Nutrient-Poor Farms Get a Vitamin Boost From Zinc Mines

The video discusses zinc's critical role in human health and its deficiency in Chinese farmland. Teck Resources is conducting a project in China to address zinc deficiency, which affects crop yields and nutritional content. The project has shown promising results, with increased crop yields and zinc content. However, challenges remain in zinc fertilizer application due to varying soil and crop types. The potential demand for zinc fertilizers is significant, with the possibility of tripling if used globally.

What is one of the main reasons for zinc deficiency in soils?

• Over-farming and climate change

• Lack of sunlight

• Excessive rainfall

• High levels of nitrogen

What was the initial purpose of Teck Resources' project in China?

• To develop new farming techniques

• To reduce water usage in agriculture

• To address zinc deficiency in children

• To increase rice production

What significant result has Teck Resources observed in their zinc project?

• Decrease in soil acidity

• Increase in crop yields by 20%

• Reduction in water usage

• Higher nitrogen content in crops

Why is the adoption of zinc fertilizers not straightforward?

• Zinc is not available in all regions

• Zinc is harmful to some crops

• Different soils absorb zinc differently

• Zinc is too expensive

What could happen if zinc fertilizers were used globally as recommended?

• The demand for zinc would decrease

• The demand for zinc would triple

• The demand for zinc would remain the same

• The demand for zinc would double
