Why do farmers use Decision Support Systems (DSS) for fertilization and irrigation?

Farmers utilize Decision Support Systems (DSS) for fertilization and irrigation primarily because of the frequent changes in weather that impact crop needs. These systems analyze various data inputs, including weather patterns, soil conditions, and crop health, providing farmers with insights tailored to the specific circumstances of their fields. Given the unpredictable nature of weather, particularly in agriculture, a DSS can help farmers make informed decisions that optimize the use of resources while maximizing crop yields.

This adaptability is crucial, as crops require different amounts of water and nutrients depending on current environmental conditions. By employing a DSS, farmers can adjust their fertilization and irrigation practices in real-time, ensuring they meet the changing requirements of their crops throughout the growing season. This dynamic approach contrasts with fixed guidelines, which may not take into account the variability present in agricultural conditions, leading to less efficient resource use and potentially lower crop yields.
