What is black peat used for?
Black peat is a very dense, fine particle peat moss that is highly decomposed. It is sometimes used for blocking substrates for starting vegetable seedlings, such as lettuce. It is usually blended with other types of peat depending on the type of crops grown.
What is the pH of black peat?
The black peat originates in low areas, with a high base content, so that its pH is much higher , typically between 7.5 and 8. They are peats in which organic matter is decomposed enough, so They are very poor in nutrients, but they are also ideal for the development of all types of plants if they are provided with the necessary nutrients.
What is the difference between white peat and black peat?
Black peat is decomposed more strongly than white peat. The most important plants for bog formation are sphagnum moss (Sphagnum spp.) and cotton grass (Eriophorum vaginatum) which makes up the fibers in the peat. Brown/black-colored black peat consists of the plant structure being largely decomposed.
How to distinguish between the two types of peat?
Depending on the area in which they are formed, we distinguish two types: Black peat (H7) : it forms in low areas, rich in bases. They are very decomposed, so their color is dark brown almost black. The pH is high, between 7.5 and 8. It has almost no nutrients.
What is the difference between black peat and white peat?
White peat is, like black peat, characterised by a low pH value of between around 3.0 and 4.0, as well as excellent water and air storage. White peat is one of the most important substrate constituents in commercial horticulture. Black peat is the deepest and oldest layer in peat bogs.
How is black peat formed?
Peat is a soft, crumbly, dark brown substance that is formed from generations of dead and partially decaying organic matter. To form peat, the vegetation must fall and be buried in a relatively oxygen poor environment so that it can be incorporated into layers of the soil without completely decomposing.
Why is peat harmful?
Peat releases huge amounts of stored carbon dioxide when it is harvested, which adds to greenhouse gas levels. Peat mining is effectively unsustainable – it grows back at just 1 mm a year.
What is peat used for?
Peat is used for domestic heating purposes as an alternative to firewood and forms a fuel suitable for boiler firing in either briquetted or pulverized form. Peat is also used for household cooking in some places and has been used to produce small amounts of electricity.
Why is peat so important?
Peat is hugely important to our planet for lots of reasons. It acts as a carbon store, it is a great habitat for wildlife, it has a role in water management, and preserves things well for archaeology.
Why do they burn peat?
Across the uplands of northern England, large areas of peatland habitats have been routinely and deliberately burnt, largely to support a single industry – grouse shooting. The reason they are burnt on shooting estates is to encourage the growth of young heather on which the red grouse feed.
Why gardeners should stop using peat?
Environmental leaders and other high-profile voices like Monty Don, the British horticulturist, author and broadcaster, have been sounding the cry: Gardeners should stop using peat, because the consequences of its continued harvest on diverse peatland habitats, and the native plants and animals that inhabit them, are ...
Which plants like peat soil?
Because of its low pH, peat moss is very suitable for vegetables and fruits that require an acidic environment. These include blueberries, pieris, heathers, azaleas, camellias, tomatoes, and so on.
What's the difference between peat and compost?
Peat moss and compost are not the same thing. Peat moss is a natural product that's formed as layers of moss grow over one another. (Peat moss is the bottom layer.) Compost is made as everyday waste materials decompose into nutrient-rich soil.

Is peat a coal?
The precursor to coal is peat. Peat is a soft, organic material consisting of partly decayed plant and mineral matter. When peat is placed under high pressure and heat, it undergoes physical and chemical changes (coalification) to become coal.
What is peat made of?
Peat forms when plant material does not fully decay in acidic and anaerobic conditions. It is composed mainly of wetland vegetation: principally bog plants including mosses, sedges, and shrubs. As it accumulates, the peat holds water. This slowly creates wetter conditions that allow the area of wetland to expand.
How is peat made?

As it accumulates, the peat holds water. This slowly creates wetter conditions that allow the area of wetland to expand.
Is black soil peat?
Black peat is the lowest quality peat. It contains no fibre and, unlike other peats, compacts readily and doesn't hold nutrients well. It needs to be amended with limestone for most garden uses, as its pH is much too low for most plants.
Is there black peat moss?
“Black peat” is a very dense, fine particle peat moss that is highly decomposed. It is sometimes used for blocking substrates for starting vegetable seedlings, such as lettuce.
What is peat dust?
