For a sandy soil with soil grains spherical in shape and uniform in size, what is the theoretical void ratio?
Appu’s father plans on opening an Anthurium flower farm. He read that Anthurium plants require soils with good water absorption capacity along with good aeration. He has three choices: Clayey soil, Sandy Loam soil and coco peat (an artificial soil made from coconut husks). He took 50 g of each soil and determined the volume of water it absorbed. He also determined the soil particle size using a microscope and tabulated the results.
