Fe, Mn, Zn and Cu Extractability and availability in Egyptian soils
für 53.10€ kaufen ··· 9783848404735 ··· 1036118347 ··· Ninety eight surface soil sample were collected from different locations throughout the A.R.E. to assess the status of cationic micronutrients (Fe, Mn, Zn and Cu) in different soils of Egypt. 1) The tested methods of extraction that could be more promising for assessing soil Fe availability could be ordered descendingly, according to their r values, with nutrients uptake by barley seedlings as follows: Mehlich III AAAc-EDTA DTPA CAT AB-DTPA. 2) All the tested procedures, (except BDW) showed significant correlations with Mn plant uptake at a very high significant levels, they could be arranged according to their r values, descending in the order: Mehlich III CAT AAAc EDTA ABDTPA DTPA Coca-Cola. 3) The methods of soil Zn extraction that are significantly correlated with Zn plant uptake could be arranged according to their r coefficient descendingly in the order: CAT W.H AAAc-EDTA. 4) The tested methods of micronutrients extraction, yielded always significant correlation between the extractable Cu values and Cu plant uptake. The observed relation significancy decreased in the order: W.H.
