How do I select the soil test datas units on the Soil Tests panel?
Check the Levels Are In Lb/A box if a field’s P, K, Mg, Ca and Na soil test levels are in Lb/A; leave the box unchecked if the test levels are in ppm. All five values must be in the same units. To convert a soil test level that’s expressed in ppm to Lb/A, multiply by 2. To convert a soil test level that’s expressed in Lb/A to ppm, divide by 2. • Why can’t I enter soil nitrate test data on the Soil Tests panel? Many states use a nitrate soil test in generating nitrogen recommendations. Nitrate soil test data is only valid for the year in which it was collected. This data isn’t relevant for multiple-year planning purposes. MMP can still generate N recommendations without the nitrate soil tests. • How do I override MMP’s default fertilizer recommendations? MMP’s fert recs are based on your state’s extension recommendations. If you have custom fert recs that you prefer to use instead, simply scroll the grid to the right on the Crops panel and enter your recs in the appropriate Custom colum
