Background and aims In highly weathered soils of central Amazonia, where nutrients such as phosphorus (P) and base cations are scarce, fertilization experiments have demonstrated above- and belowground effects on total net primary productivity (NPP). This study examined how fine root stocks and turnover responded to added nutrients over a two-year period. We predicted that adding a limiting nutrient would decrease fine root stocks and increase turnover, with the strongest effects from P, followed by base cations, and no response to N. Methods Fine roots (< 2 mm diameter) were sampled from the 0–30 cm soil layer in a low-fertility primary forest in central Amazon subjected to a large-scale factorial experiment adding P, base cations, and N over two years. Fine root turnover was calculated as the ratio between fine root productivity, measured with in-growth cores, and fine root stock. Results Fine root stocks remained unchanged with nutrient addition. However, P increased root turnover by 23% and 48% in the first and second years, respectively, while base cations addition reduced turnover by 24% in year two. N had no significant effect, though a trend toward reduced turnover was observed in the second year. Conclusion The results of this study show that fine root standing stock and turnover in the central Amazon are regulated by soil nutrient availability, especially P and base cations. The contrasting responses observed suggest distinct belowground resource-use strategies for different nutrients, shaped by the nutrient specific mobility in the soil and physiological role in the plant.

Background and Aims Potassium (K) is a key macronutrient that regulates diverse metabolic processes, yet K-deficiency is widespread in tropical crops because the underlying soils are inherently low in natural fertility. However, the high price of K-fertilizer constrains application rates, challenging efforts to sustain productivity within economically and environmentally sustainable systems. Increasing evidence indicate that K can be partially substituted by sodium (Na), which represents a cost-effective strategy to alleviate K deficiency while enhancing soil fertility and plant resilience. This review explores the physiological mechanisms, crop-specific potential, environmental implications, and agronomic feasibility of partially replacing K with Na, highlighting promising pathways toward more sustainable fertilization strategies in tropical agriculture. Outcomes Partial substitution of K with Na can provide physiological, environmental, and economic benefits, particularly in tropical systems. Sodium can partially sustain turgor, stomatal function, and enzyme activity in K-deficient plants, supporting photosynthesis and biomass accumulation, especially under drought. Economically, sodium chloride (NaCl) is more affordable than potassium chloride (KCl), while environmentally, its use can reduce reliance on non-renewable K sources and valorize industrial residues. Nonetheless, species-specific tolerance limits its broad application and risk of soil salinization is still uncertain under tropical conditions. Field experiments are therefore essential to establish safe, crop-specific guidelines, supporting sustainable and cost-effective fertilization strategies. Final Consideration Recognizing Na as a context-dependent co-nutrient allows for innovative, crop-specific fertilization strategies that improve agronomic efficiency, reduce costs, and promote environmental sustainability. However, the risks of soil salinization and variability in species tolerance underscore the need for long-term field studies to define safe application thresholds.

Background The holobiont" refers to the plant and its associated microbiota that are pivotal to the plant's health, fitness, and survival. By in vitro culturing and functionally characterizing members of the plant microbiota, their specific roles in influencing plant responses to environmental changes can be determined and manipulated to foster sustainable agriculture and ecosystem management. Aims The review presents a comprehensive survey and current updates on culturomics of plant microbiota within the overall context of: a) the importance of understanding the plant holobiont composition and functioning; b) the necessity to in vitro track down and explore environmental microbiomes, entailing the plant microbiome with its myriad composition and spatio-temporal dynamics and mobility in various plant species, compartments and growth stages and c) the recent developments of the emerging in-situ similis cultivation strategies grounded on plant-based culture media. Conclusions The review highlights the urgent need to explore in vitro cultivation strategies built on compatible plant-based culture media, and the transformative role of omics technologies in refining these strategies. By bridging fundamental research and cultivation-based applications, such tools offer a gateway towards more sustainable and efficient in vitro cultivation systems, leading to a deeper understanding and potential manipulation of the plant holobiont.
