“…Clayey soils with oxidic mineralogy adsorb sulfate more readily, thereby reducing leaching of the anion to subsurface layers (Alvarez V et al, 2007;Ercoli et al, 2011). However, these soil conditions may also result in high stabilization of OM through organomineral interactions and thus detract from microbial decomposition and S mineralization of OM (Cotrufo et al, 2013), which is the main source of available SO 4 2--S for plants (Alvarez V et al, 2007;Tiecher et al, 2013). In contrast, most low OM soils have lower physical, chemical, and microbiological quality (Mendes et al, 2018), which may lead to decreased crop grain yields and, consequently, decreased S requirements (Alvarez V et al, 2007).…”

“…In contrast, most low OM soils have lower physical, chemical, and microbiological quality (Mendes et al, 2018), which may lead to decreased crop grain yields and, consequently, decreased S requirements (Alvarez V et al, 2007). Another factor to be considered is atmospheric deposition of S, which increases with nearness to the sea or an industrialized city (Tiecher et al, 2013;Vieira-Filho et al, 2015). This deposition can thus have a confounding effect of texture and soil OM content on crop response to S fertilization.…”

“…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).…”

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.

“…In addition, the ability of the soil to supply the nutrient demand of the plant is closely related to the organic matter content of the soil and the mineralization of organic S to inorganic forms (Tiecher et al, 2013). However, in the soil solution, sulfate is easily leached, and retained by the mechanisms of adsorption by coordination (Ishiguro & Makino, 2011).…”

A viable alternative to increase productivity in rice cultivation areas has been the investment in macronutrient fertilization. Sulfur (S) is an essential nutrient for plants, as it participates in the formation of several organic molecules, being essential to ensure high yields of rice. The aim of this paper is to analyze the rice crop performance in two types of irrigated floodplain soils under different doses of sulfur fertilization. The experiment was carried out on two lowland soils in Formoso do Araguaia-Tocantins, Brazil, under a randomized block design, in a 2 × 8 factorial arrangement, two soil types and eight sulfur doses, using ammonium sulfate as the source of S (0, 10, 20, 30, 40, 50, 60 and 70 kg ha -1 of S). The doses were applied when the plants were in the V3-V4 development stage in both soils. S provided plant a growth up to 40 kg ha -1 , which is the economical feasible dose for plant height in soil 1. With the increase of the dose of S over 60 kg ha -1 in soil 2, there was a decrease in the number of panicles per m 2 . There was an increase in productivity in soil 2 and reduction in soil 1. The highest grain yield was obtained in soil with higher clay content. The dynamics of sulfur fertilization in floodplain soils requires further studies for a better understanding.

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.
