Abstract:
The study, carried shows the suitability of some soils for different use
categories and crops in the District of Mehedinţi.
Knowing in detail yielding and technological features, favouring and
restricting factors of agricultural production on each land portion both from
the point of view of present response and of real possibilities of turning them
into better ones can be, for the decision-maker a precious tool in achieving
the most suited practical measures of producing plant biomass in a dynamics
well correlated with environmental ecological requirements.
This is why, in this paper, after presenting in detail the physical and
geographical conditions (relief, lithology, hydrology, climate, vegetation,
anthropic influences) we have acknowledged the above-mentioned
components allowing to explain both phenomena in the soil and the way they
can be influenced by man, that could become a wise partner of the nature.
To make the assessment calculus we have chosen from the multitude
of environmental conditions that characterise each land unit within the
District of Mehedinţi only those considered most important, easier and more
accurate to measure, that can usually be found in soil study works, called
assessment indices.
Increasing yields and agricultural lands fertility are directly
determined by detailed knowledge of soil solidification process, evolution
and supply with main nutrients.
The present work wants to establish the best soils for cultures and
plantations which have been taken in consideration.
Previous researches concern numerous analytic data for a period of
over 40 years an interval in which numerous changes have occurred both in
soil features ad in research methodology, mapping and improvement.
