1.1. Products & Services ProductionWise速 This innovative online crop management tool for rural landholders and advisers helps growers enhance their farm efficiency through access to advanced decision support tools. ProductionWise provides an online paddock and silo record keeping diary in addition to functionality that maps and details paddock and grain storage characteristics, rainfall forecasting and paddock specific soil moisture, APSIM yield modelling, satellite biomass tracking, plus much more.
SprayWise Decisions速 Sponsored by Nufarm, this online system assists rural landholders and contractors to better plan and match the timing of pesticide applications to prevailing local weather conditions. This service provides 1km resolution weather forecasts for your farm out to 14 days through a spray planner diary, meteograms, maps and animations, and allows you to best plan your spray applications for the week ahead.
CottonMap CottonMap is an industry initiative which has been designed to highlight the location of cotton fields. The service is provided free of charge with the purpose of minimising off-target damage from downwind pesticide application, particularly during fallow spraying. The map is a joint collaboration between Cotton Australia, Cotton Research and Development Corporation (CRDC), Grains Research and Development Corporation (GRDC) and Nufarm Australia Limited, developed by GrainGrowers to meet industry needs.

2. Executive Summary This PropertyWise report for the Riversedge property in the Narrabri (A) Local Government Area (LGA) of New South Wales provides an analysis and evaluation of historical climate, production and satellite biometric data. Methods used to analyse the data include trends, annual rate of change, variability, productivity rating, departure from median and percentiles ranked against all other Local Government Areas within Australia. The results from the data analysis show that the Summer season has the highest productivity rating for crop and pasture production and Cotton is the safest crop to grow. Alternatively the safest crop for the Winter season is Wheat. The productive potential indicators for Riversedge are;
Seasonal Climate Productivity Rating* Season Winter Summer

PYCAL is a water limited, maximum potential yield calculation. It incorporates estimated soil moisture at sowing, growing season rainfall, evaporation losses and water use efficiency inputs to determine the likely wheat yield potential assuming nutrient, pest, weed and disease stresses are managed correctly. It provides a way to assess the impacts of seasonal rainfall changes against potential winter crop production.

12. Biomass Production Profile The following chart depicts the variable seasonal conditions and biomass regimes from moderate resolution satellite imagery (LP DAAC, 2011). Calculated from a 10-day (decadal) time step averaged Normalised Difference Vegetation Index (NDVI) each year for the specified location back to 2001. It represents a starting point for assessing the overall productive potential of a farm enterprise. It is also a guide to crop and pasture growing seasons, operational management opportunities and constraints.
How to Read the Biomass Charts There are three major components that make up the Annual Biomass Profile chart. Understanding how to read them together is necessary to getting the most out of the chart. Rainfall The chart displays the monthly average rainfall calculated from 1955. Ideally rainfall should peak during the growing season(s) for your location which are defined by the peak(s) in biomass. Biomass (NDVI) The 10th, median and 90th percentile biomass values are calculated from over 10 years of satellite data for the specified location and averaged to profile annual and seasonal farm biomass. Biomass values greater than 0.6 indicate significant crop or pasture ground cover, values between 0.4 and 0.6 indicate early crop growth or sparse vegetation. Values less than 0.4 are indicative of bare ground or stubble. The variations between the 10th and 90th percentile lines indicate the potential seasonal variation between poor and good years. Temperature Max and min temperature probabilities are displayed as indicators of summer and winter cropping windows. For example, the winter sowing window falls between the points where max temp drops below 0.1 and before min temp reaches 0.1. Winter crop senescence begins when max temp increases above 0.1. Flowering should occur when there is neither a risk of max or min temp greater than 0.1.

Your farm is compared against the LGA average it falls within and the nearest neighbouring LGA.

14.3. Crop and Pasture Windows The Crop and Pasture Windows table uses moderate resolution satellite imagery since 2001 (LP DAAC, 2011), and a computed Normalised Difference Vegetation Index (NDVI) to determine the variation in crop and pasture windows for both the summer and winter seasons. The windows are defined by the duration of the window in days and rainfall received during the window. For each window the table displays the average, minimum (Min) and maximum (Max) range of values likely to be experienced. A rating is determined for each of the windows and yield potential to provide a final productivity assessment of the growing season segment. The rating is calculated between 0-1, with 1 being the highest productivity. Crop and Pasture Windows Planting Window Unit Winter Average Min Max Rating Summer Average Min Max Rating
