Climate Farming: Creating healthy, fertile soils with the planting of trees and crops, with recycling organic nutrients, and biochar captured carbon

Keynote by Hans-Peter Schmidt

Trees not only produce timber but animal fodder, nuts, fruits, pharmaceuticals… and shade, nitrogen and carbon for soil fertility. No heavily degraded soil can be regenerated and awaken to life without the planting of trees. Trees are crops that transform the surface of an agricultural field into a much more resilient and efficient multistory eco-system that can produce stable and cash crops and plenty of commodities in parallel.

A farm scale device to carbonize crop waste, animal bones and invasive shrubs will have to be introduced to manufacture a highly porous substance called biochar. This biochar will then be enhanced with liquid organic nutrients and transformed into a highly efficient organic fertilizer that replaces chemical fertilizer while increasing crop yields substantially. Farmers can thus becoming increasingly independent from imported fertilizer and pesticides. Thanks to biochar based fertilizer and soil substrates plants not only grow better and are more resilient during extended dry periods, they also increase plant survival rates especially during reforestation of degraded land.

In our talk we present the basics of these climate farming methods, our experiences with implementing it in different countries and discuss the prospects for its introduction into the Republic of Senegal.

Farm scale biochar production, nutrient enhancement and soil application techniques

Hans-Peter Schmidt

While biochar prices from industrial production are at levels that make its use in most agricultural settings economically non viable, the scenario changes when farmers produce - on farm - their own biochar from residues such as straw, husks, shrubs, cuttings and prunings in smaller scale, low cost biochar kilns. Farmers can thus combine biochar production with on-farm waste management, biomass heat generation and on-site organic fertilizer production, which is a major step towards a more circular economy in agriculture. Using Kon-Tiki type flame curtain pyrolysis systems, the cost per tonne of biochar could come down to below $150 compared to the current market price of €600 to €900 per tonne. Furthermore, as the amount of biochar produced per farm and year would be dependent on the biomass surplus of each farm, it would be in direct relation to the carbon balance and potential of photosynthesis of the farm.
Once a farmer has sufficient high quality biochar at his disposal new roads of nutrient capture and recycling opens up. In mixed-use farms biochar could thus first be used in manure management to decrease nutrient losses, reduce odours and to improve, when applied to soil, the organic fertilizer efficiency while reducing GHG emissions during the whole cascade of use from manure storage, to composting and application. Some of the biochars might even be used as feed additives to initiate the nutrient capturing effect of the biochar already in the digestive system of the animals while improving feed efficiency and animal fitness. Even though scientific proof of the later is still scarce, more than 90% of the biochar holding a European Biochar Certificate (EBC, 2012) is first used in animal farming (partly as a feed supplement and mostly as bedding and manure treatment) and, only after those initial uses, is the biochar used as a soil amendment.
Organic nutrient enhanced biochar can then be used very efficiently in concentrated sub root applications. Instead of spreading large amounts of biochar over the whole field, low amounts of biochar-nutrient slurries are injected into the root zone of the cultivated plants where they and their microbial symbionts benefit from nutrients and water captured in the biochar as well as from the other known qualities of biochar.

Farmer scale biochar production and nutrient enhancement

keynote by Hans-Peter Schmidt

With low cost, on-farm biochar production, biochar could be used in various cascades from silage and animal feeding, to bedding and manure management, to waste water treatment and urine recycling, to grain store house building, as well as vegetable and fruit storage. The potential ubiquity of biochar in many farming processes could improve the ecological and carbon footprint, nutrient cycling and overall sustainability of farming. With each year the amount of biochar and soil organic matter in soil could be increased steadily, creating an expanding carbon sink in agricultural soils. On-farm biochar production could thus be a major step towards a more circular economy in agriculture. 

At the conference, we will present the Kon-Tiki technology and its perspective for on-farm biochar production, its subsequent cascading use and nutrient enhancement. We will further present analytical data of the biochars depending on feedstock, quenching technique and kiln design, emission and yield data as well as a first economic evaluation of the technology both for developing and developed countries. In addition, we will present some first result of farmer trials in Nepal using these biochars.

Hans-Peter Schmidt

To enhance the agronomic effects of biochar several post production treatments might be considered: (1) adding nutrients, (2) inoculating it with beneficial microorganisms, (3) improving its surface reactivity and porous volume and thus its sorption dynamics through traditional activation techniques, and/or (4) accelerated biological aging through composting or fermentation. The different post-production techniques can be classified according to the resulting physical and chemical alteration of the biochar:

1.    Addition of nutrients, microorganisms and/or minerals in liquid solution which soak into the biochar pores without any or with only slight chemical alteration of the biochar. 
2.    Physicochemical activation (treatment with acids, vapours, toasting with minerals …), resulting in alterations of the surface, pore volume and functional groups. 
3.    Biochemical interaction of the biochar with organic compounds, minerals and microorganisms resulting in complexation of the aromatic structure and also partial degradation.

Cascading Uses of Biochar - Hans-Peter Schmidt, Ithaka Institute

In addition to the use of biochar as a soil amendment, there are an increasing number of ways to incorporate biochar into different eco- and industrial systems. Thus feeding biochar to livestock has numerous benefits not only for the animals, but it also helps reduce greenhouse gas emissions and improves nutrient retention in animal manure. The use of biochar in building materials is just beginning to be studied but shows promise in the ability to insulate, decontaminate air, provide odor and humidity control. Biochar as pillow filling to induce perfectly reposing sleep is just another way to benefit from biochar's multiple qualities. There are more than 55 uses of biochar that can be combined in cascades. All of these uses have in common that the biochar gets slowly charged with nutrients, gets oxidized and can finally be recycled as a soil conditioner. This session will introduce participants to a broad range of novel and cascading uses of biochar.
