Sandy soils are generally less fertile than clay soils because they do not hold water as well as clay soils. Clay soils are usually fertile and hold more nutrients than sandy soils.

Why are sandy soils generally less fertile than clayey soil?
Sandy soils are generally less fertile than clay soils because they do not hold water as well as clay soils. Clay soils are usually fertile and hold more nutrients than sandy soils.
What factors account for different capillarity in soils?
Texture, for one. Coarser soils (sandy) have much less capillary action than finer soils (clayey).
Why are sandy soils generally less fertile than clayey soils?
All things being equal (which, of course, they never are), sandy soil will feel drier than clay soil because sand provides better drainage, mainly because it far more porous than clay. Clay is dense, less porous than sand, and acts somewhat like a sponge. actually sand is less porous then clay but other then that the above answer is fine. clay has a better ability to retain water like a sponge.
Why sandy soils are drier than the clayey soil?
Sandy soils have larger particles with more space between them, allowing water to drain quickly and making them drier. In contrast, clayey soils have smaller particles which hold onto water more effectively, resulting in higher moisture content and less drainage, making them wetter.
Is soil more fertile in mounains than in plains?
Generally, soils in mountains tend to be less fertile than in plains due to erosion, steep slopes, and colder temperatures which limit organic matter accumulation. However, certain mountain regions with volcanic activity or mineral-rich soils may have fertile soils. Overall, soil fertility can vary greatly based on specific conditions and geological history of the area.
What are the different types of soils found in Haiti?
The main types of soils found in Haiti include volcanic soils, alluvial soils, and limestone soils. Volcanic soils are fertile and found mainly in the northern part of the country. Alluvial soils are deposited by rivers and are found in valleys and low-lying areas. Limestone soils are found in the southern part of Haiti and tend to be less fertile.
How do clay soils differ from sandy soils?
Clay soils have smaller particles and hold more water and nutrients, making them more fertile but prone to compaction. Sandy soils have larger particles, drain quickly, and don't retain much water or nutrients, making them less fertile but easier to work with.
Is the soil in the desert fertile?
Generally, soils in deserts tend to be less fertile due to low organic matter content, lack of vegetation, and high temperatures that break down nutrients. However, there are some desert areas with fertile soils, such as oases or regions with periodic water sources that support more plant growth and organic matter accumulation.
Laterite soils contain high amount of?
Iron oxide
Is clayey or sandy soil more susceptible to erosion?
Sandy soil is generally more susceptible to erosion than clayey soil. This is because sandy soil has larger particles and less cohesion between them, making it easier for water to wash away the soil particles. Clayey soil, with smaller particles that stick together more, is more resistant to erosion.
What four regional categories of California's soils?
The four regional categories of California's soils are coastal, foothill valley, desert, and mountain soils. Coastal soils are found near the ocean and are characterized by high organic content. Foothill valley soils are found in the inland valleys and support a variety of agricultural crops. Desert soils are found in the arid regions of the state and have low organic matter. Mountain soils are found in the higher elevations and are often rocky and less fertile.
Why crops grown in sandy soil need frequent irrigation than the crop grown in clayey soilcrops grown in sandy soil need frequent irrigation than the crop grown in clayey soil?
Because the pore space (the space between soil particles) in sandy soil is so much larger. In sandy soils, the water is drawn by gravity downward and away from the roots quite easily, but in clay soils, the pore space is so much smaller that capillary action holds the water much more tightly. This is the same reason that clay soils flood more easily and take longer to dry out.
