Soil fertility in systems under arid and semi-arid conditions . permanent soil cover and for signiﬁcant crop residues because of water shortages.
Soil fertility in systems under arid and semi-arid conditions, hereafter referred to as dry. areas or drylands, is constrained by environmental extremes of hot and cold temperatures, as well as by low water availability. The contribution of different soil and land parameters to olive yield is not well understood.

Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Earth's body of soil, called the pedosphere, has four important functions: as a medium for plant growth. as a means of water storage, supply and purification. as a modifier of Earth's atmosphere. as a habitat for organisms. All of these functions, in their turn, modify the soil.

The Developments in Soil Science series has been designed to provide a comprehensive source of theoretical and practical reference books for scientists working in the broad field of soil science. Topics include Synchrotron-based Techniques in Soils and Sediments, Geomorphometry, Soil Quality and Conservation, Soil Micromorpohlogy and Soil Chemistry.
Soil physics and hydrology is the study of soil physical, hydraulic and thermal properties and processes in soil. These processes are applied to many aspects of environmental and agricultural sciences, particularly those related to natural and managed ecosystems. Soil physics and hydrology deals with the dynamics of physical soil components and their phases (solids, liquids, and gases).
