Fuente: WIPO "biotechnology" The invention relates to a soil amendment composition capable of stimulating the reproduction and development of normal soil microflora which produce ammonia and enzymes that are antagonistic to plant pathogenic nematodes of selected crop plants, which comprises: (a) at least one of (a)(1) vegetable, fruit or nut meals, and (a)(2) chitin-protein complex, and (b) a source of urea, the component (b) being present in an amount effective to provide ammoniacal nitrogen sufficient for suppressing the growth of the pathogenic nematodes and the component (a) being present in an amount effective for suppressing the growth of the pathogenic nematodes in combination with component (b) while alleviating phytotoxic effects of component (b), whereby the amounts of (a) and (b) in the composition being adapted to provide 1 to 3 grams of the composition per kilogram of soil in which the composition is admixed. Methods for applying the above composition so as to suppress the growth of the plant-pathogenic nematodes are also disclosed...
