Research on the effect of straw mulching on the soil moisture by field experiment in the piedmont plain of the Taihang Mountains
Straw mulching Soil moisture Soil water content Deep layer Soil moisture conservation
2018/3/23
To reveal the influencing effect of the long-term straw mulching on the soil moisture, this paper employed the field experiment data in 2010 of a typical area of Taihang Mountains plain, observed the ...
The top 2 inches of topsoil on all of Earth’s landmasses contains an infinitesimal fraction of the planet’s water — less than one-thousandth of a percent. Yet because of its position at the interface ...
Soil moisture,snowpack data could help predict 'flash droughts'
Soil moisture snowpack data flash droughts
2016/11/4
New research suggests that "flash droughts" — like the one that unexpectedly gripped the Southern Rockies and Midwest in the summer of 2012 — could be predicted months in advance using soil moisture a...
Field and laboratory ad hoc calibrations of Virrib and ThetaProbe dielectric sensors for soil moisture measurements
Virrib ThetaProbe one-point loam loamy sand zone of influence bulk density offset FertOrgaNic
2015/2/4
For the research of irrigation optimization and nitrate leaching it is important to know the short-term soil moisture variation during percolation episodes as well as its seasonal pattern. Dielectric ...
TRANSMISSION LINE THEORY BASED TWO LAYER MODEL FOR DETERMINING SOIL MOISTURE
Soil Moisture Impedance Genetic Algorithm Dielectric Constant
2014/4/24
Present paper deals with the task of estimating soil moisture under vegetation cover by using transmission line theory based two layer model. The two layer model measures the impedance of both the lay...
RETRIEVING SURFACE SOIL MOISTURE FROM MODIS AND AMSR-E DATA: A CASE STUDY IN TAIWAN
MODIS data Surface soil moisture Taiwan
2014/4/28
Soil moisture is a key factor that controls the exchange of water between land surface evaporation and plant transpiration. Information on surface soil moisture variations in both time and spatial dom...

Dry matter partitioning and physiological responses of Coffea arabica varieties to soil moisture deficit stress at the seedling stage in Southwest Ethiopia
Leaf chemical contents morphological responses
2011/1/12
Dry matter partitioning, leaf chemical contents and morpho-physiological responses of six Coffea arabica varieties were tested in 15 and 30 days water stress followed by 15 days re-watering at seedlin...
Study for the Effect of Soil Moisture Content on the Agricultural Vegetation Using Active Microwave Remote Sensing
Active Microwave Remote Sensing Back Scattering Coefficient Soil Moisture Content Vegetation Small Perturbation Model
2016/4/8
Dielectric constant values of the samples of soil of Alwar (at various moist states) have been calculated using wave guide cell method at a single microwave frequency 9.78 GHz at 330C. The Backscatter...
Evaluation of AMSR-E Soil Moisture Product as an Input to Climate Change Models
Soil Moisture AMSR-E, NDVI
2016/4/8
Present study is an attempt to examine the suitability of soil moisture products available from Aqua-AMSR-E for their application in monsoon simulations at different temporal scales ranging from mediu...
Soil moisture and its consequences under different management in a six year old hedged agroforestry demonstration plot in semi-arid Kenya, for two successive contrasting seasons
Agroforestry demonstrations hedges intercropping Kenya semi-arid land
2009/3/3
Hedged agroforestry (AF) demonstration plots with maize/bean intercrops were studied at Matanya in Laikipia district, Kenya, between 1991 and 1995 inclusive, to understand crop yield behaviour due to ...
