The provision or application of biochar to agricultural land follows the 4Rs rule, namely the right source (appropriate biochar raw material), right place (appropriate application area), right rate (appropriate dosage) and right timing (appropriate time). The physical and chemical properties of biochar differ depending on the raw material and production process. By following the 4R rules, biochar performance can be maximized. The effect of biochar on plants will be clearly visible (significant) when the 4R rules are met. With a dose / rate reaching 20 tons / ha (depending on the influencing condition factors), the need for biochar is also large. This is why biochar products are rarely sold online, namely because of the large volume.
Unlike soil amendments such as compost, the effects of biochar can be felt for quite a long time or for several types of agricultural crops, namely not only in one planting season, but repeatedly. This also makes the provision or application of biochar not as frequent as compost. And in the end, of course, the economic aspect is a determining parameter whether biochar makes agricultural businesses more profitable or not. The price of biochar on the market is an important concern for users or farmers.
The lack of biochar
production in Indonesia is currently a barrier to biochar application
in large agricultural lands, even when farmers' awareness of biochar is
also increasing. This is the driving force for the importance of
adequate biochar production, especially industrial capacity. Only with
adequate biochar production can biochar application in agricultural
lands or degraded lands be carried out optimally. The urgency of
industrial capacity biochar production is even greater, especially when
the biochar production also gets carbon credit, of course this will be
even more interesting.
