Subsoilers
Subsoilers are machines designed for particularly deep cultivation. They consist only of a row of long ridges ending in chisels. A roller behind the row of ridges or support wheels in front of the ridges are used to set the working depth. The subsoiling procedure is usually carried out after harvesting the main crop, after stubble. The main task of the subsoiler is to loosen the soil in the deeper layers and break up the so-called plow sole. This procedure is intended to aerate the soil. Thanks to this, the successor plant develops its root system better and easier, and can take nutrients from deeper parts of the soil. AGROLAND subsoilers also work well on fields that are particularly wet, where there are stagnant water spots. The optimum working depth of subsoilers is between 40 and 60 cm, while the speed to be maintained during operation varies from 6 to 10 km/h.
Chisel plows
Chisel plows are machines also designed for deep cultivation. They consist of two rows of long ridges with undercuts ending in chisels, and a double collar roller. Chisel plows, like deep plows, have a very similar task, to loosen and aerate the soil well in the deeper layers. The main difference between the two machines is that subsoilers aerate the soil without interfering too much with the top layer, while chisel plows, thanks to the use of lateral undercutters on the ridges, further mix the top layer of soil. As a result, the field after the chisel plow can be successfully sown. Chisel plows replace standard plows well. The soil is sufficiently loosened for the following crop, and on lighter soils it is not turned enough to prevent evaporation and thus loss of water, which sandy soils particularly need. Chisel plows do their work best when plunged to about 35 to 50 cm at an operating speed in the range of 7 to 10 km/h.
Manufacturer of subsoilers and chisel plows – AGROLAND
AGROLAND, based in Skomlin, offers a wide range of subsoilers on straight and profiled ridges, MICHEL type, as well as chisel plows. These machines have definitely higher power requirements, so for a TYTAN PLOW subsoiler on a MICHEL-type tine with a width of 2 m we need a tractor with at least 120 horsepower, while for a TYTAN subsoiler on a straight tine with a width of 2.4 m within 140 horsepower. AGROLAND also has a TYTAN PLOW COMBI subsoiler model with an additional hitch at the rear, to which we can hitch another machine. In the case of the MAHIT chisel plow, the power requirement for a machine with a working width of 2.5 meters varies between 160 and 220 horsepower, depending on the type of soil being cultivated. As standard, AGROLAND subsoilers and chisel plows are equipped with pegged (breakaway) protection of the ridges, while for fields with more stones we recommend choosing hydraulic protection. AGROLAND machines are successfully used in difficult conditions in Western Europe as well as in various regions of Poland.
