Sand is highly permeable to water; water flows through it easily. Clay is relatively waterproof, and water flows through it with great difficulty. This is because of the relative size of sand particles as compared to clay particles. Clay particles are extremely tiny, and therefore have much smaller gaps between them when they are packed together.
sandy soil will allow more water because it is more porous than the clayey soil.
Loose or sandy soils allow water to percolate(pass) through them faster
because sandy soil can absorb water only at a limit
Water can easily move through sandy soils, wheras clay-rich soil is much harder for water to penetrate, so sandy soils are drier.
it is best because its texture is intermediate between sandy and clayey soli. sandy is easy to cutlivate but yet too porous to retain water and therefore most soil nutrients, since they are mostly in liquid form. while clayey has the highest water retention capacity but it gets easily waterlogged and therefore hard to cultivate. loamy has both advantageous properties of sandy and clayey and lacks any of their disadvantages. it is easy to cultivate, has good retention and is porous allowing its easily aeration and living of micro organisms which break down the soil even further and when they die, enrich the soil with their organic remains (humus).

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.
Clayey soil hold the most water of all, as sand and chalk. Loamy soil holds water but not as much as clayey.
Clay has the highest water holding capacity. This is because clay is made up very small tightly packed particles that do not allow water to percolate through.
put more bottles
Water that does not percolate (move down through the soil) either is retained above the impermeable layer or becomes surface runoff.
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.
this is because wheat requires a lot of water which is present in clayey or loamy soil.
