PREVENTING SOIL COMPACTION
‚ Whenever possible, use low-pressure tyres on all machines operated in fields in order to reduce
superficial compaction.
Mounting wide tyres or twin wheels is not enough; the tyre pressure must be adjusted accordingly.
Aim for 0.6 bar, according to the tyre manufacturer's recommendations. As the E
ASYDRILL is a towed seed drill, it
exerts no weight on the rear tractor wheels and does not require counterweights to be mounted at the front!
ƒ Reduce the load per axle to avoid in-depth soil compaction.
Avoid loads over 6 tons per axle: if heavier trailers must be used, park them at the field entrance. Prefer lightweight
tractors: as the E
ASYDRILL requires little traction power, moderately powerful - and therefore lightweight - tractors
are sufficient.
„ Till on dried-out ground.
Be patient, and wait for the right time of year before starting tilling. According to scientists, as soon as drying soil
changes colour, it acquires greater resistance to compaction. After 4 to 5 years of conservation tillage, the ground
drains water faster and becomes more resilient, which reduces the necessary waiting time.
Provide calcium and magnesium to compensate for ground’s acidity where necessary.
Aim to maintain a pH of 6.5 - 7 to ensure optimal stability of the clay-humus compound.
† Enrich the soil with organic matter to preserve it from compaction and to increase its resilience.
Leave straw and crop residues on the ground, spread manure, grow fodder plants, and avoid ploughing.
BURYING THE STRAW
‚ Select a suitable variety.
According to the selected variety, the quantity of produced straw can vary, as well as its shock resistance. A variety
that is resistant to disease and which it is not essential to treat with a fungicide at the end of the season will also be
more easily decomposed by the fauna in the soil.
ƒ Prepare and adjust settings on the combine harvester
Tighten the thresher and increase the rotation speed to break straw better. Dry straw breaks more easily: under these
conditions, harvest the fields that you wish to sow first. The combine harvester must be equipped with a chaff
spreader. Shred the straw into chaff of 5-6 cm (sharpen the shredder blades, tighten all belts) and spread it evenly.
„ Shred the chaff and stubble behind the combine harvester.
In particular, if the catch-crop period is short, the cutting level is high, the chaff is poorly spread out and you wish to
till the soil with tools fitted with tines.
Thoroughly mix the straw on the ground and roll.
Do not bury the straw deeper than 5 to 6 centimetres below the surface in order to facilitate decomposition and avoid
mixing trash in. Rolling with a heavy roller improves the contact between soil and straw and facilitates decomposition by
the fauna in the soil.
PROTECTING CROPS AGAINST SLUGS
‚ Disc early to deprive slugs of food.
ƒ Till the surface to make the soil fairly fine, and roll to disturb slugs.
„ A long time before sowing, keep the soil clean by means of mechanical and chemical destruction.
Watch for the arrival of slugs with the first rains and set up traps if necessary.
† To ensure quick emergence, sow a little deeper, and in favourable conditions.
‡ Close the seed furrow well, and possibly roll after sowing. In a situation where the risk of damage from
slugs is high, treat with the appropriate product.
ˆ Watch over the crop well after sowing, especially in damp weather and soil conditions.
