Effect of mulches on nutrient uptake of Albizia procera and subsequent nutrient enrichment of coal mine overburden. Nutrient concentration and accumulation of Albizia procera grown for one year inb pots under the influence of different mulches (control stones/gravels husks leaf litter and grasses) were studied and subsequent nutrient enrichment of the soils was estimated. The substrate used for growing Albizia procera as test crop was a mixture of coal mine overburden and compost in 1:1 proportion (V/V). Against increases of biomass by 128.6 116.8 113.8 and 79.9 per cent over the control due to application of husks leaf litter grasses and stones/gravels respectively there were increases of 317.2 210.9 198.5 and 123.1 per cent in total accumulation of nutrients which constituted 4.83 3.8 3.69 and 3.28 per cent of the total biomass. The total nutrient content of the control (1.79 g plant-supesrcript 1) contributed only 2.65 per cent to the total biomass. Appreciable increases in available nutrient status (N P K) CEC and exchangeable cations in the soils were also observed due to application of mulches with the maximum value given by husk mulch followed by grasses leaf-litter and stones/gravels. These mulches should be used in afforesting mine overburdens for better growth biomass production and nutrient uptake.

Abstract

Effect of mulches on nutrient uptake of Albizia procera and subsequent nutrient enrichment of coal mine overburden. Nutrient concentration and accumulation of Albizia procera grown for one year inb pots under the influence of different mulches (control stones/gravels husks leaf litter and grasses) were studied and subsequent nutrient enrichment of the soils was estimated. The substrate used for growing Albizia procera as test crop was a mixture of coal mine overburden and compost in 1:1 proportion (V/V). Against increases of biomass by 128.6 116.8 113.8 and 79.9 per cent over the control due to application of husks leaf litter grasses and stones/gravels respectively there were increases of 317.2 210.9 198.5 and 123.1 per cent in total accumulation of nutrients which constituted 4.83 3.8 3.69 and 3.28 per cent of the total biomass. The total nutrient content of the control (1.79 g plant-supesrcript 1) contributed only 2.65 per cent to the total biomass. Appreciable increases in available nutrient status (N P K) CEC and exchangeable cations in the soils were also observed due to application of mulches with the maximum value given by husk mulch followed by grasses leaf-litter and stones/gravels. These mulches should be used in afforesting mine overburdens for better growth biomass production and nutrient uptake.
