Many thanks to P6 for giving our children a lot to think about with soil. Hopefully from the gardening club’s blog posts you will have seen that we have fertile land in Liss. Last week a group of children from Classes AS, KB & MG did some research into soils and came up with the following report.
What is soil?
Soil is the upper layer of the earth in which the plants grow. A black or dark brown material typically consisting of a mixture of organic remains.
Name the types of soil
These are the different types of soil:
Alluvial soil, Red soil, Laterite Black soil, Sandy soil, clayey soil, Loam, Peat and Humus.
Discuss ways soil is formed
The formation of soil happens over a very long period of time. It can take one thousand years or more. Soil is formed from the weathering of rocks and minerals e.g. gravel, sand, clay, chalk and water.
Mention components of soil
Worn down rock, dead and rotting material, air, water, chalk, clay, sand and gravel.
Write the importance of soil
Soil is a vital part of the natural environment. It is just as important as plants, animals, rocks, landforms, lochs and rivers. It influences the distribution of plant species and provides a habitat for a wide range of organisms. It controls the flow of water and chemical substances between the atmosphere and the earth, and acts as both a source and store for gases (like oxygen and carbon dioxide) in the atmosphere. Soils not only reflect natural processes but also record human activities both at present and in the past. They are therefore part of our cultural heritage. The modification of soils for agriculture and the burial of archaeological remains are good examples of this. Soil, together with the plant and animal life it supports, the rock on which it develops its position in the landscape and the climate it experiences, form an amazingly intricate natural system – more powerful and complex than any machine that man has created. Soil may look still and lifeless, but this impression couldn’t be further from the truth. It is constantly changing and developing through time. Soil is always responding to changes in environmental factors, along with the influences of man and land use. Some changes in the soil will be of short duration and reversible, others will be a permanent feature of soil development.
Discuss ways soil losses its fertility.
Soil losses its fertility when it doesn’t have enough water.
Define soil erosion
Too much water causes soil erosion.
Write the agents of soil erosion
Wind, water and ice are the agents of soil erosion.
Mention the causes of soil erosion
Soil erosion is mainly caused by rain, wind, flowing, overgrazing, soil exhaustion and deforestation.
Discuss the types of soil erosion
Wind erosion, gully erosion, mass movement, sheet erosion and rill erosion.
Identify some of the toxic materials in the soil
Weeds because they take all the water so the soil losses its fertility. Chemicals.
Discuss the effect of the harmful materials in the soil
Plants wouldn’t grow, animals would die and it would harm the animals.
What is soil conservation?
Measures to reduce soil erosion and replace nutrients into the soil.
Discuss ways of soil conservation.
Soil conservation is the best way to make sure that we have the land we need to live on. If you see your soil eroding, protect it with grass or plants. If you see something that’s making the soil sick, do everything you can to make the soil healthy again. If you live on a farm, make sure that the soil on your fields and pastures stays right where it is right now! This is a consequence of people’s deliberate efforts to use land wisely by means of proper farming techniques which prevent or minimize soil erosion in order to prevent sedimentation of rivers, lakes, irrigation, etc.
