Aim of study: Essential nutrient elements such as P, Fe, Zn, Cu, B and Mn are mostly affected by soil pH. In calcareous soils, it is often difficult to obtain a pH of 6-6.5 the optimum soil pH value of phosphorus and micronutrients, as the goal of fertilizer best management practices is to match nutrient supply with crop requirements to optimize yield while minimizing nutrient losses to the environment. Material and methods: In order to study the addition of different amounts of sulfuric acid through irrigation to minimize soil pH value, and to improve the availability of the elements on cucumbers, experiments were carried out on two types of soil textures: Silty Clay Loam (S1) and Silty Clay (S2). The sulfuric acid was applied with different concentrations (0, 0.5, 1, 3, and 5 ml L -1 ). The elements' concentration was studied at three soil depths (D1 = 0-10, D2 = 10-20 and D3 = 20-30) cm. Results: The availability of P and micronutrients primarily increased in C4D3 in S2 soil. The P in this work was a positive correlation with Zn in both soils, while it showed a negative correlation with other micronutrients (Fe, Cu, B and Mn). Element concentration in plant tissue was studied in the plant residues after harvesting. The C3 was highly effective in increasing the elements (P, Fe, Zn, Cu, B, and Mn) in plant tissues in both soils, and had a significant effect on the increase in cucumber yield. Conclusion:The values of soil pH were regularly decreased by increasing sulfuric acid. Then, the availability of the studied elements was enhanced.

“…The region has an estimated average annual yield of 52 t ha −1 , which is much lower than the genetic potential of the varieties used and the national average yield of 74 t ha −1 (CONAB 2019). Among the leading causes for the relatively low sugarcane yield are water deficit, injuries caused by pests and diseases, and low soil fertility, including the Si depletion common in tropical soils (Camargo et al 2020;Crusciol et al 2018;Diniz et al 2019;Iwanicki et al 2019;Silva et al 2019).…”

Silicon (Si) fertilization can mitigate biotic and abiotic stresses and increase the yield of sugarcane. Considering the low availability of Si in tropical soils and the large amounts of fertilizer required by Si accumulating crops, concentrated sources of Si with good solubility may lead to more profitable fertilization management. In this context, we assessed the potential of an amorphous silica-based fertilizer (ASF) on increasing the soil availability and uptake of Si by sugarcane, the growth parameters, the stalk and sugar yields, and the damage caused by stalk borer (Diatraea saccharalis F.). Additionally, Si effects on the accumulation of nutrients by sugarcane were evaluated. The field trial was carried out in a randomized block design with four replications. The ASF was applied at five rates (0, 125, 250, 500, and 750 kg ha −1 ). The evaluation of the plants was performed 12 months after planting. Silicon available content in the soil layers assessed (0.0-0.2 m and 0.2-0.4 m) increased with Si fertilization. The Si concentrations in leaves and stalks were up to 5-and eightfold higher in ASF-amended plants than the control. The Si fertilization increased N, P, K, Ca, Fe, Mn, Cu, and Zn concentrations. Sugarcane growth parameters showed a positive relationship with Si in plants; the height and stalk diameter and the dry leaf biomass were 50, 58, and 71% higher in the 750 kg ha −1 ASF compared to the control, respectively. ASF also increased the contents of fiber, total sugar, and recoverable sugar. The accumulation of Si in the stalk reduced significantly the damage caused by the stalk borer. The ASF rates increased the yield of stalks, total and recoverable sugar, and the stalk borer's resistance, having great potential to boost sugarcane performance in Si-depleted soils in northeast Brazil.

Nutrient deficiencies in soil–crop contexts and inappropriate managements are the important reasons for low crop productivity, reduced nutritional quality of agricultural produce and animal/human malnutrition, across the world. The present investigation was carried out to evaluate nutrient deficiencies of sulphur (S) and micronutrients [zinc (Zn), boron (B), iron (Fe), copper (Cu) and manganese (Mn)] in agricultural soils of India for devising effective management strategies to achieve sustainable crop production, improved nutritional quality in crops and better animal/human health. A total of 2,42,827 surface (0–15 cm depth) soil samples were collected from agriculture fields of 615 districts lying in 28 states of India and were analysed for available S and micronutrients concentration. The study was carried out under the aegis of All India Coordinated Research Project on Micro- and Secondary-Nutrients and Pollutant Elements in Soils and Plants. The mean concentrations were 27.0 ± 29.9 mg kg−1 for available S, 1.40 ± 1.60 mg kg−1 for available Zn and 1.40 ± 4.70 mg kg−1 for available B, 31.0 ± 52.2 mg kg−1 for available Fe, 2.30 ± 3.50 mg kg−1 for available Cu and 17.5 ± 21.4 mg kg−1 for available Mn. There were variable and widespread deficiencies of S and micronutrients in different states. The deficiencies (acute deficient + deficient + latent deficiency) of S (58.6% of soils), Zn (51.2% of soils) and B (44.7% of soils) were higher compared to the deficiencies of Fe (19.2% of soils), Cu (11.4% of soils) and Mn (17.4% of soils). Out of 615 districts, > 50% of soils in 101, 131 and 86 districts were deficient in available S, available Zn and available B, respectively. Whereas, > 25% of soils in 83, 5 and 41 districts had deficiencies of available Fe, available Cu and available Mn, respectively. There were occurrences of 2-nutrients deficiencies such S + Zn (9.30% of soils), Zn + B (8.70% of soils), S + B (7.00% of soils) and Zn + Fe (5.80% of soils) to a greater extent compared to the deficiencies of Zn + Mn (3.40% of soils), S + Fe (3.30% of soils), Zn + Cu (2.80% of soils) and Fe + B (2.70% of soils). Relatively lower % of soils were deficient in 3-nutrients (namely S + Zn + B, S + Zn + B and Zn + Fe + B), 4-nutrients (namely Zn + Fe + Cu + Mn) and 5-nutrients (namely Zn + Fe + Cu + Mn + B) simultaneously. The information regarding the distribution of deficiencies of S and micronutrients (both single and multi-nutrients) could be used by various stakeholders for production, supply and application of right kind of fertilizers in different districts, states and agro-ecological regions of India for better crop production, crop nutritional quality, nutrient use efficiency, soil health and for tackling human and animal malnutrition.
