 Shenzhen set of soil organic matter content of the soil copper content in soil radon detection Detection of universal testing Shenzhen set of universal Chen: 180-2871-93791. Sand sand-free organic, clean, pH neutral, suitable for cutting seedling, planting seedlings and direct planting cactus and more pulp plants.

When the pot, according to field 5 parts topsoil, sand l copies, organic fertilizer formulated o 2 copies of this good soil physical properties, both to retain water and nutrients there are drainage luck, help supply root development and water. 3. M rot humus soil generally consists of ten leaves, leaves and other decaying made contains a lot of organic matter, sulfur loose fertile, good ventilation and drainage.
