Which is the best soil for agriculture?

The “classic” best soils for farming are drained wetlands. These high organic matter soils are rich in nutrients. Also, former wetlands will likely have better supply of soil moisture than the comparable uplands. There are high environmental costs from draining and farming wetlands, but that’s a different topic.


What is the meaning of soil science in agriculture?

Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.

Why are soil scientists important?

A soil scientist is a person who is qualified to evaluate and interpret soils and soil-related data for the purpose of understanding soil resources as they contribute to not only agricultural production, but as they affect environmental quality and as they are managed for protection of human health and the environment.

What is soil & What is the importance of soil for plants?

Soil is an important element essential for the survival of living organisms. The soil dissolves the minerals and nutrients in the water and transports it to different parts of the plants. These are essential for the growth and development of the plant. The fertile soil helps in the growth and development of the plants.

Students will understand that soil provides anchorage for roots, holds water and nutrients, is home to micro and macroorganisms, filters water, stores carbon, and is a foundation for humans to build and produce food.

Why is soil important to the Earth?

The soil is the best natural resource available to us. It is vital for our survival on the earth. The topsoil which is desirable for the growth of plants is eroded because of human activities like making of homes, roads, buildings and city expansions.

What is the role of soil in the growth of plants?

Soil fertility. Fertile soil aids the growth of plants. As a result, these plants produce important needs to humans like clothing, food, medicine and furniture. Even other insects and animals get food by pasturing on plants.

What is the soil loaded with?

The soil is loaded with fulvic acid, and this means all of the alfalfa, barley, oat and wheat grass greens are packed with minerals, enzymes, and vitamins. Unluckily we belong to the generation where we have accustomed to neglect balanced soil contact by foot. Most of us are unaware of the touch, feel and properties of the soil.

What is the mineral that soil provides?

The soil is a source of minerals. Minerals and mines existing in the soil are a source of multiple metals like bauxite, iron, zinc etc. various metal elements are fused with soil and thus extracted from soil by technical methods.

What is soil in agriculture?

For us (from the agricultural point of view) it is an unconsolidated mineral or organic material that is on the surface of the earth in which we grow plants.

What determines the texture of soil?

All the above-mentioned properties determine the texture of soil. Every soil is a mixture of three main components: sand, clay and silt. A very useful tool to verify a given soil texture is the soil textural triangle that you can see on the right. It shows you what kind of soil you are working on by taking into consideration the soil’s components.

What type of soil is the most fertile?

It shows you what kind of soil you are working on by taking into consideration the soil’s components. Loam is the most fertile type of soil and has a mixture of these components. For example, a more sandy soil will have a high hydraulic conductivity and a low water holding capacity.

Why does clay flood?

Sometimes when there is a compacted layer of clay underground it can lead to flooding after heavy storms. Water does not have anywhere to go in such a short time, so its level goes higher and eventually floods our plants. Moreover a higher percentage of clay and silt in the soil will increase the cation exchange capacity .

How to improve sandy soil?

There are different solutions to enhance sandy soil performance. One of them is to add more of the organic matter content. The organic matter is a mixture of living and recently dead materials such as previous crop residue, livestock waste or simple organic matter, such as leaves. The organic matter does two things for our soil.

What happens if you add too much organic matter to soil?

If there is too much of it, in addition to supplying plants with too much nutrients it will start oxidizing, which provides an additional supply of nutrients .

We all know that soil is a key element of agriculture. Without it we wouldn´t be able to grow plants, which are used as food for both humans and animals. In this blog post I would like to focus a little bit more on the technical side of soil and explain some of its chemical and physical properties. There are different definitions …

What is soil science?

Soil science is concerned with processes taking place from the nanometer to the kilometer scale and beyond, and from the near-instantaneous to geologic timescales. It is common to speak of scales in a colloquial manner – ‘pore-scale,’ ‘lab-scale,’ ‘overnight’ – and the mental images that these terms invoke can be useful, although they are not quantitative. Less useful are terms such as ‘microscale,’ which naturally carry widely different meanings between, and even within, different disciplines. Because soil science is inherently interdisciplinary, such words will have different meanings even to different soil scientists and should be avoided. If quantitative terms are needed, then using the size itself is best: ‘meter-scale,’ for example.

Why are soils important to ecosystems?

Soils provide and support many interpretive functions in ecosystems. All soil functions are environmental because soils are integral parts of terrestrial ecosystems. Important ones include biomass transformations, partitioning of water, regulation of fluxes, providing habitats, and other uses.

What is pedology in science?

Pedology is a subdiscipline of Soil Science; it is an interpretive venture into the existence of surficial earthy materials that we call as soils. It is a probabilistic world; all measurements contain uncertainty. Measurements do not include value judgments. Numbers to not care and soils do not care, people do.

What is the National Cooperative Soil Survey?

What is the need for a historic understanding of soil science?

Given the expansion of the soil science discipline, there is a need for a historic understanding how we define soil, and how the definition has evolved over time. There is also a need to revisit what the definition of soil means and what such a definition should include.

What type of soil is found in northern Siberia?

Early investigators of polar soils showed all land in northern Siberia as being mantled with Tundra soil. The tundra is described as developed on a treeless plain of the north where conditions are swampy and the land is underlain by permanently frozen ground (permafrost).

When was soil science established?

Soil science as a scientific discipline was established in the 1800s. The discipline has developed a strong jargon which was needed to define and name the soil material and its many features. Semantics, or the science of meanings, has influenced the development of some subdisciplines in soil science (Wilde, 1953 ).
