Zinc for crop production | UMN Extension
网页2018年8月15日 · Zinc sulfate (35% zinc) is usually used to supply the needed amount of zinc when dry fertilizer materials are used. This material can be either broadcast and incorporated before planting, or used in a starter fertilizer. It blends well with other dry fertilizer materials. Approximately 3 lb of the zinc sulfate material will supply 1 lb zinc per ...
网页• Inorganic sources include: zinc sulphate, zinc oxide, zinc carbonate, zinc nitrate, and zinc chloride. Zinc sulphate is the most commonly used zinc fertilizer worldwide and is available in both crystalline monohydrate and heptahydrate forms.
网页These zinc fertilizers differ in total zinc, water-soluble zinc concentration, price and composition (Table 1). Fertilizers with zinc sulfate, especially in its heptahy-drate form (e.g., ZnSO 4.7H2O), are the most common-ly applied zinc fertilizers due to the higher solubility and relative low cost of zinc sulfate.
Zinc Fertilizer Sources - Crop Quest
网页Sulfates are the most commonly applied inorganic zinc fertilizer. Zinc sulfate is a granular product that may be banded or broadcast. There are two forms of zinc sulfate: Zinc monohydrate with 36% zinc. More commonly used due to availability, higher zinc content per pound and lower water content resulting in lower transportation costs.
Zinc Fertilizers - an overview | ScienceDirect Topics
网页Zinc sulfate (ZnSO 4 ·xH 2 O) is produced by reacting ZnO with sulfuric acid (H 2 SO 4). It is the most commonly used Zn fertilizer and it is available in the monohydrate and heptahydrate forms. Zinc sulfate is highly water soluble (96%) and dissolves quickly in …
网页Zinc sulphate (ZnSO4) is the most widely applied inorganic source of zinc to soils or leaves due to its high solubility, low cost, and availability in the market. Zinc can also be applied to soils in forms of zinc oxide and Zn-oxysulphate.
Foliar zinc fertilization improves yield, biofortification and nutrient ...
网页2023年3月10日 · Applying Zn fertilizer (either as a foliar spray or into soil) increased grain Zn concentration relative to that of the control treatment; maximum biofortification was achieved with foliar application (37.9 mg kg −1), where the Zn concentration in grains was 29% higher than the control.

网页The commonly used Zn fertilizers are soluble zinc sulfate (23−36% Zn), soluble zinc chloride (48−50% Zn), and insoluble zinc oxide (60−80% Zn). Developed with inputs from V Balasubramanian, RJ Buresh and M Bell
Zinc fertilizers for Citrus production: assessing nutrient supply via ...
网页2023年3月11日 · Regarding the plant, Zn-EDTA via fertigation increased leaf nutrient levels only after the third year of fertilization, whereas Zn-nitrate via foliar spray increased leaf levels in the short term, up to 120 mg kg −1. To a lesser extent, Zn-EDTA or sulfate also increased leaf Zn compared to the control.
