1. What do differences in productivity of land resources result in?

2. What is the main task of agriculture?

Resources for Farming

Our country has 22275 million land hectares of land resources and only 27 per cent (about 601,4 mln ha) have characteristics for agricultural production. Land resources for farming must have soils sufficiently retentive. They must be level enough to allow the use of machinery. The climatic conditions are to be good enough for crop production. The extent of agricultural land is not fixed. It changes as new techniques are discovered.

It was, for instance, impractical to cultivate low yield virgin lands where were no large machines. Land with infertile but physically favourable soils have become more valuable when large tractors and other machines had appeared. Better sources of power have made irrigation practical in places where formerly it was impractical. Nevertheless differences in productive capacity of land resources are tremendous. On the desert we can produce almost nothing, on some lands that have plentiful water, productive soils good location in relation to industrial centres we can produce several thousand roubles worth of products from a hectare in a single year. So the general principle is each hectare of land should be given to the use in which its economic productivity is the highest. The main task is to raise productivity of our land resources.

V Прочитайте текст "Land Reclamation and Improvement".Письменно ответьте на вопросы:

1. What lands need reclamation and improvement?

2. What can the purpose of drainage be achieved by?

Land Reclamation

There are many lands that are unfit for cultivation because they are too wet or dry. These lands need reclamation and improvement. There are different ways of reclaiming and improving such lands. Drainage and irrigation are the most common practices. The purpose of drainage is to increase the productiveness of agricultural soils.

This purpose can be achieved by removing the free water which excludes air and inhibits the growth and activity of plant roots. Drained soils are more easily and sooner worked. Drainage insures a longer growing season and earlier ripening. The useful action of microorganisms is stimulated, and there is a more rapid liberation of plant food. Irrigation is an important practice in arid regions where the annual rainfall is very low.

All crops need water very much. Some crops are more drought-resistant, others are less drought-resistant. Plants with a long growing season - sugar-beet, potatoes and especially grasses - require more water than cereals. Irrigation is especially useful for orchards.
