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 1Basics
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
B - Measurement of Volumetric Soil Water Content
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.
1. Xylem water column in a plant is always under tension
2. When cut, water column retreats into leaf
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.

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).

Irrigation Automation

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

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.

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).

scheduling according to field capacity concepts, studies about deep percolation and similar tasks. ECH2O Sensors are available in various models, offering many fascinating options.
Models EC-5 and HS-10 offer measurement of volumetric soil water content with highest accuracy, model EC-TM measures additionally soil temperature and model EC-TMEC measures
besides soil moisture and soil temperature, electric conductivity of soil additionally. ECH2O probes installed in various soil layers, provide information on soil water dynamics across the
whole profile.
For read out of ECH2O probes, one handheld meter and datalogger are available. Decagon Sensors can be attached to iMetos Stations. Datatrac Software offers multiple options for
data display and data processing for all major soil types and soilless substrates. One of the options provides necessary water applications in mm, thus enabling the user to solidly base
all irrigation decisions.
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
