soil profile before it can be used by crops.
Matric potential - A negative pressure or suction head that is read by SMS and reflects the ability of soil to either retain or move water as a result of suction exerted by soil pores.
Oscillator - A device that converts direct current (DC) from a power supply to an alternating current (AC) signal.
Runoff - Water that originates from landscapes during precipitation/irrigation events that does not infiltrate into the soil.
Volumetric - A unit of measurement in which the water in a soil is described by the percent volume of the space that the water is occupying.
Water use efficiency - Percentage of applied water used by the intended plant.
Soil moisture sensors - Devices that are used to measure water content of a soil by various techniques.
Soil texture - Composition of soil based on its particle sizes. Volumetric - A unit of measurement in which the water in a soil is described by the percent volume of the space that the water is occupying.
Voltage - Difference of potential energy between two points on a circuit. Water use efficiency - Percentage of applied water used by the intended plant.
