Aim: To evaluate the physico-chemical and hydrological characteristics of cocopith, perlite, vermicullite, vermicompost, sand, rice husk, paddy straw, saw dust and rock wool for using them as substrates for soilless agriculture. Methodology: The soilless substrates were initially evaluated for pH and EC, and then estimated for total organic carbon by dry combustion method, total nitrogen by Kjeldahl digestion method, potassium by atomic absorption and phosphorus by colorimetric method. The hydrological properties of substrates were estimated by Keen - Rackzowski box method. Results: The desirable level of physical properties of bulk density (0.47 gm cm-3), particle density (0.63 gm cm-3), total porosity (75.81%) and chemical properties of pH (6.23), EC (5.02 dS m-1), total organic carbon (36.39 %), and other properties were noticed under cocopith. The maximum level of water holding capacity (769.30 %) and volume of expansion (185.78 %) was registered by cocopith. Interpretation: Cocopith has favourable hydrological properties with desirable level of physical and chemical properties, which makes it the best medium for soilless agriculture. Coconut fiber is a characteristic natural fiber from the external husk of coconut and its extraction process also without polluting nature.

ABSTRAKNORM (Naturally Occuring Radioactive Material) merupakan unsur radionuklida yang secara alami sudah ada dalam bumi dan kandungannya dapat meningkat dengan adanya kegiatan industri, seperti PLTU. Kegiatan PLTU menghasilkan bottom ash dan fly ash yang akan terbawa oleh angin kemudian masuk ke perairan dan mengendap pada sedimen dasar perairan. Penelitian ini bertujuan untuk mengetahui aktivitas NORM pada sedimen dasar terkait kegiatan PLTU Tanjung Jati, Jepara dan hubungannya dengan ukuran butir serta TOC (Total Organic Carbon). Pengambilan sampel dilakukan dengan metode purposive sampling. Pengukuran konsentrasi aktivitas NORM dilakukan menggunakan spektrometri sinar gama detektor HPGe, di Laboratorium Radioekologi Kelautan PTKMR-BATAN. Konsentrasi aktivitas NORM yang terdeteksi yaitu 40K berkisar 442,75–818,40 Bq.Kg-1, 232Th berkisar 99,19–212,34 Bq.Kg-1 dan 226Ra berkisar 42,42–77,77 Bq.Kg-1. Aktivitas NORM menunjukkan adanya hubungan dengan tekstur sedimen, tetapi tidak menunjukkan hubungan dengan kandungan Total Organic Carbon (TOC).ABSTRACTNORM (Naturally Occurring Radioactive Material) is a radionuclide element which naturally exists in the earth and its content can increased with the presence of industrial activities, such as the PLTU. The PLTU activities produce fly ash and bottom ash which will be carried away by the wind and then fall in the waters and settle on the bottom sediments of the waters. This study was aimed to determine the activity of NORM in bottom sediments related activities PLTU Tanjung Jati Jepara and its relationship with grain size and TOC (Total Organic Carbon). Sampling was conducted by purposive sampling method. NORM activity concentration measurements performed using gamma ray spectrometry HPGe detector, in Marine Radioecology Laboratory PTKMR-BATAN. NORM activity concentration detected is 40K ranged 442.75 to 818.40 Bq.Kg-1, 232Th ranged 99.19 to 212.34 Bq.Kg-1 and 226Ra ranged 42.42 to 77.77 Bq.Kg-1. NORM activity shows the relationship with sediment texture, but does not show a relationship with the composition of Total Organic Carbon (TOC).

Successive applications of liquid swine waste to the soil can increase the contents of total organic carbon and nutrients and change acidity-related soil chemical properties. However, little information is available on the effects of swine waste application in solid form, as of swine deep-litter. The objective of this study was to evaluate alterations of organic carbon and acidity-related properties of a soil after eight years of pig slurry and deep-litter application. In the eighth year of a field experiment established in Braço do Norte, Santa Catarina (SC) on a sandy Typic Hapludalf samples were taken (layers 0-2.5; 2.5-5; 5-10; 10-15; 15-20 and 20-30 cm) from unfertilized plots and plots with pig slurry or deep-litter applications, providing the simple or double rate of N requirement of Zea mays and Avena strigosa in rotation. Soil total organic carbon, water pH, exchangeable Al, Ca and Mg, and cation exchange capacity (CECeffective and CECpH7.0), H+Al, base saturation, and aluminum saturation were measured. The application of pig slurry and deep-litter for eight years increased total organic carbon and CEC in all soil layers. The pig slurry and deep-litter applications reduced active acidity and aluminum saturation and increased base saturation down to a depth of 30 cm. Eight years of pig slurry application did not affect soil acidity.

