Availability of Macronutrients and their Relationship with some Soil Properties in Molisols of Udham Singh Nagar District of Uttarakhand, India

Interactive effect of land use systems on depth-wise soil properties and micronutrients minerals in North-Western, India

“…Similar results were opined by Refs. [ 2 , 67 ]. This positive correlation also corresponds to the enhanced soil microbial and enzymatic activitieswhich resulted in greater availability of nutrients in soils [ 30 ].…”

Characterization of the groundwater quality in Udham Singh Nagar of Kumaun Himalaya, Uttarakhand

“…On comparing the different blocks, the excess iron concentration is found in most of Gadarpur, Rudrapur, Bazpur, Khatima & Kashipur blocks and some part of Sitarganj and Jaspur block of the Udham Singh Nagar district. This is because of lowering in pH and slightly reducing conditions, that lead to the reduction of Fe + 3 and their oxides and in turn increased the mobility of Fe(Hodgson, 1963;Prasad et al, 1991;Kumar et al, 2018). The spatial distribution of iron concentration in groundwater of the study area is illustrated in Fig.6.6.…”

“…But the Magnesium ion concentration in groundwater samples surpasses the maximum permissible limit of 30 mg/l in water samples no 7,21,22,23,25,. 26,27, 28,29,30,31,32,35,[40][41][42][43] Excess in Magnesium concentration is found in most of Bazpur block & Gadarpur block, and some part of Kashipur (WSP-35 & 43), Jaspur (WSP-40), Sitarganj (WSP-7) and Khatima (WSP-2) blocks in the Udham Singh Nagar district due to the untreated discharges from the industries. The spatial distribution of concentration in groundwater of the study area is illustrated in Fig.5.5.9.…”

“…Estimation of the Iron (Fe + 2 ) concentrationThe Iron (Fe) ion concentration varies from 0.002 to 4.79 mg/l with an average value of 2.4 mg/l in Rudrapur, Gadarpur, Sitarganj, Khatima, Jaspur, Kashipur and Bazpur blocks of the district. But the Fe ion concentration in groundwater samples crosses the acceptable limit of 0.3 mg/l in sample numbers; WSP-1, 2, 8,9,11,12,14,15, 16,17, 18,22,23,24,25,29,31,33,34,35, 36, 38,39 and WSP-41. The highest value of Fe was found in well number WSP-15 of the Rudrapur block.…”
