Understanding Organic Soil: A Beginner's Guide to Sustainable Growing (Malta & Southern Europe)

Organic Soil Layers

Introduction

Organic soil is the cornerstone of sustainable gardening, promoting healthier plants, enhanced biodiversity, and environmental preservation. This easy-to-follow guide provides essential information and practical tips specifically tailored to warmer, arid climates such as Malta and Southern Europe, helping growers maximize soil health and productivity.

What is Organic Soil?

Organic soil refers to soil rich in natural, decomposed organic matter, beneficial microbes, and essential nutrients derived from plant and animal residues. Unlike conventional soil, organic soil avoids synthetic fertilizers and pesticides, fostering a natural growing environment.

Key Components of Organic Soil

1. Organic Matter

• Compost: Essential for improving moisture retention in arid conditions.

• Humus: Helps in maintaining soil moisture and reducing evaporation.

2. Minerals

• Rock Dust: Natural minerals like basalt and granite dust replenish essential nutrients, particularly important in nutrient-poor Mediterranean soils.

3. Beneficial Microorganisms

• Bacteria and Fungi: Essential microbes that enhance drought resistance in plants.

• Mycorrhizae: Improve root efficiency, critical for water and nutrient uptake in dry climates.

4. Soil Amendments

• Biochar: Improves water retention significantly, beneficial for drought-prone areas.

• Pumice vs. Perlite: Environmentally friendly alternatives that provide soil aeration while helping to retain moisture.

Benefits of Organic Soil in Arid Climates

1. Improved Soil Moisture Retention: Reduces watering frequency.

2. Enhanced Nutrient Availability: Gradual release ideal for nutrient-poor soils.

3. Increased Plant Resilience: Supports plants in extreme heat and drought conditions.

4. Pest and Disease Resistance: Stronger, healthier plants less susceptible to pests.

5. Environmental Sustainability: Essential in combating soil degradation and erosion common in arid regions.

Practical Tips for Organic Gardening in Malta & Southern Europe

Preparing Organic Soil Mixes

• Incorporate abundant compost and biochar for maximum moisture retention.

• Use locally sourced organic amendments like seaweed and animal manures.

• In Mediterranean climates, you can collect the organic fallings from a carob tree or other local trees and use this improve the organic matter content while providing natural beneficial organisms to mitigate against any pests.

• The options that produce the most organic matter are mostly Carob, fig and olive tree's. However you can use whatever is available, just try avoid pine tree needles, as these would need to be composted first and or mulched.

Application of Amendments

• Frequent small additions of organic matter help maintain moisture and nutrient levels.

• We provide three unique blends tailored to the Mediterranean soil and climatic conditions.

• We recommend using them as toppers, by sprinkling or dusting small amounts around the stem of a plant and watering in gently.

• If available, use a broad spectrum soil microbe mix and add some to the soil. Its best practice to pre mix the microbes in water to ensure even distribution.

• OR you can pre mix with some compost, or older soil or other organic matter, to provide a more even distribution of the amendments.

• Our current branded amendments include our BioBoost Enhance, BioBurst Flower Mix and Yield Master Soil Mix.

• We can provide single material amendments on demand.

Long-term Maintenance

• Regular mulching to protect the soil surface from intense sun and reduce evaporation.

• Consider drought-tolerant cover crops like clover and vetch.

• Soil testing is advisable in order to see which macro and micro nutrients are abundant or deficient. We can advise certain soil conditioners and fertilisers that can correct these imbalances.

• Frequent, maybe monthly, least quarterly or at the very least yearly readings of soil salinity, pH and Ec

Common Misconceptions

• Organic soil does not yield immediate results but offers substantial long-term benefits, especially critical in arid climates.

• Organic gardening reduces, but may not eliminate, pest problems; it significantly improves plant resilience.

Troubleshooting Common Organic Soil Issues in Warm Climates

• Nutrient Imbalance: Regular soil testing and adding organic amendments suited to Mediterranean conditions.

• Pests and Diseases: Utilize beneficial insects, companion planting, and drought-resistant plant varieties.

• Soil Compaction: Periodically add organic matter and use gentle cultivation methods to maintain aeration.

Real-World Success Story

• Highlighting Terra Soil Super Soil pots: Proven effectiveness in Malta's challenging climate, providing healthier yields with reduced water usage.

• Our TerraSoil products are tailored for arid climates, with a particular focus on Malta, being our home base. We have developed numerous products to help improve water retention, aeration, nutrient absorption and increase overall levels of fertility. While altogether improving plant resilience to disease, reduced the number of pests in the surrounding environment and providing a large surface area for the soil natural micro fauna to thrive and excel.
