“…Accordingly, SOM content is an important factor associated with lime reactivity in subsurface soil. Combining ammonium-based fertilizer with liming provides favorable conditions for N nitrification [52]. Anionic nitrate (NO 3 − ) can be leached under the high density of soil negative charges caused by liming and carry basic cations via ionic pairs, which explains the higher concentrations of Ca 2+ and Mg 2+ in deeper layers, even though lime was applied solely on the soil surface.…”

Liming and N fertilization are common practices for optimizing crop yields in tropical agriculture, but the adequate N rate to ensure crop development, enhance yields and N use efficiency, and improve soil chemical properties has not been established for grass rotation. We assessed the optimal N fertilizer rate for combination with liming in an agricultural system composed of two grasses (maize and rice) in rotation under no-till (NT) conditions. Four N rates (0, 50, 100, and 150 kg N·ha−1) were tested under two liming conditions. Maize (11 Mg·ha−1) and rice (5 Mg·ha−1) yields were highest with lime and 150 kg N·ha−1 applications. At 18 months after liming, lime application increased soil pH. In addition, combining liming with N fertilization further increased SOM content at all N rates. Lime increased available P, exchangeable Ca2+ and Mg2+, and BS at N rates of 0, 50, and 100 kg N·ha−1. Overall, combining liming and N fertilization is beneficial for grass crops under NT conditions, as evidenced by enhanced maize and rice N use efficiency and yields. N fertilization rates of 100 and 150 kg N·ha−1 under lime amendment provided the best improvements in crop yields in this cropping system.

“…The relative abundance of Gemmatimonadota in PM and OF tests were significantly higher than that in CK tests by 29.87% and 27.70%, respectively (Figure 4a). It was shown that the soil amendments increased C concentrations (labile and stable fractions), improved soil physicochemical properties, and had positive associations with Gemmatimonadota bacterial groups [42]. Latescibacterota showed significant differences among different treatments, with the highest abundance during heading stage.…”

Agricultural fertilization significantly affects nutrients cycling in paddy soils. However, there are few systematic studies on the response of the application of livestock manure and corresponding organic fertilizer resulting in the microorganism and its nutrients entering farmland. Short-term application of pig manure and its corresponding organic fertilizer on the microorganisms of paddy fields were investigated. High-throughput sequencing technology was conducted to comprehensively study the microbial community composition and structure. Our results showed that organic fertilizer effectively enhanced nutrient substances such as nitrogen, phosphorus, and potassium at ripening stage and reduced the pH of soil, benefitting the soil fertility and the growth of rice. Though application of pig manure maintained higher microbial diversity, it increased the relative abundance of several pathogenic bacteria, which could threaten the soil health of the paddy fields. A large number of pathogenic bacteria can be reduced through composting pig manure to organic fertilizer. Nitrifying and denitrifying bacteria such as Anaerolineaceae, Pseudarthrobacter, Bacillus, and Nitrospira in the paddy soil were significantly promoted. The heavy metals such as Pb, Cr, and Cd, and nutrient substances such as phosphorus, as well as temperature, have important influences on the microbial compositions in ripening stage. The correlation analysis revealed more correlation efficiencies were observed with manure application, especially with the application of organic fertilizer. This study will provide a theoretical basis for improving land productivity and sustainable development in paddy fields.

“…The areas affected by open-pit mining are much larger than the quarry area ( Bekarevich et al 1969, Melnikov 1977, Monjezi et al 2008. Open-pit mining results in the formation of dumps which can serve as an example of a negative human impact on the ecosystem (Burlakovs et al 2017, Puell Ortiz 2017. This negative impact can be eliminated by implementation of mine reclamation techniques.…”

Activities connected to mineral mining disrupt the soil layer and bring up to surface parent rock material. As a result, they leave behind vast areas of disturbed lands, that are difficult to restore due to altered environmental conditions. Returning these lands to the natural ecosystems is an important contemporary challenge. Soil microbiome composition reflects changes happening to disturbed lands, its analysis helps to evaluate disturbance degree and estimate the effect of implementation of remediation techniques. Also, factors connected to the characteristics of a particular geographical region have a certain impact and should be taken into account. We focus on microbiomes of disturbed lands from two sandy-gravel mining complexes in mountainous areas with moderate continental climate (Central Caucasus, Russia). These quarries share the same parent rock material but differ in benchmark soil type and presence of remediation practices. Comparative analysis of microbiome composition based on sequencing of 16S rRNA gene libraries showed that region and disturbance are the key factors explaining microbiome variation, which surpass the influence of local vegetation factors. However, application of remediation techniques greatly reduces dissimilarity of soil microbiomes caused by disturbance. Linking of soil agrochemical parameters to microbiome composition showed that disturbance factor correlates with a lack of organic carbon. Other agrochemical parameters, like pH, ammonium, nitrates and total carbon explain variation of microbiomes on a smaller scale between sampling sites. Thus, while regional and disturbance factors reflected differentiation of soil microbiomes, soil agrochemical parameters explained local variation of certain groups of microorganisms.
