Salinization
  • Salinization is the increase of salt concentration in soil and is, in most cases, caused by dissolved salts in the water supply. Hence, statement 1 is correct.
  • This supply of water can be caused by flooding of the land by seawater, seepage of seawater or brackish groundwater through the soil from below.
  • Due to climate change, sea levels are rising, which further accelerates the process of salinization.
  • The addition of excessive unwanted material in the soil alters the level of minerals and nutrients present in it.
  • The increasing human population has led to an increase in the amount of waste generated.
  • This waste when left untreated on soil increases its salinity.
  • Soil salinity is also increased due to excessive use of fertilizers and improper farming techniques.

Salinization

Salinization refers to the increase in salt concentration in an environmental medium, notably soil. This process can have detrimental effects on soil fertility and plant growth.

Causes of Salinization

- Salinization can be caused by natural processes such as the weathering of rocks and minerals, as well as by human activities like irrigation with salty water or the excessive use of chemical fertilizers.
- It can also occur due to poor drainage systems, which lead to the accumulation of salts in the soil over time.

Effects of Salinization

- High salt concentrations in the soil can hinder plant growth by reducing water uptake and nutrient absorption.
- Salinization can also lead to the degradation of soil structure, making it more difficult for plants to establish healthy root systems.
- In severe cases, salinization can result in the loss of arable land and decreased crop yields, impacting food security.

Preventing and Managing Salinization

- Implementing proper irrigation practices, such as using low-salinity water and ensuring adequate drainage, can help prevent salinization.
- Soil testing and monitoring salt levels regularly can also aid in the early detection and management of salinization.
- Reclaiming saline soils through practices like leaching with freshwater or adding soil amendments can help reduce salt concentrations and restore soil fertility.

In conclusion, salinization is a significant environmental issue that can have far-reaching consequences on agriculture and ecosystems. By understanding its causes and effects, as well as implementing appropriate management strategies, we can work towards mitigating the negative impacts of salinization on soil health and plant productivity.

Similar Humanities/Arts Doubts

Read the case below and answer the questions that follow:The evidence for hereditary influences on intelligence comes mainly from studies on twins and adopted children. The intelligence of identical twins reared together correlates almost 0.90. Twins separated early in childhood also show considerable similarity in their intellectual, personality and behavioural characteristics. The intelligence of identical twins reared in different environments correlated 0.72, those of fraternal twins reared together correlated almost 0.60, and those of brothers and sisters reared together correlated about 0.50, while siblings reared apart correlated about 0.25. Another line of evidence comes from the studies of adopted children, which shows that children’s intelligence is more similar to their biological rather than adoptive parents. With respect to the role of the environment, studies have reported that as children grow in age, their intelligence level tends to move closer to that of their adoptive parents. Children from disadvantaged homes adopted into families with higher socioeconomic status exhibit a large increase in their intelligence scores. There is evidence that environmental deprivation lowers intelligence while rich nutrition, good family background, and quality schooling increases intelligence. There is a general consensus among psychologists that intelligence is a product of complex interaction of heredity (natur e) and environment (nurture). Heredity can best be viewed as something that sets a range within which an individual’s development is actually shaped by the support and opportunities of the environment.Choose the correct option:Q. Children’s intelligence is more closely related to their _____________ parents.

Direction: Read the case study given below and answer the questions that follow:Available water resources are degrading rapidly. The major rivers of the country generally retain better water quality in less densely populated upper stretches in hilly areas. In plains, river water is used intensively for irrigation, drinking, domestic and industrial purposes. The drains carrying agricultural (fertilizers and insecticides), domestic (solid and liquid wastes), and industrial effluents join the rivers. The concentration of pollutants in rivers, especially remains very high during the summer season when flow of water is low. The Central Pollution Control Board (CPCB) in collaboration with State Pollution Control Boards has been monitoring water quality of national aquatic resources at 507 stations. The data obtained from these stations show that organic and bacterial contamination continues to be the main source of pollution in rivers. The Yamuna river is the most polluted river in the country between Delhi and Etawah. Other severely polluted rivers are: the Sabarmati at Ahmedabad, the Gomti at Lucknow, the Kali, the Adyar, the Cooum (entire stretches), the Vaigai at Madurai and the Music of Hyderabad and the Ganga at Kanpur and Varanasi.Ground water pollution has occurred due to high concentrations of heavy/toxic metals, fluoride and nitrates at different parts of the country.What is the main role of CPCB?
