The distributions of these materials affect post-fire processes of erosion, nutrient cycling, and vegetation regrowth.
This denuding of the landscape has led to desertification, soil erosion, nutrient depletion and epidemics of pests that further contribute to the country's food insecurity.
Soil erosion, nutrient depletion and other forms of land degradation reduce water productivity and affect water availability, quality, and storage.
Buffer zones in agroecosystems are maintained to prevent soil erosion, nutrient leaching and pesticide drift from arable fields.
Without herbicides, the best weed-killing tool is tilling, and that can lead to erosion, nutrient runoff and the disruption of the microbial community that organic farmers work so hard to foster.
In recent years, for example, U.S. farmers — working with agricultural experts — have dramatically improved practices in the corn and soybean belt, cutting down on erosion, nutrient loss, and groundwater pollution, even as yields have continued to increase.
The latter explained that chemicals from the leaves of Eucalyptus trees reduce the soil nutrients that are necessary for undergrowths, hence, enhancing soil degradation through erosion, nutrient and water depletion.
These soils are prone to degradation issues, and are susceptible to erosion, nutrient loss and salinity.
The Nigerien researchers argue that direct cash incentives are necessary to get producers to focus on the long-term issue of buffering production systems against such things as drought, wind erosion, nutrient mining and shrinking livestock forage sources.
