1864d Mould

Matthew, P. Baron Liebig versus the vegetable mould. Gardeners’ Chronicle and Agricultural Gazette (23 Jan 1864), p.83

(Letter not dated, article printed Jan 23)
Matthew quotes from Liebig’s letter to him, from a paragraph that was not printed in the original Editorial (1864a). This again indicates that Liebig seems to attach great importance to his royal approval. Matthew criticises Liebig’s views regarding the soil vs the atmosphere as sources of nutrients for plants.
