ABSTRACT

A study was undertaken in Central Haryana comprising Jhajjar, Karnal, Panipat, Sonipat and Rohtak districts to estimate SOC stock under different forests covers available there as well as in other different land uses viz. block plantations, horticulture, agroforestry and agriculture. In central region of Haryana, Maximum SOC stock was under forests (37.17 t ha- 1) followed by plantation (27.04 t ha-1), horticulture (26.28 t ha-1), agroforestry (26.08 t ha-1) and the least SOC stock was under agriculture land use (20.39 t ha-1). Subset for ? = 0.05 indicate that forest stands separately (a), plantation, horticulture and agroforestry were statistically at par therefore, grouped together (b) while agriculture stand separately (c). SOC stock under forests was 37.46 %, 41.44 %, 42.52 % and 82.30 % higher as compared to plantation, horticulture, agroforestry and agriculture land use respectively. Total organic carbon stocks in the soils under forests in five districts comprising the central region of Haryana had 1.07 million tons. Out of these, Karnal district has the maximum SOC stock (409720.40 t) followed by Sonipat (258668.85 t), Panipat (156488.42 t), Rohtak (139336.02 t) and the least SOC stock was in Jhajjar district (10.5910.59). Total SOC stocks under horticulture in five districts comprising the Central region of Haryana had 191303.85 tons. Out of these, Karnal district has the maximum SOC stock (63833.64 t) followed by Sonipat (41243.02 t), Jhajjar (38109.40 t), Panipat (24653.47 t), and the least SOC stock was in Rohtak district (23464.32 t). Organic carbon stock in the soils under Bhindawas Wildlife Sanctuary was 12481.86 tons and in Khaparwas Wildlif Sanctuary was 2313.96 ton. Total organic carbon stock in the soils in wildlife sanctuaries situated in central region of Haryana, was 14795.82 tons.
