LIQUID ORGANIC PEAT FERTILIZER AND PROCESS OF PREPARING SAME

摘要

A novel process has been provided for the preparation of a peat fertilizer. The process includes the first step of subjecting particles of high-moor, low-decomposed sphagnum-type peat which has a lower proportion of humic acids, a higher concentration of hydrolyzable nitrogen compounds, and a higher proportion of weakly-bound biologically-active substances than low-moor peat, more than 50% of the particles having a diameter of 250 um or less, to a relatively mild acid hydrolyzation reaction at a maximum elevated temperature of 130.degree.C. carried out for a maximum period of time of 2 hours, in a metal-free container. The pH of the reaction medium is then adjusted to near neutral. Both the liquid medium and the solid residues are recovered. The liquid medium provides a peat extract which is substantially-free from biologically-undesirable concentrations of metal elements and compounds.
