FIELD: agriculture. ^ SUBSTANCE: organo-mineral complex fertilizer contains bulk and liquid components such as disinfected, neutralized and dried silt produced by biological purification of sewage water, and carbonic acid H2CO3. Method involves forming furrow simultaneously with soil plowing; distributing liquid component and closing furrow; simultaneously with liquid component, introducing bulk component, each component being located at different depths by means of deep tiller which is used for forming of furrow bottom with depressions; feeding carbonic acid under pressure into depressions, with following closing of furrow; plowing-in bulk component by turning top layer of mold by means of moldboard fixed to deep tiller. ^ EFFECT: increased efficiency in humus formation, increased soil fertility and yield, and improved ecology of farm crop cultivation. ^ 7 cl, 3 dwg |
