<P>The third generation of the Sloan Digital Sky Survey (SDSS-III) took data from 2008 to 2014 using the original SDSS wide-field imager, the original and an upgraded multi-object fiber-fed optical spectrograph, a new near-infrared high-resolution spectrograph, and a novel optical interferometer. All of the data from SDSS-III are now made public. In particular, this paper describes Data Release 11 (DR11) including all data acquired through 2013 July, and Data Release 12 (DR12) adding data acquired through 2014 July (including all data included in previous data releases), marking the end of SDSS-III observing. Relative to our previous public release (DR10), DR12 adds one million new spectra of galaxies and quasars from the Baryon Oscillation Spectroscopic Survey (BOSS) over an additional 3000 deg(2) of sky, more than triples the number of H-band spectra of stars as part of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE), and includes repeated accurate radial velocity measurements of 5500 stars from the Multi-object APO Radial Velocity Exoplanet Large-area Survey (MARVELS). The APOGEE outputs now include the measured abundances of 15 different elements for each star. In total, SDSS-III added 5200 deg(2) of ugriz imaging; 155,520 spectra of 138,099 stars as part of the Sloan Exploration of Galactic Understanding and Evolution 2 (SEGUE-2) survey; 2,497,484 BOSS spectra of 1,372,737 galaxies, 294,512 quasars, and 247,216 stars over 9376 deg(2); 618,080 APOGEE spectra of 156,593 stars; and 197,040 MARVELS spectra of 5513 stars. Since its first light in 1998, SDSS has imaged over 1/3 of the Celestial sphere in five bands and obtained over five million astronomical spectra.</P>

Amendments and Construction Systems for Improving the Performance of Sand-Based Putting Greens

Putting green을 골프장 전체 면적의 $2\%$로 작은 면적이지만 green의 건강한 상태는 골프장의 성공여부를 좌우한다. 이 실험은 University of Missouri-Columbia, Turfgrass Research Center에서 어느 putting green root zone 구조와 토양 개량제가 가장 건강하고 최적의 putting green조건을 유지하는가를 비교하기 위하여 1999년 6월부터 2002년 12월까지 실행되어졌다. California putting green root zone system(30츠의 $100\%$ 모래층 밑에 13cm silt loam 토양층)은 특히 putting green을 가격을 줄일 수 있으며 배수가 잘되고 공기 순환에 있어서는 좋은 조건이지만 낮은 수분 보존량과 잔디에 공급되어지는 영양분이 낮은 것으로 조사 되어지고 있다. USGA(United States Golf Association) putting green root zone system [30cm의 $90\%$ 모래와 $10\%$ Peatmoss (organic material; 유기물) 혼합물층 밑에 13cm 자갈층]은 California system($100\%$ 모래)의 단점을 보완할 수 있지만 년수가 지남에 따라 문제점이 발견되어졌다. 시간의 흐름에 따른 organic matter의 축적과 분해 그리고 잦은 잔디관리 장비의 운행과 player들의 발자국에 의한 green compaction(압축)의 증가가 putting green에서의 수분 침투량(Infiltration rate)과 공기순환을 방해하며 이로인해 잔디의 생장을 저해하며 green의 질은 낮게 만든다. Putting green root zone mixtures에서의 유기물질인 peatmoss사용에 비해 Zeolite와 같은 무기물질의 사용이 토양 물리적, 생리적 특성에 있어 우수함이 조사되어지고 있다. 년수가 지날수록 증가하는 USGA green($10\%$ Peatmoss)의 단점 (organic matter의 축적과 분해 증가, 수분 침투력과 공기순환 감소, 높은 수분함량)에 비해 $10-15\%$ Zeolite(무기물)의 사용이 보다나은 putting green 물리적, 생리적 조건들을 오래토록 유지할 수 있으며 건강한 잔디상태를 보존할 수 있을 것이다. 이 시험은 수정된 Modified California putting green root zone system [25cm의 $85\%$ 모래와 $15\%$ Zeolite(inorganic material ; 무기물) 혼합물층 밑에 18cm silt loam 토양층]이 California와 USGA green system과 비교할 때 보다나은 putting green 조건을 유지하는가를 위해 조사되어졌다. 수정된 Modified California green system이 건강한 putting green을 유지하기 위한 우수한 물리적 조건(높은 수분 침투력과 수분 함량, 낮은 토양밀도)과 생리적 조건(높은 양이온 교환력과 유효 식물영양분 함량)을 가지고 있음이 조사되어졌다. 또한 우수한 putting green 잔디품질을 이 실험 기간동안 유지하였다. 결론적으로 California system($100\%$ 모래)에 $15\%$의 무기물질(Zeolite)이 첨가되어진 Modified California putting green system이 최적의 putting green 조건과 우수한 Bentgrass 잔디품질을 4년 동안 유지하였음을 이 실험을 통해 조사되어졌다. Physical and chemical properties of root zone mixes and methods of green construction are important considerations for improving turf grass quality for putting greens. This study compared Penncross creeping bentgrass (Agrostis palustris Huds.) performance as affected by three root zone construction systems with three amendments (sand, peat, and zeolite). The objective of this study was to determine if an amended California construction system would improve green performance during establishment (1998-1999) and maturation (2000-2001). Three treatments were tested: California ($100\%$ sand), USGA($90\%$ sand and $10\%$ peat, v/v), and California-Z ($85\%$ sand and $15\%$ zeolite, v/v). Treatments were arranged in a randomized complete block with four replicates. Physical and chemical properties of the root zone and bentgrass performance were compared for the treatments. The California-Z treatment had the highest saturated hydraulic conductivity, field infiltration rate and the lowest bulk density. It also had the highest cation exchange capacity and plant available nutrient concentrations among the three treatments. The California-Z treatment produced bentgrass quality and color during green establishment and maturation that were equal to or higher than the California treatment, and consistently higher than the USGA treatment. The addition of an inorganic amendment to the California system improved physical and chemical properties of the root zone and improved quality and color of bentgrass during green establishment. During green maturation, creeping bentgrass in the California-Z treatment was equal (6 of 15 sampling dates) or $20\%$ higher (9 of 15 dates) in quality compared to the California system.

