fertilization in the soil. The purpose of the invention is to increase the efficiency of fertilizer use, the retention of melt water and reduce soil erosion. Manure in the form of a solid fraction is placed in the winter period on the surface of the frozen soil with the formation of rolls in mutually perpendicular directions. After laying the manure roll, it is covered with snow. In winter, the swaths contribute to the retention of snow, and during the thawing period - melt water. After the snow has melted, manure rolls are worked on the surface of the field and plowed.

The invention relates to agriculture, namely to the technology of fertilizer in the soil.

The aim of the invention is to increase the efficiency of fertilizer use, retention of melt water and reduce soil erosion.

Example. With the help of tractor units (snow plows, graders) and other means open snow cover, forming a bed on which the converted manure rolls with subsequent closure with snow are converted by converted body manure spreaders, trailers, dump trucks and other means. Operations can be performed by one unit with the necessary technical means or several units in series. The passage of the aggregates across the original rollers arranged in the same way are followed by subsequent manure rolls. As a result of mutually perpendicular passages of the aggregates between the rollers, small areas in the form of micro-limans are formed. In winter, the swaths and micro-limans contribute to the retention of snow, and during the period of thawing - to the retention of melt water. After the snow melts, the manure rolls are scattered or spread over the surface of the field, followed by mixing with the soil and embedding it in the soil with tillage tools.

For example. The unit, consisting of a tractor with a bulldozer in front or corner snow-plow, and behind the body-mounted trailer spreader, re-equipped to form a manure roll, moves along the snow field in one direction. As a result, the snow cover with a bulldozer (snow plow) is moved apart and a bed is formed on which the manure roll is laid.

At the same time or with some time lag behind the first unit, the second one is turned on, consisting of a tractor and a snow trap of the swather.

When it moves, the manure roll closes with snow. After the passage, the unit turns around at the end of the rut and moves in the opposite direction. The distance between the passes of the unit is determined by the width of spreading or pulling the manure out of the roll by the implements. Similarly, rolls of manure and snow are laid in the perpendicular direction to the first pass. Work units can be performed simultaneously in mutually perpendicular directions.

snow and drying of the soil the spreading of manure from the rolls across the field is carried out using, for example, a rotary type spreader.

In this case, the units can work in two mutually perpendicular directions, which ensures a more uniform distribution of manure across the field and high rates of work. After this, the field is cultivated by tillage implements 1 (plowshare or disc stubblers), the manure is mixed with the soil and plowed down.

it thaws faster and in the spring period more intensively absorbs and retains thawed snow than it reduces soil erosion; manure is most evenly distributed and embedded in the soil.

Claims (1)

Claim The method of fertilizing the soil with manure, including its distribution in winter on the surface of frozen soil in rows and covering with snow, characterized in that, in order to increase the efficiency of fertilizer use, retain melt water and reduce soil erosion, manure is used as a solid fraction, and its distribution on the surface of the frozen soil is produced with the formation of rolls in mutually perpendicular directions.
