Navigate parenthood with the help of the Raising Curious Learners podcast. In the present novel review, we discuss the peat use in horticulture. Peat may be distinguished from lower-ranked coals on the basis of four characteristics: peats generally contain free cellulose, more than 75 percent moisture, and less than 60 percent carbon, and they can be cut with a knife. https://www.britannica.com/technology/peat, National Geographic - Education - Peat: The Forgotten Fossil Fuel, Food and Agriculture Organization of the United Nations - Energy Use of Peat, peatland - Children's Encyclopedia (Ages 8-11), peat - Student Encyclopedia (Ages 11 and up), Intergovernmental Panel on Climate Change. Peat has important functions for plant. The usage ratios of peat by country are as follows: 99% in Estonia, 99% in Lithuania, 92% in Latvia, 88% in Finland, 87% in Ireland, 87% in Denmark, 87% in Sweden, and 81% in Germany [50]. Read more about working with peat soil at blooms4all.com The comfort of the usage of rock wool cubes and slabs provides producing private mixtures with better properties for plant species between the 1980s and 1990s. For plants that like a more alkaline soil, compost may be a better choice. Peat bog near Enschede, Overijssel province, Netherlands. The peat becomes the main component for containerized mixture in commercial production and also very good component for vegetable and ornamental growing media when compared with all other organic materials for horticultural crops due to its several physical properties like high porosity and water holding capacity (WHC), slow degradation ratio, and low bulk density, and also good chemical properties like high cation exchange capacity (CEC) [23]. Dry, sandy soils benefit from adding peat moss to retain moisture, and peat moss improves drainage and prevents compaction in dry and wet soils … Container-grown plant substrate mixtures are very important for the production of nursery and greenhouse plants. Due to low quality of products, the numbers of customers of Allagnou’s were declined and the factory was closed. Hemicellulose has between 200 and 300 sugar units which compose long chains of glucose, fructose, mannose, galactose, rhamnose, arabinose, xylose, galacturonic acid, and glucuronic acid. Smaller amounts of peat are also used for soft fruit and cut flower production. Peats may be divided into several types, including fibric, coarse hemic, hemic, fine hemic, and sapric, based on their macroscopic, microscopic, and chemical characteristics. We are IntechOpen, the world's leading publisher of Open Access books. Peat, fuel consisting of spongy material formed by the partial decomposition of organic matter, primarily plant material, in wetlands such as swamps, muskegs, bogs, fens, and moors. Allagnou from France was founded a factory to produce fibers from peat in 1884. Use two parts soil to one part peat moss and mix it. Some gardeners even add peat moss to their compost as a carbon source, as well as a bulking agent. Let us know if you have suggestions to improve this article (requires login). Chitin is a linear polymer of N-acetylglucosamine and is determined in the cell walls of fungi as shown below in Figure 3. Some of peat alternatives may include wood residues, forest harvest materials, urban wastes, composts, and other industrial wastes. For example, thick, clay-like soil can be mixed with peat moss to lighten it and give it a more fluffy texture. There, after slight maceration, it is pumped to a draining ground in a layer, which, after partial drying, is cut up and dried further. Next form of peat in industry was active carbon which is sourced by black peat. With the increasing amount of soilless cultures in the world in the last years, the general forms of peats were started to use as peat-lite and bark and wood chips mixture for growing media in the container systems [1]. As peat moss is sterile, its presence in soils can help minimize disease issues. Organic Com-Peat soil can be used in gardens, lawns, orchards and in all types of tree plantings, both fruit trees and ornamentals. Government has set as target that 40% of the total market demands, for growing substrates and soil improvements, should not be covered with peat-reduced or peat-free products, by 2004. Adding peat … Virtually all rural households are now connected to the national electricity network, which relies partly on hydroelectric plants and on small and medium-sized peat-burning thermal power stations. Precisely the reason why peaty soils have much more organic content than other types of soil. Different media are used in plant cultivation. There are significant differences between sphagnum moss and peat moss due to sphagnum moss’s live portion or young residue of the plant. Uses for BONAPARTE PEAT SOIL. Peat moss is organic matter that contains