et al. 2020

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.

“…The climate of the region is As', tropical hot and wet, according to the Köppen-Geiger classification (Silva et al 2019), with a rainy season in the autumnwinter, from March to August, mean annual rainfall depth of 995 mm, temperatures ranging from 22 to 26 ºC, and mean relative air humidity of 65 %. The soil of the experimental area was classified as a Planossolo Háplico Eutrófico mésico solódico (Alfisol; USA 2014), with moderate A horizon and sandy-loam texture (Santos et al 2018).…”

“…Sustainable alternatives to revert this process, such as the use of the crop-livestock-forest integration system, have been studied for this region, to assess the potential of these production systems for the recovering of degraded pastures (Rangeli et al 2016). Preliminary data have shown promising results (Silva et al 2019). However, the effects of integrated farming systems on the soil quality under the edaphoclimatic conditions of the semiarid region and the integration system strategies adopted (crop-livestock, crop-livestock-forest, crop-forest or livestock-forest, which show more satisfactory results) are little known.…”

Integrated farming systems are promising strategies for the recovery of pastures and degraded soils. This study aimed to evaluate the effect of integrated farming systems arrangements, after four years of implementation, on the fertility, carbon stock and aggregate stability of an Alfisol, in the semiarid region of the Paraíba state, Brazil. A randomized block experimental design was used, with 5 treatments and 4 replications: Brachiaria decumbens; B. decumbens + Tabebuia impetiginous; B. decumbens + Gliricidia sepium; B. decumbens + Mimosa caesalpiniifolia; and B. decumbens + maize. The soil chemical attributes, fertility, carbon stock and structural and aggregate stability were evaluated in the 0.00-0.10, 0.10-0.20 and 0.20-0.30 m layers. The B. decumbens + maize system presented an organic matter content 11.93 % higher than B. decumbens, and was higher than the other systems evaluated. Concerning the carbon stock in the 0.00-0.10 m layer, in B. decumbens the uptake was 2.66 Mg ha-1 higher than that of the B. decumbens + maize system and, on average, 4.69 Mg ha-1 higher than for the systems with the arboreal component. In the medium-term, B. decumbens is more efficient in adding carbon to the soil. The soil structural stability, aggregate stability index and fertility were not affected by the different arrangements after four years of implementation.

“…No nordeste do Brasil, a adoção dos sistemas integrados de produção agropecuária é recente e tem demonstrado bons resultados (Silva et al, 2019). Contudo, pouco se conhece sobre o impacto dos sistemas de integração na qualidade do solo sob clima semiárido no médio e longo prazo, e esse fato pode ser avaliado através de técnicas estatísticas que levam em consideração a avaliação integrada de um conjunto variáveis sensíveis as mudanças de uso do solo.…”

O objetivo deste trabalho foi avaliar a saúde de um solo sob sistema de integração Lavoura-Pecuária-Floresta através da análise multivariada dos atributos físicos, químicos e físico-hídricos do solo. O experimento foi implantado em um Planossolo Háplico de textura franco-arenosa no município de Alagoinha/PB, sob os seguintes consórcios em delineamento experimental de blocos casualizados: i) Br. decumbens + Gliricidia sepium (BG); ii) Br. decumbens + Mimosa caesalpiniifolia (BS); iii) Br. decumbens + Tabebuia alba (BI); iv) Br. decumbens + Zea mays (LA); v) Brachiaria decumbens (BD). Amostras (indeformadas e deformadas) de solo foram coletadas para avaliar propriedades físicas, físico-hídricas e químicas do solo nas camadas de 0,0-0,1; 0,1-0,2 e 0,2-0,3 m. As médias foram analisadas através da análise de componentes principais e correlação de Pearson (p<0,05). Os resultados indicaram que o Lavoura anual conseguiu agrupar o maior número de propriedades relacionadas à qualidade estrutural do solo. A densidade do solo apresentou correlações positivas e negativas com a maioria das propriedades físicas analisadas. Em relação as propriedades químicas, detectou-se maior agrupamento nos sistemas LA e BG na camada de 0-0,1 cm. Conclui-se que a análise multivariada é uma opção viável para avaliação da saúde do solo, por agrupar o maior número de propriedades possíveis dentro do sistema de manejo mais predominante.
