Decomposition Rates and Nitrogen Release of Turf Grass Clippings

Decomposition rates and N release patterns of turfgrass clippings from lawns are not well understood. Litter bags containing clippings were inserted into the thatch layer of a coolseason turf. The experiment was arranged as a 2 × 4 factorial in a randomized complete block design with three replicates. Treatments included four rates of N fertilizer (0, 98, 196, and 392 kg N ha-1 yr-1) and two clipping treatments (returned vs. removed). Litter bags were removed periodically over the growing season and samples were analyzed for biomass, N and C concentrations, and C:N ratio on an ash-free basis. Percentage N loss from the clippings after 16 weeks ranged from 88% to 93% at the 0 and 392 kg N ha-1 rates, respectively, and from 86% to 94% when clippings were removed (CRM) or returned (CRT), respectively. Percentage C loss from the clippings ranged from 94% to 95% at the 0 and 392 kg N ha-1 rates, respectively, and from 92% to 96% with CRM and CRT, respectively. Cumulative N release was similar across N fertilization rates, (ranging from 131 g N kg-1 to 135 g N kg-1 tissue) but was higher for CRT (151 g N kg-1 tissue) than for CRM (128 g N kg-1 tissue). Grass clippings decomposed rapidly and released N quickly when returned to the turf thatch layer. This indicates the potential for reduced N fertilization when clippings are returned. Such rapid decomposition also suggests that the contribution of grass clippings to thatch development is negligible.

Grazing rate of microzooplankton measured experimentally in the North Atlantic during the Maria S. Merian cruise MSM26, spring 2013

The microzooplankton grazing dilution experiments were conducted at stations 126, 127, 131 and 133-137, following Landry & Hassett (1982). Seawater samples (whole seawater - WSW) were taken via Niskin bottles mounted on to a CTD Rosette out of the chlorophyll maximum at each station. Four different dilution levels were prepared with WSW and GF/F filtered seawater - 100% WSW, 75% WSW, 50% WSW and 25% WSW. The diluted WSW was filled in 2.4 L polycarbonate bottles (two replicates for every dilution level). Three subsamples (250 - 500 mL depending on in situ chlorophyll) of the 100% WSW were filtered on to GF/F filters (25 mm diameter) and chlorophyll was extracted in 5 mL 96% ethanol for 12-24 hours. Afterwards it was measured fluorometrically before and after the addition of HCl with a Turner fluorometer according to Jespersen and Christoffersen (1987) on board of the ship. In addition, one 250 mL subsample of the 100% WSW was fixed in 2% Lugol (final concentration), to determine the microzooplankton community when back at the Institute for Hydrobiology and Fisheries Science in Hamburg. Also, one 50 mL subsample of the 100% WSW was fixed in 1 mL glutaraldehyde, to quantify bacteria abundance. The 2.4 L bottles were put in black mesh-bags, which reduced incoming radiation to approximately 50% (to minimize chlorophyll bleaching). The bottles were incubated for 24 hours in a tank on deck with flow-through water, to maintain in situ temperature. An additional experiment was carried out to test the effect of temperature on microzooplankton grazing in darkness. Therefore, 100% WSW was incubated in the deck tank and in two temperature control rooms of 5 and 15°C in darkness (two bottles each). The same was done with bottles where copepods were added (five copepods of Calanus finmarchicus in each bottle; males and females were randomly picked and divided onto the bottles). In addition, two 100% WSW bottles with five copepods each were incubated at in situ temperature at 100% light level (without mesh-bags). All experiments were incubated for 24 hours and afterwards two subsamples of each bottle were filtered on to GF/F filters (25 mm diameter); 500 - 1000 mL depending on in situ chlorophyll. One 250 mL subsample of one of the two replicates of each dilution level and each additional experiment (temperature and temperature/copepods) was fixed in 5 mL lugol for microzooplankton determination. One 50 mL subsample of one of the two 100% WSW bottles as well as of one of the additional experiments without copepods was fixed in 1 mL glutaraldehyde for bacteria determination later on. Copepods were fixed in 4% formaldehyde for length measurements and sex determination.

Efecto del estado de madurez y atmósferas modificadas sobre la calidad de cerezas cv. Sweetheart

Se estudió el efecto de cosechar cerezas en dos estados de madurez, así como el uso de atmósferas modificadas empleando PBD y PVC, sobre la calidad de fruta almacenada a 0 °C durante 21 y 42 días, respectivamente. La calidad fue evaluada en base a pérdida de peso (%), color (ángulo hue), firmeza, contenido de sólidos solubles, aspecto de los pedicelos y presencia de podredumbres. La fruta cosechada más madura presentó color, sólidos solubles y firmeza adecuados durante los 21 días a 0 °C, pero el almacenamiento estuvo limitado por la deshidratación de los pedicelos, que mantuvieron aspecto comercial sólo durante una semana. Para ambos estados de madurez, la pérdida de peso fue importante y se registró aumento del contenido de sólidos solubles y firmeza. Sin embargo, la fruta cosechada más inmadura no alcanzó en ningún momento la coloración ni contenido de azúcares de la fruta cosechada en estado de madurez más avanzado. Mediante el uso de las bolsas PBD se logró minimizar la deshidratación y mantener las características organolépticas de la fruta, así como un alto porcentaje de pedicelos con buen aspecto y color durante los 42 días de conservación en frío. El uso de PVC se vio limitado por el deterioro de los pedicelos que afectó alrededor del 50 % de la fruta analizada al término de la primera semana.

