Calculate the risk of wireworm infestation in the field Organic Eprints
Dierauer, Hansueli; Weidmann, Gilles; Siegrist, Franziska.
• In spring, with a soil temperature of at least 8 °C, place a pot full of cereal or maize grains into water and allow it soak for 24 hours. • Spread out the soaked grains on about 20 cardboard or plastic plates, pot traps, stockings with adequate mesh size or similar materials. Sealable containers must have several holes; through which the worms can access the trap. • Position the traps at a depth of 10 cm with at least 10 to 15 traps per field. The more traps per ha, the more reliable the results. Cover the traps with earth to soil-level and mark the locations. • After 7 to 10 days, dig out the traps, collect them and count the wireworms. • If one or more wireworms per trap is found, the field is infested quite strongly: economic losses are to be...

IFOAM Training Manual: Training Manual for Organic Agriculture in the Humid Tropics Organic Eprints
Kilcher, Lukas; Weidmann, Gilles; Garibay, Salvador V..
The first IFOAM Training Manual for Organic Agriculture in the Tropics (the Basic Manual) was published in 2004. The Research Institute of Organic Agriculture (FiBL) together with partners of the organic movement in the Tropics were commissioned by IFOAM to complete two new training manuals that build on the Basic Manual. The new IFOAM training manuals address the two basic climatic zones of the Tropics, the Arid and Semi-Arid Tropics, and the Humid Tropics. For both new manuals, already existing material was collected, screened and condensed into comprehensive training manuals. Additionally, a large number of farmers, trainers and scientists were asked for their experience. Partner institutions from the Tropics actively collaborated in the development...

No-till cultivation of maize in rolled forage peas Organic Eprints
Dierauer, Hansueli; Siegrist, Franziska; Weidmann, Gilles.
The non-tilled, constantly covered soil has improved water retention and also shows a better carrying capacity during harvest, and is less affected by weed infestation, compaction, nutrient-leaching, and erosion. Stockless farms especially benefit from the nitrogen input of the legume-green manure. • At the beginning of August, carry out 1 to 2 stubble-tillage operations after cereal or rape harvest. • Sow the wintering forage peas in October. • At the end of May, kink the peas' stems with a knife-cylinder roller, after which you drill in the maize with row cleaners. The green manure lying on the ground must be properly dried off for sowing. • The mineralisation performance, lowered due to the soil cover, can be compensated for with focused nitrogen...

Use of rock dust against the rape pollen beetle Organic Eprints
Daniel, Claudia; Conder, Malgorzata; Weidmann, Gilles.
Through the use of rock dust at the beginning of the bud development, the infestation by the rapeseed beetle can be reduced by an average of one third. In the treated area the pods per square meter increased by up to a quarter, thereby increasing the yield in treated areas by around 25 %. Practical recommendation • Optimal time of treatment: The rape pollen beetles enter the fields at a temperature of 15 °C. Therefore a first treatment with rock dust is appropriate as soon as this threshold has been reached and the buds become visible between the leaves and will be reached by the spray liquid (BBCH 52). • Note: Pollen beetle infestation is supported by late blooming, frequent rapeseed cultivation and cultivation close to woodland. • A second treatment...

Practice Abstract: Intercropping grain peas with barley Organic Eprints
Klaiss, Matthias; Siegrist, Franziska; Weidmann, Gilles.
Barley prevents pea lodging, thus reducing the losses during threshing, and increases the quality of the harvested crop. The cereal crop also improves the soil cover, suppressing weeds. Growing two crops at the same time reduces the risk of yield loss. • The seed bed should be not too fine-grained after cultivation or reduced tillage (advantage: better channel flow from deeper soil layers during drought periods). A further possibility is mulch-till, whilst on heavy soils a plough with subsoiler might be needed. Possibly application of green manure or compost. • For seeders with only a single tank, mix the seeds well at the ratio of 80 % peas and 40 % barley (relating to the standard sowing quantities of both crops) before filling the seeder. Until...

