  • Improving the Accuracy of Land Cover Classification using Sentinel 2 Data
           

    • Authors: Amal Muhammad Saleh
      Abstract: In this paper, we focus on the use of remote sensing analysis technique with the Sentinel-2 data in order to discriminate land cover in Al-Maimouna District, West of Amara, Iraq. The main objective of the study is to explore whether the expert classification technique can improve the accuracy of land cover classification. In our experiment, an expert classification technique was applied to the Sentinel-2 data set by using, normalized difference vegetation index, soil-adjusted vegetation index, normalized difference water index, modified normalized difference water index, urban index, normalized difference built-up index, normalized difference soil index and bare soil index. Build-up area was found to be the dominant type of land use classified which covers about 41.9% of the total study area, while the least classified was vegetation which accounts for 15.1%. The results of the study demonstrates that the expert classification technique produced an overall accuracy of 88.3%. The results of the study also indicate that by using an expert classification technique, a significantly higher discrimination accuracy can be achieved. Moreover, the expert classification technique reduces problems associated with high-resolution images; while reliabilities are achieved that are better than those achieved with traditional methods.

  • Characterization and Classification of the Mawer Forest Soils of Lesser
           Himalayas of North Kashmir

    • Authors: S.A. Bangroo
      Pages: 10 - 20
      Abstract: Soil is an important component of the forest ecosystem. The inventory and assessment of the forest soil resource provide critical baseline information on forest health and productivity. Therefore, a study for the characterization and classification of the soils of Mawer forest range of North Kashmir Himalayas was conducted. In this study, twelve representative soil profiles along with two altitude gradients on Northern and Southern aspects of Mawer forest range were evaluated for soil characterization and classification. The soils show varying degree of profile development varying from A-B to A-C type with the well-developed sub-surface argillic horizon (Bt) on moderately steep slopes and cambic horizon on steep slopes. The soils are silty loam to loam in texture, slightly acidic to alkaline (pH 5.5 to 6.8) in reaction, non-saline (EC 0.02 to 0.14 dS m-1) with higher organic carbon content on north-facing profiles. Available nutrients are higher on the northern aspect of surface horizons with higher calcium and potassium content on higher altitudes and magnesium and sodium content on lower altitudes. As per soil classification, major soils belong to Udothents and Haploudolls followed by Hapludalfs, Agriudolls, and Eutrochrepts at a great group level.

  • Characteristics of Soils of Lower Indo-Gangetic Plains of West Bengal
           under Rice Cultivation

    • Authors: S.K. Gangopadhyay
      Pages: 21 - 31
      Abstract: Five typical pedons developed from alluvium on lower Indo-Gangetic plain under major land use system of rice from Murshidabad district, West Bengal were studied for their morphological, physical and chemical characteristics. Soils were very deep with varying texture and drainage classes and have some common characters during pedogenesis under impeded drainage condition. Soils were characterized by the redoximorphic features viz., mottle in the form of segregation of Fe-Mn depletion or gleying, mostly in the sub-surface to sub-soil. Soils were strongly acidic (pH 5.1) to slightly alkaline in the surface and neutral (pH 6.5 to 7.5) in the sub-surface to sub-soil, low to high in soil organic carbon (SOC) content (0.40 to 9.60 g kg-1), low to medium in cation exchange capacity (CEC) [4.0 to 42.0 cmol(p+)kg-1] with high base saturation (61 to 90%). Among the exchangeable bases, Ca2+ is the dominant cation followed by Mg2+, Na+ and K+ . Low to medium CEC of soil indicates the mineralogy of the soil as kaolinite and illite (mica). However, clay CEC value indicates the presence of smectite along with hydroxyl-interlayered vermiculite. The high clay CEC value with neutral soil reaction and high content of Ca2+ indicates the dominance of smectite in the soils of pedons 2 and 3. The SOC stock suggested implementation of appropriate conservation measures to the soils of young alluvial plains to improve the quality of soil. The soils of old alluvial plains are generally more fertile in comparison to that of the young alluvial plains. The study indicates that land use has got significant effect on soil characteristics, influencing the soil fertility.

