Soil compaction consequences in the Hungarian and Croatian fields

In this paper occurrence, field and crop consequences and alleviation possibilities of the tillage-induced soil compaction are presented. Monitoring data taken in different soils, as well as the findings of a relevant long term experiments, as well as literature studies are evaluated in this study. The field survey comprised 2018 monitoring places on 17280 hectares and on 45 experimental plots. A total of seven typical versions of tillage-induced compaction were identified: 1) favourable to a depth of 60 cm ; 2) favourable to a depth of 40 cm ; 3) compaction at the depth of 28-32 cm ; 4) compaction at the depth of 22-26 cm ; 5) compaction at 18-22 cm ; two compact layers below 16 cm ; 7) three compact layers below 16 cm. Root zone state, occurrence of compacted layer in soil and extension of the compacted layer were chosen for monitoring. It is stated, that soil loosened to a depth of 35–40 cm qualifies as suitable, loosened to 28–32 cm is rated as adequate, while soil loosened only to a depth of 16–20 cm is conditionally adequate or inadequate. We want to stress that depth of the loosened layer is the same as the depth of the layer suitable for water intake. Presenting some examples of the crop responses to soil compaction hopefully help to avoid applying pan compacting tillage interventions. Reviewing methods may effective to avoid compaction threat and solutions are adequate to alleviate pan compaction may be induced a wider collaboration in concerned regional research.
