Abstract
The commonly accepted definition of "sustainability" means the characteristic of a process or
state that can be maintained at some level indefinitely in time and space.
In the current conditions of progressive planetary degradation of climatic, en
vironmental, and
demographic conditions, agriculture has increasingly difficulty in reconciling the maximization of
crop results with the environmental sustainability, quality, and healthiness of products.
In the management of agricultural production factors, soil
quality has a leading role in terms of
choice and planning the implementation of the most modern technologies of 4.0 agriculture, in
precision farming systems.
However,
many agricultural soils have variabl e percentages of coarse fractions in the ir arable
layer, which interfere with cultivation needs, damaging machinery and requiring extra energy and
time for processing; to the point of making the use of machinery impractical.
In such conditions, it becomes ne
cessary to proceed with soil reclamation.
In this
thesis are presented: a review of the definitions, classifications and concepts of soil
quality parameters ; a description of the impact of skeletal constituents on soil workability, and the
reclamation techniques available for agricultural land; and the methods and results of an
experimental activity carried out in the Research Center of CREA IT in Treviglio, focused on the
validation of a deep burial method, alternative and more effective for the constitution of a fine earth
arable layer optimized for precision machinery (i.e. seeders), stable in the long term, and without
the negative effects of lowerin g the field plane, as in the case of removal, or modification of the
chemical physical characteristics of the soil, in the case of on site stone crushing.
