Modern agricultural techniques involve the use of advanced technologies and practices to improve crop yields and efficiency. Techniques such as precision farming utilize data and GPS technology to monitor and manage field variability, ensuring that crops receive the right amount of water, nutrients, and pesticides. This approach minimizes waste and enhances productivity. Another important method is hydroponics, which allows plants to grow in nutrient-rich water instead of soil. This technique can be used in urban areas and reduces the need for large land spaces. Additionally, genetic modification helps create crops that are more resistant to pests and diseases, further increasing food security.
