“…The efficiency of the S sources cited above has been investigated in areas under NT in Brazil. Thus, Fiorini et al (2016) found no differences in crop yield after application of elemental S and ammonium sulfate. In contrast, Broch et al (2011) found that various S sources, including single superphosphate, gypsum, and granulated gypsum, increased soybean yield, but elemental S did not.…”

“…The effect of S sources should be further investigated in order to clarify some contrasting results (Broch et al, 2011;Fano, 2015;Fiorini et al, 2016). In addition, the potential of S fertilization for improving quality in grain crops such as wheat should be better explored, as well as the effect of splitting S applications to ensure better adjustment of soil SO 4 2--S availability to plant requirements and reduce S losses by leaching (Ercoli et al, 2011;Fano, 2015).…”

“…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. Therefore, further consideration of these key drivers (viz., climate, soil chemical properties, crop type, and grain yield potential) for crop yield is imperative if management of S fertilization in Brazil is to be more sustainable.…”

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.

“…The need of sulfur in mineral nutrition of plants is already known for much time, mainly due to its participation in enzymes and protein formation. In general, soils cultivated for many years with continuous usage of concentrated fertilizers, hence with low levels of sulfur, end up generating deficiency of this element on the agricultural crops, mainly in the Cerrados region of Brazil [2].…”

A soja é uma cultura de destaque mundial, cujos grãos têm inúmeros usos na alimentação humana e animal. Dentre os nutrientes essenciais o enxofre é um macronutriente constituinte de proteínas e aminoácidos sendo requerido em quantidade considerável pelas leguminosas. O objetivo do trabalho foi determinar o efeito da utilização de enxofre, via aplicação foliar em diferentes estádios de desenvolvimento da soja, sobre características de desenvolvimento vegetativo e componentes de produtividade. O experimento foi conduzido a campo sob delineamento experimental em blocos casualizados com quatro repetições, em esquema fatorial 3x5 (3 épocas de aplicação via foliar e 5 doses de enxofre). A cultivar de soja TMG 132RR foi utilizada nessa investigação com as doses de 0, 250, 500, 750 ou 1000 mL ha-1 de enxofre aplicadas nos estádios V2, V2+10 ou V2+20 dias. A época de aplicação de enxofre foliar influenciou a produção de matéria seca da parte aérea e a altura de plantas, sendo o estádio V2+20 dias a época mais recomendada. A resposta às diferentes doses de enxofre variou com base nos resultados do teor de clorofila foliar e a altura de plantas. Para a produtividade de grãos houve interação entre época de aplicação de enxofre e dose, sendo a dose de 731 mL ha-1 aplicada em V2 a de máxima produtividade de3690 Kg ha-1. Os componentes de rendimento número de vagens por planta e número de grãos por vagem não foram afetados pelas épocas ou doses de aplicação de enxofre. Para peso de mil grãos as respostas às diferentes doses variaram conforme a época de aplicação.

“…Para a obtenção de boa safra, é imprescindível a adoção de práticas agronômicas adequadas, onde o manejo nutricional é um dos fatores mais importantes que afetam a tonelagem da cana-de-açúcar e manutenção das socas (Sing et al, 2015;Ismail et al, 2016). Um fator que tem influenciado o aumento na produtividade é o uso de fertilizantes minerais, entretanto, o elevado custo de processamento, produção e importação de fertilizantes torna a competitividade das comodities agrícolas brasileiras no mercado internacional um grande desafio (Fiorini et al, 2016). Com isso, o manejo da adubação é de grande importância para cultura tendo em vista sua relevância ao cenário econômico nacional (Nicchio et al, 2019).…”

Os macro e micronutrientes desempenham função importante no desenvolvimento e produtividade da cana-de-açúcar e aplicação foliar pode ser considerada uma ótima alternativa como adubação suplementar. Objetivou-se com este trabalho avaliar a produção, qualidade tecnológica e teores de nutrientes em soqueira de cana-de-açúcar submetida à aplicação de diferentes fertilizantes via foliar. Foram conduzidos três experimentos em áreas distintas, localizadas em áreas de unidades produtoras de cana-de-açúcar. Os experimentos foram instalados apresentando delineamento experimental de blocos casualizados, sendo cinco tratamentos (testemunha com água, controle visando fornecimento de N, B, Zn e Mn, Micro Foliar + N-Foliar nas doses de 1,0 kg ha-1 + 3,0 L ha-1, 2,0 kg ha-1 + 6,0 L ha-1 e 3,0 kg ha-1 + 10,0 L ha-1, respectivamente) com quatro repetições. As variáveis analisadas foram: altura de plantas, diâmetro de colmos, tonelada de colmos (TCH) e açúcar (TAH) por hectare, açúcar teórico recuperado (ATR), brix, pol da cana e teor foliar de N, B, Mn, Zn e Cu. A adubação foliar na dose de 1,56 kg ha-1 de Micro + 5,18 L ha-1 de N foi mais eficiente em aumentar a produção de açúcar para variedade RB 85-5536. O aumento de doses de Micro Foliar + N-Foliar (1, 2 e 3 kg ha-1 e 3, 6 e 10,0 L ha-1) foram mais eficientes em aumentar os teores foliares de nitrogênio, zinco e boro para variedade RB 86-7515.
