Abstract

Many countries are facing environment change. This study aims to study the distribution of salinity and some nutrient (i.e. N, P, Fe, Mn, Zn and Cu) under recently environment change "climate factors, soil factors and human factors" in soils adjacent to North Delta, Idku region, Behra Governorate, Egypt between year 1986 and year 2011, whereas about 900 000 ha suffer from salinization problems, 6 % of Northern Delta region are salt-affected. Fourteen profiles (thirty nine samples), these representative profiles were transects vertical to Idko Lake. The study area is located between 31o 10'and 310 40' N, and longitudes 30o 25' and 310 20' E. The Idko Lake found on distance 1km the Mediterranean Sea. The obtained results could be summarized as follows: Weight means to Electric conductivity (EC) in year 1986 were different the values in profiles. EC values of the studies soil were decrease with increase of soil depths. The highest values of EC were found in most profiles. The EC was between 1.30 to 51.70 dSm-1, in comparison with year 2011 in all profiles were between 0.70 to 3.10 dSm-1 very slightly saline to non saline. In year 2011 available N in all profiles was medium whereas values were between 52.88 to 74.32 mg kg-1. In comparison, in year 1986 available N was very lowest whereas values were between 1.20 to 10.6 mg kg-1. In year 2011 was lowest available P in all profiles. In comparison with, year 1986 was between high and medium, whereas values were between 3.20 to 44.80 mg kg-1. Available Fe in year 2011 increase in mostly profiles, whereas range was between 2.00 to 32.6 mg kg-1. In comparison with, year 1986 was range was between 2.00 to 14.2 mg kg-1. Available Mn in year 2011 increases in profiles, whereas range was between 2.10 to 5.50 mg kg-1. In comparison with, year 1986 was range between 8.00 to 30.0 mg kg-1. Data in year 2011 show that range available Zn was 0.45 to 5.60 mg kg-1. In comparison with, year 1986 found profiles between 1.00 to 10.6 mg kg-1. Available Cu is given in year 2011 show that highest value was all profiles. Available Cu of the studied profiles was range between 1.00 to 19.6 mg kg-1. In comparison with, year 1986 all profiles were high, whereas range was between 3.20 to 11.8 mg kg-1
