Digital Farming – Interview to an expert

Summary

In this video, expert Juan Pablo from NUTRICONTROL explains how precision agriculture technologies can help farmers reduce nutrient waste by up to 70%, saving money and protecting the environment. By using automated fertigation systems, farmers can apply nutrients more efficiently, ensuring crops get exactly what they need without excess. This approach not only improves yields but also minimizes harmful nutrient runoff, preventing water contamination. Digital farming tools allow farmers to monitor their operations remotely, making agriculture more sustainable and efficient for the future.

Takeaways

• 🌱 Up to 70% of nutrients supplied to crops can be lost, resulting in significant financial waste and environmental impact.
• 💰 Reducing nutrient use by 30–40% is possible without lowering crop yields, which saves money for farmers.
• 🌿 Applying fertilizer too concentrated at once can cause hydric stress and nutrient loss in plants.
• 💧 Continuous, small-dose fertigation during irrigation allows plants to absorb nutrients efficiently.

Q & A

Why can farmers lose up to 70% of the nutrients they apply to crops?

Farmers can lose up to 70% of applied nutrients because fertilizers are often applied in large, concentrated doses that plants cannot absorb all at once. The excess nutrients are washed away by irrigation or rainwater and eventually reach aquifers.

Does reducing the amount of fertilizer necessarily reduce crop yield?

No. According to the expert, farmers can maintain or even increase their yields while reducing fertilizer use by applying nutrients more efficiently and matching the plant’s daily nutritional needs.

What is one major problem with applying fertilizers only once or twice a year?

Applying fertilizers infrequently results in a high concentration of nutrients at once, which can cause hydric stress for the plant and lead to nutrient losses after the excess is washed away.

How does continuous fertigation improve nutrient efficiency?

Continuous fertigation injects small amounts of fertilizer throughout the irrigation process. This allows plants to receive nutrients gradually and consistently, increasing absorption and reducing nutrient loss.

Why was daily fertilizer application difficult in the past?

In the past, applying small daily doses of fertilizer was expensive and technically difficult with traditional irrigation systems. Modern drip irrigation and automated fertigation systems have made it easier and more affordable.

How can farmers reduce fertilizer use while still meeting plant needs?

Farmers can reduce fertilizer use by supplying only the nutrients that the plant needs on a given day. This precise daily adjustment ensures minimal waste and maximum nutrient uptake.

What role do electrical conductivity (EC) sensors play in fertigation systems?

EC sensors measure the electrical conductivity of the soil solution, which indicates nutrient concentration. This data helps adjust the fertigation recipe to ensure the correct nutrient levels are applied.

How do meteorological sensors contribute to fertilizer management?

Meteorological sensors measure environmental factors such as solar radiation. These measurements help determine plant activity levels and adjust fertilizer application based on how much the plant is likely to consume.

Why is controlling the pH of irrigation water important for plant nutrition?

Controlling pH is essential because some nutrients become unavailable to plants when the pH is outside a certain range. Proper pH ensures nutrients remain accessible and prevents chemical precipitation that could damage irrigation systems.

What is digital farming in the context of fertigation systems?

Digital farming refers to using connected sensors, automated equipment, and cloud-based platforms to monitor and control farm operations. Farmers can view and manage data such as nutrient levels and irrigation parameters through mobile applications.

What environmental problem can result from fertilizer losses?

Fertilizer losses can lead to nutrient runoff that reaches aquifers and water bodies, causing eutrophication. This process leads to excessive nutrient accumulation in water, which can harm aquatic ecosystems.

How does precision fertigation contribute to sustainable agriculture?

Precision fertigation reduces fertilizer waste, lowers production costs, improves nutrient efficiency, and minimizes environmental pollution. This makes farming more productive while protecting natural resources.
