SMI COMMENT |
 |
 |
 |
 |
 |
Ploughing is the best option
for maintaining structure, optimal
cost for the size and type of the farming operation and use
with potatoes and sugar beet. There are good returns from
renting land to high value crop (carrots/onions) producers.
There is higher than average manpower due to
research/trials requirements. Surface profiling could reduce
erosion risks further. Leaving ex-potato ground unploughed
until late winter would reduce the volunteer problem.
There are adequate man-days for autumn establishment,
irrespective of type of year but insufficient for spring crops in
wet years. Localised damage can occur if soil is worked too
soon after heavy rain. |
