“…The acetic acid in Mehlich 3 aided the extraction of P from soil by promoting the dissolution of phosphates bound with Ca, whereas, the presence of fluoride facilitated the extraction of phosphates associated with Fe and Al (Shahandeh et al, 2017;Wuenscher et al, 2015). Mehlich 3 also extracted higher amounts of K and S from soils than those with ammonium acetate (Mehlich, 1984) and CaCl 2 (Rao and Sharma, 1997) (Seth et al, 2017). Soil properties are known to influence extraction of essential plant nutrients from soil by the chemical extractants.…”

“…Forty surface (0-0.2 m) soil samples, varying widely in their physicochemical properties, were collected from typical rice growing areas (20 each from Inceptisols and Alfisols) of West Bengal, India. Details of location and classification of the soils were given in our earlier publication (Seth et al, 2017). A portion of the soils was air dried under shade, ground, passed through 2.0 mm nylon sieve and stored for chemical analysis and the remaining part was used for the pot experiment.…”

“…Wendt (1995) found that that Mehlich 3 offered comparable predictions of soil fertility, like other standard soil extractants, for a range of macronutrients and micronutrients. Again, use of a multi-nutrient extractant like Mehlich 3 is advantageous for routine laboratory analysis of available plant nutrients, because it offers the assessment of nutrient status in soil in cost effective and time saving manner by means of simultaneous extraction of a large number of essential nutrients in a single step (Seth et al, 2017;Pradhan et al, 2015).…”

We evaluated the critical limits of P, K, S, B and Zn in Inceptisols and Alfisols for nutrition of rice (Oryza sativa L.) using Mehlich 3 as an extractant. Three levels, each of P (0, 14 and 23 mg kg -1 soil), K (0, 23 and 36 mg kg -1 soil), S (0, 4.5 and 9.0 mg kg -1 soil), B (0, 0.5 and 1.0 mg kg -1 soil) and Zn (0, 2.3 and 4.5 mg kg -1 soil) were applied separately to 20 Alfisols and Inceptisols each for growing rice in greenhouse. Biomass yield, concentration and uptake of those nutrients by rice were significantly influenced (P ≤ 0.01) by the soil and rate of each of the nutrients (P, K, S, B and Zn), but not by their interactions in both the soil orders. The amount of these five nutrients as extracted from soils by Mehlich 3, alike conventional extractants, showed significant positive correlations (P≤ 0.01) with biomass yield, nutrients concentration and their uptake by rice plant, which indicated suitability of Mehlich 3 in predicting plant available nutrients in soil. The critical levels of Mehlich 3 extractable P, K, S, B and Zn for rice in Inceptisols were 14.7, 51.2, 22.9, 0.65 and 1.27 mg kg -1 ; while in Alfisols those values were 8.2, 117.3, 21.9, 0.40 and 2.15 mg kg -1 , respectively.

Background: Chemical methods allowing a single soil extraction followed by multi‐elemental simultaneous measurement by ICP‐OES are increasingly used to predict plant uptake; however, calibration results against crop response are scarce and contradictory.Aims: Our aims were to evaluate the efficacy of five extractants to predict nutrient uptake by a greenhouse wheat crop, as well as the influence of soil properties on nutrient concentrations in soil extracts and wheat plants.Methods: Unlike other calibration studies, we monitored the pre‐seeding to post‐harvesting changes in soil available Ca, K, Mg, Cu, Fe, Mn, Zn, and Al. We extracted 14 acidic soils (C content: 47–114 g kg−1) with two traditional (AA: ammonium acetate; DTPA: diethylenetriamine‐pentaacetic acid) and three multi‐element extractants (AB‐DTPA: ammonium bicarbonate‐DTPA; Mehlich‐3; AA‐DTPA: ammonium acetate‐DTPA).Results: Relationships between bioavailable and chemically extractable elements were strong for K (R2 = 0.776 to R2 = 0.882; p < 0.001) and Zn (R2 = 0.663 to R2 = 0.721; p < 0.001), especially for AB‐DTPA and AA‐DTPA. Multiple regressions including also soil properties can predict wheat‐Ca (Feoxihydroxides, clay and CaAB‐DTPA; R2 = 0.656; p < 0.001) and wheat‐Cu [Aloxihydroxides and either CuAB‐DTPA (R2 = 0.515; p < 0.01) or CuAA‐DTPA (R2 = 0.472; p < 0.01)]. Pre‐seeding to post‐harvesting changes in KAA‐DTPA and KAB‐DTPA were strongly related with K uptake by wheat (R2 = 0.927 and R2 = 0.949, respectively; p < 0.001); similarly, for wheat‐Zn the best relationships were with ZnMehlich‐3 and ZnAA‐DTPA (R2 = 0.654 and R2 = 0.757, respectively; p < 0.001).Conclusion: Consequently, chemical extractants alone can adequately predict K and Zn bio‐availability, and combined with some soil properties can predict wheat uptake of Ca and Cu, but not that of other nutrients.

Effects of micronutrients on Khao Dawk Mali 105 rice in Thai paddy soils and assessment of their availability indices

Background: Micronutrient deficiency is currently the major cause of declining productivity in rice-growing countries, including Thailand. A pot experiment was conducted to determine limiting micronutrients (Fe, Mn, Zn, and Cu) for Khao Dawk Mali 105 (KDML 105) rice, in four soil types. Soil micronutrient speciation and in-soil extracts were examined to identify the species controlling the availability to the plant and the efficiency of soil extract to assess the availability indices of multi-micronutrients for KDML 105 rice.Results: Micronutrients in the studied soils were in the order Fe > Mn > Cu > Zn, mostly in stable forms accounting for 96.8%-99.7%, 81.3%-96.5%, 95.6%-97.6%, and 83.3%-98.0%, respectively, and in available fractions of only 0.32%-3.2%, 3.55%-18.66%, 2.44%-4.42%, and 2.03%-16.74% respectively. The omitted Fe had the greatest effect on limiting the rice grain yield with a significant reduction of 24.12%-46.46%, whereas the omitted Zn had the least effect. To assess the availability for KDML 105 rice, DTPA pH 7.3 was the most suitable multipurpose extractant for Fe, Mn, and Cu, while HCl was superior to other extractants for Zn. All oxide fractions were responsible for supplying available Fe, Mn, and Cu, while Zn was generated from the organic and exchangeable fractions. Conclusions:The yield of KDML 105 rice can be increased by adding each of these micronutrients but yield magnitude was different depending upon their deficient levels in soils. The oxide-bonded micronutrients were the species controlling its availability and DTPA pH 7.3 was suggested as the multipurpose extractant for micronutrient availability indices indicators.
