Background
Efficient application of organic fertilizers contributes to resource-efficient agriculture. Acidification of liquid manure effectively reduces ammonia (NH3) emissions. However, the effect of acidification on other plant nutrients, such as Mn, often a yield-limiting nutrient in cereal production, is not well understood.
Aims
This study aimed to investigate the effect of fertilization with acidified biogas residues (ABGR) on yield, Mn concentration, and Mn uptake from winter wheat.
Methods
A fully randomized field trial with winter wheat was established on a sandy/loam soil in northern Germany in 2016 and 2017, with sowing each September and harvest in the following year. Fertilizer treatments of untreated biogas residues (UBGR) and ABGR, respectively, were applied on NH4+-N basis. The effects of UBGR application at three NH4+ fertilization levels were compared with each other and with three corresponding ABGR fertilization levels. Yield, Mn concentration, and Mn uptake were determined at the early milk stage during intermediate sampling and again at final harvest before the early dough stage.
Results
Fertilizing with ABGR increased yield and Mn uptake at early dough stage under low fertilizer rates in both years. However, grain yield was significantly increased by ABGR application in the first year only. Significant increases in Mn concentrations were observed at the two higher fertilizer levels as a result of ABGR application.
Conclusions
Fertilizing with ABGR has the potential to improve Mn uptake by cereals. This yield-limiting factor could therefore be minimized by acidification, especially in years with low rainfall, when Mn deficiency is frequently observed.

Background
Previous research has underscored the importance of evaluating soil consistency for accurate determination of cohesive character and mechanical properties. Although qualitative assessments by pedologists are pertinent, they exhibit inherent subjectivity that may compromise accuracy. This variability fosters the adoption of quantitative methods, such as dynamometer measurements, to enhance objectivity.
Aims
This study compared the variability in dry-soil consistency assessments performed by pedologists with quantitative evaluations obtained using a dynamometer to establish tensile strength ranges corresponding to distinct consistency classes.
Methods
Soil samples from two Alfisols, differing in cohesive character, were collected from the Bt horizon at top, middle, and base positions. The focus was on aggregates ranging from 19 to 25 mm in diameter. Three pedologists conducted qualitative evaluations of 90 aggregates per horizon, whereas a dynamometer provided quantitative measurements. The results were subjected to exploratory and experimental statistical analyses, including variance analysis (F test) and Tukey's mean comparison test, with assessment of data normality. To determine tensile strength for extremely hard consistency, the average percentage of aggregates classified in the highest cohesion class by pedologists was applied to the dynamometer data, thereby establishing a lower tensile strength limit, a method extended to other consistency classes.
Results
Pedologists’ assessments exhibited variability between 8% and 37% for one soil type and 0%–23% for the other, with dynamometer data reflecting similar variability. A threshold of 50 kPa was identified as indicative of cohesive soil character.
Conclusion
The findings indicate that integrating tensile strength ranges with pedological evaluations significantly mitigates subjectivity.

Poor crop establishment caused by Fe toxicity hinders the adoption of direct-seeded rice cultivation in Fe-rich soil. To date, there have been few reports on the genotypic variation in rice's Fe tolerance during the pre-establishment period (i.e., germination and emergence).
Aims
The objectives of this study were to elucidate the germination and seedling vigor of diverse cultivars under various Fe levels, and to identify rice genotypes that can tolerate Fe stress during the pre-establishment period.
Methods
We evaluated 19 genotypes, including japonica, indica, and aus accessions, in hydroponic culture, under Fe stress imposed from 0 to 30 days after sowing.
Results
High Fe (500 mg Fe2+ L−1) did not affect germination in any genotype. However, 50 mg Fe2+ L−1 retarded and reduced both shoot and root growth, 200 mg Fe2+ L−1 caused partial mortality, and 400 mg Fe2+ L−1 was fatal to plants after germination. We found significant genotypic variation in shoot growth under Fe stress. Two indica genotypes, “Pokkali” and “Cilamaya Muncul”, had the highest tolerance to high Fe, attributable to limited Fe accumulation in shoots, mainly due to high root Fe retention. “Pokkali” also had high Fe content per unit root weight in the Fe plaque under moderate Fe stress, suggesting the potential contribution of vigorous formation of a root Fe plaque to rice's Fe tolerance.
Conclusions
The study identified promising Fe-tolerant donor genotypes for future rice breeding. We suggest that limiting Fe accumulation in shoots is important under high Fe stress during establishment.

