Soil structure exerts important influences on the edaphic conditions and the environment. It
is often expressed as the degree of stability of aggregates. Aggregation results from the …

Irrigation has long played a key role in feeding the expanding world population and is
expected to play a still greater role in the future. As supplies of good-quality irrigation water …

Since the publication of the third edition of the Handbook of Plant and Crop Stress,
continuous discoveries in the fields of plant and crop environmental stresses and their …

Sodicity‐induced soil degradation is a major environmental constraint with severe negative
impacts on agricultural productivity and sustainability in arid and semiarid regions. As an …

Any management practice that results in greater carbon (C) return to the soil, increases
stabilization of soil C, or reduces C losses may lead to soil organic carbon (SOC) storage in …

There is a strong link between desertification of the drylands and emission of CO 2 from soil
and vegetation to the atmosphere. Thus, there is a strong need to revisit the desertification …

Reclamation of salt-affected soil has been identified by the FAO as being critical to meet the
needs to increase agricultural productivity. This paper reviews commonly used reclamation …

Sodic soils are characterized by the occurrence of excess sodium (Na+) to levels that can
adversely affect soil structure and disturb availability of some nutrients to plants. Such …

Currently at least 20 per cent of the world's irrigated land is salt‐affected. However,
projections of global population growth, and of an increased demand for food and fibre …

This chapter summarizes general information on salt-affected soils and factors influencing
their formation and reclamation, and discusses salinity and sodicity as plant/crop stress …
