Biochar merupakan material baru yan

Biochar merupakan material baru yang diteliti secara intensif dalam waktu sepuluh tahun terakhir di berbagai penjuru dunia. Hal ini dipicu oleh fakta bahwa tanah-tanah Terra Preta di wilayah Amazon, Amerika Selatan, dikenal sangat subur karena mengandung arang yang dibentuk dari pembakaran minim oksigen (pirolisis) di jaman ribuan tahun yang lalu. Dalam kondisi kemajuan teknologi seperti sekarang ini para peneliti mencoba untuk meniru dalam memperoleh material serupa yang kemudian dikenal secara luas dengan istilah biochar dan menguji manfaatnya terutama untuk perbaikan kondisi tanah agar menghasilkan pertumbuhan dan produksi tanaman yang lebih baik dan sekaligus mampu menjadi penghambat lepasnya karbon ke atmosfir (carbon sequestering).
Sebagai sebuah topik riset yang baru tentu saja dapat dipahami bahwa hal tersebut menimbulkan pro- dan kontra, khususnya yang menyangkut manfaat positif secara luas. Salah satunya yang pro- adalah yang ditulis oleh Lehmann & Joseph (2010) yang berjudul Biochar-Environment Management-Science and Technology. Sebaliknya yang kontra adalah yang disajikan oleh F. Verheijen et al. (2010) yang berjudul Biochar Application to Soils. Uraian berikut ini mencoba untuk melihat dari dua sudut tersebut untuk memberikan gambaran yang sebenarnya bagi para calon peminat riset dan/atau pengguna biochar untuk kepentingan perbaikan kesehatan dan produktivitas tanah. Pada akhir uraian disampaikan perlunya persyaratan mutu bio-char untuk memperoleh hasil yang dapat diperbandingkan.

Biochar is a new materials researched intensively within the last ten years in various parts of the world. This is fuelled by the fact that the lands of Terra Preta in the Amazon region of South America, is known to be very fertile because it contains charcoal that was formed from the minimal oxygen combustion (pyrolysis) at times thousands of years ago. Under the conditions of technological advances like this now researchers tried to replicate in obtaining similar material which was then widely known by the term ' biochar ' and test its usefulness mainly to improved soil conditions in order to generate growth and better crop production and at the same time capable of being a barrier to the release of carbon into the atmosphere (carbon sequestering).As a new research topic of course understandable that it raises and the pro-cons, especially regarding the positive benefits widely. One of the pro-was written by Lehmann & Joseph (2010) entitled ' Biochar '-Environment Management-Science and Technology. Otherwise the cons are presented by f. Verheijen et al. (2010) entitled Biochar Application to Soils. The following description is trying to look at it from two angles to give the real picture for the candidate being research and/or users of biochar in the interest of improved health and productivity of the soil. At the end of the explanation presented the necessity of quality requirements of bio-char to get results that can be compared.

Biochar is a new material studied intensively in the past ten years in various parts of the world. This was triggered by the fact that the Terra Preta soils in the Amazon region, South America, known to be very fertile because it contains charcoal formed from burning minimal oxygen (pyrolysis) at the time of thousands of years ago. In conditions of technological advances, as now researchers are trying to replicate in obtaining similar materials are then widely known by the term biochar and test its benefits, especially for the improvement of the condition of the soil in order to generate growth and yield better and at the same time is able to become an obstacle to the release of carbon into the atmosphere (carbon sequestering).
As a new research topic of course be understood that it raises the pro and cons, especially regarding the positive benefits widely. One of the pro is written by Lehmann and Joseph (2010), entitled Biochar-Environment Management-Science and Technology. Otherwise the counter is presented by F. Verheijen et al. (2010) entitled Biochar Application to Soils. The following descriptions are trying to look at from two angles is to provide a true picture of the prospective applicants for research and / or users of biochar to the benefit of improved health and productivity of the soil. At the end of the description given the need for quality requirements of bio-char to obtain comparable results.