Phosphorus and Nitrogen Sorption to Soils in the Presence of Poultry Litter-Derived Dissolved Organic Matter

Goyne, Keith W.,Jun, Hee-Joong,Anderson, Stephen H.,Motavalli, Peter P. Wiley (John WileySons) 2008 Journal of environmental quality Vol.37 No.1

<P>Two environmental aspects associated with land application of poultry litter that have not been comprehensively evaluated are (i) the competition of dissolved organic matter (DOM) and P for soil sorption sites, and (ii) the sorption of dissolved organic nitrogen (DON) relative to inorganic nitrogen species (e.g., NO(3)(-) and NH(4)(+)) and dissolved organic carbon (DOC). The competition between DOM and P for sorption sites has often been assumed to increase the amount of P available for plant growth; however, elevating DOM concentrations may also increase P available for transport to water resources. Batch sorption experiments were conducted to (i) evaluate soil properties governing P sorption to benchmark soils of Southwestern Missouri, (ii) elucidate the impact of poultry litter-derived DOM on P sorption, and (iii) investigate DON retention relative to inorganic N species and DOC. Soils were reacted for 24 h with inorganic P (0-60 mg L(-1)) in the presence and absence of DOM (145 mg C L(-1)) using a background electrolyte solution comparable to DOM extracts (I = 10.8 mmol L(-1); pH 7.7). Soil P sorption was positively correlated with metal oxide (r(2) = 0.70) and clay content (r(2) = 0.79) and negatively correlated with Bray-1 extractable P (r(2) = 0.79). Poultry litter-derived DOM had no significant negative impact on P sorption. Dissolved organic nitrogen was preferentially removed from solution relative to (NO(3)(-)-N + NO(2)(-)-N), NH(4)(+)-N, and DOC. This research indicates that poultry litter-derived DOM is not likely to enhance inorganic P transport which contradicts the assumption that DOM released from organic wastes increases plant-available P when organic amendments and fertilizer P are co-applied. Additionally, this work demonstrates the need to further evaluate the fate and transport of DON in agroecosystem soils receiving poultry litter applications.</P>
