Is this safe?

7 years ago

I added oats to this bag of cheap potting dirt to boost its life or to find if he had the right kind of mycorrhizal fungi. I thought that I could add a cheap N source since the bag reportedly had ~ 2% N by weight and 60% organic matter.

It was just backyard science, but guess what , I was given my first allotment, a 150m2 patch in sunny Portugal and now i really need to grasp the húmus science. The soil there is grey, is bad and weeds struggle. Is this the solution?
