I am not sure if you can help me because this is in a greenhouse, but I am sure you have some knowledge, as it is just soil. I had a soil test done on my soil in my greenhouse and my Nitrate-nitrogen level are very high 72.0 ppm. How can I lower this? The pH was high 7.4, organic material high 11.8, potassium high 183.9 ppm. he soil is sandy, clay loam in texture. What can I do to correct this? If you can't help me, any suggestion of who might be able to? Thank you for your time and thoughts.
