The Importance of Biology in Soil

In agriculture, the focus has been placed on chemical inputs and technological advancements for increased productivity. However, an overlooked aspect of agriculture is the health of the soil which is a medium for plant growth and also biological interactions that are vital for healthy ecosystems.
The soil microbiome is a community of microorganisms, including bacteria, fungi, viruses, and protozoa, that live in the soil. This system plays a vital role in nutrient cycling, soil structure, disease suppression, and overall plant health. These microorganisms break down organic matter, releasing nutrients and detoxifying substances. They also form symbiotic relationships with plant roots, aiding in nutrient absorption and protection against pathogens.
Agricultural practices, such as excessive use of chemical fertilisers, pesticides, and intensive tillage, have led to a decline in soil biology. These practices disrupt the soil microbiome, reducing microbial diversity, and disrupting the processes they perform. This decline in biology has effects on soil fertility, nutrient availability, water retention, and ecosystem health.
To reverse the damage and ensure the long-term sustainability of agriculture, it is essential to put biology back into the soil by:
1. Organic Management
Adding organic matter, such as compost, crop residues, and cover crops, enhances soil biology. As microorganisms break down organic matter, they release nutrients, increase soil fertility, and improve soil structure.
2. Minimising Chemical Inputs
Reducing chemical fertilisers, pesticides, and herbicides helps preserve the diversity and activity of soil microorganisms. These inputs can have adverse effects on beneficial microbes, leading to imbalances in soil ecosystems.
3. Crop Rotation
Rotating crops and diversifying plants help maintain a balanced soil microbiome. This approach boosts microbial diversity, enhances nutrient cycling, and suppresses plant diseases.
4. Conservation Tillage
Conservation tillage practices, such as no-till or reduced tillage, protect soil structure and soil microorganisms.
Restoring soil biology offers numerous benefits:
1. Nutrient cycling performed by soil microorganisms makes nutrients available to plants, reducing the need for synthetic fertilisers.
2. Beneficial microorganisms can suppress harmful pathogens, reducing the incidence of disease.
3. An active soil microbiome helps plants withstand harsh environmental conditions.
4. Soil biology improves soil structure, thereby conserving water and preventing soil degradation.
BioIQ aims to reduce the use of synthetic fertilisers whilst improving soil health, migrating farmers to something more cost-effective and sustainable. Through proprietary technology, we utilise beneficial bacteria in a variety of environmental and agricultural applications.
