Dear Dr. Young Sang Cho, first of all, congratulations on your PhD!

I am an apple farmer.

My question is this: I practice organic farming in and I have started using your JADAM method and getting good results. However, the problem is that my soil is deficient in NPK. My soil test report shows very low levels of nitrogen, potassium, and boron. How can I address this deficiency?

Do you have any specific recommendations or a package of practices for apple cultivation?
