As companies that work in the food and agriculture manufacture , all of us like a shot take on the duty of see that we ’re leaving the food for thought system in a better state than it was before we entered it . In edict to do that , one of the things we need to do is make certain that we ’re inform about the abundant choice of agriculture input that are out there . Once we have a holistic idea of what exists , only then can the controlled environment agriculture ( CEA ) operator pick out the best option that aligns with their respective principles .
This week , we plunge into an factory farm resource that is more and more playing a greater role in agriculture as a grow media : peat .
What is peatPeat is made out of the dead , part decayed constitutional flora matter that accumulates in peatlands over many yr , millennia , in fact . The wet , acidic , downcast oxygen weather condition of peatlands slow down decomposition , trapping this organic topic . These peatlands get by close to 1 yard over 1,000 years . As you’re able to therefore imagine , re - growing peat takes a pregnant amount of time .
It ’s also important to love the difference between peat and peat moss . Peat is created from organic matter that is submerged in the bogs . Peat can be formed from different materials , but a bombastic percentage of the peat glean is indite of sphagnum moss , hence the name peat moss . Meanwhile , sphagnum moss is a plant life grown on the surface level above the peatland , filth , or swamp . It thrives in frigid and wet weather . As time goes by , the old voice sink into the crushed layer . The outgrowth of decomposition takes place very slowly in the oxygen - less level . Over a long period of metre , a duncish layer of dead material named peat moss is organize .
This telecasting by The unrecorded Streamed Classroom provides a clear reason of how peat is extract .
Where does peat come up fromAlmost all of the peat moss sell in the US comes from the vast sphagnum moss country in Canada . Even though Russia has the bombastic amounts of peatland around the world , Canada comes second in terms of the largest amount of spheric peat moss supply , with 25 % of the world ’s moss .
Nevertheless , at the moment , global communities are still trying to accumulate a vindicated mathematical function of where all of the peatlands sit . The most late and up - to - date map is The Global Peatland Map 2.0 , launched by the Global Peatlands Initiative partners at the Peatland Pavilion during UNFCCC COP26 . While it seeks to improve the baseborn noesis on the locating and extent of peatlands worldwide , decision makers still lack full insight on the extent of where peatlands are to prevent further drainage and abasement , which oftentimes comes from agriculture industries .
strength of peatPeat has a very good weewee - hold capacity . consort to Science Daily , peat moss can hold up to 25 times their dry system of weights in piddle , more than natural sponges . On the impudent side , even though it retains piddle very well , excess piss also quickly strike through the material to drain out , which means very fiddling water is stored in the metier , which could make a range of issue . look on the peat source , most peat moss have a pH in the range of 3.5 to 6 on median . For certain plants , having a growing media with a slightly acidic pH is a big advantage . Furthermore , it ’s fairly lightweight . Once harvest and dried , peat moss weighs approximately 25 lb per three-dimensional substructure , compared to the topsoil , which usually weigh about 40 lb per cubic foot .
In term of air circulation through the sensitive , after peat is dry out down to produce peat moss , it then does n’t compress very easily . Therefore , harvest grown with peat get access to a lot of open pore space within the material . From a nutrient perspective , it does have a high cation exchange electrical capacity . In other wrangle , it has many negatively charged sites that can hold onto positively charged speck such as nutrients and water . Lastly , peat moss is often used for seedling starting , in potting mixes , and even as a main hydroponic or aquaponic media .
ChallengesPeat is not always appropriate for all aquicultural system . Once it embark on to decompose , it compress around the roots , choking it in the anaerobic root zone . While some indoor farm will seek to balance this effect by adding more structure to the sensitive or to shuffle peat moss with something else , such as perlite or coco coir , it does signify that peat as a standalone ca n’t be as widely and easily used as some other grow mass medium . equate to other grow media , pure peat moss can be more expensive . It has low nourishing mental object due to the way that it ’s spring , namely the high water table and lack of nutrient that make its surrounding environment . Also , as bring up earlier , its slimly high-pitched pH degree makes it more acidic , which could be a problem for some indoor farms ' crops .
From an environmental perspective , the US Geologic Survey reports that " the loudness of globular peatlands has been diminish at a charge per unit of 0.05 % annually . " There are many other reasons to husband peat moss as well , the first and world-class being the massive habitat reducing that result from peat moss harvesting . Peatlands store twice as much carbon as all the world ’s forest . They ’re also a type of wetland that occurs in almost every country on the world , storing huge amounts of carbon . Unfortunately , when peatlands are farmed , it does the opposite , changing from being a carbon copy sink to a carbon emitter . About 15 % of the world ’s peatlands , which covers less than 0.4 % of the global demesne surface , have already been drain . Despite the minimal size , to show just how impactful peatlands are as carbon sinks , this 15 % removal has released huge amounts of greenhouse gases , such as carbon dioxide , from the carbon copy stored within peat soils into the atmosphere . GHG expelling from drain and burned peatlands equate to 10 % of all yearly fogy fuel emissions .
