Soil help in NNJ

Post by Lawnguy_nnj21 »

Happy Thanksgiving all!

Below are results from my last soil test (yes they are from MySoil.....I get it but this is what I have right now). While I have my thoughts about what I should do next year (and their recommendations), I am curious to hear from more informed individuals. Basically ph, and NPK are all low. I plan on being more committed to getting the soil better at this point but not sure on the best direction. Should I use a balanced fertilizer all year next year?

Any help would be appreciated.

Front yard
pH 5.47 5.8-7 Low
Total Nitrogen (N) 4.71 7-18 Low
Nitrate (NO3-N) 0.61 - -
Ammonium (NH4-N) 4.1 - -
Phosphorus (P) 2.86 5-11 Low
Potassium (K) 24.29 38-72 Low
Sulfur (S) 2.47 7-16 Low
Calcium (Ca) 122.82 93-314 Optimal

Based on these test results, I would start by applying dolomitic limestone now as long as the ground isn't frozen. This will bring up your pH and Mg without spiking your Ca too high.

Apply a balanced N-P-K fertilizer early next spring.

In the future, I would use the Rutgers cooperative extension for soil tests in your area.
Tier 1 - I just want something green. Perennial "weeds" that stay green year round are welcome.
