What is an important aspect of soil health for nursery production?

Organic matter content is a crucial aspect of soil health for nursery production because it significantly influences the physical, chemical, and biological properties of the soil. High organic matter improves soil structure, enhances nutrient and water retention, and supports a diverse community of soil organisms. These benefits contribute to healthier plant growth and resilience against pests and diseases.

In nursery production, having a rich organic matter content allows for better aeration and rooting, promoting strong plant establishment. It also boosts the soil's ability to sequester carbon, improve moisture retention, and provide slow-release nutrients—an essential factor for sustaining healthy plants over time. In contrast, while synthetic fertilizers can provide quick nutrient boosts, they do not improve soil structure or long-term soil health in the way organic matter does. The presence of invasive species can negatively affect soil health by disrupting native ecosystems and nutrient cycling, while a soil drainage layer is important for specific structural aspects but does not encompass the overall health benefits provided by organic matter. Thus, focusing on increasing and maintaining organic matter in nursery soils is a fundamental practice for ensuring robust and sustainable plant production.
