| dc.description.abstract | The present investigations entitled “Carbon appraisal of different land use systems of Srinagar District of Kashmir valley” were carried out at two sites in district Srinagar of Kashmir valley (34o01¢ 08.29² North latitude and 77o47¢ 53.56² East longitude) of Jammu and Kashmir during 2009-10 and 2010-11. Eleven land use systems were selected which are: wasteland/uncultivated land, Agriculture (Rice-Mustard), Agriculture (Rice –oats), Vegetable (Beans-chilli), horticulture (apple only), agri-horticulture (apple-vegetables), agri-silviculture (willow + rice-mustard), plantation forest (willow), plantation forest (Poplar), natural forest (Blue Pine) and grassland. Site A was at an altitude of 1593-2513 m amsl and Site B at 1780-2618 m amsl. All the eleven land use systems were selected at both these altitudinal levels. The plot size in each tree based land use system was 10 m x 10 m and in cropland/agriculture and grassland it was 1m x 1 m. Existing biomass production, carbon stock and carbon sequestration potential (CO2 equivalent) of each land use systems were evaluated. The results have revealed that different land use systems have influence on the production of above ground biomass, below ground biomass as well as total biomass, carbon stock and carbon sequestration potential in both the locations. Maximum above ground biomass (989.743 t ha-1), (931.625 t ha-1) below ground (247.435 t ha-1), (232.906 t ha-1) and total biomass (1237.179 t ha-1), (1164.531 t ha-1) was accumulated in the Natural forest-Blue Pine land use system at site A and B respectively. The minimum biomass was recorded in wasteland/uncultivated land use system (1.949 t ha-1) ,(1.893 t ha-1) at site A and B respectively. Total carbon stocks of different land use systems at site A and B followed the trend : Natural Forest-Blue Pine (556.731 t ha-1), (524.039 t ha-1) > Plantation forest-Poplar (407.703 t ha-1), (383.241 t ha-1) > Agri-silviculture-willow + rice (80.162 t ha-1), (76.092 t ha-1) > Plantation forest-willow (74.498 t ha-1), (70.131 t ha-1) > Agri-horticulture-apple + vegetable-Beans (64.173 t ha-1), (66.150 t ha-1) > horticulture-apple alone (61.630 t ha-1), (64.279 t ha-1) > agriculture-rice-oats (5.047 t ha-1), (4.809 t ha-1) > vegetable-beans-chilli (2.556 t ha-1), (2.507 t ha-1) > agriculture-rice-mustard (2.288 t ha-1), (2.162 t ha-1) > grasslands (1.195 t ha-1), (1.124 t ha-1) > wasteland/uncultivated land (0.877 t ha-1), (0.852 t ha-1) at site A and site B respectively. Similar trends were also seen in carbon sequestration potential of different land use systems. Rate of biomass production at site A (60.4 t ha-1 yr-1) and at site B (53.227 t ha-1 yr-1) was maximum in the Plantation forest-Poplar land use system. The rate of carbon sequestration potential was maximum (99.751 t ha- 1 yr-1) and (87.905 t ha-1) at site A and Site B respectively in plantation forest- Poplar. Land use systems viz. T1- wasteland/uncultivated land (-58.89), (-61.09), T2- Agriculture-Rice + Mustard (-11.51),(-15.48) T3- Agriculture- Rice + oats (-23.13), (-23.37), T4- Vegetables(beans-chilli) (-13.02), (-12.26) at site A and B respectively showed the values in negative that is loss in the land use system. When the system has tree component in it, it shows gain in the carbon stocks viz. Horticulture (+65.57), (+68.48), Agri-horticulture (+75.97), (+77.16) Agrisilviculture (+95.26), (+85.23) Plantation forest-willow (+142.19), (+132.10) Plantation forest-Poplar (+593.5), (+550.58) and maximum Natural forest-Blue Pine (+915.46), (+853.11) at site A and B respectively (w.r.t Grassland kept as 100). The findings evinced that at both the locations, Natural forest (Blue Pine) land use system were having maximum carbon stocks, carbon sequestration potential, soil carbon pool than all other land use systems and is the best land use system among all the land use systems under investigation. The follower land use system was Plantation forest (Poplar) at both the locations, hence need to be promoted because of having dual advantage of storing carbon and giving additional benefits like timber, fuel wood and fodder. Natural forest-Blue Pine and Plantation forest-Poplar based land use system which are the best two land use systems, they are store houses of carbon in both soil and plants, which need to be conserved for environmental protection. | en_US |
