Page 11: Usage Information
1215PK - Wireless Soil Moisture Pack Usage Information This Wireless Soil Moisture Sensor is designed to give accurate evaluations of soil moisture and to report these in a simple to understand format. Water in the liquid state, has a high capacitance and consequently the dielectric constant of it compared to free space is about eighty times. -
Page 12: Calibration Options
1215PK - Wireless Soil Moisture Pack readings. Appreciation of soil composition, its performance and how that is to be assessed should be considered before measurements are gathered. For example, a highly absorbent soil, such as clay may well accept a large volume of water, but it may not do so quickly. Sand, on the other hand, will not be so accommodating for water, but will absorb (and drain) in a shorter time. - Page 13 1215PK - Wireless Soil Moisture Pack 13 / 26 | Revision: 0 | DS194...

Page 14: Data Collection
1215PK - Wireless Soil Moisture Pack Data Collection Please consider how the probe is to be presented to the sample, dependent upon the type of investigation required. The probe can be positioned vertically with respect to the soil's surface, for average moisture values or values that represent the moisture at a defined depth. - Page 15 1215PK - Wireless Soil Moisture Pack Definitions The ability of soil to aerate, provide nutrients to crops, and influence the dampness of a target crop is affected by the soil water content. This unit has the capability to generate calibration, with a specific sample. The choice of reporting output between VWC and GWC is achieved by a simple linear conversion.
- Page 16 1215PK - Wireless Soil Moisture Pack Additional Information There are several key definitions and concepts that are related to soil moisture, and they are briefly explored here. Soil Saturation Field Capacity (FC) Permanent Wilting Point (PWP) Soil Saturation In this state, the soil voids have been filled with water.
- Page 17 1215PK - Wireless Soil Moisture Pack Soil Matrix Potential (SMP) The SMP is a measure of the soil water tension, and plants must exert a force greater than this to extract water from the soil. As water declines in the soil, the SMP increases - so there is a relationship between % VWC and SMP.
