Sandy Soil\nEasy to cultivate and warm up quickly in spring. It drains well so the plants do not stand with their roots in water for too long. However, as it drains quickly, plants need to be regularly watered and fed if they are to thrive.\n\nSilty Soil \nThis soil type is richer in nutrients than sandy soil. It is also heavier because it can retain moisture and has a tendency to become compacted. It does however tend to drain well and much easier to cultivate than clay.\n\nClay Soil\nWeighty to lift and difficult to work. Drainage is usually bad; the soil is acid and clinging to the feet in wet weather. When preparing the beds for vegetables in clay soil, the organic fertilizer should be added at a rate of two bucketfuls to the sq. yd.\n\nLoamy Soil \nContain sand, silt and clay, in such well-balanced proportions that none produces a dominating influence. These are amongst the most fertile soils. Almost any crop can be grown in them. They warm up quickly in spring and rarely dry out in summer.\n\nChalk Soil\nIt fertility depends largely on the depth of soil overlaying the chalk bed formation. If the topsoil is thin the ground will be poor and hungry. It will be bone dry in summer and the plants will need far more watering and feeding than on any other soil. If however, it is fairly deep, good growing conditions are possible.\n\nPeaty Soil \nIt occurs in fen or boggy areas. Peat is composed of excessive quantities of humus and is associated with water-logging. The soil is usually very acid and contains few nutrients. It does have one advantage in that it warms up quickly in spring. It is excellent for plant growth if fertilizer is added.

Rubber is an elastic hydrocarbon polymer which occurs as a milky colloidal suspension (known as latex) in the sap of several varieties of plants. Rubber can also be produced synthetically.\n\nExplanation\nSynthetic rubber is made through the polymerization of a variety of monomers to produce polymers. These form part of a broad study covered by polymer science and rubber technology. Its scientific name is polyisoprene.\n\nSources\nThe major commercial source of natural latex used to create rubber is the Para rubber tree, Hevea brasiliensis (Euphorbiaceae). This is largely because it responds to wounding by producing more latex. Henry Wickham gathered thousands of seeds from Brazil in 1876 and they were germinated in Kew Gardens, England. The seedlings were sent to Colombo, Indonesia, Singapore and British Malaya. Malaya was later to become the biggest producer of rubber.\n\nOther plants containing latex include figs (Ficus elastica), euphorbias, and the common dandelion. Although these have not been major sources of rubber, Germany attempted to use such sources during World War II when it was cut off from rubber supplies. These attempts were later supplanted by the development of synthetic rubber. Its density is 920 kg/m3.\n\nYou could get more information from the link below...

Natural rubber is made from the latex collected from the Hevea tree.\n\nSynthetic rubber is made through the polymerisation of a variety of monomers to produce polymers.

Rubber comes from a tree and plastic comes from oil. Therefore rubber is "natural" and plastic is not.

I believe rubber is the actual product, natural, derived off of trees, plastic is petroleum based and/or manufactured.

Depends entirely on the type of rubber, age, exposure to the elements, etc.  It is so widely variable there really is no answer.

you mean rubber, right?\nummm, what about the kind made of corn? it's biodegradable
