In future, it will be necessary to deploy resources worldwide even more purpose-specifically and efficiently. That is why PÖTTINGER has teamed up the trailed TERRIA stubble cultivator with the AMICO F hopper for resource-saving work. The tillage and simultaneous seed or fertiliser application steps can now be completed in a single pass.
The TERRIA with distribution system can be used for both stubble cultivation as well as deep loosening work. Different deposit depths for the fertiliser allow different levels of soil to be supplied as needed. A total of three deposit depths can be set:
- Top placement: 100% top
- Mixed placement: 50% on top, 50% below
- Down placement: 100% below
The aim of the combined method is to loosen the soil and at the same time apply fertiliser, as it can be made best available to the crop by direct placement in the soil. Precise fertiliser placement prevents loss of effectiveness due to nutrient outgassing and run-off.
Nutrient deficiencies can be precisely compensated in different soil layers using this process. This promotes targeted root growth because the roots are attracted to the fertiliser. A strongly developed root system promotes plant growth and especially the density of the crop.
The wide tine spacing of TERRIA stubble cultivators ensures reliable operation even with high volumes of organic matter. The incorporation of harvest residues and cover crops is carried out using different types of share and is possible with wings. The fertiliser boots can remain permanently mounted.
The TERRIA with distribution system can be equipped with three different types of chisel points and wings depending on the stubble cultivation application. Examples for each of the three applications:
- Chisel point with wing shares and shin for top placement
- Chisel point with shin for mixed placement
- Narrow point 40 mm for deep placement
A full-area movement from a working depth of 6 cm is achieved with wing shares. Stubble and cover crops are reliably cut right through, and shallow fertiliser placement within a wide band of up to 80 mm is possible here. This variant is particularly suitable for shallow cultivation in spring, for example, phosphate compensating fertilisation instead of depositing fertiliser during precision drilling.
The chisel point is suitable for coarse loosening and breaking up the soil. Plant residues are thoroughly incorporated and existing furrow bottoms are broken up. The seeds can develop their root systems downward and to each side, so that the plant can absorb nutrients at all levels of the soil.
The narrow point guarantees erosion-reducing fertiliser placement to a depth of up to 35 cm. Harmful compaction is broken up, even in heavy, sticky soils so that clods remain in the soil. Primary tillage in autumn with deep placement of the fertiliser, for example, is perfect for preparing seedbeds for beets.
