“…This suggested that the organic acids or compounds produced during the decomposition of organic matter react with iron and form soluble organo-iron complexes, which prevent the iron from fixation by soil constituents. Similar observations were noticed by Katyal and Sharma (1991).…”

“…The above correlation suggests that zinc availability decreased with increase in soil pH and CaCO 3 content probably due to formation of insoluble zinc hydroxide and zinc carbonate at higher pH and the ability of CaCO 3 to adsorb zinc and this form of zinc does not come into the solution easily. Similar findings were reported by Katyal and Sharma (1991), Prasad (1991), Nayak et al, (2000) and Chidanandappa et al, (2008). These results are in accordance with the results of Sharma and Lal (1992).…”

This may be due to the medium to high organic carbon status of these soils as evidenced by a positive correlation observed between available iron and organic carbon status of these soils.…”

“…Also, in 57 Indian soils (eight orders, including Oxisols and Ultisols), the total Zn concentration in soils showed highly significant correlation with clay content, but no correlation with the pH and the other soil properties. [29] The multiple linear correlation analysis among sequential extracted fractions of Zn and soil characters confirmed the finding of correlation analysis. In all studied soils, various Zn fractions significantly and positively correlated with each other because of the dynamic equilibrium among the different pools of Zn in soils.…”

Knowledge of zinc (Zn) distribution among various fractions will help to predict the potential of the soil to supply sufficient Zn for crop production. The present study was done to investigate Zn fractions, Zn availability factor (AF) and their relationship with soil properties of Zn-deficient tropical paddy soils. The samples of two soil orders (six soil series) were sequentially extracted with chemical extractants in two different growth stages of rice (maximum tillering and flowering stages). The proportion of Zn fractions extracted at the maximum tillering stage followed the order, water soluble plus exchangeable (WE) < crystalline sesquioxide (Cry) < manganese oxide (MN) < organically bound (Org) < amorphous sesquioxide (Amor) < residual Zn (Res), whereas the order at the flowering stage was as follows: WE < Mn < Cry < Org < Amor < Res. Cation exchange capacity (CEC), clay content and organic carbon (OC) were the most important factors controlling the distribution of Zn in soils. The AF was low in Tok Young (1.79%), high in Telemong (17%) and medium in the rest of soil series (around 8%). A stepwise multiple linear regression and principal component analyses showed that OC, clay content and CEC were the main variables that explained the predictability of Zn fractions. The result of the length of submerging showed that the WE, Org and Cry concentrations decreased, while Amor, MN, and the sum of all Zn fractions increased with increase in the flooding period. The extractability and solidphase fractionation of Zn in two different times of soil sampling showed the importance of timing of Zn fertilizer application and flooding or pre-flooding in Zn availability.

“…Sharma et al (2004) found that total content of Fe, Cu, Zn and Mn increased with an increase in clay and silt. Several other researchers reported also that the total trace elements increased with increasing silt and clay content (Katyal and Vlek, 1985;Katyal and Sharma, 1991;Sharma et al, 1992). Kishk et al (1980) reported that there was very close correlation between soil texture and both total and DTPA-extractable Fe.…”

Meanwhile, in soil samples collected from corn farms, available Fe, Mn, Zn, Cu, and Mo ranged from 1. 70-8.35, 0.74-10.5, 0.82-3.12, 0.32-3.91, undetectable-0.04 mg kg -1 , respectively. The shoot contents of Se, Mo, Zn and Cu were low and deficient in alfalfa and corn plants. However, it was observed that the shoot contents of Fe and Mn were sufficient. Based on correlation coefficients and multivariate analyses including principal component (PCA) and cluster analyses (CA), soil properties of clay content, CEC and OM altered trace elements availability and consequently can modify the response of forage plant in study area.
