The improvement of soybean root rot by BC was very weak, and the application of 45 t·ha⁻¹ BC could reduce soybean root rot by about 7% only. Compared with the BC treatment, the disease index of 30KBC and 45KBC was 22.17% and 19.82% less than CK, respectively. High application rates of BC and KBC increased the aeration, bacterial abundance and diversity of soybean rhizosphere soil, and improved the proportion of soil nutrients. The 30KBC and 45KBC significantly increased the relative abundance of beneficial bacteria (<i>Acidobacteria, Mortierellomycota, Pseudomonas, Chryseolinea, Lysobacter and Mortierella</i>) and decreased that of pathogenic bacteria (<i>Bacteroidetes, Ascomycota and Fusarium</i>) in soil. Soybean quality indicators including oil content, K, P and protein content correspond to 30KBC. The biochar can improve soil physicochemical properties, reduce the relative abundance of pathogenic bacteria, and increase that of beneficial bacteria, thereby reducing root rot incidence and improving soybean quality. Under the condition of water saving and nitrogen reduction, 30KBC is the optimum.

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. Multivariate analysis further supported these observations. Est and OM, can effectively replace conventional TSP in maize cultivation, resulting in better plant performance and nutrient utilization. Consequently, these alternative fertilizers offer the potential for sustainable nutrient management strategies.</p>","PeriodicalId":17042,"journal":{"name":"Journal of Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141577332","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}

The nutrition provided by organic inputs might have solved some of these problems rather than solo chemical fertilizers. Therefore, a combination of soil amendment with banana pseudostem-based compost and foliar spray of banana pseudostem sap was tested to evaluate the sweet corn’s nutrient uptake, yield, and quality. 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. In contrast, the interaction effects of BPC (15 t ha⁻¹) and foliar spray of BPS (three times) also significantly increased K, Ca, and Mg uptake by 120, 844, and 1823%, respectively, compared with those of the control. Consequently, the phenolic and total sugar content increased by 16.21% and 7.28%, respectively in BPC (15 t ha⁻¹) related to the response of sole chemical fertilizers.

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.

In this study, we assessed the suitability of sheep manure-based compost as a potential substrate to either partially or complete replace commercial peat in the production of lettuce (<i>Lactuca sativa</i> L.) seedlings. Methods: Five different substrate treatments were used: 100% peat (100% P) served as the control; 100% compost (100% C); 25% C/75% P; 50% C/50% P; and 75% C/25% P. The study followed a completely randomized design, with sixteen replications for each treatment level. Various parameters, including seedling emergence, seedling survival, seedling growth, seedling vigor index, Dickson’s quality index, among other variables, were analyzed. Results: Seedling emergence ranged from 87.5 to 100%, with no significant differences among the substrate treatments, suggesting that seedling emergence and initial establishment can be successfully achieved in sheep manure-based compost. For seedling growth, sheep manure-based compost, whether used alone or in combination with peat, also resulted in similar or even better outcomes as compared to the control. For example, in the 100% compost treatment, seedlings exhibited comparable diameter growth and total seedling biomass to those of the control, or 100% peat. However, seedling height was 7.6% greater in the 100% compost substrate when compared to the control, demonstrating the potential growth-promoting effects of utilizing sheep manure-based compost as a growing medium. Conclusions: During our study we found that the quality of seedlings produced in all tested substrates was similar to that of the control.
