<p>The invention relates to a process for preparing a biofumigant for the soil, applicable in agriculture. According to the invention, the process consists in mixing 1.2...1.25 parts of plant stalks used in the production of industrial oils with 1 part of grit resulting from mechanical extraction of oil, followed by grinding and discharging the mixture through a sieve having the mesh diameter sizeφof 6...8 mm, the mixture being then passed into a lined mixer and moistened with a 0.2 M trehalose solution made of 5 parts of solution per 100 parts of mixture, the parts being expressed by weight, followed by slow mixing for 2.5...3 h, for mixture maturation, at a blade speed sigma of 2...3 rpm, the mixture being finally compacted into pellets having a diameter of 2...8 mm, a length of five times the diameter and a density ranging from 90 to 1100 kg/m.</p> |
