\subsection{Skill Building} \label{subsec:Skill_Building_4}
This exercise begins with a winter wheat management template.
The user will utilize a simple one year rotation
to understand how desired yields can be achieved with the implementation of irrigation.

\subsection{Scenario} \label{subsec:Scenario_4}

\begin{itemize}

\item{The field is located in \textbf{Elmore county, Idaho.}}
\item{The field shape is a \textbf{120 acre circle}.}
\item{Manually enter latitude and longitude.
Set the latitude as \textbf{43.26946\textdegree\ N} and longitude as \textbf{115.95191\textdegree\ W}}.
\item{The \textbf{Cligen} station is \textbf{Boise Lucky Peak DM}.}
\item{The \textbf{Windgen} station is \textbf{Mountain Home AFB}.}
\item{The cropping system is \textbf{wheat, winter, early plant, med residue, fdisk, Z11}.
We will cover how to find this management file in the steps below.}
\item{The soil map unit is \textbf{Toll{\_}ID685{\_}2402{\_}85{\_}LS.}}

\end{itemize}

\subsection{Complete the following steps:} \label{subsec:Complete the following steps_4}

\textbf{Step 1:} Enter the region shape and field size as shown in (\cref{fig:The_WEPS_interface_set_with_the_basic_information_for_Exercise_4}). 

\textbf{Step 2:} Select \textbf{IDAHO} for the State and \textbf{ELMO} for the county in the Location panel.

\textbf{Step 2a:} Click \textbf{Please Select Field Location}
and set the WEPS Map Viewer zoom level to \textbf{60\%}.
On the main WEPS interface screen,
set the latitude as \textbf{43.26946\textdegree\ N} and longitude as \textbf{115.95191\textdegree\ W}.
The Map Viewer display should automatically update and show the red "\textcolor{red}{+}" character
within the desired circular field site as shown in
\cref{fig:WEPS_Map_Viewer_displaying_selected_field_site}.

\begin{figure}[H]

	\includegraphics[scale=1.47]{images/Examples_3_4/field_site_ex_4.jpg}
\caption{WEPS Map Viewer displaying selected field site.}
\label{fig:WEPS_Map_Viewer_displaying_selected_field_site}
\end{figure}

\textbf{Step 2b:} Set the zoom level to \textbf{50\%} for the \textbf{WEPS Map Viewer}.
Then select (enable) the \textbf{NRCS CMZ regions}, \textbf{Cligen stations}, \textbf{Windgen stations}
and \textbf{Cligen boundary} layers,
while disabling the \textbf{Imagery ArcGis} layer.
Notice that this area is within \textbf{NRCS Crop Management Zone (CMZ) region 11}
(\cref{fig:WEPS_Map_Viewer_displaying_NRCS_CMZ_regions_Windgen_stations_and_Cligen_stations}).
It will also be using the \textbf{BOISE LUCKY PEAK DM} Cligen station
(Cligen boundary lines are shown in \textbf{\color{blue}{blue}} on the map).
In addition, it will also be using the nearest Windgen station \textbf{MOUNTAIN HOME AFB} as also shown in
\cref{fig:WEPS_Map_Viewer_displaying_NRCS_CMZ_regions_Windgen_stations_and_Cligen_stations}.

\label{fig:WEPS_Map_Viewer_displaying_NRCS_CMZ_regions_Windgen_stations_and_Cligen_stations}
\end{figure}

\textbf{Step 3:} Select an NRCS CMZ management template
by clicking the ‘Man’ dropdown button {\scalerel*{\includegraphics{images/icons/down_arrow.png}}{\strut}
to the lower right of the screen.
Click \textbf{‘CRLMOD Managements’}, scroll down and select CMZ 11.
From the CMZ 11 drop-down, select \textbf{Single year single crop treatments}.
From this list, select the \textbf{Wheat, winter, early plant, medium residue, fdisk, Z11} management
\cref{fig:Selecting_mgt_from_CSIP_CMZ_Service}. 
 
