Factors studied

Positive effects

Negative effects

- Save time by avoiding subsequent weeding.

- Time to let the weeds rise and destruction time: plan a longer period between 2 crops.

- Fewer herbicide purchases.

- Fight against pests and diseases (destruction of fungi, eggs and larvae) by the action of the sun's rays, and/or by exposure to predation.

- The only effective means of combating certain perennials.

- Risk of soil compaction if the mechanical work is poorly managed.

- Risk of erosion with superficial tillage in the tropics.

- Fewer weeds in harvested products.

- Less pesticide residues.

- Preservation of water quality thanks to less use of herbicides.

- Energy consumption can be compensated by the reduction of passages of herbicides with the towed sprayer.

- Increased fuel consumption.

- Gas consumption if thermal weeding.
