HARROWING OF CROPS WITH SIMULTANEOUS EXTRA FERTILIZATION
The combination of technological operations for harrowing fields of various agricultural crops simultaneously with fertilizing the plants with solid mineral fertilizers is proposed. Using the example of field experience in 2017, the effectiveness of various serial machines, such as: the rotational hoe MПН-5.6 with active and passive placement of teeth, the tooth-seed harrow ЗБП-0.6 and the “Klen-1.5” seed drill for simultaneous fertilization and soil loosening with double disc coulters has been tested. It is proved that the combination of technological operations in a single run of the machine-tractor unit across the field ensures decrease of the fleet of vehicles, its capital-intensity, energy and cash expenditure, as well as enhancement of the competitiveness of the produce obtained.
