study of local environment of some wild plants in Badan area, Ibb governorate, Yemen

ABSTRACT

In the year 2002 [from January to June], some wild plants were studied in Badan [Al-Hafah, Alkhlal Alasfal and De-almalk], Ibb Governorate, where 56 plant species belonging to 52 genera and 34 families were collected. Also, physical and chemical properties of the soil of these plants on different depths were determined and compared with others. Physical properties include soil moisture content[water content], hygroscopic water, available water, soil texture [mechanical analysis by sieves]. and water holding capacity, porosity and capillary water. From the chemical properties, pH value, electrical conductivity, calcium carbonate, total soluble salts, chlorides, carbonates and bicarbonates were examined
