      To use the calculator:      
      Enter desired nutrient rates and number of acres in the yellow cells      
      To calculate a blended price per tonne, enter quoted prices in the green squares    
      The chart will update automatically    
      For micronutrient calculations:    
      Complete the section with the red outlined cells that look like this one ------>      
      Note that just because two liquid fertilizers will mix together doesn't necessarily mean that it is a good idea to mix them.    
      Liquid fertilizer blends involving micronutrients can result in some very unique messes that may look like shaving cream or axle grease.
      Before blending a truckload, do yourself a favour and mix some up in a quart sealer. Let it sit for a few days to see what happens.  
      Even when the quart sealer test works, blending larger batches can have exciting results. 10-34-0 can be particularly problematic  
      in a multi-nutrient micro blend.
