3
Q
Describe how soil texture and structure influence the timing of soil cultivation
A
Soil texture:
Sandy soils can be cultivated throughout the year but spring is preferable to avoid the leaching of nutrients.
Clay soils are best cultivated in late summer/early autumn to enable the frosts to break down clods. Clay soils should not be cultivated when wet, waterlogged or frozen to avoid damage to the soil structure.
Soil Structure:
Sandy soils are very free draining and therefore compaction is less of a problem in winter. Tilth production may result in soil surface capping after heavy rain or the use of irrigation.
The structure of a clay soil is easily damaged by poorly timed cultivations and so should be cultivated in late summer/early autumn. When clay soils are wet or waterlogged the clay particles smear easily and compaction occurs.
4
Q
describe single digging (3)
A
- a primary cultivation technique which involves digging to one spade (spit) deep.
- The soil is inverted to bury the weeds and allow organic matter to be incorporated.
- It is carried out in the autumn on heavy clay soils to allow the frost to break down the aggregates (clods).
5
Q
describe tilth production (5)
A
- a secondary cultivation technique to create a fine crumb structure for seed sowing or planting.
- It involves the soil being roughly levelled by raking in two directions to break down the large aggregates.
- The soil is then consolidated (firmed) using feet or a roller to remove large air pockets prior to
- finally raking in two directions to create a fine level surface.
- The soil should not be worked when it is wet.
6
Q
effect of plant spacing on root vegetable crops. give examples (5)
A
- eg carrot, beetroot, parsnip, radish
- Normally, optimum plant spacing is critical to achieve uniform growth and maximum yield
- Close spacing results in competition for light, water and nutrients
- Plants are more susceptible to attack by pests and diseases when planted too close
- Excessive plant spacing wastes potential cropping area
- for baby vegetables eg carrots or beetroot, sow thinly and space at minimal intervals. Alternatively, the thinning can be used as baby veg.
7
Q
describe intercropping
A
the growing of a quick maturing crop between rows of a slower maturing crop e.g. radish growing between parsnip to make the most of the cropping area. The fast maturing crop is harvested before the slower crop matures.
8
Q
describe successional cropping
eg Radish ‘French Breakfast’
A
- the sowing of crops e.g. lettuce, radish, spinach at intervals of two to three weeks in the same area to ensure a regular supply of the crop.
- This also extends the cropping season and prevents gluts.
- protection can be used (fleece, polythene) and soil
warming to further extend season. - planting dates; choice of cultivars
9
Q
Describe the soil prep for production of a crop of leeks (3)
A
- The soil is single or double dug in the autumn/winter prior to sowing/planting to relieve any soil compaction.
- Bulky organic matter is incorporated and fertiliser with a high nitrogen content can be applied one month prior to transplanting the leeks at a rate of 70-100g/m2.
- Secondary cultivation is carried out prior to transplanting and includes; levelling the soil, consolidation and the creation of the final tilth by raking.
10
Q
Describe the method of sowing for for production of a crop of leeks (3)
A
- Seeds can be sown under cover from mid to late winter in a greenhouse.
- The seeds can be sown 1-2cm deep in seed trays or 3-4 seeds per module using a seed sowing or multi-purpose compost. The seeds are covered with compost and watered.
- Outdoors, seeds can be sown from early to mid-spring in a prepared seed bed.
- The seeds are sown thinly in drills 1-2cm deep and 15cm apart.
- The seeds are covered with soil and watered.
11
Q
describe how you transplant leeks (8)
A
- Leeks can be transplanted individually when they are pencil thick and 20cm in height.
- The tops of the plants and the roots can be trimmed before planting.
- Holes are made using a dibber 15-23cm apart and 15-20cm deep with rows 30-40cm apart.
- A single leek is dropped into each hole which is then filled with water. The soil is allowed to back fill naturally around the transplant to create a blanched stem.
- The bed is irrigated/watered prior to transplanting.
Modules are watered well before planting. - The modules containing 3-4 leeks are planted deeply by digging a hole with a trowel.
- They are planted 30cm apart in the row and 30cm between the rows.
- The leeks are watered well after planting.
12
Q
when is the optimum time to prune a plum tree
A
plums are pruned during late spring/summer to avoid infection from the fungal disease silver leaf
13
Q
describe how to fan train a plum
A
- A maiden whip or feathered maiden is planted 15-23cm away from a wall or fence which is fitted with horizontal wires 15cm apart.
- The aim is to create a fan shape which is achieved by removing the central leader to concentrate vigour on both sides of the tree.
- The laterals are cut back to strong buds to encourage side shoots (‘ribs’) which are tied in at an angle of 45° and gradually lowered to the horizontal

17
Q
how does susceptibility to frost affect the suitability of a site selection for outdoor food production (4)
A
- Susceptibility of a site to frost can cause frost damage to fruit buds and flowers, which can mean reduced yields
- seedlings can be killed
- sowing times are delayed as the soil is slow to warm up in the spring
- frost pockets at the base of a slope must be avoided.
18
Q
how does soil pH affect the suitability of a site selection for outdoor food production (5)
A
- Most crops will grow on a soil with a pH of 6.5 – 7.0 although some require a more specific pH.
- Blueberries prefer an acidic soil whereas brassicas require an alkaline soil to avoid club root.
- Although potatoes prefer a slightly acidic soil they will grow well in a neutral to slightly alkaline soil.
- Potatoes can be affected by potato scab in very alkaline soils.
- Problems with nutrient uptake can occur in soils with a low or high pH e.g. lime induced chlorosis in ericaceous plants that are grown in an alkaline soil.
19
Q
how does a slope affect the suitability of a site selection for outdoor food production (6)
A
- If a site selected for outdoor food production is on a slope there could be problems with soil erosion
- it may be difficult to work
- dry at the top and wet at the bottom with run off which could lead to a build-up of nutrients at the base of the slope.
- The top of the site would be exposed to wind
- the aspect would affect how quickly the site warms up in the spring.
- A south facing slope will warm up quickly whereas a north facing slope will be colder.

36
cross-pollination of apple crops: Flowering periods (6)
1. For successful cross-pollination it is necessary to grow apple cultivars that have the same flowering periods.
2. These may be early, mid or late season cultivars and can be divided into seven flowering groups.
3. Early cultivars/flowering groups can be cross-pollinated by other early cultivars or by mid-season cultivars as they overlap.
4. Mid-season cultivars/flowering groups can be cross-pollinated by all three seasonal cultivars as they overlap.
5. Late cultivars can be cross-pollinated by other late season cultivars/flowering groups and by mid-season cultivars/flowering groups as they overlap.
6. Crab apples are universal pollinators of apple trees as they flower over a long period.
37
cross-pollination of apple crops: compatibility (3)
1. Apple trees are not reliably self-fertile and need other apple cultivars flowering in the same period to cross-pollinate.
2. Apple cultivar pollen is only compatible with other apple cultivars.
3. Triploid cultivars are incompatible with each other and are poor pollinators as their pollen is sterile. They require two diploid cultivars for cross-pollination to take place.
