Our agriculture

The arable land is ordered primarily with wheat, barley and canola.

Furthermore, 10% of the arable land created with flowers for the bees and other animals. These are moved once a year or grazed by sheep.

Because of our machinery group the machines have become larger, so the cost has been reduced and the processing can be overcome besides work. In the main working hours the farmer takes the holidays and the previously accumulated overtime reserve.

Management begins with the preparation of the fields. (Seedbed preparation) rushes straight at the very rape, this must be sown in August thus it has plenty of time to onset of winter to 8 until 10 sheets form. Is the only way to ensure it survives the harsh wintertime. Is the rape sown, the tillage start for the sowing of barley. This must be done by the end of September, so that the barley is planted enough going into the winter. End of October then the wheat is sown.

The topsoil must be prepared for the new seed crumbly.

This happens with us no longer with the plow, because it is very time consuming.

We work the fields first flat with the disc harrow down to 10 cm, so the volunteer grain and weed seeds are to germinate. At the same time the short cut straw is incorporated as food for earthworms and other soil organisms.

After the rising of weeds, grasses and volunteer cereals or rape another step follows the subsoil to approximately 15 to 20 cm. Thus the soil is loosened gently that straw mixed intensively with the ground. The moisture is retained well. By adopting this approach, the soil erosion is also greatly reduced.

When this is done, the fields are sown again.

Equipped with a rotary harrow with a pneumatic seed drill with double glazing and trailing roller bands, the seed is placed optimally into the ground.

After about 8 to 14 days the young plants come from the soil.

Depending on the crop, the surfaces must be checked again on weeds and pests, snails, lice and flea beetles which can damage the young plants strong.

The plants always need food in the form of fertilizer. This is done by using the liquid fertilizer (Amoniakharnstofflösung). The AHL is applied with the sprayer. Again, different operations could be combined (Foliar treatment against powdery mildew) so you can save some crossings over the field.

Of rape

This is a plant where oil will be pressed.The oil can be purchased at our farm in different variations. The oil is cold pressed high quality and can be used perfectly in the kitchen. It has a walnut taste. In 100 g of rapeseed oil are approximately 7 g saturated fat, 62 g monounsaturated fatty acids (mainly oleic acid) and 29 g containing polyunsaturated fatty acids. The rapeseed oil is also used in cogeneration plants. This is a combined heat and power couplings for power generators. The heat generated can be immediately used for heating.

Or sold to industry, here it is added to the diesel fuel. The rapeseed cake (the rest of the pressure remains) will be very happy (a very valuable source of protein) fed to animals, this can avoid some soya imports from third Countries.

Here you can see how the individual plants develop.

It can be grown in the fall as winter wheat or it is sown in the spring as summer wheat. We build with us almost in winter wheat, which is in our latitude robust and profitable. It is produced in different qualities. For bakeries as bread wheat, as well as feed wheat or wheat for beer.

Also, it can be sown in autumn or spring. The winter barley is intended mainly to feed animals. The spring barley is used for malting for beer production.

How the grain looks like when it is ready for harvesting. It bends the ears during drying. To store it, it requires a certain ripening of the grains. To determine this a few grains where put in an instrument that can show us the moisture. Rape can be threshed and stored with moisture content below 8% water. Wheat and Barley can be stored  below 14% water. These values must be observed in order to prevent artificial drying.

If you don’t keep these values, it may be that when storing the harvest is poor. It needs to harvest at least 4 - 5 days nice sunny weather. After a thunderstorm you need depending on rainfall again 2 until 3 days nice weather to harvest, so that the grains are dry. With the threshing is usually started around noon to let dry the morning dew. You can imagine that it has been a challenge in the last few years to harvest in time.


Left: Winter wheat threshing | Right: Combine harvester. Here you can see how the reduced straw falls back onto the field.

Here you can see how the grains are transferred under the ride to lose no time, it takes a certain amount of tact.

Our grain warehouse is located in the Great machine shop. Here, much of the crop is stored and sold at a later date. At harvest, the waiting times for delivery to the warehouses are very long and the prices you can get are small.

The cycle begins again.

We look forward to you
