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 do you call the study of soils in agriculture?

They include:

  • Olericulture: the production of vegetables.
  • Pomology, also called fruticulture: the production of fruits and nuts.
  • Viticulture: the production of grapes (largely intended for winemaking).
  • Floriculture: the production of flowering and ornamental plants.
  • Turf management: the production and maintenance of turf grass for sports, leisure and amenity use.

Important benefits of soil include natural protector of seeds and plants; dispersal and germination of seeds within soil ecosystem; physical support system for plants; retaining and delivery of nutrients to crops.


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.


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 ).


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.


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 the National Cooperative Soil Survey?

Since 1899 the partnership in soil surveys has been called the National Cooperative Soil Survey (NCSS). When the Soil Conservation Service was formed in 1935 their soil surveys were primarily for privately owned farms rather than the county soil surveys of the National Soil Survey group.


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

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).


What is the organic component of soil?

Organic component of soil. Further reading. Soil is the loose surface material that covers most land. It consists of inorganic particles and organic matter. Soil provides the structural support to plants used in agriculture and is also their source of water and nutrients. Soils vary greatly in their chemical and physical properties.


What gives soil its texture?

The combination of mineral fractions (gravel, sand, silt and clay particles) and organic matter fraction give soil its texture. Texture grades depend upon the amount of clay, sand, silt and organic matter present. The solid part of the soil is made up of particles such as organic matter, silt, sand and clay which form aggregates.


How does organic matter contribute to soil?

Soil organic matter contributes to stable soil aggregates by binding soil particles together. Plants living in soil continually add organic matter in the form of roots and debris. Decomposition of this organic matter by microbial activity releases nutrients for the growth of other plants.


What is the inorganic fraction of soil?

It is the inorganic fraction of soils which determines soil physical properties such as texture.


What determines the physical properties of soil?

The relative proportion of sand, silt and clay particles determines the physical properties of soil including the texture. The surface area of a given amount of soil increases significantly as the particle size decreases. Consequently, the soil textural class also gives an indication of soil chemical properties.


What is the solid part of soil made of?

The solid part of the soil is made up of particles such as organic matter, silt, sand and clay which form aggregates. Aggregates are held together by clay particles and organic matter. Organic matter is one of the major cementing agents for soil aggregates.


How does soil structure affect plant growth?

Soil structure influences plant growth by affecting the movement of water, air and nutrients to plants. Sandy soils have little or no structure but are often free draining. With higher clay contents the soil structural strength increases, but its drainage ability often decreases.

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.


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.
