Deep Soil Cultivation Prior to Sowing Oil seed rape with Chisel Plough Using Cutter-disc S

The Jiří Jetleb & Son farm manages about 680 hectares of mostly heavy soils in the municipality of Vrdy in the district of Kutná Hora. Last year, they asked their seller of agricultural technology, Agrometall Heřmanův Městec, for a machine that would solve the basic soil preparation before sowing oil seed rape as their standard tillage technology could not be used on a part of their land due to extreme drying of the soil profile. Agrometall leased the Terraland TN 3000 demonstration machine, with hydraulic protection of the working parts, and as Mr. Jetleb Sr. states, they would not be able to process 100 hectares for oil seed rape without the machine.

Overall, they used the machine for 200ha and they could already see an improvement in the condition of crops during autumn and spring in comparison with tillage technology. That was confirmed during harvest when the crops planted after the deep cultivation by Terraland showed higher yield. Therefore, this year they purchased their own Terraland TN 3000 HD7R chisel plough in the Profi version with the rear cutter-disc section. Thanks to the cutter discs, they can achieve perfect soil structure for sowing as early as after the first soil cultivation.

The machine operator, Mr. Radek Stoklasa says that working with Terraland is better than with a traditional plough.

The mean Diesel consumption for processing depth of 35 – 40cm is 18L/ha with an hourly output of 2.8ha.


When we came to look at the machine, they had processed about 100ha in Vrdy and Jiří Jetleb Jr. judged the machine with a smile: “We undercut at approx. 40cm while using 18 litres of Diesel per hectare on average, with an hourly output of 2.8ha. We learned last year what to expect from this technology and so far we assess its operation as very good and beneficial.” Richard Stoklasa, the tractor driver, used deep cultivation on a field called Tupárov right across from the Jetleb farm, with an area of 61ha. He said that they used to till the field before but that was usually very demanding with regard to energy consumption and inefficient.

The Terraland TN 3000 Profi chisel plough that provides ideal soil structure for sowing oil seed rape is at work on the Jetleb Farm.

A single pass of Terraland Profi creates suitable conditions for sowing oil seed rape.


They process soil at a depth of 35 to 40cm, disturb the subsoil compaction, all of which with lower fuel consumption and higher output. The field was harvested on 30 July, the winter wheat, Rebel species, reached an average crop of 7.7t/ha, and all straw was crushed and left in the field. Immediately after the harvest, DAM in the dose of 130kg/ha was applied, and shallow stubble cultivation with a disc cultivator was done. After ten days from the stubble cultivation, the field is processed by the newly purchased Terraland Profi. Just before sowing, the field is fertilised with NPK in the dose of 200kg/ha, incorporated by a share compactor, followed by a disc seed drill that will plant the oil seed rape. If they tilled the field, they would have to use a short disc stubble cultivator to adjust the furrows, and they would need at least two passes due to the heavy soil. Terraland saves at least two passes. The savings are not only in time, which there is never enough in this summer season, but mostly in the financial representation given by fuel savings in approx. 16 litres per hectare, and by savings in financial resources for the operation of the tractor and the driver. On the Jetleb Farm, that is a saving of about 100 to 150 thousand CZK in relation to the number of passes in the seedbed preparation, only for the seedbed preparation of 200ha of oil seed rape..

We would like to thank Mr. Jetleb Sr. and Jr. for their trust when purchasing the machine and we wish them all the best in the coming years.
