  No-Tillage (NT) and Minimum Tillage (MT) have, in recent years, become tillage systems for soil conservation, popular in Romania. Their insertion in agricultural practice reduces soil degradation phenomena, avoids the implementation of an intensive management and reduces production costs. This work had as objectives: to assess the effects of tillage systems on compaction, temperature and soil moisture, as well as establishing the effect of the changes on the production of wheat, maize and soybeans. The study was conducted on an argic-stagnic Faeoziom. MT and NT application reduce or completely eliminate the soil mobilization, due to this, soil is compacted in the first years of application. The degree of compaction is directly related to soil type and its state of degradation. The state of soil compaction diminishes over time, tending toward a specific type of soil density. Soil moisture was higher in NT and MT at the time of sowing and in the early stages of vegetation, then the differences diminishes over time. Moisture determinations show significant differences, statistically insured. MT and NT systems reduce the thermal amplitude in the first 15 cm of soil and increase soil temperature by 0.5-2.2°C.Water dynamics and soil temperature showed no differences that could affect crop yields. Productions obtained at MT and NT don’t have significant differences at wheat and are higher at soybean. The differences in crop yields are recorded at maize and can be a direct consequence of loosening, mineralization and intensive mobilization of soil fertility.

  The different content of heavy metals measured in the soil and in the plant in the historically polluted area of Zlatna, in the years 2009 and 2010, confirms the influence of various factors, among which the way the tillable soil is tilled.
