The number one worst country is Central African Republic (2.0). Almost all soils that have been cropped without fertilizer for 100 years or more will have become deficient in one or more of the plant nutrients. Solving the Agricultural Water Problem.

Levels of flood damage are rising and the risk of casualties is following. Soil salinization (salinisation) is the increase of salt concentration in soil and is, in most cases, caused by dissolved salts in the water supply. Common to: sandy soils Amendments to add: compost If your crop beds drain and dry out too quickly, they can benefit from the addition of compost, which will add both nutrients and water-retention capacity. The soil pH is a measure of the acidity or exchangeable hydrogen ions (H+) in soil. However, the effects of living for many years on or near soils with above-average levels of contamination can be harder to determine. Often this light-colored soil is used to grow tobacco, coffee, tea and fruit. About 5.8×10 6 km 2 of soils around the world are sodic (Bui et al., 1998) and have the potential for transient salinity.
