Plants are known to absorb the atmospheric carbon by photosynthesis. This absorbed carbon is stored in various organic forms and helps to produce the biomass. The absorption of the atmospheric carbon is depend on the structure and life form of the plants. Trees dominate this process. Greater and taller is the size of the tree more is the amount of carbon fixed. Hence trees are the major plant forms to absorb maximum atmospheric carbon and biomass production. Thus, the present investigation was carried out to calculate the carbon sequestration of 22 standing tree species in Amrai Park of Sangli city. The biomass and total organic carbon of standing trees is estimated by the non destructive method. The population of Swieteniamahagoni(C) Jacq.is more in the campus and it sequestrates the 77509.25 lbs carbon/year.

Mangroves or all the plants are known to absorb the atmospheric carbon by photosynthesis. This absorbed carbon is stored in various organic forms and helps to produce the biomass. Trees dominate this process. Greater and taller is the size of the tree more is the amount of carbon fixed. Hence trees are the major plant forms to absorb maximum atmospheric carbon and biomass production. Thus, the present investigation was carried out to calculate the carbon sequestration of 12 standing mangrove tree species in Achara estuary of Sindhudurg district of Maharashtra state. The biomass and total organic carbon of standing trees is estimated by the non-destructive method. The population of Avicennia marina var. acutissima Staf. & Mold. and Rhizophora mucronata Lamk. are more in the estuary and they sequestrate about 585.70×106 and 375.10×106 lbs carbon respectively. A total of 1892.96×106 lbs of the carbon is sequestering by all the mangrove trees present in the estuary.

<p>Currently atmospheric carbon has reached 405 ppm or 720 GtC.  As is widely known, this increasing atmospheric carbon dioxide, methane and nitrous oxide are primary contributing factors in increasing global temperatures.  Current measurements show that sources of emission such as the burning of fossil fuels contributes 9.9 GtC/yr, while land use change contributes 1.5 GtC/yr. We have identified that crops possessing a subsurface rhizome in particular, in addition to high root biomass, are essential and capable of increasing crop derived soil carbon sequestration by 10-fold.  If the presence of a high biomass rhizome were bred into the world’s major grain crops wheat, rice, maize, barley, sorghum and millets and grown worldwide in no-tillage conditions, these crops could sequester and offset current carbon emissions by 9Gt carbon on a yearly basis. We have developed a new ground penetrating radar instrument and analytical software, which will be presented, as a needed for high throughput non-destructive phenotyping, selection and speed breeding new high root biomass cultivars of the worlds major cultivated crops and forages as a key component for crop-based carbon sequestration driven climate change mitigation. </p>

Abstract Key message The deadwood of different tree species with different decomposition rates affects soil organic carbon sequestration in Estonian and Polish forests. In warmer conditions (Poland), the deadwood decomposition process had a higher rate than in cooler Estonian forests. Soil organic matter fractions analysis can be used to assess the stability and turnover of organic carbon between deadwood and soil in different experimental localities. Context Deadwood is an important element of properly functioning forest ecosystem and plays a very important role in the maintenance of biodiversity, soil fertility, and carbon sequestration. Aims The main aim was to estimate how decomposition of deadwood of different tree species with different decomposition rates affects soil organic carbon sequestration in Estonian and Polish forests. Methods The investigation was carried out in six forests in Poland (51° N) and Estonia (58° N). The study localities differ in their mean annual air temperature (of 2 °C) and the length of the growing season (of 1 month). The deadwood logs of Norway spruce (Picea abies (L.) Karst.), common aspen (Populus tremula L.), and silver birch (Betula pendula Roth) were included in the research. Logs in three stages of decomposition (III–V) were selected for the analysis. Results There were differences in the stock of soil organic carbon in two experimental localities. There was a higher soil carbon content under logs and in their direct vicinity in Polish forests compared to those in the cooler climate of Estonia. Considerable differences in the amount of soil organic matter were found. The light fraction constituted the greatest quantitative component of organic matter of soils associated with deadwood. Conclusion A higher carbon content in surface soil horizons as an effect of deadwood decomposition was determined for the Polish (temperate) forests. More decomposed deadwood affected soil organic matter stabilization more strongly than less decayed deadwood. This relationship was clearer in Polish forests. Higher temperatures and longer growing periods primarily influenced the increase of soil organic matter free light fraction concentrations directly under and in close proximity to logs of the studied species. The slower release of deadwood decomposition products was noted in Estonian (hemiboreal) forests. The soil organic matter mineral fraction increased under aspen and spruce logs at advanced decomposition in Poland.

