Methods: These goals were achieved through (i) a histochemical study of Cd localization in pea roots, (ii) spectrophotometric determination of pectin content and the activity of pectin methylesterase (PME), (iii) speciation of Cd extracted from pea roots conducted through size exclusion chromatography (SEC) and inductively coupled plasma mass spectrometry (ICP/MS). Results: Cd was found mainly in the root stele of the Cd-stressed plants. The pectin content and PME activity were lower in the Cd-stressed plants, but Si supplementation reversed these effects. Selectivity was noticed in Cd extraction efficiency with water being the least effective and enzymatic-assisted extraction proving to be the most effective. Speciation analysis revealed significant heterogeneity in molar mass, ranging from approximately 295 to 95 kDa. Galacturonic acid was identified the dominant species responsible for Cd binding. The choice of solvent for extraction markedly influenced the Cd binding profile, indicating shifts in the distribution of species’ molar mass and their relative concentrations in extracts. Conclusions: Si alleviates Cd toxicity in pea plants, and one of the mechanisms through which it operates involves increasing pectin levels and PME activity. Pectin plays an active role in Cd detoxification in the root cell walls, forming electrostatic bonds with Cd cations through its carboxyl groups.</p>","PeriodicalId":17042,"journal":{"name":"Journal of Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141613791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biochar, containing various elements such as carbon, nitrogen, and phosphorus, possesses a porous structure with strong adsorption capabilities. This characteristic renders it useful for ameliorating acidic soils, influencing soil nitrogen cycling, and mitigating greenhouse gas emissions. To quantitatively analyze the diverse impacts of different biochar on soil nitrogen cycling and to highlight its implications for sustainable agriculture, this study collected 155 relevant articles and conducted a comprehensive meta-analysis. The results indicate that biochar can elevate the pH by 4.60% for acidic soils and significantly increase soil organic carbon content by 64.60%. Different feedstocks, such as Wooden Biochar (WB), Crop Husk (CH) Biochar, Crop Straw Biochar (CS), and Organic Waste Biochar (OW), exhibit distinct effects, with WB and OW showing the most significant increases in SOC. Pyrolysis temperature is also a critical factor, and biochar produced at medium and high temperatures enhances pH more effectively than low-temperature biochar. Additionally, biochar enhances the abundance of the nitrogen functional gene <i>amoA-</i>AOB by 25.58%, promoting ammonia oxidation, reducing ammonia (NH₃) emissions by 16.39%. Experimental setups also influence outcomes that biochar application in woods and incubation studies significantly reduced nitrous oxide (N₂O) emissions compared to pot and field experiments. The findings suggest that adding biochar to soil accelerates nitrogen cycling, thereby reducing greenhouse gas emissions. The results advocate biochar’s use in sustainable soil management practices.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>","PeriodicalId":17042,"journal":{"name":"Journal of Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141586259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, few studies have investigated the impact of Si application on the growth and fruit quality of cherry tomatoes, leading uncertainty regarding whether Si application can improve cherry tomato yields and quality under N imbalance. In this study, we performed a pot experiment with cherry tomato plants, and used two N fertilizer inputs (high N level, 0.40 g N kg^− 1 soil; low N level, 0.20 g N kg^− 1 soil) with or without Si application, to investigate the influence of Si application on plant growth, photosynthesis, leaf N metabolic enzyme activities, and fruit quality in cherry tomatoes under N imbalance. This study aimed to assess the promotive effects of Si application on the growth and fruit quality of cherry tomatoes under nitrogen (N) imbalance. The results showed that Si application enhanced dry matter accumulation and photosynthesis, regardless of the N conditions. Compared with treatment without Si application, the total dry matter accumulation, net photosynthetic rate, stomatal conductance, and transpiration rate were enhanced by 2.59%, 3.76%, 23.9%, and 17.1% under low N conditions, and by 7.50%, 26.2%, 49.1%, and 26.3% under high N conditions, respectively. Furthermore, Si regulated the activities of leaf N metabolic enzymes, increasing the N content of the plant under low N conditions and decreasing it under high N conditions. Si application improved fruit quality, as the vitamin C content and firmness were increased by 13.2% and 3.57% under low N conditions and by 7.09% and 17.4% under high N conditions, respectively.

Additionally, there’s an increasing urgency to explore alternative P sources to enhance agricultural productivity and sustainability because P sources are finite. The objectives of this study were to compare the agronomic effectiveness of struvite (Est), organomineral (OM), and thermophosphate (ThermoP) with triple superphosphate (TSP) in increasing maize yields in sandy loam and clayey tropical soils. Investigate the effects of alternative phosphorus fertilizers on the phosphorus use efficiency of maize over two consecutive cropping cycles. Determine the feasibility of these alternative phosphorus sources as replacements for conventional TSP to promote sustainable nutrient management practices in agriculture. In a greenhouse, sandy loam and clayey soils were fertilized with four P sources: OM, Est, ThermoP, and TSP. Two successive maize crops were grown, with each treatment receiving a P rate of 100 mg kg^− 1. Soil and plant chemical analyses were carried out and then the following fertilizer efficiency indices were calculated: agronomic efficiency index (AEI), agronomic efficiency (AE), crop recovery efficiency (CE), phosphorus utilization efficiency (PUE), P recovery efficiency (PUpE), and physiological efficiency (PE). Est and OM had higher agronomic efficiencies than TSP in sandy soils. The alternative sources exhibited almost 2-fold more efficiency in the sandy loam compared to the clayey soil. The superior performance of Est was attributed to its slow nutrient release and physicochemical properties that potentially improve soil quality. Regarding PE, OM and TSP led the highest values in both cultivations in sandy loam soil. In the 1st crop cycle, the average PE of these two treatments was ∼ 215 g g^− 1 while in the 2nd the average was ∼ 181 g g^− 1. The Est fertilizer resulted in the highest values of CE, PUpE, and PUE.

The study included four levels of banana pseudostem-based co-compost (BPC), viz., CF: control (100% recommended chemical fertilizers); C₅: 5 t ha⁻¹; C₁₀: 10 t ha⁻¹; C₁₅: 15 t ha⁻¹; and three foliar frequencies of banana pseudostem sap (BPS), WFS: without application; 2TFS: two; and 3TFS: three times. The treatments were repeated three times, followed by the factorial completely randomized block design. Increasing the dose of compost and foliar sap improved corn growth, yield, and quality. Compared to chemical fertilizers, soil amendment with BPC significantly improved N (7.31%) and P (19.4%) uptake, corn yield (10.6%), and 11.4%, biomass in the 15 t ha⁻¹ compost-treated pot. Similarly, the three foliar sprays of BPS separately increased on average by 8% and 6.5% of cob yield and biomass, respectively over the non-spraying treatment.

Therefore, increasing awareness regarding SOM and agricultural sustainability was regained importance in the farming community. The build-up of SOM triggers to chemical transformations of macro, micro, and secondary nutrients in the soil. The SOM is a rich source of secondary nutrients, and its slow release contributes to the dynamics in soil nutrient levels. Integrated use of OM application with mineral fertilizers increased soil organic carbon (SOC) more efficiently and enhanced nutrients in the soil. The present study showed that the build-up of OM affected macro, micro, and secondary nutrients differently. The detailed review of previous research studies concluded that the build-up of OM showed a strong positive correlation with nitrogen, phosphorus, potassium, zinc, manganese, iron, and sulphur availability. However, in some cases, OM build-up demonstrated a negative correlation with copper, calcium, and magnesium availability. Thus, the present review focused on soil’s critical role of serving as a complex ecosystem that regulates numerous functions for sustainable agricultural production through nutrient cycling.