\begin{figure}[H]

\caption{Selecting CMZ management template from CSIP CRLMOD Managements Service.}
\label{fig:Selecting_mgt_from_CSIP_CMZ_Service}
\end{figure}

\textbf{Step 4:} Choose the soil from the CSIP Soil Service as seen in \cref{fig:Selecting_Soil_from_CSIP_Soil_Service}  


\begin{figure}[H]

	\includegraphics[scale=1.7]{images/Examples_3_4/soil_type_ex_4.jpg}
\caption{Selecting soil from CSIP Soil Service.}
\label{fig:Selecting_Soil_from_CSIP_Soil_Service}
\end{figure}


\textbf{Step 5:} Before we execute a run, we are going to edit the management template.
Open MCREW, then edit and add operations so that the management file matches
\cref{fig:Editing_Management_Template_in_MCREW}.
\textbf{Set the Harvest Target yield for wheat to 80 bu/ac.}
Save the management file to a new name that indicates it was modified.
Now, execute a \textbf{Yield Calibration Run} {\scalerel*{\includegraphics{images/icons/calibraterun.png}}{\strut}.
 
\begin{figure}[H]
\centering
	\includegraphics[scale=1.28]{images/Examples_3_4/MCREW_EX_4.jpg}
\caption{Editing Management Templates in MCREW.}
\label{fig:Editing_Management_Template_in_MCREW}
\end{figure}

You will notice when you execute a calibrated run that the Biomass Adjustment Factor is \textbf{3.328} (\cref{fig:Editing_Management_Template_in_MCREW}). This is well outside of the recommended 0.5-2.0 range, and should raise the suspicion that some WEPS input was incorrect. 

\begin{figure}[H]

	\includegraphics[scale=2]{images/Examples_3_4/biomass_adj_factor_ex4.jpg}
\caption{High Biomass Adjustment Factor for dryland winter wheat.}
\label{fig:Biomass_Adjustment_Factor_for_winter_wheat}
\end{figure}

Looking more closely at the Weather (summary) Tabular Detail Report,
we see that it is improbable that an 80-bushel wheat crop can be produced with no irrigation
in an area that received 11 inches/year on average (\cref{fig:Weather_(summary)_Tabular_Detail_Report}).

\begin{figure}[H]
\centering
	\includegraphics[scale=2]{images/Examples_3_4/weather_tabular_detail_report_ex_4.jpg}
\caption{Weather (summary) Tabular Detail Report.}
\label{fig:Weather_(summary)_Tabular_Detail_Report}
\end{figure}

\textbf{Step 6:} Let’s add irrigation to this management (\cref{fig:MCREW_with_added_irrigation_operations})
and  re-execute the \textbf{Yield Calibration Run}.
It will be assumed that precision soil monitoring
will help the producer accurately apply irrigation water.
To best capture this type of irrigation water management,
we will add the operations \textbf{Irrigation, Start Monitor (pivot, linear, wheeline)}
and \textbf{Irrigation, Stop Monitor} to the management.
Using these managements, irrigation water will be added by WEPS as soil moisture is depleted.
Alternatively, WEPS users have the ability to add single irrigation events to the management,
regardless of the rainfall that occurs in each of the 50 simulations.

\caption{MCREW with added irrigation operations.}
\label{fig:MCREW_with_added_irrigation_operations}
\end{figure}

The \textbf{Biomass Adjustment Factor} drops to \textbf{1.3} when irrigation water is added to the management system (\cref{fig:Biomass_Adjustment_Factor_with_added_irrigation}})


\begin{figure}[H]

	\includegraphics[scale=1.4]{images/Examples_3_4/Biomass_adj_factor_with_irrigation_ex4.jpg}
\caption{Biomass Adjustment Factor with added irrigation.}
\label{fig:Biomass_Adjustment_Factor_with_added_irrigation}
\end{figure}

Also, notice that annual erosion is well below the Soil Loss Tolerance
and the winter wheat yield is 80.3 bu/acre.
