“…The decomposition of green manure will affect the soil nutrients, and the latter will affect the structural diversity and abundance of the soil microbial community [5,6,18]. Microorganisms are the main driving force of the soil nutrient material cycle, and the microbial communities in the soil are vulnerable to the influence of the external environment; thus, they react to the soil environment [37,38]. In this study, most of the top 20 bacterial groups significantly correlated with the characteristics of plant decomposition and soil nutrient content, including Proteobacteria, Actinobacteria, Armatimonadetes, Rokubacteria, and Planctomycetes that extremely significantly correlated with soil nutrients and plant properties before and after decomposition.…”

The rapidly emerging fertilizer rapeseed used as green manure has wide applications for use. However, there have been few studies on its decomposition and effects on soil nutrients and microorganisms after its decay. In this study, 12 rapeseed lines to be screened were decomposed through a randomized block field design with two green-manure-specific varieties as the controls. The contents of nitrogen, phosphorus, and potassium from the plants, soil nutrients, and microbial changes after degradation were measured. There were substantial differences in the rates of decomposition and cumulative release of nutrients among the different lines after 30 days of rolling. The contents of phosphorus and potassium in the soil were 1.23–2.03 and 3.93–6.32 times those before decomposition, respectively. In addition, there was a significant difference in the relative content of soil microorganisms at the phylum level after the decomposition of different species of rapeseeds. Most of the top 20 bacterial groups significantly correlated with the characteristics of plant decomposition and soil nutrient content, including Proteobacteria, Actinomycetes, Armatimonadetes, Rokubacteria, and Planctomycetes. A principal component analysis showed that the soil microorganisms and nutrients are the leading factors that enable the evaluation of the decomposing characteristics of green manure rapeseed. Numbers 5 (purple leaf mustard) and 8 (Xiafang self-seeding) were more effective than two controls, which can be used as excellent types of germplasm to promote the breeding of green manure rapeseed.

“…The relationship between SiAP and nitrogen in this study was positive, while Chirkes Johanna et al (2018) reported that the relationship between SiAP and total nitrogen was negative. The positive correlation between SiAP and total nitrogen occurs because the SiAP can increase the activity of microorganisms involved in the N and P cycle in paddy soils (Liang et al, 2021). The relationship between SiAP and soil pH is positive, meaning that an increase in soil pH will increase the SiAP concentration.…”

Silicon (Si) is a beneficial element for rice plants. However, evaluating the Si availability status of paddy soil is rarely done. This study aimed to investigate the Si availability for plant (SiAP), spatial distribution, SiAP correlations with some soil properties and the effect of SiAP status on the rice yield. This study used a survey method to collect paddy soil and water sample. The pot experiment method was used to evaluate paddy plant response to SiAP level. Based on K-means, cluster analysis showed that soil SiAP was categorized low (< 147 mg SiO2 kg-1), moderate (147 – 224 mg SiO2 kg-1) and high (> 224 mg SiO2 kg-1). The SiAP status of the paddy soil area of 26,395 hectares (25%), 61,744 hectares (59%) and 15,952 hectares (15%) was categorized as low, moderate and high, respectively. This present study revealed that the upland area paddy soil has higher SiAP than the lowland area. Total silicon dioxide (SiO2) and clay percentage were negatively correlated with the SiAP in soils. Silicon addition to the paddy soil with SiAP status showed low to high increase in rice yield by 0.2%, 3.9% and 2.7%.

This review describes the role of silicon (Si) in plants. Methods of silicon determination and speciation are also reported. The mechanisms of Si uptake by plants, silicon fractions in the soil, and the participation of flora and fauna in the Si cycle in terrestrial ecosystems have been overviewed. Plants of Fabaceae (especially Pisum sativum L. and Medicago sativa L.) and Poaceae (particularly Triticum aestivum L.) families with different Si accumulation capabilities were taken into consideration to describe the role of Si in the alleviation of the negative effects of biotic and abiotic stresses. The article focuses on sample preparation, which includes extraction methods and analytical techniques. The methods of isolation and the characterization of the Si-based biologically active compounds from plants have been overviewed. The antimicrobial properties and cytotoxic effects of known bioactive compounds obtained from pea, alfalfa, and wheat were also described.
