Using Soil as a Growing Media

ICL recognises soil as an integral part of growing medium in horticulture. Soil is not merely a substrate but a complex ecosystem that is essential for plant health and horticultural productivity. Here, we detail the benefits of soil and offer guidance on optimising its health for growing success.

What is the value of Soil?

Soil is composed of organic matter, minerals, gases, and a vibrant community of organisms. It provides several vital functions that are critical for plant growth:

• Nutrient Provision: Soil is a natural reservoir of essential nutrients, including macronutrients like nitrogen, phosphorus, and potassium, which are crucial for plant health.
• Moisture Regulation: The physical structure of soil helps in maintaining adequate moisture levels by balancing water retention and drainage, which is crucial for plant health.
• Biodiversity Support: The biodiversity within soil, including microorganisms such as bacteria and fungi, as well as larger organisms like earthworms, plays a key role in organic matter decomposition, nitrogen fixation, and overall soil fertility.
• Sustainability Enhancement: Soil supports sustainable horticultural methods, including plant rotation and organic planting, which help preserve soil integrity, prevent erosion, and reduce the carbon footprint.

How do I optimise Soil Health?

Optimising soil health is fundamental to enhancing horticultural productivity. Effective strategies include:

• Soil Testing: Periodic soil testing is essential to understand its nutrient status, pH level, and structure. This information guides targeted interventions to maintain or improve soil health.
• Soil Amendments: Depending on soil needs, organic or inorganic amendments can be applied to adjust pH levels, improve soil structure, and replenish nutrient deficiencies.
• Sustainable Management Practices: Implementing practices such as reduced tillage, use of cover crops, and strategic crop rotation can significantly improve soil structure, enhance organic matter, and prevent soil erosion.
• Appropriate Fertilisation: Controlled-release fertilisers can be more efficiently utilised by plants, reducing runoff and environmental degradation.
