Group meeting - 26 April
Summary of group meeting – 26 April 2010
Agenda for the evening
- Update of farm activities
- 52 cows calved.
- 220 sheep lambing over March & April – scanning at approx. 200 percent
- Cows and calves were put back to grass over 5 – 9 April
- Turnout weight for weanlings ranged from 308 to 370 KG
- Steers gained 0.5KG/day DLWG on silage only over the winter.
- Heifers gained 0.28KG/day on silage only. They were wintered at the out farm, feeding on older silage swards.
- Update on soil analysis, benefit of lime and levels of fertiliser applications depending on soil fertility.
Stop 1 – Lower Carnreagh Road
- 19 acre block of grass closed off late October for turnout of cows and calves.
- Ground has been reseeded over the past four years.
- The ground is now divided up into six paddocks for rotational grazing.
- ½ bag Urea applied in early March.
- Grass covers are good despite winter and spring conditions with approx. 14 days ahead of stock.
- 17 cows and calves currently grazing the 3rd paddock, having been put to grass on 9 April.
- Scott Laidlaw from AFBI is monitoring clover plots on farm every two weeks and remarked how well the field has performed this spring.
- The field has the highest clover content and highest growth rate of the five clover check farms, despite the highest altitude (550 feet a.s.l)
- This has been accredited to a young sward and tight grazing autumn before closing and in spring.
- The main topic for the stop was grazing management of grass, maintaining grass quality and a fertiliser plan for the season.
Action for this year
- The field should get another 20 – 25 units of nitrogen over May, applied on each paddock after grazing. No more nitrogen will be applied thereafter.
- This should help the clover content in sward. Last season, clover was hindered by late fertiliser applications.
- Grass growth will be monitored on grazing ground using a plate meter to measure growth and match stocking rate accordingly.
- Field to be grazed tight to an average of 4 cm before moving stock. This will ensure high grass quality and encourage clover tillering.
- If grass gets too strong at any point, the paddock will be closed for baling.
Stop 2 – Field 5 (Big Hill) 8.5 acres
- Cold spring has delayed work by four to five weeks.
- From the last meeting, the field was to be sprayed off and heavily grazed down by sheep, with the stock exposing the soil for direct reseeding
- The field was to be seeded in 2 halves to compare the einbock and guttler seeders.
- Field has been sprayed off five days.
- Soil test showed the field to half a P & K index = 1.
- Half of the field was been aerated by a shakerator and responded well over the winter to the treatment, in comparison with the half that wasn’t aerated.
- A demo was carried out using a grass rake to discuss options for creating a seed bed.
- Various inputs into discussion for the field from ploughing, relieving soil compaction, aerating the full field, powerharrow and discing the field.
Action to be taken
- The remainder field should be aerated using the shakerator to relieve any compaction, rather than ploughed.
- The field will be disced and then sowed out in 2 halves to allow comparison between sowing methods using grass stitchers.
- The monitor farmer is keen to get the field back into grazing this summer, so stitching is the best option due to steepness of the field and uncertainty of weather.
- A permanent grass mixture will be sown, consisting of intermediate and late varieties and white clover.
Stop 3 - Fields 15 and 16 (6.9 acres)
- The field is in grass since early 90’s and continually cut for silage.
- 2 cut system and yields have dropped in the past few years.
- Due to poor fencing, stock rarely graze the ground. As a consequence, the perennial ryegrass content is low, with grasses such as Bent taking over.
- The fencing is being addressed to make better use of the field for stock, as field is reasonably dry.
- The poor winter caused any grass cover to die off, leaving a white mat in place. This was grazed off by young heifers over April.
Action to be taken
- The field will be soil tested to determine lime and P & K status.
- It will be slurried and fertilised as per normal when closing for silage.
- After 1st cut silage, the field will be reseeding with a mixture of perennial ryegrasses to suit both cutting and grazing (diploids and tetraploids).
- 3KG of red clover will also be seeded, along with the standard 1 KG white clover.
- This will ensure that if the red clover does not establish, there will be a good ryegrass and white clover sward in place.
- The options put to the monitor farmer were
- Spraying with glyphosphate before cutting, then drilling straight after with new grass.
- Spray and ploughing after silage.
- Direct drilling after silage.
- It was agreed, that an autumn reseed would be too late for red clover and that after 1st cut would be a better time.
- The monitor will make the decision based on how the season progresses, grass supplies on farm and weather conditions.
