In nutrient management, soil aeration influences the availability of many nutrients. Particularly, soil air is needed by many of the microorganisms that release plant nutrients to the soil. An appropriate balance between soil air and soil water must be maintained since soil air is displaced by soil water.
In addition to sustaining all life on Earth, soil water provides a pool of dissolved nutrients that are readily available for plant uptake. Therefore, it is important to maintain proper levels of soil moisture. Soil water is the medium from which all plant nutrients are assimilated by plants.
Air pollution can significantly hurt the quality of soil and water resources. When we pollute our air, we are also polluting the precipitation that falls into water bodies and soils.
Answer: yes air is present in water. Explanation: air is present in water in diffused state, this air is required to breathing of aqautic animals like fishes.
Soil moisture is a key variable in controlling the exchange of water and heat energy between the land surface and the atmosphere through evaporation and plant transpiration. As a result, soil moisture plays an important role in the development of weather patterns and the production of precipitation.
Sustain Life and GrowthOxygen present in the air is one of the main life-sustaining gas. All living things breathe in and breathe out the air in the form of oxygen and carbon dioxide. Nitrogen and Carbon dioxide are vital for plants and their growth.
Water and air are polluted. If resources are carelessly managed, many will be used up. Through conservation, people can reduce waste and manage natural resources wisely. The population of human beings has grown enormously in the past two centuries.
When water is added to soil, it can replace the oxygen that is naturally in the soil, and make the soil darker. This means wetter soil will have less oxygen compared with drier soil. When enough water is added, soil can become saturated and the water will start to form a layer on top of it.
- Fuelwood. For the rural population, wood is an important source of energy for cooking and heating.
- Fodder. Fodder from the forest forms an important source for cattle and other grazing animals in the hilly and the arid regions and during a drought.
- Wind breaks and shelter belts.
- Soil erosion check.
- Soil improvement.
Trees are vital. As the biggest plants on the planet, they give us oxygen, store carbon, stabilise the soil and give life to the world's wildlife. They also provide us with the materials for tools and shelter.
Characteristics of the tropical forest
- high animal and vegetal biodiversity.
- evergreen trees.
- dark and sparse undergrowth interspersed with clearings.
- scanty litter (organic matter settling on the ground)
- presence of "strangler" creepers (e.g. Ficus spp.)
Ten Ways to Preserve Our Forests
- Protect More Ancient Forests.
- Use Ecoforestry in All Secondary Forests.
- Support Canada's National Forest Strategy.
- Ban the Import of Illegally Logged Timber.
- Use Less Paper and Wood.
- Eat Less Beef.
- Invest in Rainforest Communities.
- Support the Activists.
1 If forests disappear, the amount of carbon dioxide in air will increase, resulting in the increase of earth's temperature. 2 In the absence of trees and plants, the animals will not get food and shelter. 3 In the absence of trees, the soil will not hold water, which will cause floods.
Answer: Shrinkage of forest owe reasons: 1) lack of land availability for settlement or cultivation leading to Deforestation, Encroachment etc. 2) commercial use of forest based products like rubber, timber, fuel, paper etc.
The most common pressures causing deforestation and severe forest degradation are agriculture, unsustainable forest management, mining, infrastructure projects and increased fire incidence and intensity.
Wildlife plays an important role in balancing the environment . Wildlife provides a stability to different processes of the nature . Wildlife and nature have been largely associated with humans for emotional and social reasons . We are also a part of wildlife to make ecological balance on earth.
We need Nature for food, water, to regulate the air that we breathe, to control water levels, to keep us sane, even for all the raw materials that underpin our lives. Nature isn't important to Man, it's essential. We are a species too - and we may be endangered.
The importance of forests cannot be underestimated. We depend on forests for our survival, from the air we breathe to the wood we use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion and mitigate climate change.
There is a difference between forest area and forest cover. Geographical area recorded as forests in government records is forest area. All lands, more than one hectare in area with a tree canopy density of more than 10 per cent is called forest cover. Such lands may not be statutorily notified as forest area.
Fresh trees should be planted and in this way the trees that are cut should be replaced. Planting of trees should be a constant progress. Besides, trees that are planted must be of the right type. They should be such that can prevent soil erosion, check floods, and air pollution.
10 Solutions for Natural Resource Depletion

- Use Sustainable Agriculture Practices.
- Reduce Food Waste.
Tropical rainforests are often called the “lungs of the planet” because they generally draw in carbon dioxide and breathe out oxygen. But the amount of carbon dioxide they absorb, or produce, varies hugely with year-to-year variations in the climate.
Forests are renewable resources and play a major role in enhancing the quality of the environment. They modify the local climate and control soil erosion. They regulate the flow of streams and support a variety of industries like the rubber industry. They provide humus to the soil and shelter to wildlife.
Forest cover in general refers to the relative (in percent) or sure (in square kilometers/square miles) land area that is covered by forests.
Plants are really important for the planet and for all living things. Plants absorb carbon dioxide and release oxygen from their leaves, which humans and other animals need to breathe. Living things need plants to live - they eat them and live in them. Plants help to clean water too.
