A Soil Analysis Of The Mid-Atlantic Area
The first soil analysis installment covered the New England states. Now, we are moving on to a soil analysis of the Mid-Atlantic states.
It wouldn’t hurt to catch up on soil basic by checking out “Soil Analysis Across The Globe.” This article covers just how dirt has been created – and it gives a very understandable treatise on soil horizons – or, the different layers that make up Mother Earth in our own neck of the woods.
Mid-Atlantic soil is much like the soil of New England – since glaciers during the ice age covered most of the area. Thus, the topsoil layer is fairly thin – on the average. And, the horizons – being young – less than 10 thousand years old – are not well defined. Their intersections are a bit blurred.
Some southern areas in the Mid-Atlantic region were vacated by the glaciers a few thousand years earlier and their horizons are more defined.
There are only 3 states in this region – New Jersey, New York, and Pennsylvania – making it easy to browse them one at a time – or, jump to the state of most interest.
New Jersey (NJ)
New Jersey’s state soil, Downer, is a yellowish, sandy soil that covers over 290,000 acres throughout the state – with the most dominant concentrations in 11 counties of southern New Jersey – especially in the Pine Barrens area. It was developed from acid, loamy Coastal Plain sediments.
The level of natural fertility is “medium” – which means that additional fertilization is necessary for optimum crop growth.
Beneath the partially decomposed organic matter – or, “O” horizon – the topsoil – or, “A” horizon – is dark, grayish brown loamy sand. The “A” and “O” horizons together have an average depth of 11 inches.
The “B” horizon – or, subsoil – changes gradually from grayish brown sandy loam to yellowish brown coarse sand. Average thickness is 30 inches.
Because of the strong acidic nature of this soil, lime is added to reduce the acidity. Both lime and fertilizer may also need to be added periodically throughout the growing season because the sandy soils easily leach the amendments from the top layers – forcing them down into the subsurface layers.
Also, because of the higher than normal leaching, the soil will dry out more quickly – making irrigation a necessity – and soaker hoses are the most appropriate method to produce an adequate supply of water to the plants.
Keep in mind that, even with its limitations, Downer soil grows some of the most outstanding fruits and vegetables you can get! This is good news for the backyard gardener!
New York (NY)
Honeoye (Hay- ĕ – ă -yeah’) soil covers a half million acres in the great state of New York. This soil mostly occurs in an area spanning central and western New York and can be found in at least 15 counties. Honeoye soil began forming once the glaciers receded during the ice age – about 12,000 years ago.
The name, “Honeoye”, is from the Seneca Indian language – and there is a tale about a Seneca Indian’s finger being bitten by a rattlesnake. In order to prevent the venom from spreading to the rest of his body, the Indian cut off his finger. “Honeoye” means “the place where the finger lies.”
These highly rich soils produce a wide range of vegetables – along with various pasture grasses (alfalfa, hay, wheat, oats, etc.) – and numerous grape and apple orchards.
Honeoye soil is very fertile – though, a bit acidic in the top layers. It approaches “pH neutral” further down in the subsoil layers.
Dark, grayish brown loam is found in the “A” horizon. This layer contains a lot of silt loam – but, not much clay.
Below that, the soil layers in the “B” horizon go from a brown loam to a dark, grayish brown gravelly loam to a dark, grayish brown VERY gravelly loam – and, there are many more clay particles here than there are in the “A” horizon.
This soil is very deep and well drained – and a superior medium for veggie and fruit crops – as well as vineyards and orchards. Due to the prolific grape, cherry, and apple crops in New York, this state is home to over 95 wineries.
Soil erosion is a serious factor in New York. Thus, during the off season months, many gardeners opt to plant cover crops to protect their soil from washing away and to add valuable nutrients to the soil in preparation for spring planting.
Hazelton soil, the state soil of Pennsylvania, is named for the city – in east central PA. Occurring in over half the counties in the state, Hazleton soil covers more than 1.5 million acres of land.
Though other soils were considered for the title of “state soil” – such as Berks, Gilpin, and Penn – Hazleton soil won the most votes because it is the most plentiful.
The “O” and “A” horizons reveal dark brown, stony and sandy loam soil – while the lower levels change from dark gray stony sandy loam – “B” horizon – to light yellowish brown very stony and sandy loam – “C” horizon – to gray sandstone, along with red, gray, and brown shale in the bedrock – or, “R” horizon.
This naturally fertile soil runs deep – or, very deep – and, is exceptionally well-drained.
The downside is that water drains so quickly through the soil layers that the soil is constantly in danger of drying out too rapidly. Thus, irrigation, preferably in the form of soaker hoses, is a good idea to maximize harvests for any fruits and vegetables that the backyard gardener wants to grow.
Being slightly acidic, the pH may need to be tweaked with a little lime at the beginning of each growing season. And, the standard fertilizers – 10-10-10 – and, 0-0-60 – can normally be used to feed the crops.