  • Differential Pedogenesis of Some Pseudo-Andic and Non-Andic Soils in a
           Toposequence of Andaman and Nicobar Islands

    • Authors: Siladitya Bandyopadhyay
      Pages: 32 - 43
      Abstract: A large scale soil survey with high resolution image data and classification has been conducted to understand soil genesis of North and Middle Andaman district soils with emphasis of some pseudo-Andic and non-Andic nature in a topographical sequence for the first time. The study of soils showed sandy loam to silty clay loam texture, low in bulk density (0.96-1.22 Mg m-3) very strongly acidic (pH 4.6) to strongly alkaline (pH 9.0) with medium to high (7.4-9.8 g kg-1) organic carbon. Bulk density has a significant negative correlation with Feo (r = -0.74**), Feo/Fed (r = -0.77**) and Alo+0.5Feo (r = -0.73**), indicating the direct influence of amorphous Fe and Al on lowering bulk density of soils. Cation exchange capacity (CEC)/clay has also significant negative correlation with Feo (r = -0.53**), Feo/Fed (r = -0.60) and Alo+0.5Feo (r = -0.52**). Bulk density, acid oxalate extractable Fe (Feo) and Al (Alo), citrate-bicabonate-dithionate extractable Fe (Fed), percentage of Alo plus half the Feo and Feo/Fed ratio were proven to be the appropriate indicators of Pseudo-Andic properties in soils. Pseudo-Andic soils were classified as Aquandic Fluvaquents in interspersed valleys, Aquandic Endoaquepts in coastal plains and Aquandic Endoaqualfs in volcanic mudflats. Non-Andic soils were formed in uplands (Typic Hapluudalfs) and alluvial plains (Typic Endoaqualfs). The study inferred that effect of volcanic ejections was very much prominent in coastal plains, mangroves and swamps and has been spread up to the interspersed valleys. Soils on uplands and alluvial plains did not experience little or no influence of volcanic eruptions and found matured profiles. Soils on coastal region were environmentally most vulnerable and needs appropriate conservation measures. Vulnerability of coastal plain soils and typical pseudo-Andic soils observed require a special soil and land management to protect and maintain soil health and productivity. Criteria used to characterize the nature and vulnerability risk helps to manage similar kind of soils elsewhere for land use plan.

  • Agro-Ecological Sustainability of Farming Systems in Punjab and Haryana

    • Authors: Chhabilendra Roul
      Pages: 44 - 54
      Abstract: This paper focuses on the quantitative assessment of the ecological sustainability of agricultural production in Punjab and Haryana, the breadbasket of India. To compute the sustainability, we used indicators on (i) state of soil and its management (ii) weather, climate, and water management, and (iii) biodiversity, environment and climate change. Using data from secondary sources, a composite index of ecological sustainability and indices for three individual dimensions were computed. The indices show a moderate level of ecological sustainability in Haryana and Punjab. Biodiversity and environment were the most eroded dimensions of sustainability needing special attention. Though important for improving soil health, the traditional leguminous-crop-based cropping patterns are disappearing from these states. The residues of crops are rich repository of carbon and bacteria, and the nitrogen supplied by legume crops facilitates their decomposition and their conversion to soil-building organic matter. Both the states need to focus on policy changes regarding pricing water and power and incentivizing the adoption of microirrigation and other modern irrigation practices to improve agricultural sustainability in these aspects.

  • Land Use Systems and Soil Properties in Mokokchung District of Nagaland,
           India

    • Authors: Y.K. Sharma
      Pages: 55 - 60
      Abstract: Present investigation was conducted during 2017-18 to study the impact of different land use systems on soil properties. A total of seventy two surface soil samples were collected from twelve villages of six hill ranges of Mokokchung district of Nagaland, India. The soil samples were collected from the fields of jhum, settled and forest land use systems and were analyzed for different properties. Results revealed that the soils were strongly to moderately acidic in reaction and low in cation exchange capacity (CEC) and forest soils showed higher CEC than that of soils of jhum and settled land uses. Almost similar values of bulk density and porosity were reported in the soils of all land uses. On the basis of nutrient index, soils of all three land uses were high in organic carbon (OC), medium in available nitrogen (N), potassium (K) and sulphur (S), except jhum soils for phosphorus (P) and settled soils for sulphur (S), which were high and low in P and S status, respectively. Forest soils contained high amount of OC, available N, P, K, S and exchangeable calcium (Ca) and magnesium (Mg) than other soils. Available N, P, K, S, Ca and Mg were significantly and positively correlated with OC. Available P, Ca and Mg of the soils of all three land uses and N and S of settled soils had significant and positive correlations with soil pH. Total potential acidity of the soils was quite high and accounted for severe acidity problem in these soils. Reasonable quantity of various forms of acidity was reported in the soils. Quantum of various forms of acidities was high in forest soils except extract acidity, which was recorded high in jhum soils. Significant and negative correlation was observed among acidity components and soil pH. Extractable acidity in settled soils and exchangeable aluminium (Al3+) in settled and forest soils showed significant negative correlation with OC.

