Carbon stock and humification index of organic matter affected by sugarcane straw and soil management
A. Segnini,João Luís Nunes Carvalho,Denizart Bolonhezi,Débora Marcondes Bastos Pereira Milori,Wilson Tadeu Lopes da Silva,Marcelo Luiz Simões,Heitor Cantarella,Isabella Clerici De Maria,Ladislau Martin-Neto +8 more
TL;DR: In this paper, the impact on soil carbon stocks and the humification index of soil organic matter (SOM) of adopting no-tillage (NT) and conventional tillage (CT) for sugarcane replanting was assessed.
Quantification of total carbon in soil using laser-induced breakdown spectroscopy: a method to correct interference lines
Gustavo Nicolodelli,Bruno S. Marangoni,Jader Cabral,Paulino Ribeiro Villas-Boas,Giorgio S. Senesi,Cleber Hilario dos Santos,Renan Arnon Romano,A. Segnini,Yves Lucas,Célia Regina Montes,Débora Marcondes Bastos Pereira Milori +10 more
TL;DR: A method was developed capable of separating the Al interference from the C emission line in LIBS measurements, and the strong correlation found between the LIBS values and those obtained by a reference technique (dry combustion by an elemental analyzer) supported the validity of the proposed method.
Physical and Chemical Matrix Effects in Soil Carbon Quantification Using Laser-Induced Breakdown Spectroscopy
A. Segnini,Alfredo Augusto Pereira Xavier,Pedro Luis Otaviani-Junior,Edilene Cristina Ferreira,Alex Watanabe,Marco Aurélio Sperança,Gustavo Nicolodelli,Paulino Ribeiro Villas-Boas,Patrícia Perondi Anchão Oliveira,Débora Marcondes Bastos Pereira Milori +9 more
TL;DR: In this paper, the authors quantify the carbon content of soils with differ-ent textures and with high iron and aluminum concentrations using LIBS, and the results indicated that LIBS quantification can be affected by the texture and chemical composition of soil.
Soil carbon stock and humification in pastures under different levels of intensification in Brazil
A. Segnini,Alfredo Augusto Pereira Xavier,Pedro Luis Otaviani-Junior,Patrícia Perondi Anchão Oliveira,André de Faria Pedroso,M. F. F. M. Praes,Paulo Henrique Mazza Rodrigues,Débora Marcondes Bastos Pereira Milori +7 more
TL;DR: In this article, the authors evaluated different pasture management options in relation to their effect on soil C stocks and soil organic matter (SOM) humification, and indicated the capacity of adequately managed tropical pastures to mitigate GHG emissions from livestock production.
Spectroscopic Assessment of Soil Organic Matter in Wetlands from the High Andes
A. Segnini,Adolfo Posadas,Roberto Quiroz,Débora Marcondes Bastos Pereira Milori,Sérgio da Costa Saab,Ladislau Martin Neto,Carlos Manoel Pedro Vaz +6 more
TL;DR: In this paper, the results obtained by both techniques were comparable (R 2 = 0.88) and proven to be reliable indicators of increased or reduced SOM stability and thus suitable methods for assessing its humification index.
