Spatial modelling of the influence of farm management practice on the infiltration potential of agricultural soils (HOT)
Project
Project code: JKI-PB-08-0022
Contract period: 01.01.2008
- 31.12.2019
Purpose of research: Applied research
Investigations in organic managed farms showed that the number of earthworms (as well as the quantity of bio pores) is about 7 times higher and the infiltration rates of the soils are about twice as highly as in comparable conventional farms. The increase of the infiltration rates by a change in management practice (e.g. preserving cultivation, extended crop rotations, optimised humus balances, supporting liming) offers a large potential to hold the quantity of superficially flowing off rainwater temporally back. At the same time improvement of the infiltration capacity leads to a reduction of the evaporation, that water remains longer stored and the ground-water formation rate is increased.
