Different between loamy soil, Sandy soil and clayey soil in table
Answers
Clay particles are smallest, followed by silt, then sand. Particle sizes affect a number of things: how quickly water or other constituents move through the medium; tendency to attach to various substrates (e.g. channel bed and subsequent aggradation); etc. However, these are just the physical properties. Knowing more about the chemistry and interactions with biota require you to know the chemical make-up of the soil medium. Instead of going down that rabbit hole, I can give more qualitative answers to your question:
Sandy soil has good drainage, but can be bereft of nutrients. Because the soil particles are large, the medium is very porous, allowing chemical constituents to pass through before plants can absorb them. Sandy soils can dry out quickly for the same reason and prone to erosion, particularly by wind erosion.
Loamy soils are typically good for agricultural because they have the right balance between nutrient-retention and drainage. Moreover, loam is usually described as having humus (or organic carbon). The humus in loams provide the structure for nutrient retention as well as providing nutrients as they degrade into simpler compounds.
Clay soils are diverse since they are defined by their chemical constituent. Due to their water and nutrient retention properties, they’re technically fertile, but their microscopic structure are tight enough that water has difficulty flowing/draining. Hence, clays are known to be poor soils as plant roots may not be strong enough to penetrate the clay medium, which is dense/strong enough to resist human tools as well.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
→ SANDY SOIL
- Sandy soil contains large coarse particles which we call sand .
- This soil is mainly found in the places with warm climate such as deserts and marshy areas.
→ LOAMY SOIL
- Loamy soil contains large and fine particles of sand silt and clay.
- Silt is a type of soil formed due to the deposition in river beds.
