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 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 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.