Control of creeping thistle by stubble cultivation Organic Eprints
Dierauer, Hansueli; Siegrist, Franziska; Weidmann, Gilles.
Multiple cultivations lead to a repeated physical damage of the thistle. Each time it regrows, it uses further nutrients until it is weakened and a new crop will out-compete it. This method is also effective against other root-spreading weeds such as couch grass and bindweeds. • After harvesting grains, perform stubble cultivation with a skim plough or a completely flat-cutting wing share cultivator at a depth of 7-10 cm. • After the thistle plants have re-emerged (maximum 10 cm), repeat the cultivation 1-2 times while increasing the working depth. • Sow a dense, fast-growing catch crop such as vetch or fodder radish after the stubble cultivation to further weaken the thistles. This method only works on dry soils and in dry weather; in wet...

Black-grass control in winter cereals with hoeing Organic Eprints
Dierauer, Hansueli; Siegrist, Franziska; Weidmann, Gilles.
Thanks to the use of the bladed hoe, strong-rooting grass weeds can be successfully uprooted even in heavier soils. Other problem weeds, such as cow vetch, hemp-nettle, windgrass, or burdock, can also be controlled with the bladed hoe. • Sow the winter cereal in October, in rows with spacing of at least 20 cm. • When the cereal is at the 3-leaf-stage, control sprouting weeds with 1-2 harrowing procedures. • After using the harrow and as the winter cereals begin tillering, root out the yet intact, well-rooted grass weed between the rows with help of a duckfoot-bladed hoeing device. The duckfoot bladed hoe may also be used in combination with the harrow.

Nitrogen supply for winter oilseed rape Organic Eprints
Daniel, Claudia; Dierauer, Hansueli; Clerc, Maurice; Conder, Malgorzarta; Weidmann, Gilles.
Optimal fertilisation ensures that the current rapeseed varieties and reach their full yield potential. Practical recommendation • In conventional cultivation, the nitrogen uptake of winter oilseed rape amounts to 140 kg N per ha for a yield expectation of 35 dt per ha. In organic agriculture, about 100 kg suffice for a yield expectation of 20-25 dt. • The ideal time for cultivating oilseed rape is after grass-clover or legumes. After grains, apply about 30 tonnes per ha of manure or manure compost before cultivating rapeseed. • In dry conditions in spring, an early single application of nitrogen is preferable to two smaller applications. In the case of slurry with a low N content, two applications are often required because maximum of 40 m3 of slurry...

Rolling of grains to prevent winter kill damage Organic Eprints
Dierauer, Hansueli; Siegrist, Franziska; Weidmann, Gilles.
The pressure of the roller stimulates not only the forma¬tion of roots and improves access to water, but stimulates also the tiller of the grain increasing its stability and thus reducing the risk of falling over. Practical recommendation • Rolling requires dry soil in order to prevent the soil from sticking to the roller and ripping out the plants (especially when using smooth rollers). • The corrugated roller must not damage the plants too much. Take special care when using sharp-edged rollers. • Every mechanical interference puts the plants under stress. For this reason, it is advised to go at a maximum rolling speed of 5 km/h. Notes • Even in densely sown or strongly fertilized spelt crops, the rolling is recommended. It weakens the main shoot...

Reducing the use of copper in potatoes Organic Eprints
Dierauer, Hansueli; Siegrist, Franziska; Weidmann, Gilles.
• Lower accumulation of copper in the soil. • Less damage to microorganisms in the soil. • Potential saving in costs of spraying agent. • Improved distribution of spraying agent over the required period of treatment until exhaustion of the permitted maximum quantity. Practical recommendation Adapting dosage to state of infestation: As long as there is no infestation in a radius of 50 km, refrain from treating. Observe national information and alert services. As soon as the first case of infestation in the region is reported, protect potatoes with 200 to 250 g of pure copper per hectare. If potatoes in your own or neighbouring fields are afflicted by leaf blight, increase the dosage to 800 g and do not wait longer than a week in between treatments....
