Abstract In the modern era, intensive agricultural practices such as agrochemicals are applied in excessive amounts to enhance production. However, imbalanced adoption of these chemicals has arisen dwindling agriculture factor productivity and soil quality. To maintain fertility production, chemical fertilizers must be supplemented with organic inputs. Keeping this backdrop, a research trail was established during 2018–19 2019–20 years at Research Farm Agriculture University, Kota, India....
Soil depth is essential for eco-hydrological modeling, carbon storage estimation, and land evaluation, yet its spatial variation often poorly understood rarely mapped, particularly in complex landscapes with limited sample sizes. Digital soil mapping, employing various machine learning methods, has become crucial predicting mapping attributes. This study investigates distribution Rajasthan Gujarat, India, using techniques. A total of 37 environmental variables were examined to identify...
Wind erosion is a major natural disaster worldwide, and it key problem in western Rajasthan India. The Analytical Hierarchy Process (AHP), the Geographic Information System (GIS), remote sensing satellite images are effective tools for modeling risk assessment of land degradation. present study aimed to assess model degradation vulnerable (LDV) zones based on AHP geospatial techniques Luni River basin Rajasthan, This was carried out by examining important thematic layers, such as vegetation...
Changes in land use have several impacts on soil organic carbon (C) and nitrogen (N) cycling, both of which are important for stability fertility. Initially, the study area was barren uncultivated desert land. During late 1960s, introduction a canal arid region converted deserts into cultivated The objectives present were to evaluate effects various systems temporal changes C N pools, usefulness different management indices suitable sustainable under conditions. We quantified pools five uses...
Phycoremediation is a cost effective, environmentally sustainable, safe and alternative technology for remediation of wastewater. The present work was aimed to evaluate the role inoculated microalgae (Chlorella minutissima) in phycoremediation sewage selected removed 94.4% TDS, 88.9% NO3 -N, 66.3% potassium, 67.4% phosphorus, 48.2% NH4 +, 93% (Biological Oxygen Demand) BOD5 80.5% (Chemical COD. wastewater obtained after have limit nutrients be used as irrigation water agricultural fields....
Soil quality and spatial variability of soil properties their impact on the growth yield crops are important concerns for sustainable site-specific nutrient management. The present study was conducted in soils sub-humid southern plains Rajasthan to understand using geospatial techniques. Among different tehsils, Rashmi tehsil had highest (0.674) index (SQI) whereas, deterioration observed Begun (0.557) Chittorgarh district Rajasthan. pH ranged from 5.70 8.50 moderately saline highly were...
Micronutrient deficiency in cultivable soil, particularly that of iron (Fe) and zinc (Zn), is a major productivity constraint the world. Low Fe availability due to low solubility oxidized ferric forms challenge. An experiment was, thus, executed assess performance eight genetically diverse rice genotypes on Fe-sufficient (100 µM) Fe-deficient (1 nutrient solution, their ability recover from was measured. efficiency under terms biomass production showed significant positive correlation with...
Understanding the dynamics of vegetative greenness and how it interacts with various hydroclimatic factors is crucial for comprehending implications global climate change. The present study utilized MODIS-derived normalized difference vegetation index (NDVI) to understand patterns over 21 years (2001–2021) in Rajasthan, India. rainfall, land surface temperature (LST), evapotranspiration (ET) were also analyzed. changes, at a 30 m pixel resolution, evaluated using Mann–Kendall’s trend test....
The evaluation of soil quality is essential in monitoring the long term effects rice cultivation. Present study investigated cultivation on properties and organic C pools identified indicators for Ghaggar-flood plains hot arid India. Soil samples were collected from fields with 0, 10, 20, 30 40 years revealed that electrical conductivity (EC) exchangeable sodium percentage (ESP) increased after 30–40 Available nutrients increasing carbon namely, total (TOC), Walkley Black (WBC) particulate...
Iron deficiency is a serious nutritional disorder in aerobic rice, causing chlorosis, poor yields and reduced grain quality. The problem can be managed by complementing the use of Fe-efficient plant type with suitable Fe management strategy. In present paper, we report effect eight iron practices to resolve (Fe) chlorosis through an tolerant (IDTR) susceptible (IDSR) rice genotype, i.e. Pusa 33 ADT 39, respectively. tolerance these genotypes was related root release PS which enabled higher...
ABSTRACTSoil inorganic carbon (SIC) is important reservoirs in desert ecosystems. However, little attention was paid to estimate stock these regions. In the present study, distribution of SIC investigated using digital soil mapping Bikaner district, Rajasthan, India. A total 187 profiles were used for estimation by Quantile regression forest model. Landsat data, terrain attributes and bioclimatic variables as environmental variables. Ten-fold cross-validation evaluate Equal-area quadratic...
Land surface temperature (LST) and its interaction with normalized difference vegetation index (NDVI) is crucial for better understanding of environmental changes in current scenario. However, very few or scanty research on the interrelationship between LST, NDVI topographic elements has been done India. Therefore, purpose conducting this study was to examine, how LST change as a function elevation Rajasthan. In present study, MODIS derived digital model (DEM) from shuttle radar topography...
In the present study, distribution of salinity was investigated using digital soil mapping (DSM) algorithmsin 5 km buffer zone both side Indira Gandhi Nahar Pariyojana (IGNP) canal system Suratgarh tehshil in Rajasthan. To achieve this goal, 64 samples were used with 21 environmental covariates and 3 DSM algorithms. Result from study showed that difference between minimum maximum ECe is very high (35.55 dS m-1) different irrigation IGNP system. The ranged 0.50 to 36.05 dSm-1. Results...
