what is mean by conservation of resources? why is its importance for man
Answers
Explanation:
Resource Conservation
Resource conservation means that those resources on which sustainability depends are conserved and even enhanced by agronomic management. Soil organic matter is a good example of an ecosystem resource that is easily reduced without effective management. Soil organic matter declines rapidly in almost all cropping systems following initial cultivation – typically to 40–60% of original values within a few decades. However, soil organic matter is a valuable resource, providing habitat and energy for soil organisms, a soil structure favorable for plant growth and water retention, and a chemical structure favorable for nutrient retention (Robertson and Grandy, 2006).
The loss of soil organic matter is often associated with a need for greater external inputs. Cropping practices that conserve or enhance soil organic matter buildup will invariably enhance the environmental and often the economic sustainability of cropping systems. Crops grown in high-organic matter soils have a better water and nutrient environment
Explanation:
Conservation means usage, improvement, protection of human and natural resources in a wise manner. ... ... Hence, these resources should be conserved to maintain ecological balance and save them for future generations. The proper management of a resource to prevent its destruction or exploitation is called conservation.
