“…It is conjectured that this increase in production is a consequence of a set of changes caused by water magnetization, such as variations in the absorption value, pH, conductivity, and soil hardness (Ozeki, Miyamoto, Ono, Wakai, & Watanabe, 1996;Nasher, 2008;Khoshravesh, Mostafazadeh-Fard, Mousavi, & Kiani, 2011;Lyn & Yotavat, 1990). From the perspective of providing a detailed analysis of the effects of different technologies applied in agriculture, fuzzy mathematical models are being proposed as efficient and alternative methodologies for decision making, as illustrated by Gabriel Filho, Pigatto, and Lourenzani (2015), Pereira, Bighi, Gabriel Filho, and Cremasco (2008), Putti, Gabriel Filho, Silva, Ludwig, and Cremasco (2014), and Putti et al (2017a).…”
