Williams, R.J. et al. (1996). Report of the Rosemaund Study—Describes the movement of herbicides through cracks and fissures in heavy soil into neighboring water courses following heavy rainfall. 

Wheat is a deep-rooted plant which grows well on rich and heavy soils and in the sunnier eastern and southern parts of the country. Winter wheat can withstand most of the frosty conditions of this country, but is easily killed by water-logged soil conditions. It needs a pH higher than 5.5. It is the best cereal to grow when the soil is highly fertile, so it should follow grain legumes and root crops... 

Cabbages have a wide range of uses. They are a useful food for all classes of stock and, when suitable varieties are grown, high value crops can be grown for human consumption. These can be fed to stock when the market price is too low. They prefer moist, heavy soils, and seasons with plenty of rainfall. 

One of the disadvantages of early phosphorus surveys was not long ago, the need to obtain a relatively large number of heavy soil samples, which had to be taken to a chemical laboratory for analysis. In later studies, however, use has been made of portable equipment that makes it possible to analyze, even in the field, very small samples, and statistically appraise the analytical results (Persson 1997).

Transfer the soil sample to a suitable metal tray to form a thin layer and, as far as possible, remove any stones present. With very heavy soils it is necessary to break any clods between the fingers. Dry the soil by placing the tray in a current of air at a temperature not exceeding 30°C. With large numbers of samples it is convenient to place the trays on a series of metal racks over which air may be blown from thermostatically controlled fan heaters. Continue the process until the soil feels quite dry. If the soil appears to contain moisture after grinding, return it to the drying rack. 

Compaction occurs when soils are regularly walked on or cultivated in wet conditions. It is a particular problem in heavy soil. Avoid it by creating paths that follow the routes you want to take around the garden, and planting beds that are narrow enough to be worked on from paths. Regular use of a mechanical cultivator can also create compacted hard pan below the soil surface that plant roots cannot penetrate. 

Bulky materials of living origin maintain and improve soil structure—helping light soils to hold on to food and water, and heavy soils to drain more effectively. They may also supply plant foods, released as they are broken down by soil-living creatures. 

To improve structure Winter rye, for example, with its very extensive fine root system, improves heavy soil by opening up the structure in lighter soil, the roots bind with soil particles, helping them hold water. 

In heavy soil in particular, birch, cherry, apple, pear, and plum should be planted no less than 12 ft (4 m) from the house. Ash, false acacia, chestnut, linden, sycamore, maple, and willow trees should be planted no less than 22 ft (7 m) away, while oak and poplar are safest kept at a minimum distance of 40 ft (12 m) from the house or garage. 

IDig a generous hole around 18 in (45 cm) deep, or twice as deep as the rootball. In heavy soil, gently fork over the base and sides of the hole to allow the roots to penetrate. Soak the rootball of the plant well before planting. 

Edging provides a neat, defined boundary between bed and path. It contains the soii on the bed, and any muiching material on the path. Edging is to be recommended for medium to heavy soil where the level of the bed tends to rise above the path. Where topsoil is thin, edging allows the bed to be built up with soil and bulky organic matter. Raised beds are especially useful where drainage is poor. 

It comes as no surprise, perhaps, that fruit prefers deep, rich loam that is free-draining but moisture-retentive. You may not have these conditions at first, but much can be done to improve soil structure, open up heavy soil, and increase the water-holding capacity of light soil (see The Soil, pp.34-35). If starting with very poor soil, start to improve it a year in advance of planting fruit trees or bushes. 

In the direct drilling (no-till seeding) practice in the united Kingdom/ straw residues from the preceding crop are usually burnt because poor crop establishment and yields can result/ particularly on heavy soils in wet years (10). Similar problems can occur in the conservation tillage systems oF the Pacific Northwest (L.F. Elliott and H.-H. Cheng/ this volume). 

Sandy soils, with low amounts of organic matter, are most common in deserts. As such, they may release the adsorbed chemicals more readily than will heavy soils rich in organic matter. 

The dislodged residues may not remain in the pump chamber. After cleaning is completed check the pump for operability by slowty turning the impellers by hand. There may be no resistance to rotation. It is generally not necessary to dismantle the roots pump. If this should nevertheless be required due to heavy soiling, then it is highly advisable to have this done by the manufacturer.

Revolution hardly became established, rather, so called traditional agricultural methods by default that lead to heavy soil erosion, remained predominant until today.
