When you have a look at the tire of the car, you will notice that the numbers are written in the following pattern: P215/50R17. What is the Meaning of the First Letter? The first alphabet on the tire can be P, LT, ST or T. Sometimes there is the absence of the first alphabet. The first alphabet denotes:
Clay is one of the three principal types of soil, the other two being sand and loam. A certain amount of clay is a desirable constituent of soil, since it binds other kinds of particles together and makes the whole retentive of water. Excessively clayey soils, however, are exceedingly difficult to cultivate.
Clay soils tend to stay cooler and also retain water. There are several types of clay soils, including a lime rich clay called Calcareous Clay which is said to be even cooler. These soils are famous for producing some of the boldest red and white wines in the world.andy soils are well-drained and retain heat. In warm climate regions, sandy soils make wines that are âsofterâ with less color, lighter acidity and tannin. If youâve ever had a wine from Swartland, South Africa and seen how pale the wines can be, this is part of the reason why.
