Sprinkle fertilizer

Spring 2020 was very wet. In the first 2 months there was 200mm of rain, so that basic fertilization of the grain that normally takes place around February 15, could now only be carried out in March. Due to the wetness, the grains were only mediocre. Several places in the field are flooded and other places are way too thin. As a result, we have also varied the basic fertilization in the grain this year by means of task cards. This task card is made with drone images and shows where the crops are good and / or bad. With this drone data and the Olympique strategy, we then made a task card where we fertilize the good places extra and the bad places less

In the video below you can see how the task card in the terminal controls the fertilizer spreader.

in 2019 we exchanged our old Rauch fertilizer spreader for the latest model. Technically, this fertilizer spreader has improved a lot, but a few new options are also possible in the software field. For example, we can now sprinkle separate quantities left and right via a task card.

In 2018 we made a nice video of the variable fertilizer spreading via the Fritsmeier Isaria sensor.

The over-fertilization in 2017 was carried out on the basis of the fritzmeier sensor data.

Also in 2015 we carried out our additional fertilization using the Fritzmeier Isaria crop sensors mounted in the front linkage of the tractor. During fertilizer spreading, the biomass and the nitrogen index are measured and used to calculate an advice. This is then immediately passed on to the fertilizer spreader, which then automatically adjusts the amount of fertilizer to the crop. In the film below you can see how we fertilized the potatoes in 2015.

We started the fertilization season with additional fertilization of the sugar beet. You can see that in the photos below.

In 2013 we fertilized the potatoes with the help of the Fritsmeier Isaria Sensoren. These sensors hang from a trestle in the front linkage and are folded out on the field. We have been testing for several years with these Fritzmeier Isaria Sensors and this season we fertilized the potatoes fully automatically based on the sensor measurements and a self-developed calculation rule. The Fritzmeier sensors not only view the crop, but also take into account the yield potential that we map with the EM38-mk2 soil sensor and the yield measurement on the potato harvester.

This year we exchanged the old Rauch spreader for a new Rauch Axis spreader. This too is hydraulically driven and can be operated via an ISObus terminal supplied with it. The new spreader is also equipped with a weighing system so that during filling it is immediately possible to read how much fertilizer is in the container. The dosing control is still done via the hydraulic system (EMC) so he does not use the weighing system for this. The spreader should also be able to spread on GPS with this spreader so that there is minimal overlap.

In 2009 we still spread the fertilizer with the Rauch hydraulically driven coastal fertilizer spreader. The Isobus computer is still not compatible with the ISO standard, so the link with GPS is still not available. The machine has already sown many tons of fertilizer and has still not been defective. the spreading pattern is also still very clear from the last spreading test we had carried out.

You can see the fertilizer spreader working in a beet crop in the film below.

In 2004 we bought a new fertilizer spreader. This fertilizer spreader has a volume of three tons and is hydraulically driven. By measuring the resistance of the oil flow, the amount of fertilizer is precisely measured.

The fertilizer spreader is controlled by an ISOBUS computer. This can be controlled by any ISOBUS terminal. So also through the Fendt Vario ISOBUS terminal. By changing the speed of the spreading discs, the working width can be infinitely adjusted from the cab. This also makes it possible to link the spreader to GPS in the future, so that work can be done with as little overlap as possible.

After planting the potatoes, additional fertilization is carried out according to the needs of the crop. We did this with an Amazon fertilizer spreader. This spreader had a capacity of 2200 kg and was equipped with a side disc.
