“…Assessing zinc absorption of three different fertilizers (ZnSO4.7H2O, Zn(NO3)2, and Zn-EDTA) via foliar fertilization on citrus trees for 4 years, Boaretto et al (2023) demonstrated that nitrates were +113% and +214% more efficient than sulfate and EDTA, respectively. These authors had to decrease the concentration of zinc nitrate applied to plants to half of the dose used in the fourth year of the experiment due to leaf scorching.…”

“…Copper, for instance, when applied in equal amounts via a nitrate-based source was more toxic than the same amount applied via sulfate (Mohanapriya, Senthilkumar, Sivakumar, Dineshkumar, & Subbhuraam, 2006). As nitrates are more efficient than sulfates for foliar/root absorption, similar concentrations of cations applied through these different sources cause different levels of toxicity (Boaretto et al, 2023).…”

“…Zn-EDTA was the least efficient for the foliar application of zinc in citrus plants. Pure zinc nitrate and sulfate were +214% and +47% more efficient than Zn-EDTA (Boaretto et al, 2023). Conversely, humic-stabilized nano-ferrihydrite (FH) particles were 70 to 75% more effective than Fe-EDTA via foliar fertilization in wheat (Zimbovskaya et al 2020).…”

When considering foliar fertilization, many questions arise about the differences between chelation, complexation, and their efficiency in supplying nutrients to plants. How efficiently are chelated and complexed nutrients absorbed by plants? Are chelates and complexes absorbed by plants? How do they perform in foliar and soil applications? Do they exhibit greater efficiency when compared to pure inorganic fertilizers? and, which ones are the best: soluble, sparingly soluble, or insoluble inorganic fertilizers? Although many people believe chelation and complexation are similar, some differences must be considered when choosing products to better supply plants with nutrients, avoid problems with tank mixtures, and enhance plant nutrition efficiency. The same is true for the vast variety of inorganic sources of fertilizers available for agriculture. They do not behave the same. For instance, inorganic water-soluble fertilizers such as nitrates, sulfates, and chlorides present different performances and should be chosen not only based on their nutrient concentration, availability, and price. All this information will assist farmers and technicians in better defining and selecting products to improve sustainability, efficiency, and achieve better results.

The control of irrigation volume is of significant importance in arid regions of northwest China. Particularly, it has a crucial impact on the salinization of shallow groundwater areas. In 2022 and 2023, field experiments were conducted to test three distinct under-membrane irrigation treatments. These treatments were assigned water quotas of HW (27 mm), MW (22.5 mm), and LW (18 mm). The HYDRUS-2D model was integrated with a field experiment to accurately simulate the dynamic fluctuations of soil water and salt in the sunflower root zone. The model’s performance was assessed and verified using real-field data from 2022 and 2023, and the simulation results closely matched the measured values. This research also used stable hydroxide isotopes to assess the water supply from various soil layers at different time intervals in sunflower plants. The results indicated that the three different levels of irrigation applied under the membrane had a significant impact on soil water content. Specifically, there was a significant difference in soil water content at a depth of 0–40 cm (p < 0.05), while there was little effect on the water content at a depth of 40–60 cm (p > 0.05). After irrigation, the average salt content in the top 0–20 cm of soil decreased by 7.0% compared to the medium and low irrigation levels, and by 10.8% compared to the medium irrigation level. Additionally, the medium irrigation level resulted in a 10.8% decrease in salt content compared to the low irrigation level, and a 4.1% decrease compared to the medium irrigation level. During the same period, the soil salinity levels at depths of 0–20 cm, 20–40 cm, 40–60 cm, and 60–100 cm in the area outside the membrane were measured to be 2.7~4.8 g·kg−1, 2.8~4.0 g·kg−1, 2.7~3.4 g·kg−1, and 1.7~2.6 g·kg−1, respectively. These levels decreased by 13.1~55.5%, 0.7~42.8%, −0.4~16.2%, and −72.7~7.5%, respectively. Following irrigation, the HW treatment mostly absorbed water in the 0–40 cm soil layer, while the MW and LW treatments absorbed water in both the 0–40 cm and 60–80 cm soil levels. The results indicated that the most optimal drip irrigation method beneath the membrane in this location was achieved when the amount of water applied was between 25–30 mm. This method demonstrated a combination of water conservation, high crop yield, and effective salt suppression.