Peat litter or peat dust is extracted from the top layer of the peat profile. The product is light brown and only slightly decomposed. Peat litter can retain at least 8 times its own weight in water. Water uptake and release is a slower process in this peat than in sphagnum moss peat.
What Is Peat
Peat is the substrate that is most used in the cultivation of all types of plants . It is economical, maintains humidity and is the most recommended soil for most of our pots. But did you know there are two types? Each one has its utility, as I will tell you next.
How is it formed?
Plants, as we know, have a limited life expectancy. As its leaves, flowers and stems dry, they fall to the ground, where a series of microorganisms such as fungi will decompose them.
What is it for?
Nowadays it is used to cultivate practically all types of plants: cactus , ferns , flowers, trees, etc.
Where does peat come from?
In the lowland humid tropics, peat is derived mostly from rain forest trees (leaves, branches, trunks and roots) under near constant annual high temperatures. In other geographical regions peat can be formed from other species of plants that are able to grow in water-saturated conditions.
What is peat in soil?
What is peat? Peat is the surface organic layer of a soil that consists of partially decomposed organic matter, derived mostly from plant material, which has accumulated under conditions of waterlogging, oxygen deficiency, high acidity and nutrient deficiency.
Is there a universal agreement on peat?
Definitions of peat vary across disciplines and between authorities for different purposes and there is no universal agreement that is applicable in all circumstances.
What are the different grades of peat?
Some of the common market grades include black peat, coarse/chunk peat, horticulture grade, fine, forestry and so forth.
What is peat humus used for?
It is popular with mushroom producers for mushroom casing mixes. It is also used as a soil conditioner for consumer products and sold as peat humus.
What is field grade peat moss?
Field grades of peat moss are screened, blended and processed to achieve specific physical properties for market grades and intended use. Market grades are based on coloration of the peat moss and the particle size passing through different mesh screen sizes (10, 20, 50 and 100 mesh screens).
Is sphagnum peat moss a grade?
It is peat that is screened from H1-H3 grades of fibrous peat moss and is free of sticks. Raw sphagnum peat moss is graded using the Von Post scale. In summary, sphagnum peat moss is suitable for a wide variety of growing needs. In determining the grade of peat moss to be used for the production of plants, a grower should select ...
Why are there different types of peat?
But there are various kinds of peat because the process is ongoing: part of the remains was “processed” and decomposed a long time ago, i.e. thousands of years ago, while the remains of the upper part are still in the process of “processing”.
What is the acidic peat used for?
When organizing planting sites or flower beds for such plants, it is the acidic permaculture peat that is used as one of the components of the soil mixture. In addition, the same acidic peat regularly covers these plants, supporting acidity at the right level.
WHEN DO YOU NEED PEAT?
And you shouldn’t expect peat to immediately increase soil fertility. In fact, peat does not contain many nutrients.
HOW MUCH PEAT SHOULD I PUT IN THE SOIL AND HOW SHOULD I PUT IT?
In principle, plants can be grown in pure peat as long as they are regularly fertilized. Incidentally, this is how plants are grown for sale in container production because the cost of transporting plants depends directly on the weight, and pure peat is much lighter than a fully nutritious soil mixture. But, again, this is only possible with conventional artificial plant nutrition.
What is the purpose of peat in a garden?
Therefore, the main function of peat as a fertilizer is to improve the quality of the soil itself, not its nutrition. In this case of peat fertilization, the roots of the plants are better able to extract all the necessary nutrients that are already present or that we make in the form of organic or mineral fertilizers. And this is probably the main characteristic of peat application in the garden.
How to use peat as a ground cover?
Therefore, in order to properly use peat as a ground cover, lay it on the surface during the wet season, and when the heat and drought begin – immediately dig it thoroughly over a depth of half a bayonet and mix peat and soil evenly. Only then can the peat function as a mulch.
What is the top layer of peat?
top layer of peat – “top” – poorly decomposed, in which there are strong physical and chemical transformations. It is distinguished by its high acidity (pH 2.5-3.2), fibrous structure, and low content of mineral elements.
What is block peat?
Block peat refers to the machine extraction of peat blocks by white peat cutting machines. The peat blocks or sods must dry in the field for at least one year in order to reduce the moisture content from 90 % to about 40-60 %. In the factory, the peat blocks are crushed and sieved into various fractions.
Is milled peat cheaper to harvest than block peat?
Although milled peat is cheaper to harvest than block peat, it generally has a larger amount of fine granulation.
