Nutrient Dynamics And Inventory In Tropical Grassland Ecosystem In Southern India, K. Karunaichamy, Kailash Paliwal
IGC Proceedings (1993-2023)
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 …

The distribution and cycling of minerals in various compartments of the ecosystem form one of the important aspects of ecosystem study. The uptake of nutrients through the root system and their release via litter and root decomposition depends upon a number of factors including the species, growth and stage of maturity. The semi-arid grazing land ecosystem at Madurai has developed under short evolutionary grazing histories and low moisture regimes, in which grazing pressure has had dramatic effects on the plant community and biomass (Karunaichamy 1992). The biological cycle includes circulation of nutrients between soil and biotic communities by the phenomena …
