Substrate soil, also known as growing soil or medium soil, is artificially prepared soil used for plant growth. It is usually composed of a variety of different materials to meet the plants' needs for nutrition, air, water, and pH. The methods for preparing substrate soil are diverse and mainly depend on the type of plant, growth stage, and environmental conditions. Here are some common methods for preparing substrate soil:
1. Organic-Inorganic Mixture Method: This method combines the advantages of organic and inorganic materials. Organic materials such as leaf mold, compost, and peat can provide the plants with the necessary nutrients and organic matter, while inorganic materials like perlite, vermiculite, and sand help improve soil drainage and aeration. This mixed substrate soil is suitable for most plants, especially those requiring good drainage and ample nutrition.
2. Pure Organic Substrate Method: This method uses only organic materials, such as well-rotted compost, leaf mold, peat moss, and coconut coir. This type of substrate soil is suitable for plants sensitive to chemical fertilizers, such as certain indoor plants and vegetables. Pure organic substrate soil typically has good water retention and nutrient capacity but may require more frequent fertilization.
3. Soilless Culture Method: This method does not use soil but instead uses a matrix composed entirely of inorganic materials, such as hydroponics, aeroponics, and rock wool culture. This method allows for more precise control of the nutrients and environmental conditions required for plant growth, suitable for high-tech agriculture and indoor plant cultivation.
4. Light Substrate Method: Lightweight substrates like perlite, vermiculite, and Styrofoam beads can reduce the weight of the matrix, improving aeration and drainage. This type of substrate soil is suitable for rooftop gardens and hanging plant cultivation and is also used for container cultivation that needs to reduce weight.
5. High Fertility Substrate Method: To enhance the fertility of the substrate soil, organic fertilizers like bone meal, blood meal, and fish meal can be added during the preparation process. These organic materials release essential nutrients for plants during decomposition, such as nitrogen, phosphorus, and potassium.
6. pH Adjustment Method: According to the plant's needs for soil acidity or alkalinity, the pH value of the substrate soil can be adjusted by adding lime or ferrous sulfate. For example, plants that prefer acidic soil like blueberries and azaleas can have their substrate pH value lowered by adding ferrous sulfate.
7. Water Retention Substrate Method: To improve the water retention of the substrate soil, water retention agents like sodium polyacrylate or vermiculite can be added. These materials can absorb and slowly release water, reducing the frequency of watering and are suitable for dry regions or plant enthusiasts who often forget to water.
8. Bioactive Substrate Method: Adding bioagents like EM (Effective Microorganisms) to the substrate soil can enhance soil biological activity and promote plant root growth and health. This method is suitable for organic agriculture and improving soil quality.
9. Specific Plant-Dedicated Substrate Method: Customized substrate soil can be prepared for specific plant needs. For example, cacti and succulents require substrate with excellent drainage, primarily consisting of sand and perlite; while orchids need a substrate with both good aeration and water retention, such as bark and moss.
10. Environmental Protection Substrate Method: Using recycled materials like old newspapers, sawdust, and coconut shells can reduce waste while providing a growth matrix for plants. This method is both environmentally friendly and cost-effective, suitable for large-scale plant cultivation.
Each method for preparing substrate soil has its specific advantages and limitations, and the choice of method depends on the plant's needs, cultivation environment, and personal preferences. When preparing substrate soil, the following points should also be considered: proportion, disinfection, testing, and updating. By preparing substrate soil properly, plants can be provided with a suitable growth environment, promoting healthy growth and increasing yield.
