Eucalyptus is a genus of over 700 species of flowering trees and shrubs . Originally native to Australia , these fast - growing trees are now tame worldwide , from California to the Mediterranean However , eucalyptus has develop a repute for damaging soil quality and hinder the growth of other plants So is eucalyptus really bad for dirt ? Let ’s take a close look at the evidence .
How Eucalyptus Can Harm Soil
There are a few key ways that eucalypt can degrade soil wellness
Allelopathy
Many eucalyptus tree species exhibit a phenomenon call allelopathy . This think they release chemical compound that suppress the growth of other plants in the surrounding soil .
The independent allelopathic compound in eucalyptus are phenolic pane As the parting and barque of the tree break down , these phenolic acids leach into the grime They can then inhibit come sprouting and root emergence of nearby plants . This gives eucalyptus a competitory boundary , while subjugate biodiversity .
subject area have establish reduced ontogenesis in vegetables , herbs , lettuce , and citrus trees planted in territory containing eucalyptus tree leafage matter . So allelopathy can right away harm crop fruit and grunge productivity .
Water Hogging
Eucalyptus tree are hungry behemoth . Their recollective taproot can accomplish down over 30 metrical unit to access groundwater . And grownup Sir Herbert Beerbohm Tree can transpire over 300 gallons of body of water per daylight !
This aggressive water expenditure depletes ground moisture . Dry soils become crack and compacted . Important grunge bug are harm . Nutrient cycling and organic matter decomposition dumb down .
Eucalyptus plantations have been blame for lowering water table and dry out up springs and stream in place like California . Their body of water hogging way directly mar soil wellness .
Nutrient Imbalances
The debris from eucalyptus leaf and bark decomposes slowly . This results in a buildup of constitutional matter on the soil surface .
However , this organic matter has a high carbon paper to nitrogen ratio . So as it decompose , soil microbes will rob the surrounding land of nitrogen . Thisnutrient dissymmetry can reduce birthrate and inhibit plant growth .
The Benefits of Eucalyptus Trees
However , eucalypt trees are n’t all bad intelligence for land . They can also provide some benefits :
Erosion Control – The dense canopy and leaf litter helps verify runoff and forestall soil erosion .
Organic Matter – As leaves and barque slowly erupt down , they do total organic cloth to the filth . This can improve piddle holding , cation exchange capacitance , and nutrient cycling .
Mulch – Eucalyptus leaves or barque make excellent mulch for water conservation and weed quelling .
Windbreak – These tight - turn trees can bring home the bacon shelter from drying wind when used as windbreaks .
So in certain contexts , eucalyptus trees can enrich soils . But care should be taken to balance their land benefits with their potential for harm .
Sustainable Management Practices
If you need to grow eucalypt trees , but avoid demean your dirt , here are some tips :
Space Sir Herbert Beerbohm Tree wide apart to reduce competition . go out at least 30 - 50 foot between Tree , calculate on species .
Remove folio litter before it build up up and use it for mulch or compost . Do n’t let it accumulate thickly under tree .
Test soil under trees p.a. and meliorate accordingly to maintain alimental symmetry .
Rotate eucalypt grove with other crops . Do n’t works eucalyptus tree monoculture .
Prune trees to concentrate weewee needs and allelopathic bedding material . Coppicing on short rotations can help .
Mulch around trees with wood chip or get to thin grime compaction and erosion .
Plant eucalyptus as windbreak , riparian buffers , and in urban areas – not directly in harvest playing field .
Choose less invasive eucalypt species like silver gray buck gumwood ( Eucalyptus cinerea ) or mealy stringybark ( E.muelleriana ) .
With some care and planning , you may minimize the soil wallop of eucalyptus tree Tree . But you ’ll need to actively manage plantations to foreclose foresightful - full term degradation .
The Verdict: It Depends
So is eucalypt flatly spoiled for territory ? The answer is n’t black and blank . Mature eucalyptus tree plantations can sure as shooting damage dirt ecology . But as part of a diverse landscape painting photomosaic , these useful Sir Herbert Beerbohm Tree can enrich dirt as well .
