Tree plantation such as tea and rubber plantation cause low rates of soil erosion. Higher rates of soil erosion are caused by crops which are harvested annually like potatoes, most vegetables and tobacco. [11] Soil degradation in the dry zone leads to desertification. The loss of soil also is a big problem near watersheds, because a lot of ...
This has accelerated sea erosion, salt water intrusion and land degradation. Anthropogenic fires, particularly in savanna forests and grasslands, have led to the systematic degradation of forest habitats facilitating the spread of invasive species and consequently affecting natural regeneration of native species.
According to the U.N. FAO, 28.8% of Sri Lanka was forested in 2010 (about 1,86 million hectares). In 1995, it was 1.94 million hectares or 32.2% [11] of the land area that was classified as dense forests while the balance 0.47 million hectares or 7% the land area classified as open forests.

[34] [35] There is growing evidence that tillage erosion is a major soil erosion process in agricultural lands, surpassing water and wind erosion in many fields all around the world, especially on sloping and hilly lands [36] [37] [38] A signature spatial pattern of soil erosion shown in many water erosion handbooks and pamphlets, the eroded ...

The susceptibility of soil types to drought is a major concern in Akkaraipattu. The three main soil types in this area are: alluvial soil which has variable drainage and texture, reddish-brown soil, and Solonetz soil. The alluvial soil is generally found on flat flood plains.
Soil microbial communities experience shifts in the diversity and composition during dehydration and rehydration cycles. [5] Soil moisture affects carbon cycling a phenomenon known as Birch effect. [6] [7] Temperature variations in soil are influenced by factors such as seasonality, environmental conditions, vegetation, and soil composition.
