AGRICULTURE

Soils.—In the northern part of the state the sides of the higher mountains are steep and are in many places denuded of soil. In the valleys and on the hills north of the terminal moraine the soil consists largely of glacial drift, which is composed of clay, sand, and gravel mixed with bowlders. This soil is fertile, but a large part of it is not easy to cultivate, because of the large stones in It and because of the rugged surface. South of the terminal moraine, in the Highlands and in the Piedmont Plateau, the soil is composed of gravel and sand washed down by streams from the glacial deposits farther north and of disintegrated underlying rocks, which in the Highlands consisted largely of gneiss and in the Piedmont Plateau of sandstones and shales. The soil of the Coastal Plain consists of extensive deposits of gravel, sand, clay, and marl deposited in the ocean, which once covered this region. The gravel, sand, and clay were carried into it by the streams which flowed from the north. The marl consists largely of very small shells of animals that lived in the sea. This mixed soil is very fertile, particularly that in which there is an abundance of marl. This is found in the "Marl Belt," which is a strip of land extending from the Atlantic Highlands southwest past Trenton and Mount Holly as far as Salem. Its width varies, being widest at its northeastern end and becoming narrower and less rich in marl toward the southwest. Formerly marl was used extensively as a fertilizer to enrich poorer soils, but it has been generally displaced by the richer commercial fertilizers. The so-called "Pine Barrens" which cover a large part of the Plain, east of the Marl Belt, are comparatively unproductive, but by proper cultivation and the application of fertilizers, these areas can be made very productive.

Crops.—In the production of grain crops the state cannot, on account of its varied surface and its small farms, compete with the western states with their great plains and large farms. Wheat is produced mainly for local consumption. Corn is grown in large quantities in all parts of the state. Rye and buckwheat are also raised in limited quantities. Much of the land, particularly that which is not adapted to the growth of other crops, is devoted to pasture and hay. Many circumstances are extremely favorable to special agricultural industries whose products are vegetables, fruits, flowers, poultry, eggs, milk, and butter. These are: the climate, with its mild winters and generous rainfall; the fertility of the soil; the large permanent population of the state; the presence of thousands of visitors from other states at the summer resorts of the state; the nearness of the farm lands of the state to the great cities of New York and Philadelphia; and the excellent facilities for the rapid transportation of agricultural products to the markets.

The constant demand of the large cities makes market gardening very profitable, and this industry is carried on in all parts of the state, but with special intensity in those sections which are near the cities. All kinds of vegetables are raised. Of these the potato crop is the most valuable. In the southern counties, which have a sandy soil, large crops of sweet potatoes are produced. This section is also prominent in the cultivation of tomatoes, beans, and peas, great quantities of which are used in the canning industry.Cabbages, celery, and onions are valuable products. The demand for fresh, early vegetables has encouraged market gardeners to devote increased attention to growing vegetables under glass.

Fruits of all kinds are raised in all parts of the state. In the northwestern section of the state, in parts of Warren, Morris, and Hunterdon counties, peaches are grown in great quantities on the stony soil of the glacial drift which is not favorable to general farming. In the western section apples and pears are abundant. While strawberries, blackberries, raspberries, and grapes are grown in all parts of the state, they are grown in special abundance in the southern part of the state. In this section establishments for the bottling of unfermented grape juice have grown up. Huckleberries are common in the wooded sections of the northern and southern parts of the state. Cranberry bogs are found in Atlantic, Burlington, and Ocean counties.

Animal Products.—Dairy farming is successful in all parts of the state, particularly in the sections in which pasture and hay are easily obtained, and in which facilities for the prompt transportation of milk to the cities are at hand. Milk is produced not only by the general farmer but also by special dairy farms, which, by devoting special attention to the care and feeding of cattle and to the handling of the milk, produce milk of a superior quality. Poultry raising and the production of eggs are profitable. The poultry industry is especially extensive in Cumberland, Atlantic, and Ocean counties.

With the increase in the population of the cities the farm land of the state is growing in extent and value, but it is clear that more rapid growth is possible and desirable. The State Agricultural School at Rutgers College, with Its Experiment Station and practical courses of instruction, is doing much to improve agriculture in New Jersey.
