SOIL QUALITY STATUS OF TUNGA LEFT BANK COMMAND AREA, SHIMOGA & DAVANAGERE DISTRICTS, KARNATAKA, INDIA
The success of soil management to maintain soil quality depends on an understanding of how soils respond to agricultural use and practices over a time. As a result, the important physico-chemical parameters of soils were studies under different land use systems. The Tunga Left Bank Canal Command (TLBC) area lies in between 750 31’ to 750 40 E and 130 50’ to 140 02’ N forming a part of Shimoga and Davangere districts of Karnataka state. About thirty soil samples were collected in the study area during the pre-monsoon season (April-May 2007) and were analyzed for the physico-chemical parameters viz; pH, EC,N,P2O5, K2O and micronutrients such as Fe, Mn, Zn and Cu. From the above study area it is noted that the physico-chemical parameters are in these range i.e., pH varies from 6.7 to 7.7, EC varies from 0.14 to 0.32 dSm-1142 to 246 Kg/ha, available P2O5 varies from 14 to 27 Kg/ha, available K2O varies from 135 to 173 Kg/ha. In the case micronutrients, Fe varies from 12 to 18 ppm, Mn varies from 5.0 to 8.1 ppm, Zn varies from 0.63 to 1.83 ppm and Cu varies from 0.36 to 1.1 ppm. The results obtained indicate that all the soil samples of the present study are within the permissible limits for agricultural purposes.
Surface Water Quality Status of Tunga Left Bank Command, Shimoga & Davangere Dist, Karnataka, India
Tanks are the major source of irrigation but in recent times due to substantial failure in rainfall the surface water bodies are getting dried up. The ever increase in demand for water resource warrants refinement in the agricultural practices. The Tunga Left Bank Command (TLBC) forms a part of Shimoga and Davanagere districts. Some of the tanks in TLBC are canalfed and others tanks are of irrigation returns. Consequently, it is important to know the suitability of the water for irrigation. In the present study, about fifteen water samples were collected from the tanks of TLBC and analyzed for physico-chemical parameters viz; pH,EC,TH,TDS ,Ca,Mg,Na,K,CO3,HCO3,PO4,Cl and SO4. The irrigation water quality characteristics, such as Exchangeable Sodium Percentage (ESP) values of canal-fed and unconnected tanks ranges from 0.054 to 2.216 and the values of Sodium Adsorption Ration (SAR) vary from 0.111 to 5.05. Similarly the values of Mg hazard vary from 15.9 to 76.6. The resulted obtained indicate that all the water samples of present study are within the permissible limits for irrigation purposes.
Analysis of Water quality using Physico-Chemical Parameters Hosahalli tank in Shimoga
This Paper deals with the Physico - chemical Parameters of Hosahalli Water Tank in Shimoga District, Karnataka. Monthly Changes in Physical and Chemical Parameters Such as Water Temperature, Turbidity, Total Dissolved Solids, pH, Dissolved Oxygen, Free Carbon dio for a periods of one year from 1st January 2007 to 31st December 2007. All Parameters were within the permissible limits. The results indicate that the tank is Non-polluted and can be used for Domestic, Irrigation and Fisheries.
Mobile network System of Bhadravathi Town using Remote Sending, GIS & GPS, Shimoga District, Karnataka, India.
The use of wireless systems is a very attractive option in the design and development of communication networks, especially with the expansion of cellular telephony and wireless computer networks as their industries seek to increase the number of services and speedy transmission available to their customers. For this transmission needs towers and the location of […]
Surface Water Quality Status in the part of Bhadravathi Industrial Town, Shimoga District, Karnataka, India.
In order to know the surface water pollution in the part of Bhadravathi industrial town, Shimoga District, Karnataka state, the present study has been conducted around Mysore Paper Mill (MPM) solid waste dump site, which may be the source of pollution. Nine surface water samples were collected and analyzed for physico-chemical parameters and heavy metal concentrations. The results indicated that the concentration of Na is high in two samples and very high in three samples. The increase in the concentrations of Na and K in surface water samples may be probably due to the agricultural run-off and effluents discharged from the industries.
