Soil Moisture Sensors that tell you WHEN and HOW MUCH to irrigate |
Calafrica SA, suppliers of Irrometers, Tensiometers, Watermark, electrical resistance granular matrix sensors for Soil Moisture Measurement and Soil Moisture Sensors for Agriculture and Landscaping |
IRROMETERS |
WATERMARK |
 |
 |
An IRROMETER ® is a Direct Measurement System, which means that it actually reads the physical forces at work in the soil. Irrometers act like a dummy root, allowing the soil moisture to interact with the instrument through the ceramic tip.
Products include :
- Tensiometers
- Soil Suction Tubes
- Gauges
- Electronic Gauge
- Automatic Gauge
- Remote Sensing unit
- Service Units
|
The WATERMARK SENSOR SYSTEM is an Indirect Method of measuring soil water tension. These Sensors electronically read the amount of moisture absorbed through a special mix of precisely composed materials.
These sensors are:
- maintenance free
- can be left in the ground permanently
- have an expected life of 5+ years.
Watermark Sensors (Soil Moisture Sensors) require very little power to read and integrate perfectly with electronic systems for data logging. |

Where Irrigation Decisions should be made ……………… in the root zone! |
| |
Catering to the agricultural, landscape and environmental markets. |
 |
Any irrigation system should incorporate soil moisture indicators to aid in making irrigation scheduling decisions. |
In production agriculture, the use of soil moisture based irrigation scheduling, provides a farmer with site-specific measurements of soil water status in the specific field, specific soils, specific irrigation method, and specific crop, as well as the site-specific microclimate.
|
IRROMETERS® :
- sealed water filled tube
- vacuum gauge and porous tip
- works in MOST soil types
- no calibration necessary
- is in effect a "dummy root"
|
 |
|
The proper use of this information results in IRRIGATION SCHEDULING MANAGEMENT PROGRAMS which result in :
- greater production
- better quality
- less water, energy and fertilizer use
- helps protect water quality by eliminating run off and deep percolation loss of water due to over irrigation.
IRROMETER® AND WATERMARK products both :
- evaluate water use
- evaluate soil moisture in any soil type
- evaluate penetration of water into soil
- prevent water wastage
|
WATERMARK SENSORS : |
-
Solid state, electrical resistance type sensor
-
no water or vacuum gauge
-
works in ALL soil types
-
compensates for varying salinity levels
-
extended range of Data Loggers and Transmitters available
