What is the role of compost in greenhouse crop production?

The role of compost in greenhouse crop production is fundamentally about enriching the soil and improving its structure. Compost consists of decomposed organic materials, which enhance the nutrient content of the soil, providing essential elements required for plant growth. By incorporating compost into the growing medium, it helps increase soil fertility, which is vital for healthy plant development as it contains key nutrients that are readily available to plants.

Furthermore, compost contributes to better soil structure by improving aeration and drainage while retaining moisture. Healthy soil structure promotes root development as roots can more easily spread out into the soil, accessing water and nutrients. This leads to stronger, more resilient plants that can better withstand environmental stressors and diseases.

While compost may assist indirectly in suppressing some pests due to its improved soil health, it is not primarily designed to act as a pesticide. Similarly, it does not provide shade like physical structures or shade cloths would, nor is it primarily intended as a mulch alternative, even though it may fulfill some mulching functions. Its primary benefits are centered around enriching the soil and enhancing its quality.
