Basics - Irrigation Scheduling
General

The exact scheduling of irrigation is very important because:
              • Both, too high and too small water applications result in negative effects on yield, plant health and environment.
              • Nutrient availability and uptake are influenced strongly by soil moisture conditions.
              • Each irrigation event is causing cost.

Benefits of exact irrigation scheduling are therefore                        Example: yield-effect of soil water potential in raspberries
                • increased yield
                • improved quality
                • savings in money and natural resources

Necessary for appropriate irrigation scheduling is:
               • exact determination of irrigation frequency
               • exact determination of irrigation water amount

To collect this information, various approaches are common. Following
some background information, these approaches will be discussed briefly.

                            Soil consists of soil particles (mineral or organic) and the soil pores, which are either filled with water or air. Depending
Soil and Soilwater

                            on the average size of soil particles (soil type), structure, compaction and organic matter content, total pore volume greatly
                            varies from soil to soil. Total pore volume is key factor for water storage capacity of any soil.

                            The narrower the diameter of water filled pores, the stronger the force with which water is bound by soil, and plants have
                            to apply more energy to extract it. This force is called soil water potential or soil water suction.

The term fieldcapacity refers to the amount of water a soil can hold back against gravity (the soil water content at a soil water potential of approx.
60 hPa or pF 1,8). Plant usable fieldcapacity is the amount of water, bound in soil with a soil water potential between 60 (pF 1,8) and 15 000 hPa
(pF 4,2), i.e. Plant usable field capacity equals field capacity minus the water, which is bound so strongly in soil, that it can not be taken up by plants
any more. (non plant available water).

Due to above described circumstances the amount of plant available soil water is varying strongly between soils. Example: Plant available water of
a typical sand ranges between approx. 5 and 15% absolute water content, while plant available water of a typical clay soil ranges between approx.
30 and 50% water content.

Irrigation scheduling Approaches

This approach measures the soil water potential as indicator of water availability for plant uptake in soils. Measuring soil water potential provides in-

formation on the force with which water is bound by soil (= energy plants have to apply to extract it), but it gives no information on the amount of
water contained in this soil. Common measurement units for soil water potential are hPa (1 hPa = 1 mbar) and kPa (1 kPa= 1 Centibar = 10 hPa /
mbar).

                     web www.mmm-tech.de                                            eMail info@mmm-tech.de                                               1
Basics
Measuring soil water potential is the classical approach of irrigation scheduling. It is possible to transfer values of soil water potential from soil type
to soil type, i.e. it is of minor importance in which soil a measurement is taken. For example a measured soil water potential of 150 hPa results in
the same information weather this measurement has been taken in a sand or in a clay soil. Clearly defined optimum ranges do exist for all major
crops, and crop development stages, which are valid for all soil types. For best results three measurement sites, each in two depth are recommended
per irrigation unit..

Tensiometer and Watermark Sensor are instruments to measure soil water potential. Tensiometers yield very accurate results in the moist end of
the range (0 to approx. 800 hPa), and are successfully used in almost all growing systems and crops, grown in mineral soil and substrates. Tensio-
meters show best results in drip irrigation systems.

Good irrigation scheduling results in optimal
moisture conditions and nutrient availability in
the whole main root-zone, without losses due to
deep percolation.

                                                    Pictures: blue: - too wet; green - optimal moisture; orange / red - too dry

This approach uses instruments to measure the volumetric water content of soil. It yields information on the total water content, including the not

plant available part of it in a given unit of soil. This approach provides no information on the energy which is necessary to extract water from this soil.
Common units in volumetric measurement are mm, Vol. % or liter of water per liter or m³ of soil

Volumetric measurement values can not be transferred between different soil types. Example: The measurement result of 30% water content would
mean for a sand saturation (soil water potential approx. 10 hPa or pF 1,0), while a silty soil would show a soil water potential of approx. 300 hPa or
pF 2,5. A clay soil at 30% water content would be close to the permanent wilting point (soil water potential approx. 15000 hPa or pF 4,2).

TDR Fieldscout and FDR ECH2O Sensor are instruments to measure the volumetric soil water content. Volumetric probes and measurement in-
struments are the ideal tool to answer the question how much water to apply per gift.

This approach measures directly the leaf- or stem water potential, the tension of the xylem water

in a plant, with a Scholander pressure chamber. It provides direct information on the water status
of a plant, and thus on water availability in the whole rooted zone of this plant. Common measure-
ment units are MPa and bar. (1 MPa = 10 bar)

Values from measurements with a Scholander chamber can be transferred between sites. Clearly
defined optimum ranges do exist mainly for trees and vines. The measuring process itself however
is labour intensive and can not be automated. Scholander chambers are most commonly used in
grape production and research.

The climatic water balance (also Geisenheimer Methode) is an indirect approach. Based on environmental data, the potential evapotranspiration (=
D - Climatic Water Balance

transpiration of plants + evaporation from soil) is calculated for a specific area and time period (most common formula: Penman-Monteith). In a
second step, this value is corrected with an empirical factor Kc (Kc determined by crop and development stage) to the actual evapotranspiration.
Finally eventual rainfall is subtracted.

