A sapric is a subtype of a histosol [1] where virtually all of the organic material has undergone sufficient decomposition to prevent the identification of plant parts and even fecal matter. [2] [3] Muck is a sapric soil that is naturally waterlogged or is artificially drained.
The soils are deep, dark colored, and friable, often underlain by marl, or marly clay.[ citation needed ]
The World Reference Base for Soil Resources (WRB) defines "sapric" (sa) as a histosol having less than one-sixth (by volume) of the organic material consisting of recognizable plant tissue within 100 cm of the soil surface. [4]
Muck soils fall under the Organic Order in the Canadian system of soil classification. [5] Muck soils are organic soils, with at minimum of 30% organic matter and a depth of at least 40 cm. [5]
In the USDA soil taxonomy, sapric may be a subtype of a haplohemist or glacistel type, and may also be a diagnostic organic soil material where the fiber content is less than one-sixth of the volume. [2] Muck soils are defined by the USDA NRCS as sapric organic soils that are saturated more than 30 cumulative days in normal years or are artificially drained. [6] An example would be a soil made up primarily of humus from drained swampland.[ citation needed ]

Muck farming on drained swamps is an important part of agriculture in New York, Ohio, Illinois, Indiana, Michigan, Wisconsin, and Florida, where mostly vegetables are grown. The muckland of Torrey Farms of Elba, New York, which covers the counties of Orleans, Niagara, and Genesee, is thought to be the largest continuous section of muckland in the world. [7] Another large tract of muckland, known as the Black Dirt Region, exists in the lower Hudson Valley. American "muckers" often have roots from the Netherlands or Eastern Europe, where their ancestors practiced a similar type of farming. Holland Marsh, north of Toronto, Ontario, is the site of the Muck Crops Research Station, a University of Guelph facility.[ citation needed ]
Muck farming is controversial because the drainage of wetlands destroys wildlife habitats and results in a variety of environmental problems. It is unlikely that any more will be created in the United States because of environmental regulations. It is prone to problems. The soil is very light, so windbreaks are necessary to protect these fields in dry weather. It also can catch fire and burn underground for months. Oxidation also removes a portion of the soil each year, making it progressively shallower. Oxidation also discharges carbon dioxide. Some muck land has been reclaimed and restored as wetlands for wildlife preserves.[ citation needed ]
The impacts of drainage and agricultural production cause the loss of organic matter in muck soils through erosion, oxidation, and other processes collectively called "subsidence." Agricultural practices such as cover cropping and reduced tillage can significantly reduce subsidence but can not reverse it. Muck soils are, in essence, a non-renewable agricultural resource. [8]
The word muck has much usage in the English language, referring in some cases to agricultural soil, and in others to dirt in general, and animal dung (sometimes human feces) in particular. Origins are probably from Norse, Danish, and Proto-Germanic roots referring to cow dung. [9] [10]
Oxisols are a soil order in USDA soil taxonomy, best known for their occurrence in tropical rain forest within 25 degrees north and south of the Equator. In the World Reference Base for Soil Resources (WRB), they belong mainly to the ferralsols, but some are plinthosols or nitisols. Some oxisols have been previously classified as laterite soils.
Chernozem, also called black soil, regur soil or black cotton soil, is a black-colored soil containing a high percentage of humus and high percentages of phosphorus and ammonia compounds. Chernozem is very fertile soil and can produce high agricultural yields with its high moisture-storage capacity. Chernozems are a Reference Soil Group of the World Reference Base for Soil Resources (WRB).
Natural Resources Conservation Service (NRCS), formerly known as the Soil Conservation Service (SCS), is an agency of the United States Department of Agriculture (USDA) that provides technical assistance to farmers and other private landowners and managers.
Soil classification deals with the systematic categorization of soils based on distinguishing characteristics as well as criteria that dictate choices in use.
In soil science, podzols, also known as podosols, spodosols, or espodossolos, are the typical soils of coniferous or boreal forests and also the typical soils of eucalypt forests and heathlands in southern Australia. In Western Europe, podzols develop on heathland, which is often a construct of human interference through grazing and burning. In some British moorlands with podzolic soils, cambisols are preserved under Bronze Age barrows.
