Biochar: Priority for Soil Fertility or Climate Solution First?

Perspective or point of view on biochar is greatly influenced by a person's expertise, while the driving force of its application is greatly influenced by factors that are the problems of the area or region. For example: climate scientists see soil improvement from biochar applications as an additional benefit (co-benefit). For soil scientists or farmers who use biochar as a soil amendment because of their practical experience that has a positive effect on soil fertility and the economic aspects of their farming, while climate benefits become additional benefits (co-benefits). And in reality the accumulation of benefits (including economic) and the effectiveness of providing environmental solutions will accelerate the use of biochar in the real world.

To maximize the benefits of biochar applications, the quality of biochar becomes very important, or in other words the physical and chemical properties of biochar control the level of its effectiveness for various applications. These properties are determined by factors, namely, raw materials, process conditions and before and after the production process. This is so that the biochar produced has different properties so that laboratory analysis is a method used to predict the effectiveness of the biochar. And also to qualify for certain incentives that apply in certain countries, the biochar produced can also meet certain criteria, for example the standards made by the IBI (International Biochar Initiative). Or to get carbon credit or BCR (biochar carbon removal) credit that has been applied internationally also requires biochar with certain criteria and quality, and for that biochar production must follow a certain methodology according to international carbon standard institutions such as Puro earth, Verra, and European Biochar Certificate (EBC). To get quality parameters or biochar specifications that are in accordance with their use, a certain type of laboratory is needed. Not many laboratories can do this biochar test. Some laboratories that can do this include compost, soil, coal and activated carbon analysis laboratories.

Currently the main and long-standing focus, namely the use of biochar for agriculture, plantations and forestry is to increase productivity / yield. However, in fact the added value that biochar can offer in its application in the soil, especially in cultivation, not only includes increasing crop yields, but also preventing the loss of humus in the soil, preventing nitrate leaching, and increasing water storage capacity to increase plant resistance to drought and its resilience to the climate crisis.