decomposed plants--often sphagnum moss. Recently, peat has been used for electricity generation in small units in the range of 20-1 000 kW. Due to this system, horticultural plants are increased by yield in soilless culture compared to culture of conventional soil. This medium allows for the optimal development of plants in pot [16, 17, 18]. With increasing depth of burial and increasing temperature, peat deposits are gradually changed to lignite. It can pick up various chemicals such as nutrients and pollutants. Alternative substrates such as paper and timber waste, bark, and wood fires have a high percentage of cellulose and hemicellulose. It composes from accumulation of nutrient and oxygen imperfection, acidity and waterlogging conditions. In the recent decades, the decreasing usage of peats brought the ascending prices and costs and also produced some hesitations if it will have an impact on environmental problems. It is also added to potting mixes to meet the acidity requirements of certain potted plants. The total porosity in the peat reaches up to 80–90% and even a bit more due to dominantly low bulk density values despite less particle density. When dry, the blocks weigh from 0.34 to 0.91 kg (0.75 to 2 pounds). This is about double the price of flexible plugs, and close to triple the price for starting seeds in soil. Dried peat burns readily with a smoky flame and a characteristic odour. In the horticulture industry, the peat has three different forms that are commonly used as peat humus, moss peat, and reed-sedge. By resisting compaction, it ventilates oxygen deep into the soil bed, this phenomenon is commonly referred to as Aeration. Peat is usually hand-cut, although progress has been made in the excavation and spreading of peat by mechanical methods. Bogs are a type of wetland with a high acid content. Many peat bogs are characterized as special areas of conservation. "While oil, coal, and natural gas are exported around the world, few outside northern Europe are aware of this energy source. It is slight, clean, sterile, and does not include foreign material. 3. The decomposition degree effects the proportion of lignin in an ascending way about the decay resistance of lignin. The oxygen decrease in peat leads to 10% decrease via ascending humification approximately 43% at H1–H3 and 33% at H8–H10. Given that peat harvesting is destructive to wetland habitats, its use as a soil amendment has been discouraged by conservationists. Between the several organic matters which are used as substrate for horticultural plants cultivation in soilless conditions, peat is the unabandonable ingredient for mixtures for commercial production of plants. It keeps water and nutrients, and gives them steadily to plants. The results of many studies showed that peat provided high macropore volumes (45–50%) and also greater water volumes (40–45%) at low tensions (<1 kPa) [31, 32, 33, 34]. Nurgul Kitir, Ertan Yildirim, Üstün Şahin, Metin Turan, Melek Ekinci, Selda Ors, Raziye Kul, Hüsnü Ünlü and Halime Ünlü (November 5th 2018). How? Humic acids and bitumen ratios are increasing as seen in Table 2. The positive effect of the physical properties in peat medium is the continued long period. In general, approximately 80–90% of a fresh peat sample is composed of water and the remaining of solid material. The common media used for the systems in Northwest Europe and Israel are peat [2, 3]. We share our knowledge and peer-reveiwed research papers with libraries, scientific and engineering societies, and also work with corporate R&D departments and government entities. Brief introduction to this section that descibes Open Access especially from an IntechOpen perspective, Want to get in touch? In the US, the optimum soilless component was determined as bark and peat for crops growing in short or long periods in 1950s [12]. During the last years, there has been an increased concern about the use of peat. Some supermarkets have given instructions to the growers that in order to keep buying from them, they should limit the use of peat. Soil Amendment: If you wish to use peat moss as a soil amendment, it’s best to apply it in a 2:1 ratio. In certain circumstances, peat can be an early stage in coal formation. The use of peat for agriculture and horticulture is determined by the following quality parameters: the degree of decomposition, ash content, pH, the presence of carbonates, the density of the solid phase, bulk density, and porosity. The total porosity of a growth media is the sum of the macro-, meso-, micro-, and spaces of ultramicropores [31]. Particle density is relatively low, usually ranging from 1.0 to 1.6 [29]. Licensee IntechOpen. In the EU, the reported total amount and ratio of peat in media for plant growth is 25,990,000 m3 equaling 75.1%. To start a new garden bed, use a tiller or