Cultural measures

Rotation

Description:

Crop rotation is based on the alternation of different crops with distinct nutritive needs, to improve soil fertility and to avoid or reduce the incidence of pests and diseases and to help control weeds.

Regarding pests and diseases, crop rotation breaks their life cycle, setting them in a habitat in which they cannot develop.  

Regarding weeds, the rotation of crops allows increasing the number of phytosanitaries that can be used in a plot, so the possibility of creating resistances is lower and the control of species, which are very difficult to control under monoculture situations, is much better.

Besides, the insertion of fallow land in the rotation allows having a fraction of the soil without any crop. The germination of weeds is favoured in this fraction and then, they can be eliminated before the establishment of the next crop.

Implementation of this measure in LIFE AGROintegra project:

This cultural measure has been applied in some of the demonstrations carried out in arable crops. For example, one of the experiences has analysed the effect of the previous crop (sunflower) in the incidence of pests and diseases of wheat.  

Furthermore, crop rotation has been also applied in the strategy of transformation of the farms of Sartaguda and Ilundain, through spatial and temporal alternation of crops. In Ilundain, the surface of alternative crops has increased to 26% in the last year of the project.

Tillage

Description:

The tillage is a tool that allows controlling the germination of weeds during the period in which the plot does not have any crop.

Deep tillage with mouldboard before the sowing period reduces the feasibility of species that have more superficial germination such as annual rye-grass (Lolium rigidum) or great brome (Bromus diandrus).

Besides, it is possible to make a shallower tillage during the summer, to stimulate the germination of weeds’ seeds that are in the soil and to eliminate them before the previous campaign. This technique requires adequate climatic conditions (humidity) that favour the germination.

Implementation of this measure in LIFE AGROintegra project:

This measure has been included in a real-scale demonstration in arable crops in order to evaluate the effect of deep tillage on reducing the amount of weeds. This technique has also been applied in the farm of Ilundain to reduce the viability of superficial germination species such as black twitch (Alopecurus myosuroides) and matgrass fescue (Vulpia unilateralis).

Furthermore, one of the trials has analysed the effect of shallow tillage after the campaign to favour the germination of weeds in the summer, so they can be eliminated during the preparation of the soil in the next campaign.

Sowing date

Description:

The delay of the sowing date is another interesting tool to control pests, diseases and weeds. For example, in the case of BYDV (Barley Yellow Dwarf Virus), it is more common to observe virus in early sowings, because the germination coincides with the moment in which the presence of aphids is higher.

Regarding weeds, the delay in sowing date, in combination with false sowing, favours the germination of autumn-germinating species. Then they can be eliminated during the preparation of the soil for the next crop.

Implementation of this measure in LIFE AGROintegra project:

The efficacy of this technique is also being evaluated in the demonstrations of integrated pest protection carried out in the project with arable crops.

Regarding pests and diseases, various experiences analysed the effect of the delay of the sowing date in the density of weeds in cereal crops (wheat and barley). The figure 1 shows a photo of one of the plots in which this technique was applied.
