Abstract:
Soil – a complex biodynamic system - and its thorough research
allow us to know and direct its most important properties in order to improve
both qualitatively and quantitatively the whole agricultural production and of
soil fertility, too. In order to ensure the best crop conditions necessary to the
cultivated plants it is compulsory to relate plant research with environmental
factors, as well.
This paper has as major objectives the delimitation, the inventory and
evaluation of soil resources, the delimitation and inventory of the limitative
or restrictive factors in land ise , as well as the production levels estimation
for agricultural lands expressed in terms of estimation records.
This paper presents several aspects concerning soil resources in the
Branistea Village area, located on the Covurlui Plain.
Appeared under various natural conditions, all the soils in the area
differ very much both in quality and fertility, in their production capacities as
well. That’s the reason why soil and land resource quality determination and
appreciation have a great importance. The Covurlui Plain, as an important
geographical area, presents a great variety and variability of environmental
factors which ultimately influence the conditions in which plants grow and
thrive. Therefore, an ecopedological research is compulsory if we want to
achieve a modern agriculture.
Plant production requires a perfect knowledge of their productive and
technological characteristics and of the unfavourable factors that inhibit
production.
All these studies concerning soil evaluation have emphasized a series
of limitative factors which negatively influence the production capacity of
these soils in the given area.
From 4,948 ha, some surfaces are degraded by various factors:
surface erosion, land slides, nutrient deficiency, secondary compactness,
deficient hydro-thermal sources.
All these limitative or restrictive elements that affect the productive
potential of soils may be altered through pedo-hydro-meliorative actions as
well as new measures for degraded soil conservation and protection.
We may conclude that knowing the factors that either improve or
diminish the production capacities of each area represents an efficient
