Pełny tekst źródłaIncreased nitrogen (N) fertilizer additions to modern agricultural cropping systems will be necessary to feed a growing world population. However, greater nitrogen use efficiency (NUE) is required if agroecosystems are to continue to provide certain ecosystem services (e.g., greenhouse gas emission reductions and water quality goals). The aim of this research was to investigate the role of variable rate N and seeding of winter wheat (Triticum aestivum) for optimizing yield-water-NUE relationships across heterogeneous landscapes. Field plot studies were conducted at the Cook Agronomy Farm (CAF) near Pullman, WA during the 2010, 2011 and 2012 winter wheat harvest years. A randomized complete block split plot N rate x seeding rate experiment with N fertilizer rate as main plot and seeding rate as subplot was employed across three landscape positions. Assessed were evidence of “haying-off”, depletion of available water resources, and the link between yield, protein, and NUE response to landscape by N fertilization rate by seeding rate treatment combinations. A performance classification was developed to evaluate wheat performance with regard to N utilization efficiency (Gw/Nt) and N uptake efficiency (Nt/Ns) components of the NUE.
Evidence of haying-off in winter wheat was medium to high for drier landscape positions, particularly during low precipitation years and likely occurs in these landscapes most years. Treatment impacts on NUE varied by year and landscape but overall NUE decreased by 14 to 22 kg grain yield per kg N supply as N rate increased from 0 to 160 kg N ha-1 across three landscape positions and two site years (2011 and 2012). Target NUE and maximum anthesis biomass could be achieved with a 34 to 68% reduction in typical seeding rates. The NUE-based performance classification was helpful in identifying environmental or management conditions contributing to low or high NUE indicating potential to be used as an evaluation tool. This research also included a policy fellowship focused on N2O emission reductions and greenhouse gas offset credits that could be generated from adoption of variable rate N for wheat and concluded that offset credits alone would not provide enough incentive for adoption of variable rate N.

Com objetivo de validar o uso no campo do coletor de espuma com ácido e politetrafluoroetileno que capta amônia volatilizada e quantificar essa perda oriunda de fontes e formas de aplicação de nitrogênio (N) em pastagens, realizou-se 2 experimentos. No experimento 1, para avaliação do coletor, utilizou-se fatorial 2 x 2 - doses de N (50 e 100 kg/ha) e coletores de amônia (coletor semi-aberto e absorvedor de espuma com ácido e politretafluoroetileno). O período experimental foi de 22 dias. No experimento 2 utilizou-se delineamento de blocos ao acaso e os tratamentos foram: uréia; Super N®; uréia + 12,5% de zeólita; uréia + 25% de zeólita; uréia + 50% de zeólita; uréia em pulverização foliar; 75% de uréia + 25% de sulfato de amônio; nitrato de amônio e sem N (testemunha). A avaliação das perdas por volatilização de amônia ocorreu em 3 épocas. No verão/07 e inverno/07 utilizou-se dose de 50 kg/ha de N para adubos sólidos e 15 kg/ha de N para pulverização foliar e para o verão/08 as doses foram duplicadas. As perdas diárias de amônia foram avaliadas em onze amostragens a cada dois dias para ambos os experimentos. Para o experimento 1, não houve diferença entre os coletores na perda acumulada e diária de amônia com a dose de 50 kg/ha de N. Entretanto, na dose de 100 kg/ha de N o coletor semi-aberto captou o maior pico de volatilização diária e maior acúmulo de amônia. No experimento 2 as menores perdas por volatilização foram detectadas para nitrato de amônio aplicado a lanço e uréia via pulverização foliar. Dessa forma poderia ocorrer melhor uso do fertilizante pela planta refletindo em aumento na produção e qualidade da forragem.
