A Comparison of indexes to estimate corn S uptake and S mineralization in the field
(2018-04)The development of simple predictors of sulfur (S) mineralization and its correlation with field-derived data may help improving corn S availability diagnosis. The objectives of this study were (1) to compare methods to ... -
Diagnosis of sulfur availability for corn based on soil analysis
(Springer Berlin Heidelberg, 2016-10)Different edaphic properties were evaluated to diagnose soil sulfur (S) availability for corn in 15 field experiments as follows: (a) soil sulfate (SO4 −2-S) content at sowing at 0–20 cm and 0–60 cm depths [Sini(0–20) and ... -
Improving soil organic nitrogen and sulfur pools by cover cropping and crop fertilization in soybean-based cropping systems
(Elsevier, 2021-07-10)Nitrogen (N) and sulfur (S) define crops productivity, and are currently deficient in most agricultural soils. In agricultural systems, management practices can affect N and S organic pools (Norg and Sorg, respectively). ... -
N and S concentration and stoichiometry in soybean during vegetative growth: Dynamics of indices for diagnosing the S status
(Elsevier, 2016-11)Information regarding the pattern of sulphur (S) accumulation in shoots is scarce for field crops and few comprehensive analysis were performed on N:S stoichiometry. Particularly, the need to study the patterns of uptake, ... -
Prognosis and diagnosis of sulfur status in maize by plant analysis
(Elsevier, 2019-05)The analysis of sulfur concentration (SC) and nitrogen to S ratio (N/S) in plant tissue are some of the suggested tools to evaluate S deficiency in maize (Zea mays L.). However, the convenience of one over the other and ... -
Sulfur affects root growth and improves nitrogen recovery and internal efficiency in wheat
(2017)Wheat plants were cultivated in pots with the objective of evaluate the effect of two sulfurrates (+S and -S) on i) shoot growth, S and nitrogen uptake and nitrogen use efficiency(NUE) and ii) root growth and architecture ... -
Sulfur Mineralization: A Key Process for Diagnosing Its Deficiency in Wheat
(Soil Science Society of America, 2019-09)Core Ideas: A simplified balance was used to calculate apparent S mineralization in wheat. Apparent S mineralization predicted relative wheat grain yield. Sulfate‐S before sowing combined with particulate organic C diagnosed ...
