... for this study is typical of the units found in the market place today. This probe has the capability for multi-parameter measurement of temperature (°C), dissolved oxygen (mg/l), conductivity (mmhos/cm), salinity (ppt), pH (units), and depth (meters). It can be preprogrammed for remote data logging, tethered...

... with sodium can be classified into three groups: saline, sodic and saline/sodic. Saline soils have saturated Extract Conductivity (ECse) > 4 mmhos (or mS)/cm, pH < 8.5, and ESP < 15 %. The concentration of soluble salts is sufficient to interfere with vegetation or plant growth. Sodic soils occur...

... is as high as 366 mmhos/cm, where as, the EC of CBM produced water is about 2 mmhos/cm. The ability of cultivars to imbibe water from soil is a function of the soil osmotic potential (OP) (the ability of the soil to release water). The soil osmotic potential is a direct function of the soil moisture EC, so...

... of agricultural soils and is expressed in millimhos (mmhos/cm). At EC's of less than 2 mmhos/cm, salinity effects are not considered detrimental, but the effect becomes more important when measured at 2 to 4 mmhos/cm and may begin to strongly effect plant yields when greater than 4 mmhos/cm. Extract of saturated...

This was to provide a control for minimizing common-mode noise signals that are induced along the transmission line. For the laboratory channel test, we used a 61-m #22 twisted pair cable with foil...
