“…At harvest, different zinc fractions were found in the order: water soluble plus exchangeable-Zn (WSEx-Zn) < complexed-Zn (Comp-Zn) < crystalline sesquioxide bound-Zn (CSB-Zn) < amorphous sesquioxide bound-Zn (ASB-Zn) < residual-Zn (Res-Zn) fractions. These results were in accordance with the findings of Preetha and Stalin [29], Solanti et al [30] and Spelbar et al [21].…”

“…These findings were in agreement with Wijibandara [16], Veeranagappa et al [17] and Talukdar et al [18]. Higher content of ASB-Zn fraction as compared to CSB-Zn as well as WSEx-Zn and Comp-Zn might be attributed to the greater ability of amorphous sesquioxides to adsorb zinc because of their high specific surface area [19,20] and [21]. Also, due to the acidic environment which favoured formation of amorphous sesquioxide bound-Zn in soil.…”

Zinc is considered as an important micronutrient for maize which is a promising emerging cash crop for the state of Assam, India. A field experiment was conducted at the experimental farm of Krishi Vigyan Kendra, Jorhat, Assam Agricultural University during 2018-19 and 2019-20 to study the dynamics of zinc fractions in soil in a maize-maize cropping sequence as affected by zinc fertilization. The experiment was laid down in a randomized block design (RBD) with twelve treatments combinations of basal and foliar application of zinc through zinc sulphate and zinc oxide nanoparticles (ZnO NPs). The results revealed that zinc fertilization significantlyinfluenced the studied zinc fractions in soil during both the years under investigation. The distribution of different zinc fractions in soils at harvest was found in the following order: water soluble plus exchangeable-Zn < complexed-Zn < crystalline sesquioxide bound-Zn < amorphous sesquioxide bound-Zn < residual-Zn. Among the zinc treatment combinations, soil application of Zn @ 3.75 kg ha-1 in combination with foliar application of 500 ppm ZnO NPs exhibited the highest concentration of water soluble plus exchangeable-Zn content (1.10 ppm) in soil. The highest concentration of complexed-Zn (2.95 ppm), amorphous sesquioxide-bound-Zn (4.11 mg kg-1), crystalline sesquioxide-bound-Zn (3.76 ppm), residual-Zn (125.65 ppm) and total-Zn (137.33 ppm) were recorded in the treatment receiving soil application of Zn @ 7.5 kg ha-1. Among the zinc fractions studied, the concentration and percent contribution of water soluble plus exchangeable-Zn to total-Zn was the lowest while residual-Zn fraction contributed the highest to the total soil zinc pool. Furthermore, path coefficient analysis revealed that the water soluble plus exchangeable-Zn had the highest contribution towards the plant available DTPA extractable-Zn in soil. Moreover, all the fractions of zinc were found to be significantly and positively correlated with each other indicating existence of dynamic equilibrium of zinc in soil.

“…This lower concentration of soluble zinc are in agreement with the findings of other authors (Kumar and Babel, 2011;Ramzan et al, 2014), who reported similar small amount, indicating that the soluble form contains less available contents in soils. Result shown negative significant correlation between soluble zinc with pH (-0.697*) while positive correlation but nonsignificant (Table, 4) shown with EC and available phosphorus, similar result found by Kandali et al, (2016) and Saxena et al, (2017). Singh and Umashankar, (2018) found inverse relationship of pH with water soluble zinc, and positive and significant relationships of exchangeable zinc with organic carbon and clay indicated that the available zinc increased with increase in organic matter and clay content.…”

Zinc adsorption was studied for ten selective representative soils according the difference amount of clay content, calcium carbonate and organic matter in Duhok governorate, Iraqi-Kurdistan region included (Kanimasi-1&2, Batofa, Zakho, Assih, Semeel, Khanke, Faydi, Zawita and Bamarny locations). Samples were air dried and sieved through a 2-mm sieve to study the physical and chemical characteristics of the soils, forms of zinc and it’s adsorption. Results showed the soluble, DTPA extractable zinc (available), CaCl2 extractable zinc (exchangeable) and total zinc ranged between (0.29 – 0.94), (0.88 – 1.64), (1.71 – 2.05), and (12.25 – 56.15) mg kg-1 respectively. Negative significant correlation found between soluble zinc with pH, also negative significant correlation found between DTPA extractable zinc with exchangeable potassium, bicarbonate and available phosphorus but positive significant correlation found between CaCl2 extractable zinc with pH, total–Zn negatively affected with pH and positively with HCO3 and sand. Results demonstrated that by increasing added zinc concentration to studied soil zinc will be adsorbed zinc adsorbed greatly at temperature 25°C and 48°C. In general total zinc adsorbed at 25C° in six concentrations was less than zinc adsorbed at 48C°. At temperatures 25°C and 48°C the high total amount of zinc adsorbed found in the soil of Zawita and Zakho respectively, but the lower total zinc adsorbed observed in soil of Batofa and Kani masi-2. The quantity of adsorption affected positively by presence of clay, calcium carbonate, active calcium carbonate and cation exchange capacity and negatively affected by the ion concentration of bicarbonate, calcium, potassium, organic matter and sand content.

“…Similar to WSEX -Zn, this fraction also contributed very less to total zinc and this could be due to medium organic matter content of the experimental soils. Similar finding were reported by Wijebandara et al,[32] and[33]. Based on result concluded that different fractions of soil Zn are in dynamic equilibrium with each other.…”

Field experiment was conducted at the research Farm of JNKVV, Jabalpur (M.P) during the Kharif season of 2018 with three main treatments as single year application, alternate and each year zinc addition and five levels of Zn (0, 2.5, 5, 7.5 and 10 kg ha-1 as sub treatments in a split plot design. Results revealed that alternate year Zn application increased seed yield by 1.48 t ha-1 over single year. The difference recorded in between alternate year and single year Zn application was 0.33 t ha-1. Treatment 5.0 kg Zn ha-1 had significantly increased seed yield by 1.43 t ha-1 over control. The difference recorded in between 5.0 kg Zn ha-1 and in control Zn application was 0.38 t ha-1. The each year Zn application and 10 kg Zn ha-1 gave the highest protein (40.30%) and oil content (20.17%) in seed. Results explained that the higher release of Zn pools were observed with the each year Zn application and 10 kg Zn ha-1. The order of prevalence of Water soluble and exchangeable-Zn< Complexed-Zn<Amorphous Sesquioxide < Crystalline Sesquioxide bound-Zn< Residual-Zn.
