It is intended for pre-emergence and post-emergence harrowing of field crops (cereal, fallow, technical crops) with the purpose of:
• surface loosening and soil aeration.
• destruction of filamentous weeds(//tractor-service.com)
The working organs of the hoe create an ideal background for the initial development of the root system of plants, they mulch the upper layer of the soil well, destroying the soil crust, thereby preserving moisture, and they destroy filamentous roots of weeds up to 100% at speeds of up to 20 km/h.
This makes it possible to switch to herbicide-free technology. When a monolithic soil crust appears on the early seedlings of cultivated plants, for example, corn at the stage of 2-3 leaves, when the use of tooth harrows is impossible, the efficiency of using a hoe increases sharply.
On corn crops with the use of a BMR hoe for treatment on seedlings (the "spike" stage) and in the 3-6 leaf phase, air access to the root system is ensured, 100% destruction of filamentous weeds, as well as up to 27.5% of weed sprouts, and preservation of moisture, which in turn has a favorable effect on the further development of cultivated plants. Up to 10-15% of cultivated plants are damaged when BZSS-1 harrows are used, and up to 0.8% of cultivated plants are damaged whenharrow hoe BMR is damaged.
On sunflower crops, treatment was carried out on seedlings (two false leaves) and in the 2-6 leaf phase, the effect was similar to the treatment on maize seedlings. Research data on the expediency of replacing nitrogen fertilizers with spring loosening with a BMR hoe have been confirmed.