spade to mix a 3-inch layer of garden soil into the top 3 inches of native soil, then plant. Peat Use in Horticulture, Peat, Bülent Topcuoğlu and Metin Turan, IntechOpen, DOI: 10.5772/intechopen.79171. Peat stimulates plant growth and root development by improving the structure of the growing media. Get exclusive access to content from our 1768 First Edition with your subscription. Login to your personal dashboard for more detailed statistics on your publications. To date our community has made over 100 million downloads. In plant shipment, to line hanging baskets, and in propagation, the most used matter is sphagnum and there are some efficient substances in sphagnum to inhibit the fungi growth related with damping off. North Country Distributors is the exclusive provider of Bonaparte Peat (hypnum peat), with its higher level of organic matter and high microbial diversity. An experiment which took place in Nottingham Trend University investigated changes in organic growing media during storage [24]. A mixture called “John Innes” includes some blends of loam, sand, and peat. It is the precursor material from which coals are derived, and the process by which peat is formed is studied in existing swamps in many parts of the…, For centuries hand-cut peat, or turf, was the rural population’s principal domestic fuel. Scientists all over the world examine the potential peat alternative substrates and the disadvantages that may have, when compared to peat. Pick out the trash, sift it, or if there is too much trash use that bale in your garden and try … Maceration tends to yield more uniform shrinkage and a denser and tougher fuel. Articles from Britannica Encyclopedias for elementary and high school students. Hemicelluloses are composing the biggest part of peat. Peat worked into the soil probably won’t offer too much protection from splashing, though it can certainly make the soil a bit more absorbant and springy. Because of the several disadvantages, the use of peat alternatives is going to expand in many different horticultural sectors. Peat is one of the most important growing medium that is safe and cost-effective used in the production of horticulture plants. The main part of the structure of lignin is shown below in Figure 4 and called as phenol, composed a chain of n-propyl in para position and a group of methoxyl in one or two ortho positions. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. As PhD students, we found it difficult to access the research we needed, so we decided to create a new Open Access publisher that levels the playing field for scientists across the world. Hydraulic excavating can also be used, particularly in bogs that contain roots and tree trunks. Peat moss will lighten up the soil in your garden, which may have become compacted over the years, resulting in inadequate drainage. In 1999, 36% of the market was covered by peat alternatives. It is a perfect growth substrate for greenhouse crops, trees or vegetable seedlings, and potted ornamental plants. To gain much quality and more productivity in crops, ornamental and greenhouse plants, peat is used for a fast production. The destiny of the nursery and greenhouse production is related with the growing media quality. Scientists have made several experiments to test peat alternative substrates [1]. In the history, there are two production types in peat factories such as peat cardboard and clothing. Peat moss (Sphagnum) is one of the most common constituents of peat. Peat moss is an important component of most potting soils an… Use garden soil outdoors, in the ground. For a long time, peat has been used for as absorbing urine in stables or as a great and dirty fuel. In addition to this, peat moss does not comprise weed seeds or … It can be used as a very good heat insulator for dry peat. Lawrence and Newell were the creators of standardized growing media for commercial purpose in 1930, UK [2]. Added to clay soils, it provides air in the dense soil, allowing rose roots to absorb needed oxygen. By making research easy to access, and puts the academic needs of the researchers before the business interests of publishers. Peat is soft and easily compressed. Peat has been used for successful cultivation of different vegetables and ornamental crops in soilless culture since the early 1900s. Although the humification level is not effective, the derived plant matter from peat has some effects on chemical property. Plant material decomposes more rapidly in groundwater rich in nutrients than in elevated bogs with heavy rainfall. It is also often used as an ingredient in planting mixes and potting soils. It has an important structural characteristic that is long constant even under intensive use and it is biodegradable [6]. Also, it can improve garden soils [7]. When a comparison was made between only-peat