The ideal soil composition for crops grown in a light deprivation greenhouse should provide a balanced mix of nutrients, good drainage, and adequate moisture retention. A well-structured soil typically consists of a combination of loamy soil, which contains roughly 40% sand, 40% silt, and 20% clay. This composition allows for proper aeration and drainage while retaining essential moisture and nutrients.
Incorporating organic matter, such as compost or well-rotted manure, enriches the soil with nutrients and enhances its structure, promoting beneficial microbial activity. Including amendments like perlite or vermiculite can improve aeration and drainage, preventing root rot and other moisture-related issues.
