Experiment: Growing Bamboo for fodder

Turns out just about every livestock animal enjoys bamboo at different stages of its growth. Chickens will eat new shoots, cows/horses will graze the foliage and goats will browse any part of it that isn’t overly mature/woody.


About Bamboo:

I’ll always remember a poem from one of my rather-hippie forest ecology professors:

“Sedges have edges, rushes are round, grasses have joints unless there are cops around.”

Therefore, bamboo is technically a grass!

Found on bamboofarmingusa,com, 2 laboratory analysis reports were shared that break down the nutrient content of bamboo.

From Dairy One Forage Testing Laboratory (PDF Link):



From the North Carolina Department of Agriculture and Customer Services:


The crude protein figures above are high enough to be considered a “Premium” grass hay by USDA guidelines (retrieved from Oregon State University). Bamboo requires significant amounts of nitrogen so some sort of legume ground cover (likely peas or clover) would be a natural companion for the bamboo stands.

Letting animals graze bamboo also has the subjective benefit of breaking the monotonous boredom of extended hay feeding. As bamboo is an evergreen perennial, the stands could be opened to grazing in winter. I am not sure how nutrient composition changes with winter dormancy though.

Containing the potentially invasive bamboo:

Growing up in a metropolitan area that has spent countless resources battling the encroachment of bamboo, I want to take steps to ensure it remains contained. Originally meant for containing hops plants from taking over the garden, physical root barriers were actually invented with bamboo in mind.

Here are my two favorites on Amazon:

18″ x 100 ft

24″ x 100 ft


Time will tell how this experiment goes!

A friend brought up an interesting point in a comment on yesterday’s blog post. There is a species of bamboo native to Virginia and the Southeast US called Giant Cane. He provided a descriptive PDF from the USDA that explains the historical value and use of the plant. My favorite passage states:

According to environmental
historian Mart Stewart (2007), “Modern studies
have established that cane foliage was the highest
yielding native pasture in the South. It has up to
eighteen percent crude protein and is rich in
minerals essential for livestock health.” Livestock
eagerly eat the young plants, leaves, and seeds and
stands decline with overgrazing and rooting by hogs
(Hitchcock and Chase 1951).

Which demonstrates the plant is on par with bamboo as a nutrition source for livestock. Not to mention the renewable building material provided by mature stems. I could build chicken coops, green/hoop houses, storage sheds, etc. Interesting stuff to say the least!

Purchased Tanks for Water Collection: Warnings and Advice

I have been browsing craigslist regularly for anything from animals to equipment to discarded plastic drums for water tanks. After doing some extensive math that will be included in a future series of posts, I quickly realized that the rainwater collection system would be best served with a higher capacity than 55 gallon drums could accommodate reasonably.

Off to Craigslist in search of some of the 250+ gallon tanks that come in metal cages, pictured below.

Water Tank

First for the warning: Like 55 gallon plastic drums, be VERY particular to source a tank that stored food materials or safe chemicals. Watering animals, plants or yourself with water tainted by industrial-grade acid, chemicals, etc would be tragic and entirely avoidable.

Advice: Don’t write off tanks with chemical stickers like I almost did. Luckily the craigslist ad for 300 gallon tanks had a price that made me inquire despite almost dismissing the option due to visible chemical stickers on the tanks. Here is a picture from the ad:


Turned out the tanks contained medical grade Hydrogen Peroxide. The seller of the tanks explained that he does not clean them out as the solution keeps the inside of the tanks sterile. All that is needed to make them food-safe is to add 10 gallons of water, slosh it around and dump it out as the trace amounts of it have been diluted to ~1% and will break down into water + oxygen gas once exposed to light.

Self-sanitizing 300 gallon tanks at twice the local going rate for 55 gallon drums? I took as many as I could safely haul at once and may go back for more. They would make the perfect mobile watering tank for cattle, rain barrels or even a tank to combine smaller rain water containers together! Also I am sure they could be used to barter with other farmers/gardeners if I find myself with too many in the end.

To recap, when sourcing potential water tanks, be very careful to determine exactly what they held previously. If they were used for non-food uses, see if there is a way to make them food safe before writing them off. After all I much prefer my Hydrogen Peroxide container to the cleaning I’ve done in the past to an agave or honey container!

Carbon Medium for Nutrient Absorbtion in Compost while Wintering Animals

Follow up to Wintering Animals = Backbone of Soil Building

Capturing all of the nutrient rich excrement from the wintering of animals is going to require a huge amount of carbon. Skills I have gained while studying forestry and the associated graduate projects I assisted will be called upon in order to accumulate the carbon biomass I will require. I’ll write a well-cited post on my sustainable forest management plans once I have finished collecting and amassing my research. The gists of my strategy will be to provide the canopy disturbance necessary to have a healthy, sustainable forest.

Good points were made in Joel Salatin’s book, Folks, This Ain’t Normal. Starting around page 182, Salatin asserts that soil is built and carbon sequestered more efficiently via grasslands opposed to forests. Trees grow very slowly, then die. As they decompose, much of that sequestered carbon is released right back to the atmosphere. Grasslands grow, die and decompose every year; multiple times a year if serviced by grazers and herbivores. However the sequestered carbon in the grasslands us more fully absorbed by the soil and stored in the animal tissue of grazers. Salatin’s assertions seem to be backed up by this study I found.

To minimize the negative impact of forest land on the atmosphere, I plan to eventually harvest the dead, diseased, crooked or otherwise undesirable trees from the forest to make room for subsequent generations of oak and hopefully someday soon, American Chestnut. Despite my minor in forestry, I have a lot more to learn about sustainable harvesting. Fortunately, there are many pioneer trees in the pasture that need removed, and the unmaintained forest has many dead trees that should sustain me for at least a year while I broaden my forestry knowledge.

I will likely invest in a wood chipper to process the farms own biomass to provide the winter bedding. I may also seek out locally discarded christmas trees, shredded paper/cardboard, peanut hulls (suggested by Mr. Salatin in our correspondence) or any other source of easily attainable carbon material.

Note: If you plan to store wood chips on your farm, please be sure to do so in a manner that accounts for the heat generated as they naturally decompose. Limit the height of piles to prevent a fire hazard in your structures and to ensure that the chips dry fully.



Calculating Cattle Needs

In my previous post, I decided to start with a paddock size of 5,000 square feet. Joel Salatin at Polyface Farm has recommended in the past to use 200 square feet per cow-calf pair per day.

I adapted that figure to 300 square feet per pair per day as the pasture I will be using has been unmaintained for about a decade. So until I see how much the cattles graze, I am going to be very conservative. The beauty of Managed Intensive Rotational Grazing (MIRG) is that I can easily change on the fly if required.

So theoretically, each daily-use paddock: (5,000 ft^2) / (300 ft^2/pair/day) means I can support 16 and 2/3 cow-calf pairs a day.

I made an interactive spreadsheet to automate these calculations for different scenarios, but I will save that until I dig more into the economics of cattle.
