SoilMate - Key Tools available to support you out in the field

12 February 2015

Back Paddock is pleased to be able to offer SoilMate Tools to further support you in your activities – these tools are exclusively available only to our SoilMate licence holders.  

To access these tools

  1.  Log into SoilMate
  2. On the side menu – click SoilMate Tools
  3. Click on the specific tool you are selecting to use.


  4. a.    Yield or Protein – Wheat

    This spreadsheet was developed to help explore the decisions when choosing between wheat variety on the basis of increase yield potential but with a potential grain protein penalty or whether to go for a higher protein variety that may have a lower yield potential. The outputs of this spreadsheet are the grain premiums that would be needed to justify not targeting for higher yield potential from another variety.  Click on the calculator tab to perform your analysis.

    b.    LimeMate

    LimeMate calculator is in two parts:-

    Part one is LimeMate which an aid in the calculation of  rates of soil amendment require to increase soil pH based on  a combination of  measured soil chemical parameters, soil chemistry targets, plant species aluminium tolerance and amendment quality. The amendment rate suggested is the greater of the rate require to reduce the soil aluminium saturation to a point where the production of the target species is unlikely to inhibited, or the rate required to raise the pH from the current level to a nominated target pH.

    Part two is Product Comparison aids in the calculating the most cost effective source of amendment when there are multiple sources available. Recommended product is  based on assessment of a combination of product effectiveness characteristics, soil targets and costs.

    c.     Ram Dalal’s Rule of Thumb

    Rams "Rule of Thumb" calculator is based on research that relates soil water and nitate-N content measure at sowing to likely grain protein outcome.  It is only valid for grain production regions of southern Queensland and NW NSW and soils sampled to depths greater than 60 cm. To use this calculator will you need to input a reasonable reliable estimate or measurement of available soil water (mm), soil nitrate-N (kg/ha) to a measured soil depth.  The output is a graph that shows the likely grain protein % outcomes for a range of soil nitrate- N contents at single soil moisture. This graph can be used to estimate the quantity of N required to change grain protein.

    d.    Wheat Plant Tissue Interpreter

    Wheat Plant Tissue Interpreter is designed to help with the interpretation of plant nutrition status according to its nutrient content of and its phenlological growth stage.  The algorithms relating growth stage and nutrient status have been derived from a wide range of data sources including Reuter and Robinson (1997), Weier and Creswell (1994).

    e.     Anthesis Foliar Urea Calculator for Wheat

    This spreadsheet can be used to help assess the economic risk associated with applying a foliar application of urea around anthesis in wheat to increase grain protein %. This outcome is based on the user’s assessment of current yield and grain protein potential and differences in grain prices for increased protein content.  Data and suggestions contained in this calculator are based on research from North America and Europe and are as yet to be confirmed in Australia.
