There are a wide variety of growing media and mixtures:
Clay> The clay or clay-textured soil types most delicate and sticky. Characteristics of clay are small pores (micro pores) more than large pores (macropores) so the ability to bind water is high enough. Small pores and fine capillary containing water or air, while the coarse pores filled with air or water gravity are easily lost. Because the micro pores are so small and narrow, causing water or air circulation becomes sluggish.
Clay or loam soil is nutrient poor that need to be combined with other ingredients that are rich in nutrients. The use of clay combined with other materials such as sand and humus suitable as seeding media, graft and media bonsai.

Due to the high content of organic matter in the compost is essential to improve soil conditions. Based on the known 2 the role of compost soil conditioner and soil ameliorator. Soil condotioner namely the role of compost in improving soil structure, especially the dry soil, while the soil ameliorator function in improving the soil cation exchange capability.
