Special Issue Information

Dear Colleagues,

Climate change has been impacting food production, which should be increasing to meet the growing population's demand. To increase food production, it is essential to study the behavior of the soil–wetland–water relationship, and the definition and description of the elements of this system are crucial. Water plays a fundamental role within this system, as it is directly related to the transport of solutes, photosynthesis, growth, and productivity. Associated with this, its interaction with the soil can affect root development and uptake of nutrient; therefore, understanding how the ground affects the dynamics of the plant is essential to maintain productivity. Additionally, the relationship with the plant can suffer stress due to several factors, such as the unavailability of water, soil compaction, and salinity, among others.

Magnesium (Mg) ions play a crucial role in the growth and development of tea plants (Camellia sinensis). In this study, the ion kinetic method was used to analyze the effect of ions from various elements on the Mg ion uptake rate in two tea plant varieties (Rougui and Shuixian). Additionally, Mg ion content and the expression intensity of CsMGT5 gene in the tea plant’s root system were measured to further understand how different elemental ions affect Mg ion uptake and accumulation. The results revealed that while the trends in the effects of different elements on Mg ion uptake were similar in both Rougui and Shuixian roots, the magnitude of these effects was lower in Rougui and higher in Shuixian. In the presence of only Mg ions in the solution, the tea plant’s root system exhibited the highest intensity of CsMGT5 gene expression, the fastest uptake rate of Mg ion, and the highest Mg content. Conversely, the presence of nitrogen, phosphorus, and potassium ions alone reduced CsMGT5 gene expression, Mg ion uptake rate, and Mg content in the tea plant’s root system. However, differences in the impact of these three elements on Mg ion uptake and accumulation were not statistically significant. In addition, with the increase in the types of added ions, the Mg ion uptake rate by tea plants gradually declined, indicating a decreasing demand, with Mg accumulation showing a downward trend. Statistical analysis of correlations showed that CsMGT5 gene expression in the tea plant’s root system positively regulated the maximum uptake rate of Mg ion (Imax value, 0.94 **). The Imax value negatively regulated Mg ion content in solution (Cmin value, −0.94 **), and the Cmin value negatively regulated Mg ion content in the tea plant’s root system (−0.95 **). In conclusion, the presence of different elemental ions significantly influenced the uptake and accumulation of Mg ions in tea plants, with the magnitude of this effect intensifying as the number of elemental types increased. A positive correlation was observed between the capacity for Mg ion uptake and accumulation capacity in the tea plant’s root system and the expression intensity of the CsMGT5 gene within the root system. This study offers valuable insights and serves as an important reference for leveraging Mg to regulate tea plant growth in practical agricultural applications. Full article

Increasingly frequent and severe droughts pose significant threats to forest ecosystems, particularly affecting photosynthesis, a crucial physiological process for plant growth and biomass production. This study investigates the impact of phosphorus fertilization on the photosynthesis of common beech (Fagus sylvatica L.) and sessile oak (Quercus petraea (Matt.) Liebl.). In a common garden experiment, saplings originating from two provenances (wetter KA and drier SB provenances) were exposed to regular watering and drought in interaction with moderate and high phosphorus concentrations in the growing substrate. Results indicated that drought significantly reduced pre-dawn leaf water potential (ΨPD), net photosynthesis (Anet), stomatal conductance (gs) and photosynthetic performance index (PIabs) in both species. Phosphorus fertilization had a negative impact on Anet and PIabs, thus exacerbating the negative impact of drought on photosynthetic efficiency, potentially due to excessive phosphorus absorption by saplings. Provenance differences were notable, with the KA provenance showing better drought resilience. This research highlights the complexity of nutrient–drought interactions and underscores the need for cautious application of fertilization strategies in reforestation efforts under changing climatic conditions.

In regions where water is a limited resource, lettuce production can be challenging. To address this, water management strategies like deficit irrigation are used to improve water-use efficiency in agriculture. Associating this strategy with silicon (Si) application could help maintain adequate levels of agricultural production even with limited water availability. Two lettuce crop cycles were conducted in a completely randomized design, with a factorial scheme (2 × 3), with three irrigation levels (60%, 80% and 100%) of crop evapotranspiration (ETc), and with and without Si application. To explore their combined effects, morphological, productive, physiological and nutritional parameters were evaluated in the crops. The results showed that deficit irrigation and Si application had a positive interaction: lettuce yield of the treatment with 80% ETc + Si was statistically similar to 100% ETc without Si in the first cycle, and the treatment with 60% ETc + Si was similar to 100% ETc without Si in the second cycle. Photosynthetic rate, stomatal conductance, intercellular CO2 concentration, transpiration rate and total chlorophyll content increased under water-stress conditions with Si application; in the first cycle, the treatment with 80% ETc + Si increased by 30.1%, 31.3%, 7.8%, 28.46% and 50.3% compared to the same treatment without Si, respectively. Si application in conditions of water deficit was also beneficial to obtain a cooler canopy temperature and leaves with higher relative water content. In conclusion, we found that Si applications attenuate water deficit effects and provide a strategy to ameliorate the yield and water productivity in lettuce crops, contributing to more sustainable practices in agriculture.

Soil management systems can directly interfere with crop yield via changes in the soil’s physical and hydraulic properties. However, short- to medium-term experiments of conduction do not always demonstrate the modifications of the management systems in these properties. Thus, the aim of this study was to evaluate the physical properties of the soil in a long-term management system and to relate it to the storage and availability of water to plants, verifying its effect on soybean yield. The experiment was conducted in randomized blocks in a split-plot scheme with four replications. Plots were composed by soil management (conventional tillage and no-tillage), and subplots represented three soil depths (0.0–0.1, 0.1–0.2, and 0.2–0.4 m). The soil’s physical and hydraulic properties, root development, and soybean yield were evaluated. The no-tillage system not only presented higher bulk density and soil resistance to compaction up to a depth of 0.2 m but also greater root development. This management also did not affect the process of water infiltration in the soil and presented an increase in soybean grain yield by 6.5%. The long-term no-tillage system (33 years) offers less risk of water stress to soybean plants; it contributes to greater grain yield of this crop when compared to the conventional tillage system.
