“…The layers at the depth of 5.0-10.0 cm are characterized by low permeability, generally presenting a hard structure, with limited porosity and little biological activity (Yagi et al 2014). In the present study, depths of 2.0-7.0 cm presented a consumption without variation among the treatments (Table 1).…”

To preserve a desirable level of soil quality, especially taking into consideration its health and sustainability, is not an easy task, due to the numerous factors that influence it. This study aimed to measure the feeding activity of soil fauna in production systems under cover crop straws sampled at the depth of 0-8.0 cm. A randomized blocks design, with four replicates and eight treatments, was used, corresponding to soybean cultivation under the following cover crop straws: maize monoculture; maize intercropped with Urochloa ruziziensis; U. ruziziensis monoculture; sorghum intercropped with U. ruziziensis; sorghum monoculture; sunflower intercropped with U. ruziziensis; mix (millet + Crotalaria spectabilis + U. ruziziensis); and a fallow treatment. At the depth of 1.0 cm, there was a variation of 63.59-37.06 % for consumption among the treatments, with the highest consumption for the mix, if compared to the fallow treatment. At the depth of 2.0-7.0 cm, the consumption did not vary among the treatments. For the depth of 8.0 cm, the fallow treatment presented the highest consumption (45.76 %; p < 0.05), when compared to sunflower intercropped with U. ruziziensis (20.51 %), sorghum (20.58 %) and sorghum intercropped with U. ruziziensis (18.96 %).

“…The increase in SOM content with depth in IL soil may be associated with the less favorable conditions of subsurface layers for microbial decomposition. This factor, associated with the incorporation of plant residues and high soil clay content, promotes chemical and physical protection of organomineral complexes through cation bond formation (Yagi et al, 2014).…”

“…Lime can be applied to the surface or incorporated into the soil by tillage. Many studies have verified that surface application does not involve any problems for the soil; therefore, it is the most suitable scheme for lime application under no-tillage management (Yagi et al, 2014). Liming material can reduce acidification by increasing soil pH and Ca 2+ concentration and by decreasing Al toxicity in the field (Shaaban et al, 2015).…”

Reducing greenhouse gas emissions and increasing agronomic productivity by sustaining soil organic matter and refining soil fertility have become the main concerns for agricultural scientists. There is a new approach to decrease greenhouse gas emissions, soil C sinks, and improve soil quality using biochar. Soil acidification is improved by applying lime or other acid-neutralizing materials. Additionally, Ca and Mg can increase by applying lime. The availability of Ca, Mg, and K in the soil is significantly affected by the application rate of biochar spread separately or combined with chemical fertilizers. Soil nutrients and maize (Zea mays L.) yield are highly influenced by the use of lime and biochar. Biochar can improve the ecosystem by reducing soil CO2 emissions from agricultural practices. The inconsistent results and clarifications from various studies highlight the importance of relating the impact of different biochar rates on CO2 emissions and maize yield. This review summarizes the properties of biochar, provides the scientific reference for its application to achieve high and good quality maize and reduce CO2 emissions.
