Abstract :
This study was conducted for the comparison purpose with the objective to investigate the effect of similar vegetation growing in different soil conditions and environment on the soil carbon sequestration in the form of soil organic carbon stock. Under forest land use, SOC stock under chir forests growing in
Uttarakhand was 61.10 t ha-1, under miscellaneous forests was 58.23 t ha-1 and under sal forest was 58.45 t ha-1 while in Haryana it was 58.94 t ha-1 under chir, 43.55 t ha-1 under miscellaneous and 40.96 t ha-1 under sal forests. SOC stock under miscellaneous and sal forests growing in Uttarakhand was statistically significant difference with the SOC stock in similar forests growing in Haryana. Eucalyptus plantation growing in Uttarakhand was having 31.94%, khair plantation 17.98 % and shisham 41.83 % higher SOC stock as compared to similar plantations growing in Haryana. Only poplar plantation was 5.32% higher SOC stock in Haryana as compared to poplar plantations growing in Uttarakhand. SOC stock under shisham and eucalyptus plantations growing in Uttarakhand have statistically significant differences with the SOC stock
under similar plantations growing in Haryana. Under horticulture land use, SOC stock under mango growing in Uttarakhand was 50.70 t ha-1 while growing in Haryana was having 36.25 t ha-1. Organic carbon stock in soils under citrus and guava orchards in Uttarakhand was 47.55 t ha-1 and 40.21 t ha-1 and growing in Haryana was 27.41 t ha-1 and 29.45 t ha-1 respectively. SOC stock under mango, citus and guava orchards growing in Uttarakhand was statistically significant differences with SOC stock in Haryana in similar vegetation. Under agroforestry land use, sugarcane–poplar model growing in Uttarakhand was 33.48 t ha-1 SOC stock while similar model growing in Haryana was 25.14 t ha-1. SOC stock under wheat–poplar model in Uttarakhand was 24.81 t ha-1 while in Haryana was 31.07 t ha-1 SOC stock which was statistically significant different.
