Physical soil amelioration:
Remediation of soil compaction: The TLG 370 soil loosener allows the loosening of soil layers up to 80 cm depth
The use of heavy construction machinery or the improper treatment of soils often results in soil compaction. This leads, on the one hand, to a pore volume too low for plant growth and on the other hand to too little oxygen content in the soil. Clayey and silty soils with low structure stability are especially vulnerable to damages by compaction, particularly to exposures in connection with unfavorable soil water content.
The first step to recultivate compressed soils is physical soil amelioration, which primarily aims at improving air and water balance of the soil. Physical soil amelioration includes all soil break-up measurements (aeration). Our equipment (e. g. depth loosener "Spatenpflug MM 100") enables us even to perform depth soil loosening down to 80 cm. In this field, BENDER has played an active role for many years.
Soil aeration is not restricted to the elimination of damages caused by construction activities (e. g. pipeline construction). It can be applied equally successfully within forestal and agricultural recultivation measures and land consolidation. The such achieved optimization of the soil air and water household results in an impressing amelioration as vegetation site.
Soil improvement influencing the substantial properties of soils are summarized under the term chemical soil amelioration. Those are primarily measures for increasing or decreasing the soil pH, for optimizing the nutrition contents and reducing or eliminating harmful substantial influences like salinization or contaminations. These interventions improve the substantial prerequisites in soils extremely acid, extremely alkaline, poor in nutrients or contaminated, such that sound plant growth is possible with reclamation and erosion control measures.
Chemical amelioration measures are dominantly required in mining areas (liming of acid soils), on raw soils lacking humus (fertilization), in salinated sites (reduction of ion activity) and the decontamination of contaminated, hazardous sites.
