What is the long term process of losing soil fertility and plant life?
desertification: Conversion and degradation of land which previously supported to plant growth, in arid or semi-arid regions, to desert land. This often occurs as a result of drought, deforestation, or other human induced land use changes.
What is the long term process of soil loss?
Soil erosion is a gradual process of movement and transport of the upper layer of soil (topsoil) by different agents – particularly water, wind, and mass movement – causing its deterioration in the long term.
What is it called when soil loses its fertility?
Soil depletion occurs when the components which contribute to fertility are removed and not replaced, and the conditions which support soil’s fertility are not maintained. This leads to poor crop yields. In agriculture, depletion can be due to excessively intense cultivation and inadequate soil management.
What causes the fertility of the soil to diminish?
Erosion, compaction, nutrient imbalance, pollution, acidification, water logging, loss of soil biodiversity and increasing salinity have been affecting soil across the globe, reducing its ability to support plant life and so grow crops.
What does the term land degradation refer to?
Land degradation is the reduction or loss of the biological or economic productivity and complexity of rain—fed cropland, irrigated cropland, or range, pasture, forest or woodlands resulting from natural processes, land uses or other human activities and habitation patterns such as land contamination, soil erosion and …
Why is loss of soil fertility occurring as an effect of Green Revolution?
Why is loss of soil fertility occurring as an effect of the Green Revolution? Answer: During the Green Revolution, due to the extra crops produced which utilised the soil nutrients fully, no nutrients were left for the next crop.
What are the factors that have affected the soil fertility and degraded it?
Rainfall, surface runoff, floods, wind erosion, tillage, and mass movements result in the loss of fertile top spoil thereby declining soil quality.
What are two ways that soil loses its fertility?
Soil erosion. – Top soil is lost by the agent of erosion e.g.
How do soils lose their fertility?
Human interactions in the environment can affect soil. The value of soil is reduced when soil loses its fertility or when topsoil is lost due to erosion. Loss of Fertility: Soil can be damaged when it loses its fertility. This can happen through loss of nutrients. It can also happen by the loss of moisture.
What decreases soil fertility?
Growing eucalyptus decreases the soil fertility. It degrades soils and release carbon. That too, planting eucalyptus as monoculture tree plantations are very harmful to soil. It decreases the soil pH and increases soil acidity such that Aluminium ions play a dominant role.
What are some ways to improve soil fertility?
A lesser-known way to improve soil fertility is to plant different crops in the same field in order to prevent soil erosion and control the spread of soil-borne plant disease. Doing this with legumes will have the benefit of adding nitrate to the soil. Try to use deep rooted vegetables, which will improve soil fertility naturally.
