Our Soil Moisture Management Solution provides a framework to help you find the optimal growing conditions for your crop and look to repeat them. Build knowledge on how your crop uses water and the most cost effective way to deliver it to the different parts of your farm.
Soil Moisture Application
Our specifically designed Soil Moisture Demand Application provides you and your Agronomist a range of tools designed to allow you to monitor and control your crop’s soil moisture.
The Global soil app map page displays the locations of each probe site with colour coding to represent the current status of the root zone moisture levels. Dark blue indicates current moisture is too high, light blue indicates moisture is above full point, green indicates moisture is within the optimum range, orange indicates moisture is below refill point and red indicates moisture is at a critical low level.
On the right side of the screen, each site is listed with a summary of the current status of moisture that is represented in a colour bar chart as well as the root zone moisture level, represented as a percentage of the moisture reserve available. 100% is full point and refill point is 0%. When moisture levels rise above full point, the values are expressed as numbers above 100% and the bar colure change to light blue. AS moisture levels within the root zone fall below refill point, values are expressed as numbers below 0, and the bar colour changes to orange.
Predicted irrigation dates are also displayed and if moisture levels within the root zone have increased, refill prediction indicates "wetting".
The map page is designed to provide users with a quick reference of all sites, current root zone moisture levels and predicted irrigation dates.
Predicted irrigation dates
From the map page, users are able to edit the time period from which the predicted irrigation dates are calculated. Predicted irrigation dates are based on the rate of root zone moisture decline over a selected period of time; either 24, 48 or 72 hours. Based on the rate of decline, over the selected time period, the program calculates a date at which the root zone moisture will reach the refill point. This is a valuable management tool assisting in timely and accurate irrigation scheduling decisions.
Separate level graph
Data from multi level probes can be viewed as stacked or separate level charts. Below is an example of a separate level chart. Data is displayed on the one scale, allowing users to analyse the moisture distribution down the profile. The separate level chart provides a clear indication of the pattern of water use, the depth of water extraction, the effectiveness of rain and irrigation events.
The alternative chart for plotting data from multi level probes is the stacked chart. This chart displays the moisture levels of each sensor from the surface down. This chart provides a quick reference to the depth of wetting and water use of crops in a simple to view format.
Summary root zone moisture chart
The summary root zone moisture chart displays the weighted average soil moisture of the root zone. The values are displayed as IU's or Irrigation Units, as the probes are not calibrated. This chart is used to view and analyse the root zone moisture content, using the adjustable moisture set points (full, refill and stress) as indicators of plant available water, irrigation and rainfall effectiveness, the impact of prevailing weather conditions and crop stages on plant water use and managing irrigation schedules. Date ranges allow the plotting of charts over different periods of time, with the ability to zoom in and out of selected events.
Additional information on summary screen
In addition to the root zone summary screen, showing moisture management set points, on the left, current values from other sensors that are connected are displayed. This provides a quick view of the current data that has been measured, which can also be plotted on the chart.
Within Global the ET feature uploads evapotranspiration data from the closet BOM weather station site and loads it into a table format that displays daily reference ET and cumulative reference ET. Relevant crop factors can be applied and edited to calculate reference ET as well as cumulative reference ET. Global presents the daily cumulated reference ET to assist with irrigation management.
Summary chart with additional sensors
From within the root zone moisture summary chart, other sensors that are being recorded can also be plotted, either with the soil moisture, individually or overlaid. In the example below, the green line is wind speed, the purple line is relative humidity and the orange line is air temperature. The ability to overlay other data onto the summary root zone moisture chart is useful when analysing such things as the impact of wind speed, air temperature and other weather parameters on plant water use. Other sensors such as pressure and flow can also be recorded in order to monitor the performance of the irrigation system and to cross check the operation of the irrigation and the corresponding effectiveness of irrigation events.
