In our opinion, the problem of periods with extreme precipitation could be remedied at a
cost which is lower by magnitudes than the losses sustained. One thing is certain: the principle
of „Think globally, act locally” is applicable here as well. In this case, „local” refers to
countering detrimental effects on or below plot level.
Experience so far indicates that areas with high water table need to be addressed as a separate
category with respect to the selection of species, varieties and hybrids as well as in terms
of production technology and agrotechnology, allowing for the fact that environmental effects
are decisive for both aspects.
At the same time, modern geospatial information systems are now essential in recording
data about both crops and soil and in carrying out the necessary monitoring tasks. On the
other hand, it remains necessary to adopt and improve methodologies for the online recording
of physical and chemical characteristics of soil. The resulting databases could in the future
contribute to replacing physical detection methods with satellite-based (hyperspectral) ones.
Additionally, we are convinced that the procedures and modelling methodology presented
in the paper can significantly contribute to designing a comprehensive national research
project which would provide local, plot-level answers to yet unresolved practical issues.
ENVIRONMENTAL SOIL TILLAGE (3E) AND MACHINERY
– A RESPONSE TO CLIMATE CHANGE

JÓRI J., ISTVÁN
Keywords: sustainability, climate change, soil tillage, machinery.
One of the essential components of sustainable development is the rational use and protection
of our most important natural resource, the soil, as well as the preservation of its versatile
functions. This is one of the most important tasks common to environmental protection and
agriculture. Soil and the environment mutually affect each other. For one, soil „suffers” the often
detrimental stress occurring in the environment, but it may also be the cause of such stress
– primarily if used incorrectly – and give rise to threats to other components of the environment,
such as the underground and aboveground waters, the atmosphere near the ground, the flora
and fauna, as well as the landscape. The solution lies in the environmental soil tillage system.
