When it comes to ensuring robust plant growth, it’s imperative to consider macro- and micro-nutrients that are crucial for a farm’s soil structure and health. Dr André Cilliers, the marketing manager at AECI Plant Health, shares the characteristics necessary to create the ideal environment for plants to flourish and much more.
According to Cilliers, soil health is all about three key components: structure, chemistry, and biology. Ideal soil structure allows for good drainage, air circulation, and water retention. It should also be rich in organic matter and have a balanced pH. Practices like conservation tillage, cover cropping, and crop rotation can all contribute to a healthy soil structure.
“Cover cropping enhances soil structure by increasing organic matter, improving root penetration, controlling erosion, and promoting nutrient cycling. Overall, adopting conservation-minded practices can contribute to the maintenance and improvement of soil structure in agricultural systems,” he explains.
Organic and inorganic fertilisers
The two main types of fertilisers used to supplement nutrients in soil are also discussed. They are inorganic and organic. The latter releases nutrients slowly and promotes beneficial microbial activity in the soil. However, their exact nutrient composition can be difficult to determine.
“While these nutrients are essential for plant growth, it’s important to ensure they are available in appropriate quantities and balanced ratios to prevent deficiencies or toxicities, which can negatively impact plant health and productivity. Soil testing and proper fertilisation practices are key to maintaining optimal nutrient levels for healthy plant growth,” he says.
Cilliers emphasises the importance of monitoring soil health. By regularly testing their soil, farmers can track improvements and make informed decisions about their soil management practices. Healthy soil is a valuable asset that leads to increased crop yields and a more sustainable agricultural future.
In this episode, Cilliers also discusses:
- Monitoring soil health over time;
- Understanding micronutrients and macronutrients; and
- Developing a nutrient management plan.
