“…Using the Cate-Nelson method, by Zare et al (2009) A. H. Khoshgoftarmansh et al Zn by DTPA and EDTA for corn in non-saline soils in central Iran, were 1.5 and 1.17 mg kg −1 , respectively. In earlier studies critical levels of about 0.6, has been reported for corn (Srivastava and Gupta, 1996;Pal et al, 1989). Takkar et al (1989) reported that the critical level of soil Zn for maize ranged from 0.38 to 1.40 mg kg −1 .…”

“…On alkaline soils, 0.6 mg-kg −1 DTPA-extractable Zn is considered to be critical for corn (Bansal et al, 1990a(Bansal et al, , 1990b. The critical concentration of soil Zn for corn was 0.6 mg kg −1 for some soils of India (Pal et al, 1989;Srivastava and Gupta, 1996). Singh (1986) reported the DTPA-extractable soil Zn and plant tissue Zn critical level for corn as 0.54 and 15.4 mg kg −1 , respectively.…”

2 A greenhouse experiment with 11 soil series and two zinc (Zn) rates (0 and 15 mg Zn kg −1 as zinc sulfate) was performed to determine critical deficiency level of Zn for corn (Zea mays L.) on calcareous salt-affected soils in central Iran. In addition, the most important soil properties affecting Zn phytoavailability were determined. Critical Zn deficiency levels were determined using the Cate-Nelson and Mitscherlich procedures. In most soils, application of Zn increased the dry matter yield, and Zn concentration and content in the shoot and root of corn. A positive correlation was observed between the soil electrical conductivity (EC) with Zn concentration in shoots, roots and whole plant while shoot Zn content was negatively correlated with buffer capacity of Zn in soil. Critical deficiency levels of Zn in soil for corn based on the Cate-Nelson and Mitscherlich method were 1.35 and 1.23 mg kg −1 for diethylenetriaminepentaacetic acid (DTPA)-extracted soil Zn, respectively.

“…Inappropriately managed irrigated soils can also become saline due to the accumulation of salts. In Madhya Pradesh, India, critical EC values of 35 mS cm -1 , where DTPA-Zn is below 0.6 mg Zn kg -1 and 55 mS cm -1 where the DTPA-Zn is above 1.0 mg Zn kg -1 and/or the soil has a loam or sandy clay loam texture, are used in a model for predicting the risk of Zn deficiency in maize (Pal et al 1989).…”

Zinc deficiency is the most ubiquitous micronutrient deficiency problem in world crops. Zinc is essential for both plants and animals because it is a structural constituent and regulatory co-factor in enzymes and proteins involved in many biochemical pathways. Millions of hectares of cropland are affected by Zn deficiency and approximately one-third of the human population suffers from an inadequate intake of Zn. The main soil factors affecting the availability of Zn to plants are low total Zn contents, high pH, high calcite and organic matter contents and high concentrations of Na, Ca, Mg, bicarbonate and phosphate in the soil solution or in labile forms. Maize is the most susceptible cereal crop, but wheat grown on calcareous soils and lowland rice on flooded soils are also highly prone to Zn deficiency. Zinc fertilizers are used in the prevention of Zn deficiency and in the biofortification of cereal grains.

“…The deficiency of Zn has been frequently referred to maize, which is a crop very sensitive to it (Murphy and Walsh, 1983;Pal et al, 1989). In general this deficiency is not caused by the total concentrations in the soil of this element but by very low concentrations in the soil solution (Adriano, 1986).…”

To test the effectiveness of coated and uncoated Zn fertilizers prepared with commercial zinc ethylenediaminetetraacetate (Zn−EDTA) and zinc lignosulfonate (Zn−LS), maize (Zea mays L.) was greenhouse cultivated in calcareous soils dosed with 5, 10, and 15 mg·kg-1 Zn. Crop yield increased from 25 g per pot in control to 42 and 39 g per pot when 15 mg·kg-1 Zn was added by applying Zn−EDTA-3 and Zn−LS-0 fertilizers, respectively. Although big amounts of Zn were taken by plants, concentrations in soil increased from 43 to 55 and 57 mg·kg-1 when 15 mg·kg-1 Zn as Zn−EDTA-3 and Zn−LS-3 was applied. Rosin coating improved the performance of Zn−EDTA fertilizers but scarcely did in fertilizers with Zn−LS. A large part of Zn applied remained in the soil in forms easily available to plants (water soluble plus exchangeable, organic complexed, and DTPA-extractable Zn), more so when the source of Zn was zinc lignosulfonate. Positive, significant correlations were obtained between the variables, yield, Zn concentration, and Zn uptake by the plant with respect to the available Zn and the first two sequentially extracted fractions (water soluble plus exchangeable and organically complexed). The Zn uptake by maize could be fairly accurately predicted from the sequential fractioning in the soil after harvesting using an equation obtained through multiple regression analysis.
