The soil element is composed of natural soil, and the quality of this soil plays a vital role in the growth, development, and reproduction of the organisms that depend on it. To ensure optimal conditions, the process of preparing the soil is carefully managed, especially during the winter season when pest activity is minimal and microbial presence is lower.
When collecting the soil, it is first exposed to sunlight for disinfection and sterilization. This helps eliminate harmful bacteria and pests. After breaking up the soil and spreading it out, a sprayer is used to apply formalin diluted at 800 times, along with benzalkonium bromide, ensuring even coverage. Additionally, dichlorvos EC is sprayed at a 100-times dilution—100 grams per square meter—to further control pests. Once applied, the soil is covered tightly with plastic film to trap the fumigants and prevent air from escaping. The treatment lasts for one week, after which the area is ventilated for 1 to 2 weeks before proceeding.
After the fumigation process, 2 kilograms of weathered lime powder are added to every 100 kilograms of soil. This helps adjust the pH level and improve soil structure. The mixture is then sifted through a 6-mesh sieve to ensure uniformity and remove any large particles or impurities.
Maintaining the right moisture level is also crucial for the health of the soil. The ideal moisture content should be between 15% and 20%. When adding water during soil preparation, it's important to water the soil gradually and mix it thoroughly. A simple test is to form a small ball with your hand; if it holds its shape but crumbles when dropped, the moisture level is just right.
In summary, the best soil for cultivation should be loose, nutrient-rich, and consistently moist. These conditions promote healthy root development and support the overall vitality of the organisms living within it.
