Agriculture Notes On – Problems Of Soil – For W.B.C.S. Examination.

কৃষিবিদ্যা নোট – মাটির সমস্যা – WBCS পরীক্ষা।

Soil is the earth’s fragile skin that anchors all life on Earth. It is comprised of countless species that create a dynamic and complex ecosystem and is among the most precious resources to humans. Increased demand for agriculture commodities generates incentives to convert forests and grasslands to farm fields and pastures. The transition to agriculture from natural vegetation often cannot hold onto the soil and many of these plants, such as coffee, cotton, palm oil, soybean and wheat, can actually increase soil erosion beyond the soil’s ability to maintain itself.Continue Reading Agriculture Notes On – Problems Of Soil – For W.B.C.S. Examination.

Half of the topsoil on the planet has been lost in the last 150 years. In addition to erosion, soil quality is affected by other aspects of agriculture. These impacts include compaction, loss of soil structure, nutrient degradation, and soil salinity. These are very real and at times severe issues.

The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding. Sustainable land use can help to reduce the impacts of agriculture and livestock, preventing soil degradation and erosion and the loss of valuable land to desertification.

The health of soil is a primary concern to farmers and the global community whose livelihoods depend on well managed agriculture that starts with the dirt beneath our feet. While there are many challenges to maintaining healthy soil, there are also solutions and a dedicated group of people, including WWF, who work to innovate and maintain the fragile skin from which biodiversity springs.

Soil is a natural finite resource base which sustains life on earth. It
is a three phase dynamic system that performs many functions and
ecosystem services and highly heterogeneous. Soil biota is the biological
universe which helps the soil in carrying out its functions. Often soil
health is considered independently without referring to interlinked soil
functions and also based on soil test for few parameters. Physical
condition of soil and biological fertility are overlooked in soil health
management which needs revisiting of soil users. Recognising the
importance of soil health in all dimensions, 2015 has been declared as the
International Year of Soils by the 68th UN General Assembly. Food and
Agriculture organisation of the United Nations has formed Global soil
partnership with various countries to promote healthy soils for a healthy
life and world without hunger. India, the second most populous country
in the world faces severe problems in agriculture. It is estimated that out
of the 328.8 m ha of the total geographical area in India, 173.65 m ha are
degraded, producing less than 20% of its potential yield (Govt. of India,
1990).