Background
Biochar shows a positive effect on soil properties and indigenous microbial communities in farmland; meanwhile, long-term effects of biochar on native soils are poorly understood.
Aims
This research aimed to dissect the inherent relationships between soil physicochemical properties and microorganisms following the application of biochar under different nitrogen fertilization rates.
Methods
Thus, a 2-year field trial, including four different consecutive crops, was performed to investigate the effect of biochar amendment with nitrogen fertilizer addition on soil properties and microbial community.
Results
Biochar exerted a significant influence on soil pH, bulk density (BD), and soil organic matter (OM) content. The soil quality index area was not significantly affected by biochar and nitrogen fertilizer. Biochar application increased the total phospholipid fatty acid (PLFA) contents from 16.34–17.51 to 36.74–58.49 nmol g−1, whereas bacterial, fungal, Gram-negative bacterial, and Gram-positive bacterial increased by 2.4–4.3, 2.1–3.9, 1.1–4.0, and 1.6–2.3-folds, respectively. The Shannon–Weiner diversity index increased by 4.7%–26.4%, Simpson index increased by 13.3%–18.4%, whereas the Pielou index decreased 9.7%–22.4% with the biochar amendments. Partial least squares path modeling results revealed that biochar and nitrogen fertilizer indirectly influenced both soil PLFA contents and alpha diversity through their effects on OM contents, BD, and mineral nitrogen availability.
Conclusions
In conclusion, the 2-year field trial shows that biochar amendment, combined with different nitrogen rates, significantly impacts soil properties. Notably, it enhances soil microbial PLFA contents and diversity, suggesting its potential for long-term soil health improvement.

Mucilage is vital for rhizosheath formation, the soil adhering to plant roots after gentle shaking. We hypothesized that alternating drying-wetting cycles affect mucilage's role in rhizosheath development and soil aggregation within the rhizosphere.
Methods
To explore this, we employed flax cord as an artificial root model, subjecting it to soils with varying clay contents (22% and 32%), both sterilized and unsterilized. We moistened the model roots with 0.12% w/w (grams of dry chia seed mucilage per gram of water) and incubated them under controlled conditions. Soil moisture levels were maintained at 75% of water holding capacity (reference) and subjected to five dry–wet (DW) cycles, mimicking wet–dry fluctuations. Subsequently, we isolated the rhizosheath through gentle shaking and analyzed surrounding soil particle-size distribution and aggregate properties using laser diffraction and scanning electron microscopy (SEM).
Results
Remarkably, constant wet conditions had more pronounced impact, significantly enhancing rhizosheath development, particularly in unsterilized soil with 22% clay. Conversely, DW cycles led to a notable reduction in rhizosheath compared to the wet treatment, likely due to physical interactions affecting rhizosheath formation. Notably, there were minimal treatment effects on particle aggregation outside the rhizosheath, with an average diameter of <10 µm and limited influence from the water regime.
Conclusions
We conclude that water regime emerged as the key factor influencing mucilage's contribution to rhizosheath formation, whereas clay content and microbial activity played minor roles in this simple model that represent a complex and dynamic biological system.

Background and Aims
The use of phosphorus (P) fertilizers reduces the availability of silicon (Si) in soils, especially in crops such as rice and maize that have a high Si demand. This study conducted three experiments to examine P–Si interactions, Si's impact on P uptake, and the potential of Nano-Si and two types of Nano-Si (NanoLig-Si and NanoSel-Si) as alternative Si sources.
Methods
Nano-Si materials were characterized using scanning electron microscopy (SEM), XRD, and Fourier transform infrared (FTIR). Three experiments were conducted: (1) the effect of increasing P levels on Si concentration in barley and wheat; (2) the impact of Nano-Si and Na-Silicate on P and Si nutrition in maize; and (3) the influence of Nano-Si, NanoLig-Si, and NanoSel-Si on P and Si nutrition in rice under soil and hydroponic conditions.
Results
Applied P reduced the Si concentration in barley from 5.53 to 2.18 g kg−1 and in subsequently grown wheat from 9.07 to 5.05 g kg−1. Both Si sources significantly increased P concentrations, whereas only Nano-Si treatment had a positive effect on the Si concentration of maize. In soil, Si treatments did not affect rice P concentrations. In hydroponics, P increased with Nano-Si and low composite doses, whereas Si increased with Na-silicate and high doses of NanoSel-Si and NanoLig-Si.
Conclusions
These results reveal crop- and system-specific P–Si interactions. Although high P reduced Si uptake in barley and wheat, Si sources enhanced P uptake. Nano-Si materials were most effective in boosting P and Si uptake in soilless systems.
背景与目的磷肥的使用降低了土壤中硅（Si）的有效性，特别是在水稻和玉米等对硅有高需求的作物中。本研究进行了三个实验来研究P -Si相互作用，Si对P吸收的影响，以及纳米Si和两种类型的纳米Si （nanoligi -Si和NanoSel-Si）作为替代硅源的潜力。方法采用扫描电镜（SEM）、x射线衍射（XRD）和傅里叶变换红外（FTIR）对纳米硅材料进行表征。进行了3项试验：(1)提高磷水平对大麦和小麦中硅含量的影响；(2)纳米硅和硅酸钠对玉米磷硅营养的影响；(3)土壤和水培条件下纳米硅、纳米oligo -Si和纳米sell -Si对水稻磷硅营养的影响。结果施磷使大麦的硅浓度从5.53 g kg - 1降低到2.18 g kg - 1，随后生长的小麦的硅浓度从9.07 g kg - 1降低到5.05 g kg - 1。两种硅源处理均显著提高了玉米的磷浓度，而只有纳米硅处理对玉米的硅浓度有正影响。在土壤中，硅处理对水稻磷浓度没有影响。在水培中，磷随着纳米硅和低复合剂量的增加而增加，而硅随着钠硅酸盐和高剂量的纳米硅和纳米硅而增加。这些结果揭示了作物和系统特异性的磷硅相互作用。虽然高磷降低了大麦和小麦对硅的吸收，但硅源促进了对磷的吸收。在无土系统中，纳米硅材料在促进磷和硅吸收方面最有效。

