“…In the city of São Paulo, for example, atmospheric deposition decreased twenty-fold from 1985 to 2009 [of 282 to 14 kg ha -1 yr -1 S (Vieira-Filho et al, 2015)]. In cities distant from large industrial centers and the sea, such as Santa Maria (in the state of Rio Grande do Sul), S was atmospherically deposited at rates ranging from 3.2 to 4.5 kg ha -1 yr -1 over the periods (Osório Filho et al, 2007Tiecher et al, 2013).…”

“…Consequently, S is one of the least studied macronutrients in Brazil (Divito et al, 2015;CQFS-RS/SC, 2016) and also in other regions of world (Kihara et al, 2017;Salvagiotti et al, 2017). However, the likelihood of a positive response of grain crops to S fertilization has increased in various ecosystems around the world (Rheinheimer et al, 2005;Ercoli et al, 2011;Blum et al, 2013;Divito et al, 2015;Salvagiotti et al, 2017) as a consequence of (a) higher crop yield potential increasing S plant requirements (Salvagiotti et al, 2017), (b) the repeated use of phosphate and nitrogen fertilizers containing little or no S (Rheinheimer et al, 2005;Osório Filho et al, 2007), (c) reduced S atmospheric deposition (Divito et al, 2015;Vieira-Filho et al, 2015), (d) increased use of monocultures or crop successions, resulting in low inputs of crop residues, and (e) chemical and/or physical constraints on deep-rooting under NT (Dalla Nora et al, 2017). Crop responses to S application in Brazilian NT soils are highly variable and range from substantial increases (Miranda and Miranda, 2008;Fiorini et al, 2016;Pereira et al, 2016;Lopes et al, 2017;Nascente et al, 2017) to slight reductions in grain yield (Barbosa Filho et al, 2005;Megda et al, 2009;Gelain et al, 2011;Rampim et al, 2011) depending on the particular crop, soil, and climate conditions.…”

Sulfur (S) fertilization recommendations for grain crops in Brazil were formerly established from studies on crops with a low yield potential grown on soils under conventional tillage (CT). However, the subsequent adoption of no-tillage (NT) altered S dynamics in the soil, making it necessary to carefully evaluate the applicability of these S fertilizer recommendations. In addition, the emergence of modern high-yield-potential genotypes, the successive application of concentrated low-sulfur fertilizers, and reduction in S atmospheric deposition have raised the likelihood of positive responses of crops to S fertilization. Available literature reports contrasting crop responses to S fertilization in Brazilian soils, ranging from substantial gains to slight yield losses depending on the particular crop, soil, and climate. The primary aim of this study was to examine available data for crop grain responses to S application in NT soils in order to ascertain whether existing recommendations established for Brazilian CT soils also hold for NT soils. A systematic review of data from 35 scientific publications spanning 58 crop harvests revealed a positive yield response to S fertilization in 31 % of the crop harvests, with an average yield increase of 16 %. Crops on soils with available SO 4 2--S contents above the critical level (viz., 7.5 mg dm -3 ) exhibited no positive response to S fertilization in any crop harvest (n = 18). Dry edible bean and corn were the most responsive crops, and canola and wheat, the least. For the trials with positive crop responses, a fertilizer rate of 26 kg ha -1 S sufficed to obtain at least 95 % of the maximum possible yield. In general, the S fertilization recommendations previously established for CT soil proved effective with grain crops on NT soils as a result of the critical levels of soil available SO 4 2--S and the fact that the recommended S rates are similar to those found in this study considering trials conducted under NT conditions only. However, existing recommendations could be improved by using additional criteria for soils with available SO 4 2--S contents below the critical level since a positive response was observed in 22 % (n = 18) and 92 % (n = 12) of the crop harvests under a subtropical and a tropical climate, respectively. Our results suggest that S fertilization must be prioritized in NT soils with available SO 4 2--S contents below 7.5 mg dm -3 in the 0.00-0.20 m layer, especially in tropical climate zones. In addition, regional fertilizer recommendation guidelines should consider crop type and yield expectation in order to facilitate more sustainable S management and increased crop yields in Brazil.

“…For that and other reasons, differently from N, sulfur fertilization has been little explored in relation to other nutrients, inspite of its importance as a plant nutrient . However, the intensive cultivation of soils with low levels of organic matter, as for instance, the soils of the Brazilian Cerrado region, and in addition to the use of NPK fertilizers, poor in S can lead to the reduction of the availability of that nutrient for the plants, resulting in the decrease in crop production (Fernandes et al, 2007;Osório Filho et al, 2007;Rezende et al, 2009). The cotton plant requires a continuous S supply during its growth cycle and, low fertility soils, respond well to the application of that nutrient (Silva et al, 1981;Staut & Kurihara, 2001).…”

