It's the time of year when we can start to look at Fertilizer by Management Zone. We can start at the simplest spot by creating a Management Zone based off Soil Type or Slope, or we can take normalized yield and create a Management Zone based off that. 

From there you have a couple options:

1. Direct Application by Zone  

2. Recommendation based on Equation

For the equation you could apply your Gold rec to the A zones, the Silver rec to the B zones and Bronze to the C zones. These are your equations and can be set up to your desire.  

In the management zone screen you can also assign seeding rates that can be used as prescription files. We have a seed database so almost any seed variety can be used.   

The nutrient constraints tab can be intimidating, but it's also a very powerful tool. It's always interesting to see the different scenarios come through.    These can also be saved as templates for future use.      

Here is an example where the agronomist wanted to put on 2 Tons of ECCE where the equation called for 2 Tons or greater.  In the areas where it was less than 2 Tons nothing was applied.

Syntax in Nutrient Constraints tab would look like this:

Did you know there is a iPad app for SOILMAP?