Determination of the precise quantity of plant-available phosphorus (P) is imperative to ensure a sufficient supply of nutrients to plants. As a basis for this, the preparation of soil samples has been shown to exert a substantial influence on the extractability of nutrients. To clarify the effects of drying time and temperature of soil samples, water extracts are used with subsequent determination of organic and inorganic P, leading to the finding that an increase in water-extractable P during the drying process cannot be solely attributed to the decrease in soil water content. Furthermore, we observed that higher temperatures result in an increase of water extractable P, up to a temperature between 40°C and 105°C. However, it is crucial to note that the temperature effects on water-extractable P differ between organic and inorganic P forms. High temperatures during transport, storage, or sample preparation should be avoided to ensure comprehensive interpretation of results and precise fertilizer recommendations.

Modern intensive agriculture to feed the growing population of the world has been practiced in view of the limitations of arable land and water resources. However, overapplication of chemical fertilizers may pose severe environmental impacts, including soil degradation, water eutrophication, and pollution of groundwater. One of the current trends to reduce the adverse effects of fertilizers is the application of nanotechnology, which has an exciting potential to increase fertilizer efficiency and sustainability. We carried out a systematic literature review through Web of Science and Scopus. The used keywords were “nanofertilizers,” “phosphorus nanoparticles,” “nutrient-use efficiency,” and “crop development.” Only studies that meet strict inclusion criteria regarding synthesis, application, plant uptake mechanism, and detailed insight into nanofertilizers were considered. To better understand the conditions that most foster nanofertilizer application, we reviewed the factors affecting nutrient-use efficiency in plants. On this basis, focusing on phosphorus (P), we analyzed recent progress made on using P nanofertilizers and their effect on the development of various crops. The economic and environmental benefits and drawbacks of using nanofertilizers are both presented to make informed decisions by both farmers and industries on the use and manufacturing of the substances. Our review has established that nanofertilizers hold great promise for improving nutrient-use efficiency and crop productivity, with special mention of phosphorus nanofertilizers, which can offer improved nutrient uptake, reduced environmental pollution, and possibly reduced fertilizer application rates. However, P nanofertilizers face adoption barriers such as unstudied long-term environmental impacts, costly and unsustainable production methods, inconsistent performance across soils and crops requiring tailored formulations, and lack of regulations and safety guidelines. Transitioning to practical use demands prioritized research using long-term trials and affordable green synthesis methods to address these gaps.
考虑到耕地和水资源的限制，为养活不断增长的世界人口而实行了现代集约化农业。然而，化肥的过量施用可能会造成严重的环境影响，包括土壤退化、水体富营养化和地下水污染。目前减少肥料不良影响的趋势之一是纳米技术的应用，纳米技术在提高肥料效率和可持续性方面具有令人兴奋的潜力。我们通过Web of Science和Scopus进行了系统的文献综述。使用的关键词是“纳米肥料”、“磷纳米颗粒”、“养分利用效率”和“作物发育”。仅考虑在合成、应用、植物吸收机制和详细了解纳米肥料方面符合严格纳入标准的研究。为了更好地了解最有利于纳米肥料施用的条件，本文综述了影响植物养分利用效率的因素。在此基础上，以磷(P)为重点，分析了近年来磷纳米肥料的应用进展及其对各种作物生长的影响。使用纳米肥料的经济和环境效益以及缺点都被提出，以便农民和工业就这些物质的使用和制造做出明智的决定。我们的综述表明，纳米肥料在提高养分利用效率和作物生产力方面具有很大的前景，特别是磷纳米肥料，它可以提高养分吸收，减少环境污染，并可能降低施肥量。然而，纳米磷肥面临着采用障碍，如未经研究的长期环境影响、昂贵且不可持续的生产方法、不同土壤和作物的性能不一致，需要量身定制配方，以及缺乏法规和安全指南。向实际应用过渡需要优先研究，使用长期试验和负担得起的绿色合成方法来解决这些差距。
