1.Click the in the Fertilizer Planned table.

2.A box will appear allowing you to choose either a fertilizer from a drop-down list or create a new one.

3.To create a new fertilizer, select the <new fertilizer> option and click OK. Note that if you are looking to mark a fertilizer as either slow release or as a nitrification inhibitor, you will need to do so by creating a new fertilizer. See Using Slow Release and Nitrification Inhibitor Fertilizers for more information.

4.A window resembling the screen shot below will appear.

The first step is to identify whether the fertilizer is a dry or liquid type.

New Fertilizer: Dry

For a dry fertilizer, select This fertilizer is: Dry and fill out the rest of the form with the appropriate information and click OK to create your dry fertilizer. Each part of the box is described below to help you in filling the window out.

Enter fertilizer name: This is where you can enter any name that will help you recognize this fertilizer.

Select default formulation: You can choose shared fertilizers from the drop down list to get you started with an analysis.

%N, %P2O5, and %K2O: This is where you put in the analysis values for %N, %P2O5, and %K2O. These are bold because they are required to be entered for each fertilizer.

%S, %Mg, and %Ca: This is where you put in the analysis values for %S, %Mg, and %Ca. SnapPlus does not currently use these in any calculations, so they are not required to be entered, but you may enter them for your own record-keeping purposes.

N03 Inh:  This is where you can indicate that a new fertilizer is a nitrification inhibitor with ammonium forms of N.

SR: This is where you can indicate that a new dry fertilizer is slow release.

New Fertilizer: Liquid

Select This fertilizer is: Liquid and fill out the rest of the form with the appropriate information and click OK to create your liquid fertilizer. Each part of the box is described below to help you in filling the window out.

Enter fertilizer name: This is where you can enter any name that will help you recognize this fertilizer.

Select default formulation: You can choose shared fertilizers from the dropdown list to get you started with an analysis.

%N, %P2O5, and %K2O: This is where you put in the analysis values for %N, %P2O5, and %K2O. These are bold because they are required to be entered for each fertilizer.

%S, %Mg, and %Ca: This is where you put in the analysis values for %S, %Mg, and %Ca. SnapPlus does not currently use these in any calculations, so they are not required to be entered, but you may enter them for your own record-keeping purposes.

Density: This is where you can put in your liquid fertilizer density value (lbs/gallon). It is bold because it is required to be entered for every fertilizer.

N03 Inh:  This is where you can indicate that a new fertilizer is a nitrification inhibitor with ammonium forms of N.

When dealing with high permeability soils, rock soils with less than 20 inches to bedrock, or wet soils with less than 12 inches to apparent water table, you may want to use slow or controlled release N fertilizers or use nitrification inhibitors with ammonium forms of N. In the Adding Dry Fertilizers and Adding Liquid Fertilizers sections above, the process of adding a new fertilizer and designating it as SR or a fertilizer that will be used with a nitrification inhibitor (N03 Inh) is outlined. On the Nutrients tab, you can see which fertilizers will be used with N03 Inhibitors or are Slow Release by looking at the N03 Inh. and SR columns in the Dry/Liquid Planned Fertilizer table. The fertilizers outlined in red in the screen shot below are good examples.

Note that these are read only columns. You will not be able to mark existing fertilizers as either N03 Inhibitors or Slow Release. You MUST create new fertilizers to mark them as such.
