Which practice can enhance the efficiency of nutrient use in agriculture?

Precision fertilizer application enhances the efficiency of nutrient use in agriculture by ensuring that fertilizers are applied at the correct rates, times, and locations based on the specific needs of the crops and the characteristics of the soil. This practice allows farmers to provide just the right amount of nutrients needed for optimal plant growth, thus minimizing wastage and reducing the risk of nutrient runoff into water sources. By utilizing technology like GPS and soil sensors, precision application can lead to improved crop yields, better soil health, and more sustainable farming practices overall.

In contrast, over-application of fertilizers leads to excessive nutrient levels that can harm the environment and waste resources. Ignoring soil testing results in a lack of understanding of nutrient status and requirements, potentially leading to imbalanced fertilizer applications, which can be inefficient and damaging. Increasing monoculture typically decreases biodiversity, which can negatively impact soil health and nutrient dynamics. Therefore, precision fertilizer application stands out as a crucial practice for enhancing nutrient use efficiency in agricultural systems.