Gelisols are an order in USDA soil taxonomy. They are soils of very cold climates which are defined as containing permafrost within two meters of the soil surface. The word "Gelisol" comes from the Latin gelare meaning "to freeze", a reference to the process of cryoturbation that occurs from the alternating thawing and freezing characteristic of Gelisols.
A vertisol is a Soil Order in the USDA soil taxonomy and a Reference Soil Group in the World Reference Base for Soil Resources (WRB). It is also defined in many other soil classification systems. In the Australian Soil Classification it is called vertosol. The natural vegetation of vertisols is grassland, savanna, or grassy woodland. The heavy texture and unstable behaviour of the soil makes it difficult for many tree species to grow, and forest is uncommon.
In both the World Reference Base for Soil Resources (WRB) and the USDA soil taxonomy, a Histosol is a soil consisting primarily of organic materials. They are defined as having 40 centimetres (16 in) or more of organic soil material starting within 40 cm from the soil surface. In Soil Taxonomy, Gelisols key out before Histosols, and in WRB, Histosols key out before Cryosols. Therefore, organic permafrost soils belong to the Histosols in WRB and to the Gelisols (Histels) in Soil Taxonomy.
Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations like milk and egg production. It may be performed in plants using mechanized treatment units similar to those used for industrial wastewater. Where land is available for ponds, settling basins and facultative lagoons may have lower operational costs for seasonal use conditions from breeding or harvest cycles. Animal slurries are usually treated by containment in anaerobic lagoons before disposal by spray or trickle application to grassland. Constructed wetlands are sometimes used to facilitate treatment of animal wastes.
The World Reference Base for Soil Resources (WRB) is an international soil classification system for naming soils and creating legends for soil maps. The currently valid version is the fourth edition 2022. It is edited by a working group of the International Union of Soil Sciences (IUSS).
The Holland Marsh is a wetland and agricultural area in Ontario, Canada, about 50 kilometres (31 mi) north of Toronto. It lies entirely within the valley of the Holland River, stretching from the northern edge of the Oak Ridges Moraine near Schomberg to the river mouth at Cook's Bay, Lake Simcoe. In its entirety it comprises about 21,000 acres, with two distinct divisions. Historically it has simply been referred to as "the marsh".
In soil classification, an Umbrisol is a soil with a dark topsoil and in which organic matter has accumulated within the mineral surface soil—in most cases with low base saturation—to the extent that it significantly affects the behaviour and utilization of the soil. Umbrisols are the counterpart of comparable soils with a high base saturation.

A gleysol or gley soil is a hydric soil that unless drained is saturated with groundwater for long enough to develop a characteristic gleyic colour pattern. The pattern is essentially made up of reddish, brownish, or yellowish colours at surfaces of soil particles and/or in the upper soil horizons mixed with greyish/blueish colours inside the peds and/or deeper in the soil. Gleysols are also known as Gleyzems, meadow soils, Aqu-suborders of Entisols, Inceptisols and Mollisols, or as groundwater soils and hydro-morphic soils.
Hydric soil is soil which is permanently or seasonally saturated by water, resulting in anaerobic conditions, as found in wetlands.
G. Wade Hurt was a soil scientist in the United States and an authority on hydric soils. As of 2007, he was a position with the University of Florida's Soil and Water Science Department in Gainesville.
A Stagnosol in the World Reference Base for Soil Resources (WRB) is soil with strong mottling of the soil profile due to redox processes caused by stagnating surface water.
Andosols are soils found in volcanic areas formed in volcanic tephra. In some cases Andosols can also be found outside active volcanic areas. Andosols cover an estimated 1–2% of Earth's ice-free land surface. Andosols are a Reference Soil Group of the World Reference Base for Soil Resources (WRB). They are closely related to other types of soils such as Vitrosols, Vitrandosols, Vitrons and Pumice Soils that are used in different soil classification systems. The name comes from Japanese an and do, synonymous with kuroboku. In the USDA soil taxonomy (ST), many Andosols belong to the order of the Andisols. However, the definitions are different. Some Histosols (WRB) belong to the Andisols (ST), and some Andosols (WRB) belong to the Inceptisols (ST).
Torrey Farms is a large family farm located in Elba, New York, with a satellite property located in Potter, New York. It is one of the largest vegetable-crop farm operations in New York. Together its two lots total some 10,000 acres, composed primarily of muckland, in the instance drained swampland.
