A method of preparing a solid fertilizer, comprising:
- heating an organic material by subjecting the organic material to heat at about 100° C. to less than 400° C. for less than 30 minutes, wherein the heating provides a product substantially free of biochar carbon;
- mixing at least one of an inorganic or synthetic material comprising at least one of N, P, K, or S with the organic material to produce a mixture;
- and
- forming discrete particles of the mixture, wherein the organic material and the at least one inorganic or synthetic material are uniformly distributed throughout each of the particles.

- heating an organic material at a temperature and time sufficient to form a substantially sterile carbon product, wherein the heating at the temperature and time does not result in the formation of biochar;
- mixing at least one of an inorganic or synthetic material comprising at least one of N, P, K, or S with the substantially sterile carbon labile product to produce a homogenous mixture;
- and
- forming discrete particles of the homogenous mixture.