With the objective of validating the field use of the foam collector with acid and polytetrafluorethylene, which captures volatilized ammonia and quantify this loss when using sources and application forms of nitrogen (N) in pastures, 2 experiments were realized. In the experiment 1, to evaluate the collector a 2 x 2 factorial – N doses (50 and 100 kg/ha) and ammonia collectors (semi-open collector and foam absorber with acid and polytetrafluorethylene). The experimental period was 22 days. In the experiment 2, the experimental design was a randomized block design and the treatments were: urea; Super N®; urea + 12,5% of zeolite; urea + 25% of zeolite; urea + 50% of zeolite; urea leaf spraying, 75% of urea + 25% of ammonium sulfate, ammonium nitrate, and without nitrogen (control). The evaluation of the volatilization losses occurred in 3 periods. On summer/07 and winter/2007 a 50 kg/ha of N dose for solid fertilizers was used and a 15 kg/ha N dose for leaf spraying and on summer/2008 the doses were doubled. The daily losses of ammonia were evaluated in eleven samplings every two days for both experiments. In the experiment 1, there was no difference between the collectors in the accumulated and daily loss in the dose of 50kg/ha of N. However, with the dose of 100 kg/ha of N the semi-open collector showed the highest peak of daily volatilization and accumulated the highest volatilization loss. In the experiment 2, the lowest volatilization losses were detected for ammonium nitrate in soil application and urea in leaf spraying application. So, in this cases might happen the better use of the fertilizer by the plant, reflecting in the increase of the forage production and quality.

Resumo: Uma consequência da toxicidade de amônio (NH4+) é a diminuição do conteúdo de citocininas (CKs). Dessa forma, o fornecimento de CK, na forma de trans-zeatina (tZ), pode aliviar a toxicidade de NH4+, e a CK sintética 6-benziladenina (BA), de menor custo, ainda não foi estudada quanto ao seu efeito sobre a toxicidade de NH4+. Além disso, o silício (Si), que é um elemento benéfico, é capaz de amenizar vários estresses, como a toxicidade de NH4+. Objetivou-se verificar se o alívio da toxicidade de NH4+ com o uso do Si é dependente do aumento do teor de CKs no tomateiro cv Micro-Tom (MT), os efeitos do Si no tomateiro transgênico MT CKX2 (baixo teor de CKs) submetido à toxicidade de NH4+ e se o regulador de crescimento BA alivia a toxicidade de NH4+ no tomateiro MT. Para isso, realizaram-se cinco experimentos em tomateiro, com a aplicação dos tratamentos na solução nutritiva. No experimento com concentrações de NH4+ entre 1,25 e 7,5 mmol L-1, 5,9 mmol L-1 provocou a toxicidade de NH4+, com diminiução de 10% na massa seca da parte aérea. No experimento com concentrações de Si entre 0,2 e 0,8 mmol L-1, na forma de silicato de potássio (SiK) ou ácido silícico estabilizado (ASiE), a toxicidade de NH4+ não foi aliviada. No experimento com concentrações de Si entre 1,0 e 2,5 mmol L-1, na forma de SiK, a concentração de 1,29 mmol L-1 de Si aliviou a toxicidade de NH4+. No experimento com N nas formas de NO3- ou NH4+ (5,9 mmol L-1), na ausência e na presença de Si (1,29 mmol L-1) no tomat... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: A consequence of ammonium (NH4+) toxicity is the decrease in cytokinins (CKs) content. However, the supply of CK in the nutrient solution, in trans-zeatin (tZ) form, can alleviate NH4+ toxicity, and CK synthetic 6-benzyladenine (BA), with lower cost, has not yet been studied on the NH4+ toxicity. Similarly, silicon (Si), which is a beneficial element known to relieve stresses, also alleviates NH4+ toxicity. The objective was to verify if the relief of NH4+ toxicity by Si is dependent on the increase of the CKs content in tomato cv Micro-Tom (MT), the