Abstract
Soil compaction supposes the soil volume compression under the action of external factors. As the solid particles cannot be compressed, the porous spaces between them are reducing and therefore through compaction the dimensions of pores, their distribution as well as the soil's durability are modified. The degree of soil compaction can be estimated by using its bulk density, total porosity and settling compaction degree. The aim of this study was to identify the best soil tilling equipment to be used in forest nurseries in terms of reducing the soil compaction and increasing the operations quality, by introducing that kind of equipment that has the capability to minimize the soil compaction. A study has been carried out in three forest nurseries located in the area managed by the Forest Administration of Arad, during 2010-2014, on different soil types. Some of the physical and mechanical properties following the classical (plow, disc harrow) and minimum tillage (scarifier and harrow) options were taken into study. The soil compaction in the forest nurseries was characterized by the increment of bulk density and the reduction of total porosity, hydraulic conductivity and the air permeability. These modifications influenced the air and water mobility in the soil. Mechanical tilling may either trigger or avoid the soil compaction. Excessive soil tilling may favor the degradation of soil structure with immediate effects on the surface compaction. Repeated plowing and harrowing of some soils at the same depth may trigger the formation of compacted layers beneath the working depth. In general, the ability of soils to resist compaction was reduced as their moisture increased. When the soil was too wet, its plasticity and adherence were increased, generally leading to the deterioration of structural aggregates, resulting in compaction.
