Kuhn Rm Field Shredders
Well shredded crop residues are a friend for your soil, fighting parasites and rapidly degrading organic matter. This is why KUHN offers the RM shredders intended for intensive work.
These machines are designed intensive work; their mechanics are sturdy with exceptional technological features.
This provides: Fine shredding and good spreading of the residues for a job well done, a field leader and easy transport with the folding models.
The RM shredder with horizontal axis is adapted for shredding crop residues such as cereal straw,
Sunflower or corn stalks, but also for the reclamation of « nitrogen trap » pastures and the upkeep of meadows.
The agronomic purpose of shredding
Shredding also means even distribution of crop residues or crop cover. This increase in contact surface between the organic matter and the scavenging micro-organisms allows speeding up the decomposition and thus:
- Fighting parasitism
Crop residues, especially grain corn leaf stalks, host pests such as pyale caterpillars, fusariose and helminthosporiose. Their development has harmful consequences on crops. A fi ne shredding followed by ploughing in using a soil preparation tool limits the health risk by destroying the support essential to parasitic development.
- Returning the nitrogen
During decomposition of the shredded residues, the scavenging micro-organisms consume mineral nitrogen for their growth. When they die, they return the nitrogen under the form of nitrates which can be absorbed by the crop.
- Maintain the soil structure
The shredding and incorporation of crop residues at shallow depth participate in maintaining the soil structure limit erosion and improve humid fertilization which is important notions in minimum tillage methods.
