Soil Test Results

10 years ago
last modified: 10 years ago

Can someone help me interpret these results? The following is MSU's recommendation:

(1:1 or ~1:1.5 N:P2O5 ratios)

  1. Sample analysis: 18-24-12, 24-24-4
  2. For example, two applications of 18-24-12 would deliver 2.6 lbs. P2O5which would meet the P recommendations for the lowest soil test P level (1 ppm) but would only deliver 1.4 lbs. K2O. For K soil tests less than 80 ppm additional K applications would be required.
  3. Advantage: The main advantage of using starter fertilizer products is that they are generally not 100% fast release nitrogen sources and they will meet the P recommendation with fewer applications than other fertilizers.
  4. Disadvantage: products with these analyses require multiple applications over several years to meet K recommendations.
  5. Alternative is to use starter fertilizers to meet P recommendations and then use potash (KCl) to meet K recommendations.

Are they just telling me to do two applications of starter and get another soil sample?
