The highest erosion in the 20-year period was recorded in the control treatment, following by the treatment that involved ploughing and sowing up and down the slope. Lower soil losses were recorded in no-tillage treatments and treatments with ploughing and sowing across the slope. No tillage ...
Changes in conjugated sterol content were related to the particular light conditions of each experiment. The results are discussed in terms of physiological cycles and the possible influence of hormones upon the control of sterol...
running water. The roots alsomake the soil porous, thereby allowing ground water infiltration and preventingfloods. Hence, plants are able to prevent soil erosion and natural calamities suchas floods and droughts. They also increase the fertility of soil and biodiversity. ...
Erosion control rolls are made of biodegradable materials that have been formed together into a long fiber sausage, about 8 inches in diameter, and staked to the ground along a slope. Over time the plant roots grow and hold the soil in place as the mat or roll breaks down into the soil...
Control soil erosion along slight slopes and flat areas by planting a leguminous ground-cover, such as clover. Break up the soil at the site using a rotary tiller. Scatter the seed across the tilled site. Cover the seeded area with a germination blanket to keep the seeds and tilled soil ...

How does climate affect soil formation? Why is it important to prevent soil pollution? How does overgrazing cause land degradation? What are the control measures of soil pollution? What agricultural activities cause soil pollution? How can overgrazing lead to soil erosion?
How can we control water runoff? Water Runoff: Water that is not absorbed into the soil is called runoff. This is because this water flows over the surface of the land and is then able to enter into waterways such as rivers and lakes. ...
Bioremediation (microbes) and phytoremediation (plants) can be used to convert the pollutants into harmless products. These are natural solutions that need to be supported by in-depth actions. Green agriculture: sustainable agriculture is essential as it is meant to control the impact on the ...