  • Spatial Mapping of Soil Moisture in an Agricultural Farm through
           Geostatistical Approach

    • Authors: Debashis Chakraborty
      Pages: 61 - 68
      Abstract: Spatiotemporal changes in near-surface soil moisture (NSSM; 0-5 cm) were captured over the research farm (242 ha) at ICAR-Indian Agricultural Research Institute, New Delhi during rabi (winter) season by applying geostatistical techniques. Ranges of NSSM have been different on different days, and was not related to either bulk density or clay content of the surface layer. Even the best-fitting semi-variogram models were different with an average root mean square error of 6.8 over the study period. The minimum separation distance between two sampling points was ~6 m, and nearly 50% variability could be explained by the nugget indicating small scale variations of soil moisture. Spatial variability maps of NSSM were prepared using ordinary kriging wherein a few distinct wetness zones were apparent. Sub-surface soil moisture (SSSM) was correlated with NSSM till 40 cm depth, making plausibility of root-zone soil moisture mapping from surface measurements. The kriged maps will help in scheduling irrigation and deciding sowing dates over a large farm with limited number of in-situ point observations.

  • Assessment of Soil Quality and Spatial Variability of Soil Properties
           Using Geo-Spatial Techniques in Sub-Humid Southern Plain of Rajasthan,
           India

    • Authors: Sunil Kumar
      Pages: 69 - 85
      Abstract: Soil quality and spatial variability of soil properties and their impact on the growth and yield of crops are important concerns for sustainable and site-specific nutrient management. The present study was conducted in soils of sub-humid southern plains of Rajasthan to understand the soil quality and spatial variability of soil properties using geospatial techniques. Among the different tehsils, Rashmi tehsil had the highest (0.674) soil quality index (SQI) whereas, the highest deterioration was observed in soil quality of Begun (0.557) tehsil of Chittorgarh district of southern Rajasthan. Soil pH ranged from 5.70 to 8.50 and moderately saline to highly saline soils were found in 2-5% area. Soil organic carbon (SOC), KMnO4-N, Olsen-P, NH4OAc-K, available Zn, Fe, Cu, Mn, soil pH and electrical conductivity (EC) were determined. Coefficient of variation (CV) indicated that EC, DTPA extractable Fe, Cu and Mn were high in heterogeneity (CV > 35%) whereas, SOC, Olsen-P and NH4OAc-K showed moderate heterogeneity (CV 15-35%). The spatial variability maps of soil properties indicated that SOC was deficient in 47.0% area whereas, KMnO4-N, Olsen-P and NH4OAc-K were low in 14.8, 7.56 and 26.5% area, respectively. DTPA extractable Zn and Mn were found low in 16-20% area while, DTPA-Fe was low in 47.7% area. Principal component analysis (PCA) representing 56.4% of the total variance, first PC explained 19.3% of the total variation while, PCs second, third and fourth explained 13.8, 12.6 and 10.4, respectively. The SOC was significant and positive correlation with available K, DTPA-Fe and Cu while it had significant negative correlation with soil reaction (soil pH).

  • Modelling and Prediction of Soil Organic Carbon using Digital Soil Mapping
           in the Thar Desert Region of India

    • Authors: P.C. Moharana
      Pages: 86 - 96
      Abstract: In the present study, the distribution of soil organic carbon (SOC) was investigated using digital soil mapping for an area of ~29 lakhs ha in Bikaner district, Rajasthan, India. To achieve this goal, 187 soil profiles were used for SOC estimation by Quantile regression forest (QRF) model technique. Landsat data, terrain attributes and bioclimatic variables were used as environmental variables. 10-fold cross-validation was used to evaluate model. Equal-area quadratic splines were fitted to soil profile datasets to estimate SOC at six standard soil depths (0-5, 5-15, 15-30, 30-60, 60-100 and 100-200 cm). Results showed that the mean SOC concentration was very low with values varied from 1.18 to 1.53 g kg-1 in different depths. While predicting SOC at different depths, the model was able to capture low variability (R2 = 1–7%). Overall, the Lin’s concordance correlation coefficient (CCC) values ranged from 0.01 to 0.18, indicating poor agreement between the predicted and observed values. Root mean square error (RMSE) and mean error (ME) were 0.97 and 0.16, respectively. The values of prediction interval coverage probability (PICP) recorded 87.2–89.7% for SOC contents at different depths. The most important variables for predicting SOC concentration variations were the annual range of temperature, latitude, Landsat 8 bands 2, 5 and 6. Temperature-related variables and remote sensed data products are important for predicting SOC concentrations in arid regions. We anticipate that this digital information of SOC will be useful for frequent monitoring and assessment of carbon cycle in arid regions.

