The market for table ducks is steadily increasing, but egg layers are declining because of the strong flavour of the eggs. From four weeks onwards, ducks are reared outside, preferably on light sandy soils, as found in parts of Norfolk. Once again the outdoor system, particu-...

Although Jerusalem artichoke can grow on poor soils, tuber size tends to be small and yields are low. Jerusalem artichoke prefers fertile soils, which are necessary for high yields. The highest tuber yields are typically obtained in light, sandy soils of good fertility. Jerusalem artichoke is adapted to rich sandy loams and well-drained alluvial soils (Huxley, 1992).

Features such as mountains and large bodies of water restrict the spread of many pests. Other features of the landscape can have similar effects. Soil type is a prime factor affecting wireworms, grubs, nematodes, and other soil organisms. Some pests live in heavy, poorly drained soil, others in light, sandy soils. Soil type also affects the distribution of plants (including weeds), which in turn affects the population of insects and other plant pests. 

Prevention and Control Scab fungi thrive in light, sandy soils with a neutral or alkaline pH. Lowering the soil pH to below 5.2 will reduce the chance of disease. Start with certified disease-free seed potatoes. Rotate crops and plant resistant cultivars. Keep the soil evenly moist.

It is not recommended for use on light, sandy soils because of the hazard of phytotoxicity. In soils with a proportion of high organic matter it is strongly adsorbed and thus rendered ineffective. Weeds die 14-20 days after treatment. Combined with phenoxy herbicides it has a synergistic action.

Calcined magnesite (80% MgO). This is the most concentrated magnesium fertiliser, but it is only slowly available in the soil. To help to maintain the magnesium status of a light sandy soil which is naturally low in magnesium, 300 kg/ha should be applied, say, every four years in a predominantly arable cropping situation. 

TRV spread by free-living nematodes in soil, especially in light sandy soils. PMTV - spread by powdery scab fungus and can remain in the soil for years in fungal resting bodies.
