To describe, at high resolution, the bacterial population dynamics and chemical transformations during ensiling of alfalfa subsequent exposure to air. Samples alfalfa, ensiled silage exposed air were collected their structures compared using 16S rRNA gene libraries containing approximately 1900 sequences each. Cultural analyses also performed complement sequence data. Sequence analysis revealed significant differences (P < 0·05) in populations each time point. The alfalfa‐derived library...
Silage, fermented cattle feed, has recently been identified as a significant source of volatile organic compounds (VOCs) to the atmosphere. A small number studies have measured VOC emission from silage, but not enough is known about processes involved accurately quantify rates and identify practices that could reduce emissions. Through literature review, we focused on identifying most important emitted corn silage (the common type in US) sources these by quantifying their production...
Com objetivo de avaliar o efeito da aplicação piraclostrobina em variáveis fisiológicas e fenométricas cultura soja, realizou-se um experimento campo entre novembro 2005 maio 2006. Foram realizadas avaliações taxa fotossintética respiração. Também foi avaliada a atividade enzima nitrato redutase, massa mil grãos produtividade. O delineamento experimental blocos ao acaso com três tratamentos (T1 - sem fungicida, T2 duas aplicações T3 tebuconazol triazol) quatro repetições. A ocasionou...
California is the leading dairy state in United States. The total sale of milk and its products represents about $6.3 billion annually out $50 generated from all agricultural production state. However, methane emissions manure enteric fermentation represented nearly half annual California, with accounting for 25%, 20%. Methane originating are produced primarily anaerobic settling basins lagoons, which most common storage systems To achieve sustainability on farms to comply regulations air...
Application of municipal biosolids in agriculture present a concern with potential uptake and bioaccumulation pharmaceutical compounds from into agronomic plants. We evaluated the efficacy biochar as soil amendment to minimize antimicrobial agents (ciprofloxacin, triclocarban, triclosan) lettuce (Lactuca sativa) carrot (Daucus carota) Biochar reduced concentration ciprofloxacin triclocarban leaves resulted 67% reduction triclosan roots. There was no substantial difference concentrations...
Agricultural soils are important sources of atmospheric N2O and CO2. However, in boreal agro-ecosystems the contribution winter season to annual emissions these gases has rarely been determined. In this study, soil CO2 fluxes were measured for 6 years a corn-soybean-wheat rotation northeast China quantify wintertime emissions. The treatments chemical fertilizer (NPK), plus composted pig manure (NPKOM), control (Cont.). Mean among all three (November-March), when temperatures below -7°C...
Due to the increase of water deficiency in many farm regions and its meaning on weed interference, competitive interactions between soybean three weeds were evaluated under stress (20 40 days after transplanting) no conditions. Three independent experiments carried out a growth chamber, being each one composed by Alternanthera tenella, Tridax procumbens or Digitaria ciliaris, along with crop, which soil condition plant composition effects while competition. A replacement series system was...