Potential Production

The horizons in soil profile will determine the magnitude of greenhouse gas production due to the difference of total organic carbon and other chemical properties. This study aimed to determine the potential production of methane (CH<sub>4</sub>) and nitrous oxide (N<sub>2</sub>O) in each horizon of soil profile from organic and conventional rice fields. Soil samples which were taken from Imogiri Bantul D.I. Yogyakarta were used to determine soil properties, the potential of CH<sub>4</sub>, and N<sub>2</sub>O productions. The correlation analysis was used to determine the relationship between the production of CH<sub>4</sub> and N<sub>2</sub>O with soil properties. The results showed that production of CH<sub>4</sub> and N<sub>2</sub>O will be decreased with the increase of soil depth. Production of CH<sub>4</sub> and N<sub>2</sub>O was higher in organic rice field than in conventional rice field. The total organic carbon (TOC) correlated positively with CH<sub>4</sub>-production (<em>r=0</em><em>.89, P&lt;0.001, n=8</em>) and N<sub>2</sub>O-production (<em>r=0</em><em>.87, P&lt;0.001, n=8</em>). The nitrogen content also correlated positively with CH<sub>4</sub>-production (<em>r=0</em><em>.87, P&lt;0.001, n=8</em>) and N<sub>2</sub>O-production (r=0.94, P&lt;0.001, n=8). Mitigation of CH<sub>4</sub> and N<sub>2</sub>O emissions should consider of C and N in the soil.

The aim of the presented research was to examine the concentration of biogenic compounds and heavy metals in the bottom sediments of the Sulejów Reservoir (Central Poland) from October 2018. Based on the obtained research results, maps of the spatial distribution were prepared. The following parameters were analyzed: total phosphorus (TP), total Kjeldahl nitrogen, total organic carbon (TOC), ratio of total organic carbon to nitrogen (C:N), organic matter content as well as Cd, Cr and Pb concentrations. The sediments were collected at 28 sampling sites, covering the whole area of the reservoir. The differences in the content of individual biogenic compounds result from the composition of the debris applied by the supplying rivers, as well as the content of this elements in the water, long retention time (40 days) and depth from which the tested sediments were taken. The distribution of examined compounds was largely influenced by the agricultural activity in the studied area, as well as the presence of ports and recreational points. Based on the measurements, the highest amounts of biogenic components deposit in sediments of deep parts in slow-flowing waters, in stagnation zones, areas adjacent to arable land, and the sites where fine-size fractions prevail in the deposited material. Biogenic compounds in sediments of the Sulejów Reservoir showed a pattern of gradual increase along the reservoir from lower values in the back-water part. A similar relationship is visible for heavy metals. Referring to the ecotoxicological criteria, it can be stated that bottom sediments from the Sulejów Reservoir collected in 2018 are not toxicologically contaminated in terms of cadmium, lead and chromium content.

Carbon Determination

A relationship among total organic carbon content determined by ignition loss (LOI) and DUMAS combustion methods, were perfomed in evergreen Andean eyebrow forest soils, southwestern zone of Sangay National Park- Ecuador, where three conglomerates were established as follows: (C) with five plots (P) with plots of 20 x 20 m. In each plot, five digging trenches and four soil samples were carried out at different depths: 0-10, 10-20, 20-30 and> 30 cm, respectively. It is observed that the amount of total organic carbon obtained by the DUMAS and LOI method (R2 = 0.99) does not differ significantly. However, the DUMAS total organic carbon determination methodology showed greater precision with regard to LOI, thus becoming a good alternative to be used as a reference method. In addition, the operability in the laboratory is reflected in the reduction of time and optimization of the human resource. The correlation level shows a low level of significance among these methods, the variation is greater in the DUMAS method (3.38%), due to the analyzed volumes of the samples and the auxiliary equipment level of precision.

<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>