Before implant eucalyptus tree , analyze your landscape objectives and grunge pauperism . in good order spaced trees could hold in corrosion or provide shelter . But eucalyptus is unlikely to be suitable for intensive crop production . And secretive monitoring of ground health is essential .
Like any powerful peter , eucalyptus can be used constructively or destructively . With serious-minded design and care , your grunge can flourish alongside the elegant eucalyptus tree .
Group I: Bio-physical and Environmental Impacts of Eucalyptus Plantations
TOPICS IDENTIFIED FOR DISCUSSION
CONCLUSIONS ON BIO - PHYSICAL AND ENVIRONMENTAL IMPACTS
piss consumption
Eucalyptus is an effective biomass producer , it can produce more biomass than many other tree mintage . It also use less water per building block of biomass bring on than many other tree species . However , Eucalyptus species use more water supply than other , less fertile species because they turn quickly and produce a fortune of biomass . grow Eucalyptus in places with lilliputian rainwater may be unsound for the environment because it will compete with other plants for pee and cause more allelopathy . Because of this , areas that get less than 400 millimeter of pelting a year are usually not good for grow eucalyptus tree trees .
Soil Erosion
According to the information uncommitted , get Eucalyptus as such does not make soil erosion . Soil loss under Eucalyptus plantations has been reported within the satisfactory limit ( 12 . 6 tons / ha on a 40 % slope under 2,500 millimetre rain in West Java ) .
food pedal
When Eucalyptus is grow as a light - rotation harvest to make and polish off a destiny of biomass , the grime quickly loses its nutrient .
The leaves and bark of Eucalyptus Sir Herbert Beerbohm Tree contain a lot of nutrients . Leaving the leaf and bark on the logs after they have been contract down is a just management drill that will help keep enough food at the site .
Using unreal fertiliser is another room to bring nutrients to the ground , peculiarly for crops that are raise for a unforesightful time .
Allelopathic outcome ofEucalyptusis more prominent in country with low rain ( less than 400 millimetre each year )
Allelopathic essence may have implications when other species are grown near Eucalyptus trees . This is important peculiarly in agro - forestry organisation .
Biodiversity
The biodiversity of a natural forest and that of a Eucalyptus plantation are not comparable . The natural ecosystems are very various , whilst the biodiversity of Eucalyptus plantation is limited .
Pest and disease
Termite attacks are vernacular the Region . Susceptibility to this gadfly varies with the species . Some species such as E. camaldulensis and E. tereticornis are more susceptible than others .
Corticium salmonocolor“Pink disease ” is significant for some species in high rain areas in the Asia - Pacific Region .
Silviculture and Management
Most of the time , short rotations and intensive direction are used to get the most biomass out of the dry land . This can have regretful effects on the surround , like land compaction , soil erosion , alimentary export , pollution , and other bad effects from using fertilizer , weedicides , and pesticides , as well as fire chance .
Intensive management practice , which may create adverse environmental effects admit :
Tree procreation
Pests and diseases may round more often and need more inputs when high yield clonal varieties are bred , but this is not always the event . This is common with wish to most orchard metal money .
Effect on micro - climate
Not unparalleled toEucalyptus , effects on micro - climate conditions include lour of the temperature , CO2 arrested development , shading etc .

Agroforestry system with Eucalyptus and maize , Royal Forestry Department plantation , Thailand
Group II: Social and Economic Impacts of Eucalyptus Plantations – A Review of Country Situations and their Implications
Once you look at how things are in different countries , you could see that planting eucalyptus tree diagram is usually hunky-dory from a social period of persuasion . It is also accept that its planting is economically workable . multitude have said that planting eucalyptus has unfit effect on gild when it happens on public land that peasants live on and when lifelike woodland are make out down to make room for grove that foregather the need of clientele . In the past , this has also befall when eucalypt tree diagram were engraft in public areas that were once used to meet the indigence of livestock , or when people who depend on the region were not consult . In some situations , like with social forestry program , it was a mistake not to think about how market forcefulness might affect the labor . This put the goals of the project at risk .
plantation of eucalypt trees have helped rural people by providing them with firewood and small pieces of Ellen Price Wood that they would have to get from natural forests . This has slow down the charge per unit at which natural woodland are being cut down . This has also made it easier for woman to collect fuel , which used to take a huge amount of study .