Poscosecha de ciruela variedad angeleno : conservación frigorífica tradicional y en atmósfera modificada

Objetivos: reducir pérdidas durante la conservación frigorífica, emplear atmósfera modificada como método suplementario a la refrigeración, alargar el período de aptitud comercial. Metodología: se trabajó con fruta acondicionada a 0±1 °C y 90±5 % HR, según las siguientes variantes: 1. testigo: 20 kg fruta a granel sin seleccionar en caja plástica; 2. granel + film PVC: 10 kg de fruta a granel en bandejas de madera más cartón corrugado recubierta con film de PVC; 3. celpack: bandejas de madera recubiertas de cartón corrugado con dos celpack de 23 frutos cada uno; 4. celpack + atmósfera modificada: ídem anterior pero cada celpack en bolsa de polietileno de baja densidad de 20 μ. A partir de los 30 días de conservación se extrajo semanalmente, durante 9 semanas, una muestra de 46 frutos, de los cuales 23 fueron analizados al momento de ser extraídos y los 23 restantes luego de 48 horas de comercialización simulada (sc). Para la evaluación estadística se aplicó análisis de la varianza con el programa SAS (Statistical Analysis System) y se determinaron las diferencias entre tratamientos con el test de Duncan. Para sabor, en cambio, se aplicó una prueba de homogeneidad de P2. La evaluación de sabor se realizó mediante degustación con panel de 5 catadores entrenados. Resultados: Los frutos tenían las siguientes características al inicio de conservación: calibre 61.4 mm, peso 117.8 g, firmeza de pulpa 3.1 kgf, sabor agridulce, contenido de sólidos solubles 17.5 °Bx, acidez 0.78 g ác. málico%g, % cubrimiento 83.69 %. Luego de la conservación frigorífica (97días): % de color de cobertura 95 %. La firmeza de la pulpa en el tratamiento celpack + bolsa se diferencia con valores más altos, media de 2.8 kgf , el resto con media 2.6 kgf. En sc la firmeza es inferior y esta disminución es menor en celpack + bolsa. Sólidos solubles, media 17.21 °Bx, en sc valores con media de un 0.3 % más. Acidez titulable: disminución progresiva, de 0.68 a 0.47 g%g al fin de conservación. Sabor: a partir de los 59 días aumentan los frutos insípidos y desagradables excepto en celpack + bolsa. Síntomas de deshidratación: a partir de los 79 días la única variante que no presenta síntomas es celpack + bolsa. Conclusiones: El acondicionamiento en celpack redujo la incidencia de ataque por mohos (fue el único tratamiento sin ataque durante 94 días); tampoco presentó sabores desagradables y su limitación en conservación se debió a la deshidratación evidente a partir de 74 días. La fruta embalada en celpack + bolsa tuvo mayores valores de resistencia a la presión y 100 % de frutos sin deshidratación a los 94 días de conservación; a partir de 80 días es evidente el ataque de mohos y frutos con sabores desagradables. Las variantes granel y granel + film presentan deterioro por deshidratación a partir de 74 días. La conservación no debería superar 80 días. Celpack + bolsa muestra mejores resultados, con mayores valores de resistencia a la presión que los otros tratamientos; con respecto al sabor, mantiene una mayor proporción de sabor dulce.

Oxygen contents, sulfate concentrations, and changes of IPLs under different storage conditions of samples from ODP Leg 204 and IODP Expedition 311

We have studied the effects of slow infiltration of oxygen on microbial communities in refrigerated legacy samples from ocean drilling expeditions. Storage was in heat-sealed, laminated foil bags with a N2 headspace for geomicrobiological studies. Analysis of microbial lipids suggests that Bacteria were barely detectable in situ but increased remarkably during storage. Detailed molecular examination of a methane-rich sediment horizon showed that refrigeration triggered selective growth of ANME-2 archaea and a drastic change in the bacterial community. Subsequent enrichment targeting methanogens yielded exclusively methylotrophs, which were probably selected for by high sulfate levels caused by oxidation of reduced sulfur species. We provide recommendations for sample storage in future ocean drilling expeditions.

