Abstract

Identifying the situation of some micronutrients and study the effect of some physical and chemical properties of soils on nutrients status is reveal their importance on agricultural productivity. Clay content, soil pH, salinity, soil organic matter and calcium carbonate content are the main factors which influence nutrients availability in the soil. Some extractable micronutrients contents i.e., Fe, Mn, Zn, Cu as well as B and their relation to some factors are studied in the soils of El-seala area at El-Bahareya region, Egypt. To achieve this target, thirty two representative soil profiles in the study area were investigated. The obtained results are summarized as follows: DTPA extractable amount of Fe, Mn, Zn, Cu and B ranged between1.3–22.9, 2.1-17.9, 0.1-7, 0.1-20.3 and 0.15-7.15 mg kg-1, respectively. Some values of micronutrients are much greater than the marginal levels reported in the literature i.e. about 30.6 % for Fe, 100 % for Mn, 50 % for Zn, 38 % for Cu and 11.2 % for B. In general the soil profiles which have light texture contain low amounts of micronutrients, while on the other hand high amounts of these elements are shown in the heavy texture. About 7.5 % of soil samples have toxic limits of extractable B for soils under investigation. About 20.05 % of soil samples have sufficient limits of available Fe. About 21.85 % of soil samples contain sufficient amounts of available Mn. About 18.45 % of soil samples have adequate of extractable Zn. The critical values of the studied soil profiles reached to 43.75 % for Cu. The statistical analysis i.e., the simple correlation coefficients between DTPA-extractable micronutrients and some soil variables are determined.