effects of Si on the transgenic tomato MT CKX2 (CKs deficient) submitted to NH4+ toxicity, and if the growth regulator 6-benzyladenine (BA) alleviates NH4+ toxicity in tomato MT. For this, five experiments were carried in tomato, with treatments application in nutrient solution. In experiment with NH4+ concentrations between 1.25 and 7.5 mmol L-1, 5.9 mmol L-1 caused NH4+ toxicity, with shoot dry weight 10% decrease. In experiment with Si concentrations between 0.2 and 0.8 mmol L-1, via potassium silicate (SiK) or stabilized silicic acid (ASiE), NH4+ toxicity was not alleviated. In the experiment with Si concentrations between 1 and 2.5 mmol L-1, via SiK, the concentration of 1.29 mmol L-1 alleviated NH4+ toxicity. In experiment with N in NO3- or NH4+ forms (5.9 mmol L-1), in absence and presence of Si (1.29 mmol L-1) in MT tomato, Si decreased CKs content in root and increase in shoot, independent of the N form. In same experime... (Complete abstract click electronic access below)

Pełny tekst źródłaKvävgas i form av N2 finns i överflöd i jordens atmosfär. Cirka 78% av luften är i själva verket N2. För att levande organismer ska kunna använda det atmosfäriska kvävet måste den först brytas ned och bindas till antingen väte, kol eller syre. I sin reaktiva form fungerar elementet som en grundläggande byggsten för alla levande varelser. Den naturliga processen som förvandlar oanvändbart atmosfäriskt kväve till dess reaktiva former kallas kvävefixering och utförs av bakterier. I ekosystemet avgör därmed tillgängligheten av reaktivt kväve vegetationens tillväxt och är därmed en begränsande faktor för jordbruket. Denna begränsning upphörde med uppfinningen av industriell kvävefixering i form av Haber-Bosch processen där ammoniak utvinns ur luften. Sedan dess har miljontals ton av reaktivt kväve införts till den naturliga kvävecykeln och orsakat störningar med allvarliga konsekvenser. I Sverige började arbetet med att reducera överskottet av reaktivt kväve på allvar under 1980-talet då näringsinnehållet i Östersjön redan hade överskridit hållbara nivåer. Sedan dess har ny lagstiftning som behandlar frågan införts både på nationell nivå och på EU- nivå. Insatserna har påverkat minskningen av kväveöverskottet, men många belastningsgränser överskrids fortfarande. För att samordna strategier och lagstiftning kring den komplexa kvävecykeln och ytterligare begränsa miljöbelastningen krävs en mer integrerad, holistisk strategi och ett gemensamt ramverk. Denna studie skapades med detta i åtanke och med målet att öka medvetenheten om kvävets belastning på miljön. I studien kvantifierades mänskligt inducerade källor och mekanismer associerade med kväve och illustrerades i flera diagram konstruerade med en materialflödesanalys (MFA) metod. Det svenska samhället är indelat i fyra sektorer: jordbruk, industri, konsumtion och avfallshantering. De resulterande kväveflödena används sedan för att lyfta fram intressanta områden och skapa en översiktsbild. Resultaten visar betydande flöden som huvudsakligen härrör från livsmedelssystemet, med början i jordbruksanvändning av mineral- och organisk gödselmedel. Utsläpp av ammoniak till luft från djurhållning samt läckage av kväve till vattendrag utgör de största förlusterna i jordbrukssektorn. Den drivande kraften bakom det stora inflödet av gödselmedel och orsaken till jordbruksförlusterna är först och främst hushållens konsumtionsmönster. Utsläpp av kväveoxider från trafik och industriprocesser utgör även en stor del den totala kvävebelastningen. Återvinningsgraden av näringsämnen som slutligen hamnar i avfallssektorn är relativt låg och majoriteten av kvävet denitrifieras i reningsverk. Slutsatsen är att det nuvarande tillståndet för antropogent kväveflöde i Sverige är linjärt och att nytt kväve kontinuerligt måste tillföras till systemet.
