Abstract
The aim of this study is to study the effect of irrigation with groundwater on some soil properties in Minufia Governorate. 1) Determine some macro – and micronutrients in groundwater of Minufia Governorate. 2) Evaluate and determine the groundwater quality and its suitability as irrigation water resource. 3) Study the effect of groundwater on some soil morphological and chemical properties. as well as their contents of available macro – and micronutrient within different layers of soil profile. Fourteen soil profile were taken from different fourteen soil location in Minoufia Governorate, Egypt representing soils irrigated by groundwater plus one soil profile represents the soils irrigated by Nile water. The fourteen selected profile locations for this study were chosen depending on two basis. The first was the groundwater as a main water resource for irrigated and the second was the contour lines of Minufia Governorate. These soil profiles were taken at depth 150cm or level of water table. Layers of soil profiles were identified according to the vertical morphological variation. In the absence of morphological variation, the layers were taken of depth of 0 – 15, 15 – 30, 30 – 60, 60 – 90, 90 – 120, and 120 – 150cm. Samples of groundwater were taken and kept in glass bottles for analysis. The soil profile characteristics such as topography, slope elevation, natural, vegetation and or land use , drainage, water table, and soil surface feature were observed and registered. The soil profiles were morphologically described accounting to the guidelines of FAO (1990). from the morphological description of the studied soil profiles , the filed examination shows that the soils are deep (150 cm) except profiles 5, 9, 11 and 12 (El – Dabaiba, Tahway, Sobk El – Ahad, Bahnay). All the studied soils are well drained. Data of particle size distribution , showed that the content of sand, silt, and clay was varied widely from profile to another, and also from layer to another. They are arranged according to their amounts in all soil profiles. Data also showed that soil texture of the studied soil samples was varied widely from clayey to sandy within different layers of soil profiles. Data showed in all studied soil profiles that soil pH was decreased with the increase of soil depth and that trend may be attributed to the relative high organic matter in the surface layers compared with that found in the deeper ones . The soil pH in many soil sample was ranged from 7.5 – 8.0 . Total soluble salts ( as determined by EC) was varied from profile to another. Generally, the studied soil samples are characterized by low content of organic matter.
