Abstract. In this paper, we present and analyze a novel global database of soil infiltration measurements, the Soil Water Infiltration Global (SWIG) database. total, 5023 curves were collected across all continents in SWIG These data either provided quality checked by scientists who performed experiments or they digitized from published articles. Data 54 different countries included with major contributions Iran, China, USA. addition to its extensive geographical coverage, cover research...
Salinity as an important property of soil plays a major role in reducing the fertility world. Accurate information about spatial change salinity is essential for sustainable management and utilization agriculture lands. For this purpose, 150 samples were collected from Dashte-e-Tabriz Iran tested was estimated by land surface parameters including elevation, aspect, length slope, wetness index, slope normalized difference vegetation index basic parameters. In order to model predict salinity,...
Abstract The paper presents a study on the effect of soil matric suction variation leaf chlorophyll index and nitrogen concentration canola. Results showed that increases exponentially with suction, especially at late season canola growing time. At moderate (200 300 kPa heads), remains nearly constant, but in drier (matric >300 kPa), gradually Despite total it is similar to index, results - curve has demarcated bi-modal shape. We suggest 2.7% 69.8 value represent upper limit meter...
Optical trapezoid model (OPTRAM) as a method has been proposed to retrieve soil moisture from remote sensing data. It is based on the assumption that trapezoidal shape would be derived plotting of vegetation index (VI) versus shortwave-infrared transformed reflectance (STR) data assuming linear relationship between VI and STR. A literature review present study indicate STR under both dry wet conditions, especially in wide range cover, nonlinear. Therefore, we modified OPTRAM by introducing...
In coarse-textured soils, low water and nutrient holding capacity due to the high number of macropores limits crop growth. To minimize these limitations application various soil conditioners (SCs) has been extensively used in recent decades. The objective this study was investigate influences anionic polyacrylamide (PAM), cattle manure (M), vermicompost (VC), biological sludge (BS) as organic SCs on mean weight diameter (MWD) aggregates, aggregate stability (WAS), pore size distribution...
Choosing a particular textural fraction as an erodibility predictor is often confusing because various fractions of soil particles have been introduced index by many researchers. Recently, advances in fractal theory scaling parameter for characterizing fragments. The objectives this study were (i) to test the applicability dimension particle size distribution (PSD) estimation interrill and (ii) relationship between texture components. Samples from 36 series with contrasting characters...
The integral water capacity (IWC) approach takes into account various soil physical limitations for calculating plant available water. However, the IWC cannot distinguish differences in uptake between plants. Therefore, objectives of this study were i) to modify include physiological properties redefine wet and dry ends IWC, called IWCplant ii) evaluate performance using experimental data. restrictions imposed by poor aeration rapid drainage flux calculated both end IWC. hydraulic resistance...
Unsaturated soil hydraulic conductivity K is a fundamental transfer property of but its measurement costly, difficult, and time-consuming due to large variations with water content (θ) or matric potential (h). Recently, C. Doussan S. Ruy proposed method/model using measurements the electrical core samples predict K(h). This method requires setting range potentials h in samples—a possible lengthy process requiring specialised devices. To avoid estimation, we propose simplify that by...
Abstract In his seminal paper on the solution of infiltration equation, Philip (1969), https://doi.org/10.1016/b978-1-4831-9936-8.50010-6 proposed a gravity time, t grav , to estimate practical convergence time and domain validity infinite series expansion, TSE, for describing transient state. The parameter refers point in where is dominated equally by capillarity as derived from first two (dominant) terms TSE. Evidence suggests that applicability truncated two‐term equation has limit...
Abstract. In this paper, we present and analyze a global database of soil infiltration measurements, the Soil Water Infiltration Global (SWIG) database, for first time. total, 5023 curves were collected across all continents in SWIG database. These data either provided quality checked by scientists who performed experiments or they digitized from published articles. Data 54 different countries included with major contributions Iran, China, USA. addition to its spatial coverage, cover time...
Soil moisture and compaction are important factors for growth development of plant root. This study was conducted as a nested design with two three replications to investigate the behaviour pistachio seedling roots at different levels soil in sandy loam under greenhouse conditions. The first factor four bulk density (1.35, 1.5, 1.65, 1.8 g/cm3). second six ranging 0.07-0.49 cm3/cm3. Moisture monitoring each treatment carried out by time domain reflectometer device every days. At end...
Rainfall erosivity of the Revised Universal Soil Loss Equation (RUSLE) is influenced by type, amount, and intensity storm. In this research, rainfall data from 18 recording rain gauge stations were collected analyzed. Further, their single storm, daily, monthly, annual erosion indices calculated estimated different models. Duration each was divided into 15 min intervals. Intensity energy interval, maximum 30 min, total rainfall, index every storm calculated. Furthermore, Cooley's model for...
