theme 04: Soil Fertility and Plant Nutrition
Description
The present study was to ascertain the distribution of calcium (Ca), magnesium (Mg) and sodium (Na) in the different plant components and in the soil top 30 cm at Kalikesam in Western Ghats region of southern India. Magnesium concentration increased in the order: dead shoots > belowground > litter > aboveground live. Sodium concentration in live shoots was maximum in February (0.51%) and minimum in August (0.05%). Annually 8.94 g/m2 Ca, 2.41g/ m2 Mg and 2.30g/ m2 Na was taken up by plants. The distribution of the three nutrients in plant/soil system indicated that the major portion of the nutrients in the system was retained in the soil, while small fraction of it stayed in plant components. Less than 0.4% of Mg entered the vegetation. Ca and Na entered 16% and 6% respectively.
