“…Lower values cause a reduction in crop productivity. Reichert, Suzuki, and Reinert (2007) also state that the critical values of macroporosity for plant growth are established, being close to 10%. According to Gubiani (2012), however, these values are not yet fixed, as in soils managed under no-till systems and with excellent drainage, critical macroporosity values may be even lower.…”

“…This conclusion corroborates the results found by Andrade and Stone (2009), in which the authors report that a soil is required to have at least 50% total porosity to perform its functions in soil physics. According to Secco (2005), total porosity presents an inverse relationship with compaction and a direct relationship with penetration resistance.…”

“…In addition, spectroscopy in the visible (Vis: 400-700 nm), near infrared (NIR: 701-1100 nm), and short-wave infrared (SWIR: 1101-2500 nm) regions of the electromagnetic spectrum associated with chemometric methods has allowed the quantification of physical, chemical, and mineralogical soil properties (Viscarra Rossel and Behrens, 2010). This technique has become a well-established method to assess soil properties rapidly and accurately in the laboratory (Ben Dor et al, 2015), with the possibility of predicting several properties in just one spectral reading, facilitating data acquisition from large amounts of samples, and without the use of environmentally hazardous chemicals (Dotto et al, 2016(Dotto et al, , 2018Demattê et al, 2019).…”

“…A matéria orgânica do solo desempenha um papel de grande importância nos solos tropicais e subtropicais, pois influencia nas propriedades físicas, químicas, biológicas e mineralógicas, sendo essencial à capacidade produtiva dos solos. Concomitantemente, a presença de matéria orgânica apresenta forte relação com a resposta espectral do solo (DALMOLIN, 2002;BEN-DOR et al, 2002;DOTTO et al, 2016;MOHAMED et al, 2018).…”

“…Técnicas de sensoriamento remoto, como a espectrorradiometria, vêm ganhando espaço no estudo de solos. Diversos estudos desenvolvidos em diferentes classes de solos (DALMOLIN, et al, 2005;ARAÚJO et al, 2013;DEMATTÊ et al, 2014;DOTTO et al, 2016;SANTOS et al, 2018) demonstram a capacidade de predizer características físicas, químicas e mineralógicas do solo por meio da sua resposta espectral, de maneira rápida e não destrutiva desse corpo natural que é responsável pela segurança alimentar e ambiental.…”
