Summary.
The basis of the technical and technological methods of solving the problem
of reducing soil compaction in order to maintain the fertility of the land is as follows:
harmonization of technological operations during one
passage of the aggregate
across the field, simultaneous tillage and planting, fertilizing in the system and the
use of multifunctional aggregates such as tillage and soil compaction. simultaneous
pinching of
grain crops, simultaneous harvesting of husks or pressing of straw, etc.,
rejection of the use of additional heavy machinery, trucks and tractors with a narrow
chassis in the fields.
Taking into account the set of parameters of the portable power structure and
the condition of the soil, equations were proposed that determine the
pressure force
at the bottom of the portable power structure.
For driving a large and heavy tractor, it is recommended to choose a small-
sized tractor for horticulture, as well as a portable power tool depending on the type
of soil cultivation.
The use of seats with rubber-reinforced tracks leads to the saving of resources
and an environmentally favorable impact on the soil.
Soil moisture maintained by watering, it is better to ensure optimal moisture.
creating conditions for good growth and development of plants and increasing their
productivity,
but at the same time, the use of machinery
with a large mass and
making too many passes through the field led to excessive consolidation of the soil.
Is significantly reduced
compared to uncompacted soil, and the filtering
capacity of the topsoil can greatly impede the flow of irrigation water into the soil.
When using wide-profile low-pressure tires on tractors, productivity increases
by 45%, costs decrease by 35%. By increasing the width and length of the tire patch,
the costs will not be large and the performance will increase significantly.
