Abstract:

The use of landed resources within agricultural ecosystems presupposes a thorough knowledge of the ways of manifestation and evolution of all restrictive factors.

As a consequence, we must perform pedological studies periodically which offer a primary database of morphological and physico-chemical characteristics on soil-mapping units (SU) and homogeneous ecological territory (HET). Through detailed soil surveys and soil evaluation we achieve a set of graphical and descriptive database which are necessary for the assessment, classification and evaluation of the soil resources of a given geographical area.

The soil cover is being studied in accordance with natural and anthropic factors which determine its natural qualities and fertility, with soil suitability for developing natural and cultivated phytocenoses.

Soil production capacity for various agricultural utilizations depends on general restrictive factors, such as: frequent drought, water-logging, erosion, landslides, etc. All these factors determine soil quality degradation leading to the decrease in agricultural land production capacity. From an I.C.P.A. assessment carried out together with regional offices for pedological and agrochemical studies and other research units upon 12 million ha of agricultural lands ( out of which about 7.5 million ha arable land), soil quality is affected by one or more restrictions. They are determined by either natural factors or human activity.

Legislative measures have been taken with a view to improving soil degradation in our country and abroad.

So, Law No. 137 /1995, concerning environmental protection, stipulates that the central authority for environmental protection and by consulting other ministries, has established a monitoring system for soil quality in order to know its actual state and evolution.

According to Decree No. 62 / August 21, 1998, a legal frame has been set up for improving about 2.5 million ha of degraded lands.
