Abstract

The invention relates to a paper composition for biodegradable nutritive supports; it contains a nitrolignine and urea additive, introduced in a fibre mixture, made up of natural cellulose kraft, recycled secondary cellulosic fibre and peat, to which is added polyamide-polyamine- epichlorohydrin resin and aluminium sulphate. The use of this additive in proportion of 5-10% to the fibre material produces paper with higher resistance when dry, with high nitrogen content and high capacity of biological stimulation, shown by germination tests.
