Iron Bamboo Nurseries- Guroo Farms

Due to a proposed restriction on export of Shisham, we have, over the last 2 years, established an experimental Bambusetum, of about 8 bamboo species, including 2 of the rare Iron Bamboo varieties, namely, Dendrocalamus Stocksii and Thyrostachys Oliverii at Guroo Farms in the Terai Belt of Uttarakhand and Uttar Pradesh, India. Besides the afore-mentioned Iron Bamboos, we also have planted Nutaans and Balcooa, both being loosely clumped, thick walled and with straight growing habits.

Further, I would like to thank our Prime Minister, Mr. Modi to have taken the initiative of having Bamboo de-listed as a forest-produce, thereby facilitating ease of trade, and thus giving an impetus to bamboo agro forestry systems. We, as a Sovereign Nation have been sleeping over the error of classification which has resulted in bamboo not having been exploited to its optimum potential. Thus, China is way ahead of us, despite the fact that we, as a country, have a considerable bamboo stand in our forests, and also have agro-climatic zones that support bamboo agro-forestry systems. Botanically, bamboo is a grass and not a tree- an anomaly that should have been sorted out, way back.

I am trying to locate a reliable source of Guadua Bamboo, which is said to be an excellent species for Terai. It is one of the toughest TIMBER BAMBOO, ideal for construction.

My aim is to get about 10 to 15 acres under bamboo cultivation over the next 2 to 3 years.

Another issue that plagues my mind is the choice of the under-story crop for the first 2 years, till the bamboo stand establishes fully.

Does Turmeric fit the bill??

Iron Bamboo Sticks for Filipino Martial Arts

Silat, Kali, Arnis, Eskrima are variations of Stick Fighting Martial Art Form that evolved in Philippines.

Arnis & Eskrima are Spanish words. The term Escrima/ Eskrima, is derived from a Spanish term “esgrima”, meaning ‘fencing’. This art form was more from the central part of the Philippines. Arnis, is derived from a Spanish term  ‘Arnes de mano’ meaning ‘armour of the hands’. It was later shortened to ‘Arnis’. This art form comes from the northern parts of the Philippines. They're Filipino stick fighting mixed with European techniques of sword fighting

Kali is a Silat style, martial art form- and comes from the southern part of the Philippines. The word Kali is Indonesian, derived from the Bahasia dialect, meaning river. As per certain literature- the stick in Kali Stick Fighting, epitomizes the river, continuously flowing, unstoppable, with the ability to consume whatever lays in its path.  Throw a boulder in a river and the water will go under, over, through or around it but it will continue to flow.

For the most part, these are all similar, if not same, martial arts. The masters of these arts influenced each other and thus there are many similarities. The differences usually depend on the instructor.

IRON BAMBOO, is a rare variety of ALMOST FULLY SOLID BAMBOO SPECIES, harder than hardwood. Certain mechanical parameters are comparable to steel. Bamboo has a longer longitudinal fibre- thus does not break easily. It may momentarily yield/bend under extreme pressure, but comes back to its original form- much like an elastic. This helps to reduce the intensity of the impact shock.

Iron Bamboo Processing and Preservation

As a person undertaking agro-forestry of bamboo, we process Iron Bamboo for Handicrafts, Martial Art or Medieval Replica Weapons for Self Defense, which involves specialized methods and techniques of processing and preservation, to increase its durability.

Preservation techniques-

The empirical wisdom or popular knowledge, of indigenous people, peasants, farmers and artisans, has been developed through centuries in all the continents and has resulted in well-known methods and techniques to effectively preserve bamboo. Traditional methods are generally cheaper to implement and can be done without any special equipment.

For proper Preservation of iron bamboo, it must be harvested/cut early mornings, before sunrise, in winters - on a waning moon.** (This is a controversial topic, scientists argue over the truth behind this “peasant knowledge”. Nevertheless, detailed studies show remarkable differences with untreated bamboo, when harvested at specific hours and moon phases. The starch content is lowest between waning gibbous and last quarter between the 6th and 8th day after full moon due to the higher gravitation of the moon. On the basis of photosynthesis, in the course of the morning, bamboo starts transporting starch from the roots into the leaves.

Soaking- After harvest, bamboo is stored in running water for 3-4 weeks to leach out starch.

Chemical Treatments ( any one -to be done immediately after harvesting or after soaking)-

  • CCA (copper-chrome-arsenic composition, in the proportion 3: 1:4) is good for bamboo, but has associated health hazards. Thus, it has to be used judiciously, if at all. Bamboo products are tanalised, impregnated under pressure or boiled with chromated copper arsenate (CCA) to protect against rot. CCA is effective but toxic/carcinogenic.

  • ACA- Ammoniacal copper arsenate penetration in bamboo is effective against fungi, bacteria and insects. However, ACA is eco-toxic non-degradable.

  • CCB and CCBF  - commercially ASCU.

  • Boric acid, borax and boron are cheaper than CCA and less poisonous. This is used at a concentration of  2.5 per cent each, to be dissolved in hot water. The preservative, (disodium octaborate- which forms as a result of the reaction), is easily soluble in water. This process is only recommended for bamboo culms that would not be exposed to water or rain. Boron salts are effective against borers, termites and fungi (except soft rot fungi), and is widely recognized to be environmentally acceptable and safe for the mammals.

  • Other alternatives methods:Treatment of bamboo with limewater.

