2/18 Flashcards
Limitation of poor soil structure.
Restriction of gaseous exchange at root level.
May reduce the roots’ ability to access nutrients.
Restriction of development of root crops.
Limitations of soil depth
Shallow soils will mode the root establishment of fruit trees.
Shallow soils will limit the growing of root crops.
There will be a lack of anchorage casing wind rock.
Limitations of North Facing Aspect.
Soil may be cold.
Will receive lower light levels.
Frost potential is increased.
Limitation of exposure to wind.
Causes physical damage to crops.
Discourages pollination insects from flying.
Can cause/contribute to soil erosion.
Limitations of availability of water.
May need to install water buts or rain harvesters.
Lack of water will result in poor and/or reduced crop yield.
May need to transport water from else where.
Sowing seeds in modules.
Courgette ' Defender' can be sown in clean/sterilised modules. Use John Innes seed sowing compost. Sow on or two seeds per module. Sow seeds on their sides. Backfill with compost. Water and label.
Direct sowing in drills.
Seeds are sown in a soil with a fine tilth.
Carrot ‘Vita Longa’ are sown in a ‘v’ shaped drill which is drawn with the back of a rake against a garden line to a depth of 13m.
Water bottom of drill.
Sow seed thinly and evenly along the length of the drill.
The soil is drawn back over the drill and labelled.
Planting onion sets.
Onion ‘Red Baron’ planted early to mid spring in weed free soil that has been cultivated to a fine tilth.
Plant in rows - rows should be 25 - 30 cm apart.
Onions should be 7.5-15cm apart in the row depending on cultivar.
Push onion sets in soil so that tips are at or just below soil level.
If not planted deep enough birds may pull them out.
Water and label them.
Harvesting onions.
Harvest late August/early September when the foliage starts to die down and bend over.
Harvest on dry sunny days.
Lift onions carefully lifted from the soil using a fork.
In dry weather onions can be left to dry on the surface of the soil.
In damp weather onions can be dried in slatted trays in a greenhouse or shed.
Skins should be paper dry.
Discard diseased damaged onions.
Remove roots and too growth once onions are dry.
Production of ‘baby’ veg.
‘Baby’ vegetables are produced by closer crop spacing or by using the ‘thinners’ from a crop when thinning a crop to the final spacing.
‘Baby’ vegetables can also be intentionally grown by sowing thinly and spacing the crop to minimum distances.
Suitable for carrots and beetroot.
Uniformity.
Correct final spacing will result in a uniform crop of equal size and quality.
Spacing a crop too closely will cause competition which will result in a poor quality crop of uneven size.
Crop Yield.
Correct final spacing will maximise the crop potential and should result in a high yield.
Excessive spacing wastes potential cropping area and reduces potential yield.
Spacing a crop too closely may make the crop more susceptible to pest and disease attack which will result in a poor yield,
Dessert Apple Cultivars.
‘Beauty of Bath’
‘Discovery’
‘Jame Grieve’
Culinary Apples
‘Lord Derby’
‘Bramley’s Seedling’
‘Grenadier’
Factors to be considered when choosing an apple cultivar.
Dessert or culinary. Taste of apple. Disease resistance. Early, mid or late season varieties. Rootstock choice. Ultimate size of tree. Storage capabilities.
