BIOCHAR & SOIL ENVIRONMENT

5 Feb 2016

BIOCHARBiochar is another name for charcoal used for purposes other than combustion.

Like all charcoal, biochar is created by the pyrolysis of biomass.

BIOCHARS

There are various types of biochars, based on feedstock's and production technologies.

Biochar as

Growth promoter

Soil conditioner

Soil amendment

Traditional use of biochar

BIOCHARCULTUREBiocharculture is a holistic approach that has been historically tested, traditionally practiced, is culturally integral, economically viable, socially responsible, environmentally sustainable, and agreeable as a policy.

The uses of biochar—as part of biocharculture—include its application in the areas of soil management, livestock, biomass energy, water purification, green habitats, sanitation, food, health, etc.

BIOCHARCULTURE ADAPTATION BENEFITS

Securing the crop from drought and climate

variabiiity

Reclaim the degraded soils water conservation

Lessen the impact of hazardous pesticides

and complex chemicals

reducing emissions and increasing the carbon

Conversion of biomass into biochar

Increase in crop yieldincreases in C, N, pH, and available P to the

plants

Impacts of biochar last more than 1000 years.

SUSTAINABILITY OF BIOCHARBiocharculture integration into traditional and local practices should be encouraged. Encouraging local communities to produce and use biochar with locally available raw material is considered sustainable.

Biochar blends are mostly organic / natural

Damage has occurred on 15 percent of the world’s total land area (13 percent light and moderate, 2 percent severe and very severe), mainly resulting from erosion, nutrient decline, salinization and physical compaction.

Developing Countries Climate• Arid and semi-arid areas account for one third of the earth’s surface land

area.• In many parts of the subhumid and semiarid tropics, crop yields are

declining on response to inputs such as fertilizers, and droughts and shortages of irrigation water are increasingly evident.

• Sub-Saharan Africa and Asia pose two different challenges in raising food production to meet their food needs.

• ICRISAT (1998) estimates that semi-arid areas, especially within the tropics, cover most parts of the developing nations in the world including Latin America, most parts of sub-Saharan Africa, a large portion of Eastern and Southern Africa and parts of India and South East Asia.

By 2030 ensure sustainable food production systems and implement resilient agricultural practices that increase productivity and production, that help maintain ecosystems, that strengthen capacity for adaptation to climate change, extreme weather, drought, flooding and other disasters, and that progressively improve land and soil quality

Climate Smart Sustainable agriculture

Today’s challenges for sustainable agricultural development are to respond to increasing demand for food, adjust to rapid climate changes caused by global warming, and reduce agricultural greenhouse gas emissions (FAO 2008a).

Climate change mitigation in agriculture will require more efficient use of fertilizer, soil conservation, and better production management.

Under current fertilization practices, crop plant uptake of nitrogen as a nutrient is about 50 percent, with losses and emissions to the atmosphere through runoff and leaching from soil erosion (Takle and Hofstrand 2008; FAO 2001).

All farmers can adopt biochar, and one need not be

in a hurry to apply large quantities to achieve a bumper yield. Annual

incremental application is more sustainable for the

farmer and for the environment.

Biochar application reduces the burden of farmers in several ways, namely by maintaining and enhancing soil fertility.

Incremental biochar compost application

- Soil microbes adapt to the new environment.

- In the initial phase, some biochar removes salts and other poisons from the soil, which is a process that requires some time. The later subsequent application of biochar compost improves soil conditions.

- With the application of biochar compost structure and texture of the soil changes over a period of time.

- Incremental application addresses the sustainable use of biomass, which is converted into biochar.

- For the user, the burden of the cost of application of biochar compost is not high if applied incrementally.

Biochar protects and enhances both macro and micro biodiversity.

Microbial habitats are enhanced through the unique structure and

properties of biochar. Biochar-amended soils have higher

microbial biodiversity.

Biochar amended soils show high levels of microbial biodiversity.

Biochar is like a coral reef for the soil, creating a great habitat for all

soil life diversity.

Biochar and soil microbes minimize the use of purchasing inputs and

maximize the efficiency of soil microbes use.

The author has developed an area with 200 species of plants

conserved on half–an-acre of land to develop soil microbial culture

for inoculation into biochar.

Physical - Biochar reduces soil bulk density.

- Biochar increases soil aeration.

- Biochar changes the soil structure and texture through changes in physical and chemical properties.

- Biochar lessens the hardening of soils.

- Biochar helps to reclaim degraded soils.

- Increased Cation Exchange Capacity.

Chemical - Biochar reduces soil acidity by increasing pH (also called the liming effect).

- Biochar helps soil retain nutrients and fertilizers (Lehmann, 2006 in Hansen, 2008).

- The application of biochar improves soil fertility via two mechanisms: (1) by adding nutrients to the soil (such as K, to a limited extent P, and micronutrients); (2) by retaining nutrients from other sources including nutrients from the soil itself.

- Biochar increases C, N, and P availability to plants, because biochar absorbs and slowly releases fertilizer.

- Biochar increases in the soil levels of available Ca, Mg, P, and K.

- Biochar helps to prevent fertilizer runoff and leaching, allowing the use of less fertilizer and diminishing agricultural pollution to the surrounding environment.

Biochar mitigates the impact of hazardous pesticides and nitrogen fertilizers on the local environment and ecology.

- Biochar absorbs complex fertilizers and pesticides in soil, thus lessening their impacts.

Biological - Biochar increases soil microbial respiration by creating space for soil microbes.

- It increases soil biodiversity and soil-life density in the presence of organic carbon.

- Biochar increases arbuscular mycorrhizae fungi. Soil aggregation also improves due to increased fungal hyphae.

Biochar helps to lessen the impacts of termites on the biomass in agricultural field.

The presence and density of earthworms increase in soil treated with biochar over time.

Ants are more repellent to the freshly added biochar, and over a period of time the biochar’s impact on ants lessens.