  • Drying of bamboo before use is necessary since dry bamboo is stronger and less susceptible to biological degradation than moist bamboo. In some experiments carried out it was found that Acetic acid (Vinegar), completely prevented moulds/fungus incidence during the drying process. (Tang et al., 2009).

  • Following the drying, the bamboo is TRADITIONALLY smoked by storing it above a fireplace, to blacken the culm. This, however, may not be necessary if chemical methods are used.

  • Fire Retardant Preservative- This treatment is intended to protect materials against fire as well as decay and insect attack. A mixture of boric acid / copper sulphate / zinc chloride / sodium dichromate in a ratio of 3:1:5:6 is recommended at 25% for indoor and outdoor use

  • For Termites- 1% Dieldrin may be added to the preservative. However, Dieldrin is dangerous, and use is illegal in several countries.

Iron Bamboo- Thyrsostachys Oliveri- Kanak Kainch

Thyrsostachys Oliveri, another of the few "Iron Bamboos", is native to the Thailand, South China and N.E India (Tripura area). It is one of the most important bamboo species, because of its near solid structure and fiber quality. Locally called the Kanak Kaich, its a fairly straight growing mid sized bamboo, with a small spread. Farmers in Katlamara in West Tripura cultivate this bamboo at close spacing of about 2.5 m x 2.5 m.

I found this IRON BAMBOO species interesting, due to its vigorous growth at a Nursery close to Dehradun. I have, thus planted a few in my little bambusarium, due to its possible applications in the handicraft sector.

Thyrsostachys oliveri is a short rhizomed, perennial, evergreen, clumping/sympodial tropical bamboo, with persistent culm-sheath, which is an identifying feature.

thyrsostachys oliveri consistent culm sheath

The almost straight/erect culms are about 15 - 25 m long; 50 - 70mm in dia and about 40 - 60cm internode.


As an iron bamboo, its valued as an excellent material for house-beams and miscellaneous applications in construction. The culms are used for reinforcing concrete blocks. Local craftsmen use this bamboo for handicrafts- mat-making, basketry, broom handles etc. Its fiber has a dark brown lustre, which makes it a material of choice for handicrafts. In Thailand, the young shoots are harvested for the production of steamed bamboo shoots.

Habitat : This species originates on the low hills forest, open areas at an altitudinal ranges of 500–700 m.

Distribution : Thailand, Myanmar, China - introduced and cultivated in tropical / subtropical Asia (Gamble, 1896; Wu, 2006).

Silvi-cultural management techniques Propagated through air-layering, culm cutting or offset planting.

Local Names :

Thailand;Phai ruak dam

Burma-Thanawa. Thyrsostachys Oliveri is a Native of Burma. (Nayagarh & Ganjam Districts)

Manipur- Keirakwa

Tripura- Kanak Kaich, Busai, Nusai, Nala Bauns

Bamboo Trails- Dendrocalamus Stocksii

I learnt about this near solid, iron-bamboo (Dendrocalamus Stocksii) from an article published by Institute of Wood Science and Technology. The interesting feature was its loose-clumping growth habit, along with a near absence of inter-nodal cavity, thereby making it a suitable candidate for consideration of use to replace wood in certain applications in the handicraft industry. Also alluded to, as an iron-bamboo due to its iron like strength, this species is practically non-existent in N. India. Scientists at FRI and various agricultural institutes need to study the viability of introducing Dendrocalamus Stocksii in the TARAI, which is pretty humid and moist, much like the costal area, where this bamboo is naturally found.


Dendrocalamus stocksii (Munro), synonym Oxytenanthera stocksii / Pseudoxytenanthera stocksiiaabsence (Munro), synonym Oxytenanthera stocksii / Pseudoxytenanthera stocksii

As per the alluded article, Dendrocalamus stocksii is naturally distributed in Central Western Ghats. Locally called - Chivari’, Mes, Konda, Oor-shema, Marihal, Manga etc. D. stocksii has medium sized, stout solid and strong culms. Though the natural distribution of this species is in humid tropics, this species has a wide adaptability and comes up well in tropical humid, sub humid and semi-arid conditions.


Culms are said to be about 8 to 9m, basal dia 25-58mm and internode of 15-30cm, light green in colour, loosely spaced and without thorns. They are solid at the base upto about half the culm height.

Anatomical and Mechanical Properties of Dendrocalamus stocksii

Specific gravity- 0.691

Fibre Diameter (μm)- 16.6

Fibre Lumen Diameter (μm)- 5.7

Fibre length (mm)-3.4

Fibre Wall Thickness (μm)- 10.9

Maximum crushing stress (kg/cm2)- 386

Vascular bundles per cm2- 281

(Source: Rao et al., 2004)

Species Specific gravity MOR (kg/cm2) Max. crushing stress (kg/cm2)
Dendrocalamus stocksii 0.691 620 386
Bambusa nutans 0.603 529 456
Bambusa bambos 0.584 836 572
Dendrocalamus strictus 0.631 734 359
Tectona grandis 0.604 959 532
kN/cm²   spruce   bamboo   steel St37

bending strength   6.8   7.6-27.6   14
shearing strength   0.7   2.0   9.2


The compressive strength of bamboo is roughly situated between 40 and 80 N/mm2 which is twice to four times the value of most timber species. Bamboo with low moisture content has a higher compressive strength than one with higher moisture.

The shear strength of bamboo is often twice the value of popular timber species.

The bending strength of most bamboo species varies between 50 and 150 N/mm2 and is on average twice as strong as most conventional structural timbers
