(54) METHOD OF STRUGGLE AGAINST AQUATIC EROSION OF SOIL

t

The invention relates to agriculture and can be used to combat water soil erosion and increase the productivity of agricultural crops.

There is a method of anti-erosion treatment of meadows and pastures located on the slopes, including cutting gaps and mineral fertilizers in the parastetal space on both sides of the gap in the upper soil layer to a depth of 6-8 cm, width of up to 0.5 m p

However, this method is unsuitable for anti-erosion treatment of crops of perennial grasses and winter crops due to an unacceptably large percentage of damage to plants by working bodies for subterranean fertilization and gaps since each passage of these organs disrupts soil cover over a large area, while cutting the roots of plants a depth of 6-8 cm, a strip of up to 0.5 m

There is also a known method for combating water erosion of the soil, which consists in the fact that initially the soil was completely loosened with the help of lancet paws, including with the goal of killing weeds. Then, the soil is cut (slit) with combined knives-slits into the depth of up to 45 cm. During the cutting, the soil is moved apart by a thickened part of the knives and compacts it, forming a narrow channel into which

15 mineral fertilizers. Behind this, the channel is crammed, its walls being sealed with spherical disks-rollers. The prizes are wedged out and other irregularities are leveled with the help of 20 gortachs, while the channels are formed (slots J are covered with loose fluffy. The method provides for the absorption of water flows, especially in areas where 3 rain is predominant, reducing erosion of f2). However the application of the known method on winter and perennial grass crops leads to significant damage to plants when cutting the slit by the broadened part of the combined knife-gaping and re-broadening the slit (channel) with spherical discs with rollers. The canals formed by a known method, during the spring runoff of melt water, swim relatively quickly, silted up with the sodden soil, which was previously filled up with slots (channels). As a result, the water regulating role of the cracks decreases, especially at the time of maximum runoff of melt water. invention - increasing the productivity of agricultural crops by increasing the water regulating capacity of the gaps. The goal is achieved by the fact that at the time of cutting gaps in its walls on both sides at a depth of the wands of the seeds form horizontal grooves to which you make

Sowing seeds, after which the walls of the slit and the soil sprinkling into the slit are irrigated with a solution of nutrients, and the main crop is sown on an area not occupied by the slits.

The drawing shows an example of the implementation of the proposed method.

The method is carried out as follows.

Across the slope at the same time as sowing, for example winter crops, slits 1 are cut, and in their walls at the depth of embedding seeds form horizontal notches 2 and 3, on which seeds 4 and 5 of the main crop are sown under the cover, after which the walls of slits and crumbling loose soil fall into the slit Irrigate with a solution of nutrients and, on an area not occupied by a crevice, they sow the main crop 6.

The anti-erosion efficiency of the slit is increased by increasing the water-regulating role of the gaps by filling the slotted space with the root system of the cultivated crop by sowing seeds in the walls of the slit into horizontal grooves with irrigation of the walls of the slit and filling it

As a result, nutrient substances are enriched in the walls of the slit and loose soil environment, filling immediately after the passage of the slit-gap, the slit space throughout the depth of the slit, while sowing seeds into the walls of the slit provides intensive root formation in the zone of increased nutrient concentration, and this a controlled process of root system development in the volume of the gap space is carried out. Moreover, the anti-erosion efficiency of the gaps in the initial period in the absence of vegetation cover, for example, after sowing winter crops with gaps, provides good permeability of loose soil that fills the gap space. i Subsequently, in the period of developing vegetation, the anti-efficacy is provided due to the high water permeability of the gaps as a result of intensive root formation of plants in the slit space, and the vegetative part above the gaps actively opposing their swimming and silting. b moment in-by / nenya g- After ipolmeniaA five
