The kind of crops <strong>and</strong> the success with which they can be grown depend upon improvement in drainage. General farming is commonly practised <strong>and</strong> the main crops grown are hay, grain <strong>and</strong> pastures. Timothy, alsike <strong>and</strong> to a lesser extent red clover produce satisfactory crops. The yield of grain varies considerably from year to year <strong>and</strong> the best crops are obtained in dry years, whereas in wet years they may be a failure. Where these soils are used for pasture, their management entails chiefly the selection of water-tolerant plants <strong>and</strong> the eradication of weeds. Where artificial drainage is adequate t’hese soils are suit,able for peas, beans, flax <strong>and</strong> other specialized crops. Early crops cannot be produced on any of these soils because the l<strong>and</strong> is slow to dry <strong>and</strong> warm up in the spring. Superphosphate is the main fertilizer reeuired on these soils. When soil drainage is improved, barnyard or green manure applications are needed to maintain the level of organic matter. IV.

The Eastport’ s<strong>and</strong> usually occurs along t,he Lake Huron shore <strong>and</strong> is used as a site for summer cottages. The Breypen l<strong>and</strong> t)ype consists largely of rock outcrop -- <strong>and</strong> the small areas of soil occurring in association witJh the rock can be used for pasture, although their use for such a purpose’ is hardly feasible in most places. It) is considered that the Breypen l<strong>and</strong> t,ype <strong>and</strong> the Eastport gravel are best used for trees. The Bottom L<strong>and</strong> is generally used for grazing purposes. The requirements for tianagemerit of these soils entail chiefly the eradication of weeds, <strong>and</strong> the proper cant rol of grazing. V.

The muck soils are suited to intensive farming <strong>and</strong> especially to market gardening. The most productive muck soils are those that can be irrigated as well as drained. The organic soil is rich in nitrogen but lacks the mineral elements such as phosphorus <strong>and</strong> pot8assium, which must be supplied as commercial fertilizer. Since the organic layer on the marsh soil is much shallower than that of the muck it is not as well suitled to intensive farming. It is probably best used for forest,. 93