  • Impact of Long-term Manures and Balanced Fertilization on Soil Carbon
           Pools in Mollisols under Rice-Wheat Cropping System

    • Authors: Mohd. Yaseen
      Pages: 97 - 105
      Abstract: This paper assesses the impact of long-term (30 years) application of balanced fertilizers with or without farmyard manure (FYM) on soil carbon pools after harvest of rice under intensively cultivated rice-wheat cropping system. Soil organic carbon (SOC) and its fractions were evaluated in soil (Aquic Hapludoll with silty loam) during 2014-15 from an ongoing long-term field experiment (LTFE) initiated in 1984 at Crop Research Centre of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar. Fourteen fertilization treatments with different levels of nitrogen (N), phosphorus (P), potassium (K), with or without FYM and zinc (Zn) were arranged in a randomized block design. Findings of investigation revealed that application of 100% NPK (N120+P40+K40) and super optimal NPK (N180+P80+K40) along with FYM and Zn increased SOC by 51.5 and 58.7 per cent, particulate organic C by 41.4 and 45.4 per cent, water soluble C by 77.9 and 86.4 per cent, hot water extractable C by 91.2 and 97.1 per cent, water soluble carbohydrates by 187.3 and 204.9 per cent, potentially mineralizable C by 107.6 and 114.5 per cent, KMnO4 oxidizable C by 43.1 and 47.0 per cent and microbial biomass C by 66.3 and 64.4% over control in entire 0-60 cm soil profile, respectively. It was also found that rice grain yield was increased by 222.2 per cent over control with the application of 100% NPK (N120+P40+K40) along with FYM and Zn. Therefore, from this experiment it is concluded that application of balanced optimal and super optimal NPK along with FYM and Zn (N120+P40+K40+Zn+FYM and N180+P80+K40+Zn+FYM) in intensively cultivated cropping system is a sustainable management practice to sustain soil fertility by accumulating and sequestering sizable carbon in soil and enhanced production of rice-wheat cropping system.

  • Physicochemical Properties and Nutrient Contents of Compost as Influenced
           by Organic Wastes and Methods of Composting

    • Authors: Bidhan Chandro Sarker
      Pages: 106 - 112
      Abstract: Compost is the decomposed organic materials that can be used to the degraded soils which is one of the best options to improve the soil organic matter and soil productivity. Suitable organic wastes and appropriate method of composting are important aspects for recycling product that help to chemically transform organic wastes into a valuable soil amendment. Therefore, the present study was conducted to evaluate the composition of physicochemical properties and nutrient contents of compost prepared from different organic wastes following different methods of composting. The factorial experiment consisted of three organic wastes (S1= Kitchen waste, S2= Municipal waste and S3= Browns) and two composting methods (M1= Surface heap method and M2= Trench method) with four replications. The analysis of variance showed that physicochemical properties and nutrient contents of compost were substantially influenced by the use of different organic wastes and methods of composting. Kitchen wastes with trench method of composting resulted in higher particle density (1.79 Mg m-3), porosity (70.1%), saturation (20.1%), total N content (1.59%), total K content (0.84%), total organic carbon (17.6%) and C:N ratio (11.69), whereas porosity (70.1%) and Zn content (3.31 mg kg-1) were higher in kitchen wastes with the surface method of composting. The findings of this experiment revealed that the physiochemical properties and nutrient contents of compost was better when prepared from kitchen wastes by trench method of composting.

  • Effect of Potassium and Zinc Application on Crop Yield and Uptake of
           Nutrients in Green gram (Vigna radiata L.) under Coarse Textured Soils

    • Authors: M.K. Jat
      Pages: 113 - 118
      Abstract: The aim of present study was to find out the optimum dose and application effect of potassium (K) and zinc (Zn) on green gram yield, nodulation, uptake and its build-up/depletion in soil to overcome the production of pulses in Haryana. A series of field experiments were conducted during kharif season from 2018 to 2020 at the Regional Research Station, Chaudhary Charan Singh Haryana Agricultural University (CCSHAU), Bawal, Haryana. The experiment was laid out in a split plot design with four levels of K (0, 10, 20 and 30 kg K2O ha-1) in main plot and Zn (0, 12.5, 25 and 37.5 kg ZnSO4 ha-1) in sub-plot with three replications. The results revealed that application of K significantly affected the yield of green gram up to 20 kg K2O ha-1 whereas Zn application significantly affected the yield of green gram up to 25 kg ZnSO4 ha-1. The interaction between K and Zn was non-significant. The nodules fresh weight and number of nodules per plant increased significantly with the application K whereas, these parameters increased with the application of Zn but results were not significant. The K and Zn application significantly increased their content and uptake in seed and straw of green gram. The available K in soil was influenced by K application but was found to be significant with 20 and 30 kg K2O ha-1. The DTPA extractable Zn content in soil after harvest of crop was also significantly higher with the application of zinc sulphate.
