“…BD is considered a measure of soil quality due to its relationships with other properties (e.g., porosity, soil moisture, and hydraulic conductivity; Dam et al, ). In northern China, high soil BD might negatively affect the transport of water and solutes and root growth, thereby reducing crop growth and grain yield (Jin, White, Whalley, Shen, & Shi, ; Singh, Choudhary, Singh, Singh, & Mishra, ; Wang et al, ). BD was highly negatively correlated with grain yield, but recycling treatments substantially decreased it (Table ).…”

“…However, the depth of deep tillage and subsoiling generally ranges from 25 cm to 35 cm (Jin et al 2007;Motavalli et al 2003). Singh et al (2019aSingh et al ( , 2019b reported that subsoiling exerted a beneficial effect on soil physical properties by reducing the bulk density and improving the infiltration rate, and any subsoiling at 1.0 or 1.5 m once in 3 years has the potential to improve the productivity of cotton-wheat cropping systems.…”

“…Reeves and Mullins (1995) reported that subsoiling was necessary for maximum cotton yields on coastal plain soils with root-restricting hardpans. Borghei et al (2008) and Singh et al (2019aSingh et al ( , 2019b also reported that subsoiling improved soil productivity and cotton yield. However, Khalilian Akinci et al (2004) documented that the subsoiling treatments created statistically significant effects on the soil texture but did not affect cotton yield.…”

Background: Long-term rotary tillage has led to the deterioration of cotton production in northern China. This deterioration is due to the disturbance of topsoil, a dense plough pan at the 20-50 cm depth, and the decreased water storage capacity. A 2-yr field experiment was performed from 2014 to 2015 to explore a feasible soil tillage approach to halting the deterioration. The experiment consisted of four treatments: replacing the topsoil from the 0-15 cm layer with the subsoil from the 15-30 cm layer (T1); replacing the topsoil from the 0-20 cm layer with the subsoil from the 20-40 cm layer and subsoiling at the 40-55 cm layer (T2); replacing the topsoil from the 0-20 cm layer with the subsoil from the 20-40 cm layer and subsoiling at the 40-70 cm layer (T3); and conventional surface rotary tillage within 15 cm as the control (CK). Results: The results indicated that the soil bulk densities at the 20-40 cm layer in T2 were 0.13 g•cm − 3 and 0.15 g•cm − 3 lower than those obtained from CK in 2014 and 2015, respectively. The total nitrogen (N) and the available phosphorus (P) and potassium (K) contents from the 20-40 cm layer in T2 and T3 were significantly higher than those in CK and T1. The amount of soil water stored in the 0-40 cm layer of T2 at the squaring stage of cotton was 15.3 mm and 13.4 mm greater than that in CK in 2014 and 2015, respectively, when the weather was dry. Compared with CK, T2 increased cotton lint yield by 6.1 and 10.2 percentage points in 2014 and 2015, respectively, which was due to the improved roots within the 20-60 cm layer, the greater number of bolls per plant and the higher boll weight in the T2 treatment. Conclusions: The results suggested that soil replacement plus subsoiling would be a good alternative to current practices in order to break through the bottleneck constraining cotton production in northern China. Replacing the topsoil in the 0-20 cm layer with the soil from the 20-40 cm layer plus subsoiling at the 40-55 cm layer would be the most effective method.

“…Já que o carbono orgânico do solo, proveniente da MOS atua fortemente na porosidade e estrutura dos poros, elevando a capacidade de armazenamento e a dinâmica de gases (Song et al, 2019). Singh et al (2019) avaliando o crescimento e produtividade de algodoeiro em um solo de textura argilo-arenosa na Índia, observaram que a redução de densidade do solo elevou a produtividade do algodão por três safras consecutivas.…”

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.
