1. No matter what type of analysis is done there are several steps which are common These will be described here Updating weather data using Met Man Met Man is a separate program which you start from within MaizeMan by selecting the Reference Weather menu option You will see a screen similar to the one below The current station may be different it will depend on what paddock is active when you enter Met Man 22 ig Met Man weather data editor 1 0 70 Io Station Data Help Exit Current station 7 iforial You are in tutorial mode data will not be saved to the database If the current station is not set to tutorial then select Station Select from the menu options i Select the weather station a E CSIRO Guh NEM n CSIRO Hap NSW CSIRO Finley CSIRO Tullakool Tutorial Wagga Airport steele Dalby Narrabri Condoblin Cancel Click the Tutorial option and then click the Use this station button You may also double click a station to select it Met Man s main purpose is to help you import weather data into the database These data can come from a number of different sources 1 Comma delimited text files in the CSIRO format Limited to the four NSW sites at Griffith Finley Hay and Tullakool maintained by CSIRO Land and Water Griffith 2 The same format as above but straight from their web site http www clw csiro au services weather Data 3 Data supplied from the SILO projec2. i CSIRO MaizeMan User Manual Version 3 August 2003 By R J G White E Humphreys E Xevi D C Godwin and D J Smith IRRIGATED CROPPING FORUM CSIRO Land and Water Griffith Technical Report 51 02 August 2003 CSIRO LAND and WATER MaizeMan User Manual Version 1 3 August 2003 R J G White E Humphreys E Xevi D C Godwin and D J Smith IRRIGATED CROPPING FORUM CSIRO Land and Water Technical Report 51 02 2002 CSIRO To the extent permitted by law all rights are reserved and no part of this publication covered by copyright may be reproduced or copied in any form or by any means except with the written permission of CSIRO Land and Water Important Disclaimer CSIRO Land and Water advises that the information contained in this publication comprises general statements based on scientific research The reader is advised and needs to be aware that such information may be incomplete or unable to be used in any specific situation No reliance or actions must therefore be made on that information without seeking prior expert professional scientific and technical advice To the extent permitted by law CSIRO Land and Water including its employees and consultants excludes all liability to any person for any consequences including but not limited to all losses damages costs expenses and any other compensation arising directly or indirectly from using this publication in part or in whole and any info

4. PAW is the amount of water in the profile between the drained upper and lower limits The value increases over time as the crop grows and the roots extend deeper into the profile and water at depth becomes available However once the soil has dried down so that about only half the plant available water is left in the soil it becomes increasingly difficult for the plant to extract this water and the plant has to put more energy into extracting the water and less into growing impairing yield Crops start to experience water deficit stress when the soil dries down to around 50 PAW the exact point varies with the crop weather and other factors The cyan line at the top represents saturated soil The water between saturation and the drained upper limit is not considered as plant available water as it will normally rapidly drain out of the profile due to gravity before the crop can use it Furthermore when the soil is saturated the plants experience aeration waterlogging stress and their ability to take up water is impaired In the above example MaizeMan has been set to recommend irrigating when the soil water content has declined to 50 of PAW The zig zag line is the actual amount of plant availabe water in the soil which changes in response to irrigation rain and crop water use In this example the grower has generally done a good job keeping the crop in the green i e keeping the available soil water content the green line above the c
