The effect of biochar on plant diseases: what should we learn while designing biochar substrates?
The increasing demand for soilless substrates and rising environmental concerns about the use of non-renewable resources such as peat has led to the search for alternative constituents of growing mixtures for containerized plants. In this report we reviewed the works concerning biochar as constitue...
