Abstract:

A field study on Characterization of soils of Lower Dibang Valley District of Arunachal Pradesh, North East India was carried out at Krishi Vigyan Kendra, Lower Dibang Valley district of Arunachal Pradesh North East India during 2017-18. The soil properties of different villages revealed that the soil reaction (pH) ranges from 4.3 to 5.3. The lowest soil pH was recorded in Rayang village and the higher pH value of 5.3 recorded in Kangkog, Balek and Rukmo villages. Organic Carbon values ranged from 0.80-2.00 and are categorized as medium to high in range. The soluble salt content of soil measured in terms of electrical conductivity of soil solution (dS/m) which recorded as normal in range in all the soils of the villages (0.02 to 0.3 dS/m). The soils of different villages, 23.0 percent of soil samples belongs to low category with respect to available nitrogen status and 40 percent of soil samples fall in the category medium and high. The available nitrogen content ranges from 118.7 to 366.5 kg/ha). The available P content of soil ranges from 20.7 to 94.73 kg/ha. However higher P content was recorded in Jia village and lowest P content recorded in Rumo village. Higher P content in soil was due to higher organic carbon content of soil where P fixation in soil reduced and which resulted in more availability of P in soil. In general 61.3 percent soils are high in K status and 38.46 percent soils belongs to medium in range of K in soils. However, none of the soils fall under category of low K status in soil. The maximum Sulphur content was recorded in Horupahar village which recorded highest of 65 kg/ha (high in rage).Sulphur content ranges from 14.0 to 65.0 kg/ha. As regard to micronutrient status of soil, the available zinc content of soil ranges from 0.18 to 2.74 ppm. In general 23.0 percent of soils belongs to high Zinc content of soil and 10.0percent of soils categorized as low in Zinc status and 20 percent of soils belongs to medium in Zinc status. The available boron content of soil ranges from 0.18 to 6.53 ppm among the soils of different villages. However the 69 percent of soils fall in the category of higher boron content, 23 percent soils belongs to medium in boron content and 15 percent soils having low boron content in soils. The Manganese content in soil ranges from 0.45 to 19.5 ppm across the villages of lower Debang Valley. However higher manganese content of soil recorded in Kebali, Balek, Jia, Iduli, Horupahar, Bolung, Koronu and Meka and cover 53.84 percent of soils of different villages. Iron content of soil ranges from 21.0 to 106 ppm and all the soils belongs to higher range of iron status in soil. The available copper content of soil ranges from 0.37 to 4.09 ppm among the soils at different locations.
