Biochar

My big question, what are gained  advantages of biochar over:
a) inorganic fertilizer,
b) organic fertilizer,
d) animal mature,
To peasant farmers in developing countries? These farmers don't have tools to vet soils for biochar applications as most papers defines application of biochar.

As a smallholder you can make it yourself in low cost pit kilns and TLUDS, plant it with manure, and save the cash you would have used to buy commercial fertilizer. Your rewards are a healthier crop with a higher yield and healthy productive animals. Less disease enables increased egg and milk production. See Warmheart Worldwide Malawi, Biochar for Sustainable soils (B4SS) biochar.international or any number of reports from South Asia. In Malawi and Kenya hundreds of smallholders have now been trained to make and use biochar in a program that has little to no budget but lots of enthusiasm and great guidance. It works, so farmers enthusiastically volunteer to train others.

Advantages over:

  1. Commercial fertilizer – improved soil fertility, water conservation, improved plant health, improved yield
  2. Organic fertilizer – accessibility. It is easy to make and compatible with organic fertilizer and manure
  3. Animal manure – used with manure as a nutrient source it retains nutrients and releases them more gradually to the soil. It is a great companion for manure or for composting with manure.  

 

Not much research is done on the very poor and often disturbed soils where smallholders have their garden plots. Most research seems to be directed to mid-sized or large scale farmers. It would be useful to have soil scientist in developing countries monitor and evaluate why biochar works so well in different circumstances. NGOs in Africa tell us that they “don’t have the bandwidth” to include biochar in their programs, yet those that do see good success.   

 

Just add biochar!

Dear Peter,

Perhaps this paper has something for you: 

Robb, S., Joseph, S., Aziz, A. A., Dargusch, P., & Tisdell, C. (2020). Biochar’s Cost Constraints are Overcome in Small‐Scale Farming in Tropical Soils in Lower‐Income Countries. Land Degradation & Development, ldr.3541. https://doi.org/10.1002/ldr.3541

From the Abstract: “... yield increases in highvalue crops in tropical locations with low incomes and biocharfocused smallscale production, were overall significant predictors of biochar scenario financial feasibility. ... the average abatement cost of biochar applied in ‘lowerincome countries' is [(negative)] US$58 Mg1 CO2e (financially feasible) ... biochar fertilizers ... could present a commercially feasible pathway for biochar valuechain development in higherincome countries.”

Best Wishes,
Robert Gillett