substrate and peat-perlite and peat-zeolite substrates, the biggest leaf area was determined in seedling growth in only-peat substrate; however, the dry material content was not much in leaves when compared with the peat-perlite and peat-zeolite substrates [1]. Many different mediums and mixtures of them have been used in growing seedlings in recent years, especially peat. So the intensive use of peat in horticulture industry may cause the release of CO2 from these ecosystems as it is a nonrenewable source. The solid material has most of the components as organic and only 2–10% as inorganic. Additionally, there are several types of peat from bog to bog. When we look at the historical dimension of growing media development, as an example, in Germany, it has been used in many different steps like below. It is both sterile and free of weed seeds. The physical properties of peat include total porosity, pore sizes, water retention, bulk density, etc. Omissions? Although peat is not strictly a fossil fuel, its greenhouse gas emissions are comparable to that of fossil fuels. For all these reasons, it is necessary to pay attention to the selection of the environment to grow seedlings. In the production of media for plant growth, there have been used several combinations of inorganic and organic components. Due to this, global warming may increase and a global movement should be started to success a sustainable peat and an intelligent wetland usage. There have been several studies conducted on pepper growth with soilless substrate on the parameters such as growth, quality, and quantity after studies on tomato. According to data, peat use by sector in UK is 32% for container nursery stock (280,000 m3), mushrooms 30% (260,000 m3) bedding plants 16% (143,000 m3) and other sectors such as pot plants, vegetable transplants, glasshouse salads, and bulbs follow. Mediums are used for seedling growing, seed germination, emergence rate, rate of growth, and quality of the seedlings. The water in the ultramicropores with less than 3 μm diameter is not useful for plants. The most common applied method is the use of transplants in small cell production using peat-based media [43]. In precious crop production, soilless culture systems in greenhouses are advised as alternative system to conventional production. The use of peat alternatives is going to expand in many different horticultural sectors. The medium in which seedlings are growing is important in healthy and high-quality seedling production. Finally, further research could be done so as to determine the optimum substrate for each plant. There are many uses of peat moss, such as improving soil, starting seeds, adding it as an amendment, and more. The development of peat is favoured by warm moist climatic conditions; however, peat can develop even in cold regions such as Siberia, Canada, and Scandinavia. In the process of humification, the degradation occurs, and it is not only loss of matters. Peat moss as a soil amendment is known to improve the quality of the soil. The difference between peat moss and the compost, Peat moss is sterile, contains only a few microorganisms, has acidic pH values, prevents soil compaction and improves moisture retaining. It can also be used as a mulch around garden plants to help the soil retain moisture and prevent weed growth. Water and nutrient retention: peat moss has the ability to hold water well. The microbial degradation of vegetative material in peat leads to 10% increase in the carbon content of peat from 50% at H1–H3 to 60% at H8–H10. The elemental composition of peat change is given in table below as decomposition function. In the highly decomposed peats, the microorganisms in the soil degrade the materials into hemicellulose and cellulose. In general for the greenhouse plants, this system is used to maximize the productivity of crops and utilizing from all inputs in an efficient way for commercial production. In a media, high ratio retention of easily available water and providing good aeration for respiration of roots are considered the most important physical properties that needed to promote optimal plant and seedling growth. Also, in the plants with the bare roots or ball rooted plants, the mixtures were commonly used. Instead of this, the organic matter is laid down and accumulates in a slow time as peat due to the oxygen deficiency in the bog. In order to further decrease the peat in horticulture, further research is required for disease, nutrition and water management, and storage characteristics. This is also a common process in production of peat which has started in the late 1890s. If your soil is dry and crumbly, mixing some peat moss in with it will help it hold its shape and retain moisture. The peat also enables the media for several applications with its low pH and nutrient content.
