Carta De Susceptibilidade a Infiltração Da Água No Solo Na Sub-Bacia Do Rio Maracanã-Ma

Abstract: O estudo do comportamento da infiltração na sub-bacia do Rio Maracanã buscou o entendimento do comportamento da infiltração da água na sub-bacia do Rio Maracanã, onde foram realizados teste de infiltração in situ com infiltrômetro de duplo anel, associado aos conhecimentos geológicos-geotécnicos da área que subsidiou a elaboração da Carta de susceptibilidade a infiltração da água no solo da sub-bacia do Rio Maracanã utilizando o método de krigagem. As áreas de recarga estão severamente impactadascom baixa susc… Show more

“…According to Lanzanova et al (2007), the soil water infiltration was more sensitive to characterize the negative effect of cattle trampling on high grazing frequencies in CLI systems. This fact is due to attributes such as soil texture and structure, which are decisive in the movement of water in the soil profile, as they influence the quantity, size, and continuity of soil pores (Santos & Pereira, 2013). The BIR values reached 15.87,32.23,59.19,and 60.48 mm h −1 for grazing heights of 10, 20, 30, and 40 cm, respectively ( Figure 3).…”

“…These no-tillage areas are characterized by the non-return of the soil, or seja¸ by the permanence, for varying periods, of the residues of the previous crop and of the plant on the surface, which leads to an increase in the total porosity of the area, especially the macroporosity that exerts a great influence on the infiltration of water into the soil. It is noted that the effect of plant cover provides sufficient protection for the dissipation of the kinetic energy of raindrops, offering barriers to the sealing of the soil surface and consequently to the runoff of water, improving the soil water infiltration (Santos and Pereira 2013;Montenegro et al 2013;Nicholls and Altieri 2012;Nunes et al 2012). Almeida et al (2016) concluded that no-tillage is an efficient system for soil conservation or its recovery and in it, the organic matter assigned, improves the soil's physical conditions.…”

“…**(p < 0,01). vez que contribui com a retenção de água, e, associado a menor intensidade de revolvimento, melhoram a estruturação do solo e favorecem o desenvolvimento radicular (Araújo et al, 2004;Franchini et al, 2009;Santos & Pereira, 2013). Como o comportamento físico-hídrico do solo está condicionado a melhor distribuição no diâmetro dos poros (Carducci et al, 2013), sendo os poros maiores responsáveis pela maior infiltração e permeabilidade da água, trocas gasosas e crescimento das raízes (Dexter, 2004a, b, c), foi verificado que houve maior volume de poros da classe de diâmetro maior Nesse sentido, para o PMP, observou-se o comportamento: sistemas de manejos sob pastagens > Mata (Tabelas 3 e 4).…”
