Weed control in organic pome fruit growing: Combining different approaches (BIOFRUITNET Practice Abstract)

Summary in the original language of the document

The disadvantages of relying on one machine can be partially compensated by combining different approaches and tools. This optimised tillage makes it possible to adapt to different conditions (e.g., weather, soil conditions, etc.).
Practical recommendations
• A widespread strategy is the combination of a gyroscopic crumbler and a thread mower:
o In spring, turn under organic material into the soil with the gyroscopic crumbler.
o Beginning in the summer, when tree growth calms down (from July), the thread mower can be used to avoid increased nitrogen mobilisation from soil disturbance, as only surface mowing occurs with the thread mower.
o Towards winter, it is recommended to treat again with the gyroscopic crumbler. This method also helps to manage mice by providing them with little coverage.
o The possible choices between these two types of equipment allow optimal weed management considering nutrient availability, soil conditions and the local weather situation.
• Another strategy can be the combination of a roll and finger hoe or a disc plow in Spring, with a thread mower in Summer:
o The roller and finger hoe are used in spring and after harvest to break up the soil and incorporate weeds.
o The thread mower is used in addition, in the summer months, to suppress weeds, grasses and root shoots (see above).
