“…At the moment of evaluation, the soil gravimetric moisture values were 20% and 22% until 40 cm deep for 2018 and 2019, and Rp values ranged from 0.23 MPa to 2.01 MPa in the first year and from 0.21 MPa to 2.57 MPa in the second. According to Petean et al (2010) and Andreolla et al (2015b), values above 2.5 MPa limit the soil resistance to penetration. On the other hand, Moraes et al ( 2014b) report that values above 3.5 MPa are a limitation for clayish soils with no-till farming in the state of Paraná.…”

Os sistemas integrados de produção lavoura-pecuária (SIPAs) em associação ao sistema de semeadura direta, sofrem ação do pisoteio animal ou do tráfego intenso de máquinas agrícolas, podendo resultar em alterações nas propriedades físicas do solo. O objetivo deste trabalho foi avaliar o efeito da adubação nitrogenada e manejos das forrageiras tropicais nas propriedades físicas do solo. O experimento foi realizado entre outubro de 2017 e janeiro de 2020, em Marechal Cândido Rondon – PR, em blocos ao acaso, com parcelas sub-subdivididas com uma testemunha adicional e quatro repetições. As parcelas foram constituídas por duas espécies forrageiras consorciadas com o milho: Urochloa brizantha e Magathyrsus maximum, mais a testemunha adicional (milho solteiro). As subparcelas consistiram nos manejos das forrageiras: fenação e pastejo; e nas sub-subparcelas, a presença ou ausência de adubação nitrogenada. Foram determinadas: densidade do solo (Ds), porosidade total (Pt), macro (Ma) e microporosidade (Mi), além da resistência do solo à penetração (Rp). A utilização de nitrogênio (N) em cobertura nas forrageiras após os manejos, aumentou a quantidade de Ma na camada de 0-0,05 m para o primeiro ano. Os valores de Ds estão acima do limite considerado crítico para o desenvolvimento das plantas, porém, com tendência à redução. A adoção do SIPA, independente da espécie forrageira utilizada e manejo adotado, seja fenação ou pastejo, não comprometeu a qualidade física do solo, sendo assim, uma ótima alternativa para a diversificação da produção na propriedade.

“…Several studies have evaluated how livestock grazing changes agroecosystem properties under conservation soil management with moderate grazing intensity and adequate soil fertility. Livestock impacts on soils have mostly been nil or positive regarding chemical (e.g., Carvalho et al, 2010; Deiss et al, 2016; Martins et al, 2014, 2016), physical (e.g., Andreolla et al, 2015; Andreolla, Bonini, Deiss, Sandini, 2014) and biological attributes (e.g., Acosta‐Martínez, Bell, Morris, Zak, et al, 2010; Acosta‐Martínez, Dowd, Sun, Wester, et al, 2010; Chávez et al, 2011; Davinic et al, 2013). Fewer studies, however, have addressed the trade‐offs these positive changes in soil properties might have for soil exchangeable complex composition (i.e., base saturation) and essential micronutrient availability.…”

Soil fertility under no-tillage farming may be affected by agricultural complexity. By transforming most of the ingested pasture into urine and faeces, ruminants catalyse nutrient cycling by breaking down complex plant molecules, which can help to maintain or even improve soil fertility. We evaluated how integrating annual crops and the ruminant grazing of cover crops in the same land area and at overlapping times affect soil fertility in no-tillage systems. Soil chemical properties were evaluated at 0-5-cm and 5-25-cm depths, in three long-term cropping experiments (7, 10 and 12 years) with and without ruminant grazing of cover crops. The three sites had contrasting soil and climatic char acteristics, but all sites were managed under no-tillage, and treatments with livestock were managed with moderate grazing intensity. Ruminant grazing increased soil Na and P concentrations at 0-5-cm depth, and increased Ca and Mg availability, base saturation and pH in deeper layers (5-25-cm depth) or across the soil profile (0-25 cm). Land-use complexity changed the soil exchangeable complex, resulting in soil acidity amelioration and consequently reduced Al toxicity, but it also had a negative impact on K saturation and cationic micronutrient availability (Zn, Mn, Cu and Fe). In general, grazing improved or did not change most soil chemical properties, and any negative effects of animal presence did not limit agroecosystem productivity. Therefore, under appropriate nutrient and grazing management, no-tillage farming with integrated crop-livestock systems can uphold soil chemical conditions to sustain primary and secondary productivities in agroecosystems.

Integrated crop–livestock–forest is a promising strategy to improve soil quality. It comprises four different integrated farming systems: crop–livestock, crop–forest, forest–livestock and crop–livestock–forest. This work systematically reviewed studies about integrated crop–livestock–forest systems and soil quality. A total of 92 papers were retrieved from the Web of Science—Clarivate Analytics platform, and the following information was analysed: publication year, institution, region of the studied site, type of integrated system, soil type, tillage system, maximum soil depth and the soil quality indicators assessed. Most studies were published in the second half of the 2010s. Brazil is a prominent focus of research about soil quality and integrated crop–livestock–forest systems, with significant contribution from its central and southern regions. The Embrapa was the main publishing institution, present in over one‐third of the studies. Crop–livestock was the most common integrated system, Ferralsols was the most common soil group, and most of the studied soils were clayey. No tillage was the main tillage system. Most studies focused on the topsoil, assessing physical and/or chemical soil quality indicators. More emphasis on biological indicators of soil quality is required, as well as assessments integrating biological, physical and chemical indicators of soil quality. Future works should compare different integrated systems, including assessments deeper in the soil profile, especially in systems with the forest component, and also in sandy and silty soils. Soil quality indicators that have been rarely used should be further tested. Novel indicators should be added to better understand the promotion of soil quality by integrated crop–livestock–forest systems.
