Resistência mecânica do solo à penetração em sistema silvipastoril após onze anos de implantação

Abstract: Com a crescente demanda por alimentos, surge a necessidade de intensificação no uso do solo, convergindo para sistemas de produção com características de sustentabilidade. Uma alternativa, aplicada à agricultura, é a adoção de sistemas integrados de produção agropecuária, como exemplo está o sistema silvipastoril. A integração entre sistemas de produções visa maximizar o uso dos recursos naturais e dos insumos, com menos impacto sobre o ambiente e maior ganho em produtividade da área. Nesse sentido, os efeitos… Show more

“…The 0.00-0.15 m layer exhibited lower values and despite animal trampling, it is assumed that the roots helped maintain the lower compaction (Costa et al, 2015). Sartor et al (2020) observed that one of the main forms of compaction, in addition to the use of machinery and the constant grazing of animals on agricultural properties, is the deposition of particles in the soil profile that are displaced by rainfall, increasing PR at different depths. Cortez et al (2019) studied the spatial variability of soil penetration resistance in a no-tillage system in the municipality of Dourados, Mato Grosso do Sul state, Brazil, in a dystrophic red latosol, and their maps showed that higher PR was also found in more superficial layers, at a depth of 0.00-0.25 m.…”

“…Farmers face problems such as soil penetration resistance (PR), making them more dependent on soil tillage implements (Aydin et al, 2020;Silva et al, 2020). However, these practices incur high operating costs and their effects on the soil may be short-lived (Nunes et al, 2019).…”

“…The traffic of machines and implements in the last decades has resulted in the modification of the physical attributes of the soil, such as a reduction in the availability of water and air and an increment in soil resistance, impairing the exploration by the roots of plants in depth (Silva et al, 2017). In addition, rainwater infiltration is reduced, increasing surface runoff and limiting the development of the root system of the plant, causing a reduction in growth and productivity (Sartor et al, 2020).…”

“…Conforme destacado por Shi et al (2012), a compactação pode aumentar a densidade e reduzir o volume de poros no solo, o que resultaria em perda na condutividade hidráulica e redução do alongamento radicular das plantas. Ressalta-se em locais nos quais os solos são manejados inadequadamente, como as áreas pastagens, o pisoteio animal pode elevar a compactação do solo em superfície ocasionando degradação (Benevenute et al, 2020), além de tender o aumento em profundidade do solo, que modificam a conformação dos agregados, como observado por Sartor et al (2020).…”
