Fourfold Increase in Pumpkin Yield in Response to Low-Dosage Root Zone Application of Urine-Enhanced Biochar to a Fertile Tropical Soil

Abstract

A widely abundant and invasive forest shrub, Eupatorium adenophorum, was pyrolyzed in a cost-efficient flame curtain kiln to produce biochar. The resulting biochar fulfilled all the requirements for premium quality, according to the European Biochar Certificate. The biochar was either applied alone or mixed with fresh cow urine (1:1 volume) to test its capacity to serve as slow release fertilizer in a pumpkin field trial in Nepal. Treatments included cow-manure compost combined with (i) urine-only; (ii) biochar-only or (iii) urine-loaded biochar. All materials were applied directly to the root zone at a biochar dry matter content of 750 kg·ha−1 before seeding. The urine-biochar treatment led to a pumpkin yield of 82.6 t·ha−1, an increase of more than 300% compared with the treatment where only urine was applied, and an 85% increase compared with the biochar-only treatment. This study showed for the first time that a low-dosage root zone application of urine-enhanced biochar led to substantial yield increases in a fertile silt loam soil. This was tentatively explained by the formation of organic coating of inner pore biochar surfaces by the urine impregnation, which improved the capacity of the biochar to capture and exchange plant nutrients.

 

Farmers learn to make ‘biochar’ ‘tech

"TO reduce the trash generated by Cebu City daily, around 100 farmers and leaders were trained by the City Government and the Department of Environment and Natural Resources (DENR) 7 recently on biochar technology."

Biochar action at Masarang foundation, Indonesia

The following link leads to a summary on biochar activities at Masarang. I'm a little late finding this but the action is ongoing...
http://masarang.nl/en/?s=biochar&ixsl=1
There are some strong links here to long term haze solutions.

“Nature conservation through collaboration with and development of the local population”

That is the mission of Masarang, our foundation in Indonesia, founded in 2001 by Dr. Eng. Willie Smits.
Masarang finds solutions for the most urgent global problems of our time: deforestation, biodiversity loss, climate change, poverty and underdevelopment.

The Warm Heart FC Trough

The Warm Heart FC Trough

The Warm Heart team has been developing a new type of flame cap / flame curtain (FC) biochar production unit. These are FC Trough units, which are defined as above ground FC units with a non-square, rectangular top aspect.
The general design was developed as a result of considering the easiest low tech way to pyrolyze a great variety of the feedstock types available to the small holders in developing countries, that is, with a minimum amount of processing &/or transportation of the feedstock beyond the initial harvesting.

Given this economy of effort/cost and the basic growth pattern of much potential feedstock, the design will be of interest to the small to medium low tech, distributed biochar makers in developed regions. These are derivatives of the original Japanese technology and are Top Fed Open Draft FC units and not to be confused with kilns since they do not fit the Standard English definition of kiln.
The Warm Heart team took the basic FC trough concept and, with the support of management, come up with a special FC Trough design which features reduced weight without sacrificing durability and without greatly increasing fabrication cost or difficulty.

This is accomplished by reducing the thickness of the firebox sheet metal and laying out the base and long sides as a single rectangular panel so that the sides are simply bent up from the central base section of the panel at the desired angle.

The ends are inverted isosceles trapezoids congruent with the outline of the bent base and long sides. They are welded on at right angles to the base. This lightweight fire box is cradled in a light weight supporting frame made of box iron (or square iron – iron bars with a hollow square cross section).
To further strengthen the unit and secure the firebox in place, four angle irons encircle the top of the unit with the downward facing arms on the inside of the unit and the opposite arms making the uppermost rim of the unit. Thus the firebox rim is sandwiched between the box iron cradle rim and the angle iron (See schematic details, photos 22 &23).
This basic concept will be referred to as the Warm Heart Trough design.

Biochar technology for mine rehab - Philippines

http://www.philstar.com/business/2016/08/30/1618467/biochar-technology-mine-rehab

"Nickel mining companies Marcventures Mining and Development Corp. (MMDC) and Benguetcorp Nickel Mines Inc. (BNMI) have been given the green light by the Department of Environment and Natural Resources to engage in a mine rehabilitation project using activated biochar technology. According to Marcventures vice chairman Isidro “Butch” Alcantara, the project is not only in compliance with the new policy direction of the DENR to rehabilitate mined-out areas, but also complements the Surigao nickel miner’s initiatives in providing sustainable, organic and environmentally enhancing livelihood activities." ...
