Remedying water-logged soils by means of adaptable tillage

The extreme climate phenomena that wreaked havoc in the Pannonian region in 2010 had very negative impacts on soils as well and this study contains an assessment of some of the consequences of the stress caused by precipitation on soils. The relatively rapid regeneration of chernozem soils damaged by hail was encouraged by consistent organic matter conserving tillage. Soil settlement along with the damage of the soil structure in the top 50 mm layer was monitored in a long term experiment, applying six different types of tillage techniques, in an environment characterised by 651 mm annual precipitation, from the time of the sowing of maize in the layer loosened by tillage. The best chances of minimised damage were observed in the case of the production of wide-row crops where the soil contained no compact layer and where about 30 % of the soil surface was covered. Loosening in the case of tillage carried out in the summer on moist soil occurred only where less heavy damage had been caused, under a minimum of a 40-45 % soil surface cover. The value of the relevant studies was increased by the enabling of the recovery of damaged soils and our recommendations were summed up in 18 points.
