Lesson 22

Text В

There are several ways of establishing a pasture. The radical method is to plow an old pasture, to cultivate it

until free of weeds, and to sow the seed into a clean seedbed. Complete cultivation allows the farmer to conser­ve water in the soil, and it has the oi'foct of reducing competition between the pasture seedlings and other plants such as weeds and native grasses. Cultivation also males some nutrients which benefit young plants more available.

Sub-surface sowing is a method of drilling seeds into an existing pasture with the aim of obtaining the partare of a needed composition. From 10 to 20 per септ; of the seeds.may be expected to germinate and grow when this me­thod is used. In general, grass seeds sown in this way cannot compete with the native plants, but the mothod is more successful with legumes.

Whichever (какой бы... ни) method of establishment is used, it is usually found that the species with large seeds are established more easily. The larger seeds carry more food and the seedlings grow more rapidly.

With all methods of pasture establishment best re­sults follow the use of fertilisers. If pastures are not fertilized at all weeds may become a problem. It is due to tho fact that v/eeds tolerate low soil fertility and will grow quite well in the soil which is too poor for" the growth of pasture plants.
