If your site includes slopes, you've probably faced significant irrigation challenges related to the topography. However, if the top, slope, and bottom of the hills are irrigated by different zones, you have the ideal setting for using soil moisture senso...
Installing a soil moisture sensor in a wet climate allows you to conserve water by making better use of effective rainfall. The soil moisture sensor detects the rainfall that reaches the root zone (the "effective" rainfall), and adjusts the irrigation sch...
Soil moisture sensors that are made up largely of metal components are susceptible to damage from lightning strikes even though they are buried. If lightning strikes nearby, currents can travel through the interconnecting wires and damage the sensitive ci...
In a desert climate, the surface of the soil dries out quickly, but adequate moisture is often available in the root zone of adapted plants. If you are serious about conserving water and maintaining healthy plants in a desert climate, a soil moisture sens...
Durability or reliability is arguably the most important factor in a commercially used soil moisture sensor. Baseline has been building soil moisture sensors for over 13 years. Our sensors are used all over the globe -- from Death Valley where soil temper...
Yes. If you are under a watering restriction that allows you to water only one day a week, you have an ideal scenario for using a soil moisture sensor with the upper threshold watering strategy. Suppose your watering day happens to be on a day after a rai...
Baseline's patented soil moisture sensors use TDT (time domain transmission) technology to provide sensors that are so much more sensitive (which means they are highly responsive to changes in moisture levels) than previously available sensors. Baseline s...
The answer depends on what watering strategy you are using: * If you are using the upper threshold watering strategy, the sensor will monitor the moisture level of the soil and then decrease or increase the zone's defined run time based on the upper m...
The dimensions of the area that Baseline's soil moisture sensor reads will vary depending on factors that affect electrical conductivity such as soil type, compaction, the amount of moisture in the soil, and whether there are any additives in the soil. ...
Successful irrigation management is knowing when to turn the water on and when to turn the water off in order to use the least amount of water possible to keep the soil moisture content in the root zone at the appropriate levels. A properly placed and c...
Choose the zone that needs to be watered the most frequently. Place the sensor within that zone, in an area that receives average to slightly less than average water from the irrigation system. Place the sensor in an average to slightly dry area (a spot...
Bury the sensor in the center of the effective root zone of a typical plant in the area that the sensor will monitor. The effective root zone of a plant is the top third of the root structure where the roots are dense. The sensor depth varies depending ...
When we see a plant in the landscape that is doing poorly, we often assume that it's not getting enough water, and if the poor-looking plant is located near other healthy plants, it's typical to assume that the water-holding issues are due to variations i...
While it's true that many soil moisture sensors on the market aren't effective in heavy clay or sand, Baseline's patented TDT technology enables our sensors to detect minute moisture level changes in all types of soil. Our sensor's responsiveness coupled ...
The actual answer depends on many factors such as how your irrigation system is configured, how your hydrozones are laid out, what kind of topography your site has, the variety of plant material that you have, and what kind of use your site gets. Consid...
No. If the irrigation system is two-wire, connect the sensor to the closest two-wire path. If the system is conventional wire, connect the sensor to the nearest valve. Refer to the biSensor Installation Guide. [http://www.baselinesystems.com/mediafiles/...
You can think of the soil moisture sensor as the thermometer on your home's thermostat. It's likely that you use one thermostat to control the heating and cooling in your entire home based on the temperature measured at a single location. If you have bu...
Obviously, the sensor will detect the increased soil moisture caused by rain. However, because it takes time for the rain water to reach the sensor, the sensor reading typically will not cause the system to shut off quickly during a rain event. If you wan...
Baseline recommends that you establish a standard installation method for all your biSensors. A suggestion is to install the sensor 3 to 6 feet from the valve box where the sensor is connected to the irrigation wire path. If possible, orient each sensor i...
If your soil amendments require aeration before/after they are applied, Baseline recommends that you dig up the sensor. Complete the soil amendment procedure, and then rebury the sensor.
Some customers have buried a length of rebar along the top of the biSensor to protect it from being hit by aerator tines or a shovel. Make sure the rebar is positioned at least 1 inch above the sensor. Align the rebar with the sensor blade and the sensor ...
Always remember that the smallest area the controller can manage is a zone. If you have a dry or wet zone, you can adjust it in several ways from the controller, but if you have a wet or dry spot inside the zone, you can either choose to fix whatever is c...
Remember that there are really only two decisions you need to make irrigating: when/how often to turn on the sprinklers and how long to run/when to shut off the sprinklers. You can use a soil moisture sensor or a weather station to automate these decision...
Yes. You can use Baseline's biSensor to monitor the water level in a pond, cistern, or water feature, and then tell the controller to refill that water source when the water level gets too low. If you are irrigating from that water source, you can also sh...
