Using automated soil water content measurements to estimate soil water budgets

Canadian Journal of Soil Science, 2006
The distribution of precipitation into the components of a soil water budget has a profound impact on crop growth, groundwater recharge, soil erosion, and groundwater and surface water contamination levels. The main objectives of this study were to develop a new method of measuring soil water balances and to demonstrate the use of the method in ...

Soil Water Repellency: Effects of Water Content, Temperature, and Particle Size

Soil Science Society of America Journal, 1999
Abstract Water repellency (WR) of soils is a common problem in many countries. It can cause a reduction in the rate of water infiltration into soils as well as an unstable water flow within the soil matrix. Water repellency has typically been related to dry soils.

WATER CONTENT AND SOIL STRENGTH

Journal of Soil Science, 1960
Summary The strength of beds of soil aggregates, saturated and unsaturated, has been measured with a ring shear machine. For saturated loose soil with free drainage the cohesion and friction components and, therefore, total strength are proportional to the applied normal load. When sheared under load the soil compresses to an ultimate

Spectrophotometric Determination of Soil Water Content

Soil Science Society of America Journal, 1972
Abstract The absorbance at 1.94µ by a soil‐methanol extract was used for measuring the soil water contents of three different textured soils. A linear relation between absorbance and soil water content was adequate for moisture determinations ranging from air dry to the moisture equivalent. For Quincy loamy sand and Barnes loam soils,

Soil Water Content: Microwave Oven Method

Soil Science Society of America Journal, 1974
Abstract The moisture content of two soils was determined rapidly with a microwave technique. Equations were developed for estimating soil drying times for two soils of different texture at different moisture contents and for different sample sizes.

Estimating Soil Water Content Using Cokriging

Soil Science Society of America Journal, 1987
Abstract Using cokriging estimates, and estimation variances of the gravimetric moisture content (GMC) were made using one and two additional random functions: the bare soil surface temperature and the percent sand content. The semivariograms and cross‐semivariograms were obtained as well as the sample correlation between the GMC and ...

Soil Organic Matter Content and Volumetric Water Content Affect Indaziflam–Soil Bioavailability

Weed Science, 2016
Indaziflam is a cellulose biosynthesis-inhibiting herbicide for annual weed control in various agricultural systems. Sporadic cases of unacceptable injury to desirable plants have been reported after indaziflam application, which may have been due to conditions favoring increased indaziflam–soil bioavailability. Research was conducted from 2013 to 2015

Soil-Water Content and Its Measurement

2018
Soil-water content is the basic state characteristic of soil; it expresses the relative quantity of water in the soil. Soil-water content can be expressed as the ratio of water amount and the amount of soil. The most frequently used term is volumetric soil-water content, which is the ratio of water volume and soil volume containing water.

Solute Transport Through Soil With Nonuniform Water Content

Soil Science Society of America Journal, 1978
Abstract An approximate analytical solution is presented for steady flow of salt through soil with a nonuniform distribution of the water content. The solution is in good agreement with a numerical computer solution, provided by the CSMP simulation language.
