Texture - The terms sand, silt, and clay refer to different sizes of the soil particles. Sand, being the larger size of particles, feels gritty. Silt, being moderate in size, has a smooth or floury texture. Clay, being the smaller size of particles, feels sticky.
Size - 0.002 mm
Soil particles vary greatly in size, and soil scientists classify soil particles into sand, silt, and clay. Starting with the finest, clay particles are smaller than 0.002 mm in diameter. Some clay particles are so small that ordinary microscopes do not show them. Silt particles are from 0.002 to 0.05 mm in diameter.
Color - Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide.
Sandy Soil:
Texture - Gritty
Sand, being the larger size of particles, feels gritty. Silt, being moderate in size, has a smooth or floury texture.
Size - 0.05 to 2.0 mm
Sand ranges from 0.05 to 2.0 mm. Particles larger than 2.0 mm are called gravel or stones. Most soils contain a mixture of sand, silt and clay in different proportions. The size of soil particles is important.
Color - Most beach sand color range from pale cream to golden to caramel, but in select places around the world, sands can be red, brown, pink, orange, gold, purple, green, and black.
Loam Soil:
Texture - Loam soils contain sand, silt and clay in such proportions that stickyness and non-adhesiveness are in balance - so the soils are mouldable but not sticky. Loams are the "friendliest" soils to cultivate.
Size - Loam (in geology and soil science) is soil composed mostly of sand (particle size > 63 micrometres (0.0025 in)), silt (particle size > 2 micrometres (7.9×10−5 in)), and a smaller amount of clay (particle size < 2 micrometres (7.9×10−5 in)).
Color - Most loam soils are a brown or black colour, making them ideal for gardens. It is often the most preferred type for plant growth and does well with just about any species.