Sedimen inti dianalisis secara vertikal untuk memprediksi perubahan lingkungan saat sedimen terendapkan. Perairan segitiga Laut Jawa-Selat Makassar-Laut Flores (JMF) dilalui jalur arus lintas Indonesia/ARLINDO. Distribusi aliran ARLINDO yang masuk ke Selat Makassar terbagi dua arah aliran karena adanya Ambang Dewakang. Satu mengalir ke arah Tenggara melalui Laut Flores, sementara itu aliran lainnya bergerak ke arah Baratdaya menuju Selat Lombok melalui Laut Jawa. Penelitian ini menganalisis sedimen inti dari perairan Laut Jawa yang diwakili oleh Lereng Kangean. Metode penelitian menggunakan metode non-destructive yaitu pengamatan megaskopis dan pemindaian, dan metode destructive yaitu pencuplikan sistematis menggunakan 2 cm setiap interval 4 cm.

Soil organic carbon sequestration potential of different tree was analyzed in every year. Five years after plantation average soil organic carbon was recorded highest under fast growing non legume trees (1.82 %) followed by medium growing (1.72 %) and then slow growing (1.60 %). SOC sequestration potential of legume tree species was significantly lower. It was 1.80 % under fast growing legumes, 1.58 % in medium growing and 1.55 % in slow growing legume trees. On individual comparison of non legume trees, Anthocephalus chinensis found to sequester more (1.98%) carbon as soil organic carbon followed by Trewia nudiflora (1.66%), Alstonia scholaris (1.62%) and Lagerstroemia.speciosa (1.57%). Lowest soil organic carbon sequestration was found under Chukrasia. tabularis (1.26%). No significant difference was observed in SOC sequestration potential between Dipterocarpus retusus, Artocarpus chaplasha, Ficus hispida, Mallotus albus, Litsea nitida, Castanopsis indica, Taphrosia candida, Albizzia procera and A. lebbek.

<p>Penelitian ini bertujuan untuk menentukan senyawa organik khususnya organic karbon terlarut (DOC) dari dua spesies daun tumbuhan (<em>wandoo eucalyptus </em>and <em>pinus radiate, conifer</em>) yang larut dalam air selama periode 5 bulan leaching eksperimen. Kecepatan melarutnya senyawa organic ditentukan secara kuantitatif dan kualitatif menggunakan kombinasi dari beberapa teknik diantaranya Total Organic Carbon (TOC) analyser, Ultraviolet-Visible (UV-VIS) spektrokopi dan pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS).</p><p>Hasil analisis DOC dan UV menunjukkan peningkatan yang tajam dari kelarutan senyawa organic di awal periode pengamatan yang selanjutnya berkurang seiring dengan waktu secara eksponensial. Jumlah relatif senyawa organic yang terlarut tergantung pada luas permukaan, aktifitas mikrobiologi dan jenis sampel tumbuhan (segar atau kering) yang digunakan. Fluktuasi profil DOC dan UV<sub>254</sub> disebabkan oleh aktifitas mikrobiologi. Diperoleh bahwa daun kering lebih mudah terdegradasi menghasilkan senyawa organic dalam air dibandingkan dengan daun segar. Hasil pyrolysis secara umum menunjukkan bahwa senyawa hidrokarbon aromatic dan fenol (dan turunannya) lebih banyak ditemukan pada residue sampel setelah proses leaching kemungkinan karena adanya senyawa lignin atau aktifitas humifikasi mikrobiologi membuktikan bahwa senyawa-senyawa tersebut merupakan komponen penting dalam proses karakterisasi DOC.</p>