Planting eucalyptus has help many pitiful farmers who know on res publica that is n’t good for farming get through tough economical times . In many developing countries , this mean that private planting covers a lot more land than planting by the politics or byplay .
When planted on Edwin Herbert Land that is n’t used for husbandry , eucalyptus tree plantations help create problem in both the planting and the processing of the trees .
Farmers who want to establish Eucalyptus trees are have difficulty because of fictive information about them , especially among city elite group and some NGOs .
In many countries , regulating deterrence imposed by the political science restrict the planting of fast growing tree let in eucalypts . In some of these countries a relaxation of these restriction has result in large scale plantings of eucalypts . Meeting the raw material needs of forest industries with Eucalyptus wood should not be disregarded .
little farmers in some nation are faced by merchandising trouble when they attempt to sell their products . They are also exploited by middlemen and industries .
REMEDIAL answer
In places where turn land that used to be used for agriculture into eucalypt plantations has made it harder to find work , intensive land methods that create jobs and work in more money may be pushed .
Many of the social issues associate with Eucalyptus spp . plants were plant on public or communal land without asking the masses what they thought should be done first . It is important to give extra aid to the needs of landless people who used to be able to freely access these situation to get wood and other supply but ca n’t because of the orchard course of study . provide a interest in such plantation to these people will deoxidise social conflicts .
When subsistence farmers traverse into government activity land , the landed estate may be given to the occupants with the term that they practise agroforestry or tree diagram land rather of being squeeze to leave behind and eucalyptus tree are planted for industrial manipulation . Eucalypt land to produce assorted terminal products assure better comeback , particularly to pocket-size granger in break country .
In is preferable to use indigenous species if these serve the same objective lens as well as the exotics . Their acceptableness is ordinarily well .
It ’s important to demand that full befoulment control measures be put in place in industries that use forests ; eucalyptus trees are often blamed .
Public estimation of orchard project proposed by the government , industries and company would be useful . This will help to reduce inequities .
There are a lot of disagreements about eucalyptus because a lot of data and information about all of their parts is not widely shared . Both the electropositive and the damaging ecological , economic and social aspects should be made widely known .
POTENTIALS AND THE NEED TO procure MAXIMUM RETURNS
Cutting down trees for fuel and moving crop around are two thing that immediately injure the environment in many arise nation . Large area of land that are n’t being used at all , like kingdom that has been worn down or has brackish or salty dirt , , are also found in many country of the Region . Planting the right form of eucalyptus trees will help doctor damaged solid ground , fulfill people ’s needs for biomass , and stop the loss of more Sir Herbert Beerbohm Tree in other place .
caliber planting cloth of eucalypts is lacking in most area . Private enterprise should be encouraged to create such cloth , particularly to meet the needs of Farmer .
There is n’t enough inquiry on Sir Herbert Beerbohm Tree breeding to make genetically improved , high-pitched - quality planting cloth that has a deal of potential drop for both industrial and non - industrial goods . This research should be promoted to amend the economics and to provide social benefit .
potential offer by eucalypts in the output of dearest , mushrooms and rock oil are not explored in many countries . This should be rectified .
BENEFITS TO LOCAL COMMUNITIES
It is easy to grow eucalyptus Sir Herbert Beerbohm Tree on damaged or miserable soils , and they grow quickly and can be cut down . This has been very helpful for rural communities in many modernise land where a slew of people practice firewood for fuel . In improver , lops and tops of eucalypt rise on public or private land have been a welcome source of fuel for the poor multitude . It is suggested that lops and tops , which make up about 25 % of the above - ground biomass , should be given to poor and landless masses in the community in the slip of government plantations .
DEVELOPMENT OF PROCESSING AND MARKETING
It can be hard to use new wood from some eucalypts as poles and lumber because of the problem that come with their fast growth charge per unit . Through research , many of these problems have now been solved , but the great unwashed still need to learn how to habituate the Modern technologies . This postulate urgent attention .
selling imperfections abet by restrictive government regulation pose problem in disposal of produce in some area . Such regulation should be remove to encourage tree diagram planting . imperfectness in the market can be fix by supporting monetary value , especially for little farmers , or by encouraging cooperative to betray their goodness at fairish terms .
