Part 16

Nearly all of the type is in cultivated crops or pasture. The original timber growth was oak, hickory, and walnut; but little of this stands now, except on occasional woodlots. The Cecil loam is a soil which with careful treatment makes a fine farming land; but carelessly managed it very quickly deteriorates.

Cecil Clay.

The soil of the Cecil clay consists of a heavy loam, red or brown in color, and having an average depth of 8 inches. The subsoil generally consists of a red clay, although it is sometimes a heavy clay loam. The surface is generally free from stones, though occasional small areas have a few quartz and granite or schist fragments. In the Piedmont areas small rounded diabase fragments occur on the surface. Occasionally on steep slopes or high knobs the soil covering has been washed away, leaving the heavy red clay exposed on the surface. These areas, however, are small.

The type occurs principally in the intermediate valley of the Catoctin Belt, between the Blue Ridge and the Catoctin Mountain, and on the west slopes of the Catoctin Mountain. In the valley it occupies several small, disconnected areas scattered throughout this region, while on the west slope of the mountain it is found in one of two long, broad areas, extending in a northeast and southwest direction. Three small areas occur near the southeastern corner of the County, and the type is here closely related to the Iredell clay loam.

The most typical areas of this soil occur in the Piedmont Plateau and on the gentle slopes at the foot of the Blue Ridge in the vicinity of Bluemont.

This soil type has excellent surface drainage and is well watered and drained throughout by small streams. Few of the slopes are so steep as to wash badly. The heavy clay subsoil retains ample moisture for plant growth and the soil is rarely so wet as to necessitate tile draining, although this would undoubtedly be very beneficial in the case of the heavier phases.

The whole of this soil is under cultivation and it is highly esteemed wherever found, being naturally a strong soil and susceptible of improvement. The original forest growth consisted of oak, hickory, and walnut. The land is easily improved, retentive of moisture and manure, and with careful management makes an excellent soil for general farming. Owing to its tendency to bake, crops are liable to suffer during drought.

The land produces wheat, corn, grass, clover, apples, and pears. It is a strong wheat soil, and yields from 15 to 25 bushels per acre and occasionally more. Grass and clover hay yield at the rate of 1-1/2 to 2-1/2 tons per acre, while from 40 to 60 bushels of corn per acre are usually produced in good seasons.

All things considered, the Cecil clay is best adapted to the production of wheat and grass. The more loamy phases are adapted to corn, but the type as a whole is a much better wheat land than corn land. The soil is also well adapted to apples and pears. Bluegrass grows well and makes fine pasturage, and stock raising and dairy farming are other industries to which the Cecil clay is well suited. Care has to be used in the cultivation of this soil, for if worked when too wet it dries in large, hard clods that give trouble throughout the season and interfere with cultivation for a long time afterwards.

Cecil Silt Loam.

The surface soil of the Cecil silt loam consists of 12 inches of a light gray or white silt loam. This material is underlain by a subsoil of yellow silt loam slightly heavier than the soil. The type is locally termed "white land," and is closely related to the Penn loam and the Iredell clay loam, these types surrounding and grading gradually into it. In some areas the soil is quite free from stones, while in others from 10 to 30 per cent of the soil mass is composed of small rock fragments.

The type occupies several small areas in the Piedmont region, in the southeastern part of the County. The largest of these areas lies about 2 miles east of Leesburg, and a considerable part of the type is adjacent to the Potomac River. It occupies high, rolling, ridgy, or hilly lands, and has some rather steep slopes, though in general the surface is only gently sloping.

The drainage is good, but wherever the slopes are steep erosion proceeds rapidly, making gullies and washed-out places that hinder or entirely prevent cultivation. The type is well watered by small streams which flow the year round.

Probably one-half of this type is cultivated. The remainder is covered with a growth of scrub oak, pine, and some cedar. The soil is thin and only fairly productive, and consequently is not greatly desired for agriculture. It is very easy to work, but has to be cultivated carefully to avoid washing. The crops raised are corn, wheat, grass, and some apples. Corn yields from 25 to 35 bushels, wheat from 12 to 15 bushels, and clover and timothy hay from 1 to 2 tons per acre. Small fruits and vegetables do well.