The climatic water balance yields information on the water loss in mm over a given period of time. The calculation must be performed for every in-
dividual field and crop. For most crops and crop development stages various Kc correction factors do exist. Some of the iMetos automatic weather
station models offer an automated climatic water balance.

IR-P Irrometer®
Unlike other models by Irrometer which are intended for permanent installation, the Model “P” is designed to be installed in a temporary situation so that the user
mobile tensiometer for maximal flexibility
can make a “spot check” of soil water tension and then relocate the instrument to other locations. A reading takes under normal conditions only 5 minutes appro-
ximately. Apart from this, model LT shows identical advantages like the standard model, and is made to meet highest standards.

Watermark
  The use of Watermark Granular Matrix Sensors is specifically recommended for situations with longer time lags between water applications, i.e. in
  General

  situations with higher fluctuation of soil moisture, for example in cases like irrigation by irrigation machines or in crops which need some degree of
  dry stress or which are generally cultivated at the drier end. Besides the read-out equipment by Irrometer, Watermark Sensors also can be easily
  incorporated in complex data collection systems. For details please see chapters Now-SMS and iMetos.

  Watermark Sensors measure soil water potential between 0 and 200 Centibar (0-200 kPa), are maintenance free and frost proof, and are buffered
  Advantages

  against varying salt content (EC value) in soil solution. Interpretation of data is easy, since measurement result is valid for all soil types. Watermark
  Sensors are durable and low cost, offer an accurate measurement result and have been field approved since decades.

  Watermark Sensors consist of two electrodes, which are embedded in a special granular matrix. The sensors are protected by a stainless steel
  Working Principle

  cover. Surrounding soil and the granular matrix inside a Watermark Sensor come to an equilibrium of soil water potential. The granular matrix has
  a varying resistance to electrical power (AC), depending on it’s moisture content. This resistance is converted by the readout meter into soil water
  potential (unit Centibar).

                                                        The Watermark Sensor is a robust, user-friendly sensor, maintenance free, frost proof and buffered against varying salt

                                                        contents of soil solution. The cable can be spliced up to a total length of 100m.
                                                        However its reaction time to soil moisture variations is somewhat slower than tensiometer or volumetric sensors. Interpre-

IRROmesh
wireless mesh network and data-aquisition system for soil moisture, soil temperature and rainfall, which is able to manage
solar powered wireless data-acquisition with intelligent radio communication
up to 20 data-nodes, i.e. up to 60 Watermark Sensors and 20 sensors for soil temperature. Data are available either via a
data logger, or can be transferred to the Irromesh web portal (web portal is free the first month, after this monthly fee ap-
plies).
Each data-node (WM-975-N) is working at the same time as data-acquisition device, transmitter and repeater for other
data-nodes in the mesh system. Its 6 sensor ports are equipped with 3 Watermarks (WM-S), 1 sensor for soil temperature
(WM-BT) as standard. Optionally a rain gauge (WM-975-RG) and a pressure switch for recording irrigation run time (NOS-
DB) can be attached to each node.
The logged data are received by the Irromesh base (WM-975-B) and can be transferred either to a local data logger (WM-
975-L) or via a GSM gateway (WM-975-G) to the Irromesh web portal. If the base of the Irromesh network is in reach of
a computer with internet access, data can also be continuously streamed via PC-link (WM-975-P) to the Irromesh web
portal (WM-975-WEB). The portal offers online data storage, data management and data display in real time and additional
tools. The use of Irromesh web portal is free during the first month, after this, a monthly fee applies (payment: online by
credit-card).
Due to intelligent radio communication the system features:

 SELF-INITIALIZING – Nodes power up with initial sun exposure and associate themselves with the base receiver
                                                                                                                                200 ha max.
 SELF-ROUTING – Nodes route communication for maximum efficiency
 SELF-HEALING – Nodes will re-route themselves in case of network obstruction or interference.
 AUTOMATICALLY MANAGES POWER – Data transfer frequency reduces under no light conditions and will re-establish itself with sufficient sunlight

Irrigation Automation
Time savings and simplified management are the central advantages of Irrigation automation. If an Irrigation controller or an electro-valve is equipped
General
with an automatic switch unit based on a sensor for soil or substrate, the crop is allways optimally irrigated but unnecessary and potentially costly
water applications are not taking place.
Depending on the availability or absence of electrical power on site and the type of soil moisture based switch unit the use of an irrigation controller
is optional or necessary. A professionally planned irrigation automation based on soil- or substrate moisture consists of the elements Soil moisture
based switch unit, electro valve and irrigation controller (in some situations not compulsory).

