There are four main types of soil with each one offering its own benefits and weaknesses in the health of your garden. The particle size enrichment ratios for the EPSD measurements (i.e., aggregate soil particles) show an enrichment in the three smallest particle size classes (< 63 μm), a depletion in the largest size class (> 125 μm) and the 63–125 μm fraction had values close to 1 . Gravel is anything larger than that; silt and mud are finer. Two types of mudstone are shale and argillite, which is shale that has undergone very low-grade metamorphism. scale for particle size because the ratio of particle sizes from the largest to the smallest in a soil can be greater than 104 (Budhu 2000). Sand particles are the largest and clay particles the smallest. Clay soils are made up of small plate-like particles and thus have the smallest pore spaces (spaces between particles). Furthermore, large sand particles can be described as coarse, intermediate as medium, and the smaller as fine. Type C soil is the least stable type of soil. Clay particles are very small – less than 0.002 mm. Most soils are a combination of the three. a. clay, silt, sand b. silt, sand, clay c. silt, clay, sand d. sand, silt, clay.