Although naturally a thin soil, the Cecil silt loam is fairly well adapted to the production of the crops just named. Of the small fruits, peaches, plums, and berries do best. On the whole the type is considered much better adapted to wheat than to corn. It is limed and fertilized to a considerable extent, and responds well to such applications.

Cecil Mica Loam.

The Cecil mica loam consists of 12 inches of a friable, micaceous yellow or yellowish red loam, underlain by a yellow or yellowish-red loam, whose mica content increases with the depth until at 24 to 30 inches the subsoil is little more than a mass of small mica flakes which gives it a loose texture. Occasionally the subsoil is a clay loam for several inches before grading into the unweathered mica particles.

On the surface there is from 5 to 40 per cent of angular quartz fragments, ranging from 1 to 6 inches in diameter, some being much larger.

The Cecil mica loam occurs as one long, narrow strip, occupying the lower, gentle eastern slopes of the Catoctin Mountain. The southern end of the strip begins a short distance north of Leesburg, and extends in a northeasterly direction to the Potomac River, opposite Point of Rocks, Md.

The topographic features of the Cecil mica loam consist of gentle and occasionally steep rolling slopes. The surface is well drained and on the steeper slopes the soil washes badly and deep gullies are formed. In a season of moderate rainfall the soil and subsoil retain considerable moisture, but in dry weather crops suffer from drought.

No farms are found entirely on the Cecil mica loam, but those farms of the Piedmont, extending up the mountain slopes, generally include some of this soil. Such areas are often farmed, but more generally used as woodlots. Where cultivated the yields are scant, except where the soil is heavily fertilized. Corn yields from 10 to 30 bushels per acre and sometimes more, and wheat from 6 to 12 bushels per acre. The type is best adapted to forestry, chestnut orcharding, and grape growing.

De Kalb Stony Loam.

The soil of the De Kalb stony loam consists of a yellow or gray sandy loam of coarse texture, having an average depth of 12 inches. The subsoil consists of a heavy yellow sandy loam to a depth of 24 inches or more, where it rests upon a mass of sandstone fragments. These sandstone fragments and bowlders occur in varying quantities throughout the soil and subsoil. Where the fewer stones are found the soil is not so sandy, but a light loam, yellow or brown in color, underlain by a deep yellow loam subsoil.

The De Kalb stony loam is a mountain soil, occurring in long, parallel bands of varying width, extending in a general northeast and southwest direction, and mainly occupies the crests and slopes of the Blue Ridge and Short Hill mountains. It also occurs in smaller areas on the crest and east slope of Catoctin Mountain.

On the Blue Ridge and Short Hills the De Kalb stony loam covers the whole of the mountains, and here the physiography consists of long, sharp, rock-crested ridges, with steep, rugged slopes and occasional cliffs and huge ledges. There are occasional benches on the mountain sides, and here there is an accumulation of two or three inches of a black mold, resting on the broken sandstone fragments, and covered with a growth of locust, oak, and berry vines.

Owing to the steep and rugged surface of this soil, together with its stony character, superficial drainage is rapid and thorough, the water rushing in torrents from the mountain slopes, while as a result of the loose texture and the large number of stone fragments in the soil the water passes rapidly through it, and there is never an excess of moisture in the soil or subsoil.

On account of the steep and stony nature of the De Kalb stony loam little of the type can possibly be cultivated. The soil is naturally a very thin one, and is not capable of producing fair yields except in its less stony phases.

The principal growth on the type is chestnut, oak, and some pine. Probably 95 per cent of the type is uncultivated, and is valuable only for the timber growth it supports. Where cultivated the average yields per acre are as follows: Corn, from 10 to 20 bushels; wheat, from 6 to 10 bushels. Apples and especially peaches do fairly well on the mountain phase where not too stony.
