Fertilizer Technology | Biochar based Organic Soil Amendment Technology (BIOSAT) by Anulekh.

Application rates over a period of time:
Most soil scientists recommend an application rate of 3-5 tons/hectare/year

Frequency:
Biochar can be applied annually to the soil during the soil preparation stage. It is observed that soil fertility increases over the years due to regular application of biochar.

Method of application:
1. Surface application (Conventional, Horticultural, Tree crops & Landscaping)

2. Spread & incorporate into topsoil (Conventional, Horticultural & Landscaping)

3. Banding (Conventional & Horticultural crops)

4. Localized application (Conventional, Horticultural, Tree crops & Landscaping)

5. Surface application (Landscaping)

6. Turf whole application (Landscaping)

BIOSAT advantage over alternatives:
BIOSAT is an organic soil amendment which is rich in organic carbon. A significant percent of the organic carbon is recalcitrant in nature.
Recalcitrant organic carbon does not decompose easily in soil & keeps performing long after soil application.
This ensures long term soil fertility unlike synthetic chemical fertilizers & other organic soil conditioners that only provide short term benefits.
Chemical fertilizers & other organic soil conditioners have to be replenished regularly to ensure effectiveness.