A - Mode of operation - with irrigation                                                           B - Mode of operation - direct control
The irrigation controller is programmed on a time based schedule, for exaple irrigation 4         The switch Tensiometer permanently controls the water availabilty in soil or substrate, and
controller                                                                                        with switch Tensiometer (24V AC only)
times per day for 15 minutes. If a soil moisture based switch unit is present, the irrigation     is wired to the electro valve. At a certain point of water availabilty or soil moisture potetianl,
controller checks every time before a water application is allowed the status of soil moisture.   the switch point, an electrical contact is closed, and the electric valve is supplied with power,
In case the soil or substrate is still wet enough this individual irrigation event is blocked,    and opens the water flow. As soon as the soil moisture potential is again below the switch
and does not take place. The system waits in this situation until the next water application      point, the valve closes again. A central advantage of this technique are low cost and a
is scheduled, when this routine is repeated.                                                      straight foreward apporach.

Automation WITHOUT electric power on site
Without electric power on site, only electro valves with latching solenoid can be used, since this type can be operated by battery power. To operate a latching solenoid an irrigation
controller is compulsory, since it creates the electrical impulse, which opens and closes the valve. Many battery operated irrigation controllers are equipped with a sensor port for soil
moisture based automation.

Automation WITH electric power on site
In case electric power (220 V AC) on site is available (i.e. Greenhouse, many lawn & garden applications) an alternative to the use of an irrigation controller does exist, the direct control,
because standard electro valves with solenoid can be directly controlled by switch Tensiometers and Now_SMS units.
In any case the electric voltage is reduced by a transformer to safe 12 or 24 VAC.

Watermark Switch Units
Watermark Switch Units are designed to control irrigation controllers with sensor-port. Only if the soil is dryer than a threshold set by the user at the Watermark Switch Unit, an irrigation
maintenance free Irrigation Automation
event is taking place. Prevents unnecessary irrigation events, saves water and energy.
The Watermark Switch Units are available in two series: Water Switch and Watermark Electronic Modules. Water Switch offer economic irrigation control based on one Watermark
Sensor and are used in golf, lawn and garden applications, the Watermark Electronic Modules offer irrigation control based on the average reading of two Watermark Sensors, and are
common in more complex systems.

Water Switch
Both Water Switch Models are „Dry Contact Switch“ units, and are connected to the Sensor-port of an Irrigation controller. The Waterswitch units check the soil moisture status
the economic solution
independently every hour (WS) or every 5 minutes (WS-B) and switch the sensor – port according to soil moisture. Waterswitch units can be used with both types of Irrigation controllers,
normally open and also normally closed contact models.

Watermark Electronic Module
Watermark Electronic Modules are available in three models. Models WEM-B and WEM-DC-T are „Dry Contact Switch“ units, and are connected to the Sensor-port of an Irrigation

controller. The models WEM-B and WEM-DC-T check the status of soil moisture independently every 5 minutes, and set the sensor – port according to soil moisture.
The Watermark Electronic Module model WEM is a „Common Interrupt“ switch unit, and can switch a single valve or group of valves on a dedicated common. The unit reads itself only
when powered (start time) and switches according to moisture in relation to switch position. The Watermark Electronic Modules Type WEM and WEM-B can be used with both types of
Irrigation controllers, normally open and also normally closed contact models, while type WEM-DC-T needs a normally open contact.

Volumetry - TDR / FDR
Volumetric Measuring Instruments determine the Water Content in Soils, and inform the user about the amount of water, which is presently contained
General
in soil. The shown amount of water in soil includes the non plant available part.
These Sensors are ideal to answer the question how much water needs to be applied, to fill the rooted soil-profile from the presently measured state
to a defined volumetric percentage of field capacity (for example to 90% field capacity).

     • information about the amount of water in soil
Advantages
     • very accurate technique
     • immediate reaction on changing soil moistures
     • maintenance free and frost proof sensors

TDR Fieldscout - highly accurate, fully mobile, integrated Datalogger
TDR Fieldscouts are fully mobile measuring instruments for soil water content, EC value and soil surface temperature. No permanent sensor instal-
lation necessary, no valuable equipment remains in field. Multiple field points or a multitude of different fields can be measured. One measurement
takes only seconds: prick measurement rods fully in ground, push button to take the measurement, go to next measuring point!
Working Principle TDR
TDR (Time Domain Reflectometry) Sensors determine the soil water content by measuring the dielectric properties of the soil along two (or more) measuring rods. The travel time of an
electromagnetic impulse emitted by the instrument is determined by the dielectric properties of soil , and thus it’s water content. The measurement shows the average water content of
the measured soil profile, which equals the length of the measuring rods presently in use.
Calibration
Three calibrations already programmed in the firmware of the instrument: Standard (for most soils), sand and high clay (for soils with clay contents of 30% or more).

Working Principle FDR / Capacitance
FDR (Frequency Domain Reflectometry) Sensors measure the soil water content via the dielectric properties of the soil between two electrodes by capacitance. The read-out device
checks the „echo“ of an electro-magnetic impulse sent to the surrounding soil for frequency variations and thus determines the water content of the soil. .
Typical Applications: strawberry and softfruit, vegetables, asparagus, fruit trees, hops, vineyards, potatoes, sugar beets, arable agriculture and seed production, scientific applications
in open field and protected cultivation. Use in grown soil and soilless substrates