Biogeochemistry measurements in a mesocosm experiment in the Bay of Hopavagen, Norway, in August 2012

The goal of this work has been to examine the influence of upper ocean food web structure and functioning on both the natural and artificially enhanced sequestration of carbon within the ocean. Data obtained in the mesocosm experiment run in the Bay of Hopavågen in August 2012 are used to assess the extent to which organic matter produced within four different food webs is retained in the upper ocean food web versus remineralized back to carbon dioxide and inorganic nutrients (ammonium, dissolved silicon, phosphate) versus exported from the system in the form of rapidly sinking particles. The experiment was carried out in a set of 12 mesocosms covering, in triplicate, 2 different phytoplankton communities (diatom versus non-diatom) exposed to 2 different zooplankton communities (-copepod and +copepod). These starting conditions were established by first filling the bags, roughly simultaneously, with seawater from the Bay of Hopavågen. Mesozooplankton were then removed to the most complete extent possible immediately removed from half of the mesocosms through repeated vertical hauls of a plankton net (200 µm mesh). Nitrate and phosphate was added to half mesocosms daily to promote the growth of non-siliceous phytoplankton (e.g. dinoflagellates or coccolithophores). To the other half of the mesocosms, nitrate, phosphate, and silicate were added to promote the growth of diatoms. Material was allowed to settle and the two distinct phytoplankton populations were allowed to develop for 4 days, after which copepods collected from the Bay of Hopavågen were added back to the half of the N+P mesocosms and to the half of the N+P+Si mesocosms from which mesozooplankton had not been removed at the beginning. This yielded a set of four initial starting conditions (N+P-copepods, N+P+copepods, N+P+Si-copepods, and N+P+Si+copepods). In the primary mesocosms, samples for a set of core parameters were taken every time the mesocosms were sampled. Samples for particulates (PIC, BSi, POC, PON) were collected on GF/F or 0.4 µm polycarbonate.

Mesocosm experiment Cape Verde 2012: Data

Two 7-day mesocosm experiments were conducted in October 2012 at the Instituto Nacional de Desenvolvimento das Pescas (INDP), Mindelo, Cape Verde. Surface water was collected at night before the start of the respective experiment with RV Islândia south of São Vicente (16°44.4'N, 25°09.4'W) and transported to shore using four 600L food safe intermediate bulk containers. Sixteen mesocosm bags were distributed in four flow-through water baths and shaded with blue, transparent lids to approximately 20% of surface irradiation. Mesocosm bags were filled from the containers by gravity, using a submerged hose to minimize bubbles. The accurate volume inside the individual bags was calculated after addition of 1.5 mmol silicate and measuring the resulting silicate concentration. The volume ranged from 105.5 to 145 L. The experimental manipulation comprised addition of different amounts of inorganic N and P. In the first experiment, the P supply was changed at constant N supply in thirteen of the sixteen units, while in the second experiment the N supply was changed at constant P supply in twelve of the sixteen units. In addition to this, "cornerpoints" were chosen that were repeated during both experiments. Four cornerpoints should have been repeated, but setting the nutrient levels in one mesocosm was not succesfull and therefore this mesocosm also was set at the center point conditions. Experimental treatments were evenly distributed between the four water baths. Initial sampling of the mesocosms on day 1 of each run was conducted between 9:45 and 11:30. After nutrient manipulation, sampling was conducted on a daily basis between 09:00 and 10:30 for days 2 to 8.

Full scale test for explosion water barriers in small cross-section galleries

Underground coal mines explosions generally arise from the inflammation of a methane/air mixture. This explosion can also generate a subsequent coal dust explosion. Traditionally such explosions have being fought eliminating one or several of the factors needed by the explosion to take place. Although several preventive measures are taken to prevent explosions, other measures should be considered to reduce the effects or even to extinguish the flame front. Unlike other protection methods that remove one or two of the explosion triangle elements, namely; the ignition source, the oxidizing agent and the fuel, explosion barriers removes all of them: reduces the quantity of coal in suspension, cools the flame front and the steam generated by vaporization removes the oxygen present in the flame. Passive water barriers are autonomous protection systems against explosions that reduce to a satisfactory safety level the effects of methane and/or flammable dust explosions. The barriers are activated by the pressure wave provoked in the explosion destroying the barrier troughs and producing a uniform dispersion of the extinguishing agent throughout the gallery section in quantity enough to extinguish the explosion flame. Full scale tests have been carried out in Polish Barbara experimental mine at GIG Central Mining Institute in order to determine the requirements and the optimal installation conditions of these devices for small sections galleries which are very frequent in the Spanish coal mines. Full scale tests results have been analyzed to understand the explosion timing and development, in order to assess on the use of water barriers in the typical small crosssection Spanish galleries. Several arrangements of water barriers have been designed and tested to verify the effectiveness of the explosion suppression in each case. The results obtained demonstrate the efficiency of the water barriers in stopping the flame front even with smaller amounts of water than those established by the European standard. According to the tests realized, water barriers activation times are between 0.52 s and 0.78 s and the flame propagation speed are between 75 m/s and 80 m/s. The maximum pressures (Pmax) obtained in the full scale tests have varied between 0.2 bar and 1.8 bar. Passive barriers protect effectively against the spread of the flame but cannot be used as a safeguard of the gallery between the ignition source and the first row of water troughs or bags, or even after them, as the pressure could remain high after them even if the flame front has been extinguished.
