einboeck-presse-striegeln-01OPTIMAL AEROSTAR WEEDING EFFECT, PART I

Welcome to our new collection in the Einböck Newsletter! In the coming issues of our newsletter in this column we want to point out techn. details of our AEROSTAR, as well as practical hints in using / adjusting the machine in various crops.

Even when you already have some experience with our machine we hope that this sum up will help you to recall the positive effects of weeding and maybe show you new ways to use your AEROSTAR.
As you will see in the course of our collection, our AEROSTAR is a universal tool which is unbeatable not only in mechanical weed control, but has many additional positive effects in crop care and maintenance!

In today’s, first issue we’ll have a closer look at weeding in general, some techn. details as well as the first crops which are weeded in spring. In the coming issues we’ll show you the various components and options available on the machine. You will be surprised, which crops are (can be) weeded!

Many advantages of weeding

Mechanical weed control is not the only reason for weeding – there are many other, positive effects for the crop, support of tillering, soil, water- and oxygen balance,…

The main reason to use the weeder still is to mechanically control and regulate weeds; not only in organice farming, also conventional farmers (mainly on big scale) experience the economic advantage.

You will not be able to achieve a 100 % clean crop with the weeder; on the other hand, a certain amount of weeds has a positive effect on the crop.
Only approx. 1/3 of the regulated weeds is pulled out by the weeder; the main part is buried, damaged or hurt what hinders the weeds growing. Therefore the structure of soil is very important –this can be positively influenced during the tillage system prior to seeding.

The „weeding-effect“ is best:
+ the smaller / younger the weeds are (during germination or small-leaf stage the operation is most effective)
+ the closer to the surface the weeds germinate („floating“ prior to seeding and blind combing supports germination of the weeds)
+ the looser the soil is
+ the higher the working speed is
+ in sunny and dry weather conditions

Additional, positive effects of weeding:
+ loosening of the soil
+ breaking of crusts
+ aeration of the soil
+ preventing the soil to become muddy
+ collection of nutrient out of the air (up to 20 % reduction of nitrogen fertiliser)
+ regulation of the water balance:
Through the very shallow operation a thin, loose layer of soil arises, which drys out and prevents the sun from shining on the wet soil
Quick and efficient absorbtion of rain through the improved soil structure
+ support of tillering

The right time for weeding…
...depends on the crop!

There are crops, which are weeded before emerging („blind combing“), and later on in the various stages of growth. We’ll have a closer look at the various crops in the next issues of our newsletter!

Blind combing:

Blind combing – after seeding, before emerging of the crop – releases the first weed-pressure and gives the crop a lead in comparison to the weeds. Important is, that the seeds are evenly placed and the seeding depth is sufficient (it might be necessary to place the seeds a little deeper).

As there is very little time between seedbed preparation/seeding and blind combing, the weeds are still in the germination stage and can be fighted very effectively. Blind combing is effective before the crop becomes visible in the field.

Blind combing can be done on nearly all crops; in very quickly emerging crops (e.g. rape) it does not make sense / is not possible.

Weeding of winter crops:

Blind combing very effective – due to weather conditions not always possible. Tine position 3, very sensitive operation

In early seeded fields (when the crop reaches the 3-leaf stage and the weather still allows an operation in autumn) –Tine position 3, light operation

In spring as soon as possible (when the frost is gone; support of tillering, loosening of soil and aeration) – Tine position 2 or 3, little pressure on the weeder section

In 15 to 30 cm high crop (mobilisation of nutrients, fighting of late germinating weeds) – tine position 2, if necessary also more aggressive

Above mentioned points are based on practical experience and very much depend on conditions and the result can vary. Co. Einböck does not bear any responsibility on correctness and cannot bear any liability on damage on crop / machines!
