Quick test for infiltration of arable soils
Problem
Driving on arable land with heavy machinery while the soil is too moist leads to soil compaction, which severely impairs airflow and drainage. Especially crops in heavy soils react to this situation with yield losses.
Solution
With the aid of a simple quick test, water infiltration – as one of the characteristics of soil compaction in the field –can be clearly examined. The quick test is also easy to understand and helpful for non-scientists. It is particularly suitable for training farm apprentices and employees, and raising their awareness on the issue.
Advantages
The quick test uncovers the consequences of soil compaction on water infiltration and the yield of arable crops. It promotes an understanding of the effects of soil compaction and the importance of soil conservation.
Practical recommendation
For training purposes, a direct comparison of several quick tests should be carried out at different areas on the same field. The comparison of tests taken in the tramlines, on the headland and in the non-trafficked area might be particularly interesting. In addition, one might also select areas where the crop grows particularly well or poorly in order to check whether the growth of the crop is related to soil compaction.
The moisture status of the soil prior to the test time has a major influence on the ability of the soil to absorb more water. This limits the comparability of the results to a single point in time. To increase comparability, the soil can be thoroughly watered 12-48 hours in advance.
