CTF workshop / strip-till in sugar beet<br />
Veit Nübel Gebietsdirektion Mitte / Rübenabteilung Ochsenfurt
<strong>Südzucker</strong> <strong>AG</strong><br />
Design of experiments<br />
Issue: corrected sugar yield strip-till = corrected sugar yield plow or mulch<br />
(Type of experiment: strip plots)<br />
usual system of the farm<br />
• plow<br />
or<br />
• mulch<br />
strip-till system<br />
• no stubble cultivation<br />
• strip till early autumn<br />
• sow in combination with prism rollers<br />
• use of glyphosate shortly after sowing<br />

<strong>Experiments</strong> <strong>Südzucker</strong> <strong>AG</strong><br />
Does strip-till lead to lower mineralization rates?<br />
strip-till plow tillage<br />
Organic material has higher sun reflection rates than soil<br />
-> soil stays cold longer in the spring !<br />

<strong>Experiments</strong> <strong>Südzucker</strong> <strong>AG</strong><br />
Chances and challenges<br />
Chances:<br />
� maximum aggradation and erosion protection<br />
� protect the water resources (dry areas)<br />
� economic or business benefits<br />
� no tillage in spring<br />
Challenges:<br />
�100% field emergence and equal corrected sugar yield<br />
� one step in fall from the stubble to seedbed<br />
� RTK-availability<br />
� tools for different soils and crops<br />
� guarantee nutrient availability of the plant<br />
� possibility for strip-till on hills<br />
� cover grop combining with strip till<br />
