Which of the following materials is considered inexpensive compared to peat moss?

• A. Bark
• B. Coir
• C. Sawdust
• D. Vermiculite

Answer: (A)

Bark is considered inexpensive compared to peat moss because it is a readily available byproduct of the timber industry. Bark has properties that make it useful for horticultural purposes, such as being a good source of aeration and serving as a slow-release nutrient source when decomposed. Its abundance and lower production costs contribute to its affordability in comparison to peat moss, which requires more extensive harvesting and processing, making it relatively more expensive. Both coir and sawdust have varying costs depending on local availability and processing, while vermiculite is typically more expensive and valued for its lightweight and moisture retention properties. Understanding the cost-effectiveness of these materials is important for greenhouse management, as it directly impacts budget and resource allocation for growing media.