The Brazilian Savanna (Cerrado) ecosystem concentrates most of the area under cotton cultivation in the country, and is characterized, predominantly, by low fertility soils. Nitrogen (N) is the most extracted nutrient from the soil by most crops, while sulfur (S) fertilization has been little explored in studies with cotton plants. This study aimed to evaluate the effects of N and S fertilization on the N content of leaf, weight of 30 bolls, productivity, and agronomic efficiency of cotton plants grown in an Oxisol from the Brazilian Cerrado region. Two independent field experiments were carried out simultaneously in a completely randomized block design with four replications. The first experiment was composed of five levels of N (17, 100, 150, 200 and 250 kg ha -1 ) and the second with five levels of S (24, 50, 75, 100 and 125 kg ha -1 ). The leaf N content of the cotton plants increased linearly with the supply of up to 250 kg ha -1 of N in the soil. The weight of 30 bolls and the seed-cotton productivity were considerably increased with the increase of the N and S levels in the soil. The maximum agronomic efficiency of the N and S fertilization was obtained with the application of 150 and 100 kg ha -1 of N and S, respectively. Therefore, this study clearly showed the positive effects of the adequate fertilization of N and S on the productivity of cotton in soils from the Brazilian Cerrado region.Key words: boll, fertilization, Gossypium hirsutum, leaf content, low fertility soil Produtividade e eficiência agronômica do algodoeiro em resposta ao suprimento de nitrogênio e enxofre RESUMO A região de Cerrado do Brasil, onde se concentra a maior parte da área de algodão plantada no País, possui, predominantemente, solos de baixa fertilidade. O nitrogênio (N) é o nutriente mais extraído do solo pela maioria das culturas enquanto a adubação com enxofre (S) tem sido pouco explorada em estudos com algodoeiro. O objetivo deste estudo foi avaliar os efeitos da adubação nitrogenada e sulfatada sobre o teor foliar de nitrogênio, peso de 30 capulhos, produtividade e eficiência agronômica, em algodoeiro cultivado em um Latossolo da região de Cerrado Brasileiro. Dois experimentos de campo, independentes, foram conduzidos simultaneamente em delineamento em blocos completos casualizados, com quatro repetições, em que o primeiro experimento foi composto por cinco níveis de N (17, 100, 150, 200 e 250 kg ha ). O teor de N nas folhas do algodoeiro aumentou de forma linear com o fornecimento de até 250 kg ha -1 de N no solo. O peso de 30 capulhos e a produtividade de algodão em caroço foram incrementados consideravelmente com o acréscimo dos níveis de N e S no solo. A máxima eficiência agronômica das adubações nitrogenada e sulfatada foi obtida com a aplicação de 150 e 100 kg ha -1 de N e S, respectivamente. Este estudo mostrou claramente os efeitos positivos da fertilização adequada de N e S sobre a produtividade do algodoeiro em solos da região de Cerrado do Brasil.Palavras-chave: capulho, fertilização, Gossypium hirsutu...

“…Fertilizantes com baixa concentração de NPK tendem a conter, em grandes quantidades, como fonte de P, o superfosfato simples, o que aumenta o teor de S. Fórmulas mais concentradas em NPK tendem a conter como fontes de P o monoamônio fosfato (MAP), diamônio fosfato (DAP) e o superfosfato triplo, que têm baixas concentrações de S (Stipp & Casarin, 2010). Desta forma, o uso de fertilizantes concentrados com ausência de S, associados às exportações deste elemento pelas colheitas reduzem a disponibilidade de S no solo (Osório Filho et al, 2007), aumentando a probabilidade de resposta das culturas à adubação sulfatada.…”

RESUMOO manejo da fertilização interfere na eficiência dos fertilizantes e a adoção de diferentes métodos de aplicação deve contemplar o aspecto operacional, agronômico e econômico. O estudo tem como objetivo avaliar a eficiência de fontes de fertilizantes e de métodos de aplicação na cultura da soja. O experimento foi conduzido nos anos agrícolas 2012/2013 e 2013/2014, num Latossolo Vermelho Distrófico, em Cruz Alta, RS. Os tratamentos foram constituídos de quatro fontes de fertilizantes e dois métodos de aplicação, no delineamento experimental em blocos ao acaso com os tratamentos em arranjo fatorial com quatro repetições. As fontes fertilizantes são: MicroEssentials ® S9 puro (09.46.00); MicroEssentials® S9 misturado a outras matérias primas (07.34.12); Fosfato Monoamônico (MAP); Fórmula 00.20.20, sendo as doses ajustadas de maneira a ser mantida a mesma relação nutricional em 92 kg ha -1 para P 2 O 5 e K 2 O, com a utilização de KCl (00.00.60) a lanço. As diferentes fontes foram aplicadas à lanço na superfície do solo e na linha de semeadura. A maior produtividade de soja está associada tanto à utilização de MicroEssentials ® S9 07.34.12 na linha de semeadura ou à lanço na superfície. A menor produtividade de grãos de soja está associada à utilização da Fórmula 00.20.20, quando aplicados na linha de semeadura. Houve efeito residual das fontes de fertilizantes aplicadas somente para os teores de enxofre no solo. Palavras-chave: adubação, Glycine max, nutrição vegetal Implementation methods and sources of fertilizers of the soybean crop ABSTRACTThe management of fertilization interferes with the efficiency of fertilizers and the adoption of different methods of application must include the operational aspect, agronomical and economical. The study aims to evaluate the sources of efficiency of fertilizers and application methods in soybean. The study was conducted in 2012/2013 and 2013/2014 agricultural years a Oxisol, in Cruz Alta, RS, Brazil. The treatments consisted of four sources of fertilizer and two application methods in the experimental design of randomized blocks with four repetitions. The fertilizer sources are: MicroEssentials ® S9 pure (09.46.00); MicroEssentials ® S9 mixed with other raw materials (07.34.12); Monoammonium Phosphate (MAP); Formula 00.20.20, and the doses adjusted so as to be kept the same nutritional ratio at 92 kg ha -1 for P 2 O 5 and K 2 O, with the use of KCl (00.00.60) casting on the surface. Different sources were applied to broadcast at the soil surface and in the row. The highest soybean yield is associated with both the use of MicroEssentials ® S9 07.34.12 in the row or throw on the surface. The lower productivity of soybean is associated with the use of Formula 00.20.20, particularly when applied to the row sowing. The residual effect of the fertilizers sources applied only to the sulfur content (S) in the soil.
