“…In this study, intercropping treatment significantly increased the contents of SOM compared with maize monoculture. This is consistent with previous studies that demonstrated that soil organic carbon fraction, carbon pool management index and soil carbon sequestration were improved under intercropping [4,37,38].…”

Conservative agricultural practices have been adopted to improve soil quality and maintain crop productivity. An efficient intercropping of maize with mushroom has been developed in Northeast China. The objective of this study was to evaluate and compare the effects of planting patterns on the diversity and structure of the soil bacterial communities at a 0–20 cm depth in the black soil zone of Northeast China. The experiment consisted of monoculture of maize and mushroom, and intercropping in a split-plot arrangement. The characteristics of soil microbial communities were performed by 16S rRNA gene amplicom sequencing. The results showed that intercropping increased soil bacterial richness and diversity compared with maize monoculture. The relative abundances of Acidobacteria, Chloroflexi, Saccharibacteria and Planctomycetes were significantly higher, whereas Proteobacteria and Firmicutes were lower in intercropping than maize monoculture. Redundancy analysis suggested that pH, NO3−-N and NH4+-N contents had a notable effect on the structure of the bacterial communities. Moreover, intercropping significantly increased the relative abundance of carbohydrate metabolism pathway functional groups. Overall, these findings demonstrated that intercropping of maize with mushroom strongly impacts the physical and chemical properties of soil as well as the diversity and structure of the soil bacterial communities, suggesting this is a sustainable agricultural management practice in Northeast China.

“…Essas diferenças possivelmente decorrem de um maior teor matéria orgânica na subárea 1, cujo valor é 40% maior que na subárea 2. A respeito da importância da matéria orgânica do solo, ela exerce melhorias dos atributos químicos com o aumento da capacidade de troca catiônica (CTC), melhorias nos atributos biológicos e, também, nos atributos físicos, como por exemplo aumento da retenção hídrica do solo (Soares et al, 2019;Salomão et al, 2020;Oliveira et al, 2021). Médias seguidas de mesma letraminúscula nas colunas e médias seguidas de mesma letra maiúscula nas linhas não diferem entre si pelo teste de Tukey ao nível de 5% de significância.…”

Objetivou-se avaliar o índice de sobrevivência de espécies nativas do cerrado em função da calagem. O experimento foi realizado em uma microbacia do rio Pandeiros. A área experimental apresentava solo com baixo pH, baixa saturação por bases e fortes sinais de degradação antrópica. Na área de empréstimo à montante de terraços construídos com a finalidade de conter a erosão foi realizado o plantio de espécies florestais nativas pioneiras e não pioneiras, testando a ausência e a presença de calcário dolomítico nas covas de plantio. O plantio foi realizado em duas subáreas dentro da microbacia. Para a subárea 1, as espécies pioneiras testadas foram o Angico Vermelho (Anadenanthera macrocarpa), Aroeira (Lithraea molleoides) e Pau Ferro (Caesalpinia ferrea); já para a subárea 2 as espécies testadas foram: Gonçalo Alves (Astronium fraxinifolium), Carne de Vaca (Clethra scabra) e Farinha Seca (Albizia hasslerii). As espécies secundárias inicial e não-pioneira plantadas entre as espécies pioneiras foram respectivamente o Ipê Amarelo (Tabebuia ocharea) e o Jatobá (Hymenaea courbaril), sendo utilizadas essas espécies para as subáreas. Após 449 dias foi a avaliado o índice de sobrevivência das espécies pioneiras e não pioneiras para as subáreas 1 e 2. De maneira geral não se verificou efeito da calagem na sobrevivência de plantas. Para a subárea 1, a espécie com maior índice de sobrevivência foi o Pau Ferro. Para a subárea 2, a espécie com maior índice de sobrevivência foi o Gonçalo Alves. A subárea 1 apresentou maior índice de sobrevivência de espécies não pioneiras que a subárea 2.

“…The quantity of crop residue remaining on the soil surface under each tillage technology is crucial, as it affects the quality of tillage and sowing, soil characteristics, the state of weed and disease and, finally, the productivity and quality of crops [11,12]. For example, we found a strong correlation between soil stability in water (at the depths of 0-15 and 15-25 cm) and the content of precrop residues (r = 0.897 and 0.906 at P ≤ 0.05) [26].…”

“…First of all, conventional tillage with intensive incorporation of crops' residues rapidly increases the content of organic matter and changes the soil moisture content, temperature, aeration, and other soil physico-mechanical properties [4][5][6][7][8][9]. Later, aerobic conditions and additional organic matter stimulate microbial activity and activate respiration gases and CO 2 losses from the soil [10][11][12].…”

Soil tillage intensity influences the chemical composition of soil, the distribution of nutrients, and soil physical and mechanical properties, as well as gas flows. The impact of reduced tillage on these indices in faba bean cultivation is still insufficient and requires more analysis on a global scale. This study was carried out at Vytautas Magnus University, Agriculture Academy (Lithuania) in 2016–2018. The aim of the investigation was to establish the influence of the tillage systems on the soil chemical composition, temperature, moisture content, and CO2 respiration in faba bean cultivation limited by the semi-humid subarctic climate. On the basis of a long-term tillage experiment, five tillage systems were tested: deep and shallow moldboard plowing, deep cultivation-chiseling, shallow cultivation-disking, and no-tillage. Results showed that in conditions of plowless tillage systems, the content of precrops’ residues on the topsoil before the spring tillage was 5 to 15 times higher than in plowed plots. It undoubtedly was for the amount of available nutrients in the soil, soil temperature, and moisture content. Plowless and no-tillage systems could initiate an increase in the amount of available nutrients in soil. The highest concentration of chemical elements was found in no-tilled plots. So faba bean crops could largely increase the composition of potassium and total nitrogen and stabilized CO2 respiration from soil during one vegetative period.
