Soil erosion: An agricultural production challenge Integrated Crop ...
Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. Soil deterioration and low water quality due to erosion and surface runoff have become severe problems worldwide. The problem may become so severe that the land can no longer be cultivated and must be abandoned.

The Causes and Effects of Soil Erosion, and How to Prevent It
2020年2月7日 One study estimated global economic losses from soil erosion to be around $8 billion, due to reduced soil fertility, decreased crop yields and increased water usage. In Java, Indonesia, soil erosion is responsible for a 2% loss in total agricultural GDP , taking into account the losses farmers face directly and the losses others face downstream.

Effect of soil erosion depth on crop yield based on topsoil
2021年9月7日 A reliable correlation between crop yields and soil erosion is critical for the assessment of soil loss tolerance and loss of future food production in eroded farmlands. However, the heterogeneity between experiments in terms of soil properties, crop types, and farming management makes it difficult to compare and extrapolate results from different
