| Winter Wheat |
| Comment
on current growth stages |
Field
conditions |
| Very
little recent growth with forward crops remaining at GS 30 - later
drilled crops at 25-29. Some manganese deficiency now starting to
show. Soil Min N results so far show significant drops compared with
last year typically 31 kg/ha N in top 60 cm after rape. |
Total
sodden fields and each mm rain just tops up any that has run off.
Frequently wet patches in fields, ponding on headlands etc. Some
crops starting to yellow a bit with wet feet. |
