Question Statement:
Read the passage and answer the question:
"Precision agriculture relies fundamentally on spatial variability mapping. By deploying global positioning systems and multispectral reflectance sensors, variable-rate fertilizer applicators adjust nutrient delivery in real time. Rather than treating an entire field as a homogenous expanse, inputs are localized to match soil fertility deficits, which curtail excess nitrate leaching into subterranean aquifers and enhances input-use efficiency."
Which of the following statements is most directly supported by the passage?
Options:
- (A) Precision agriculture eliminates the necessity of soil testing and laboratory analyses entirely.
- (B) Variable-rate fertilizer application treats farm fields as uniform zones to simplify tractor navigation.
- (C) Localizing nutrient application based on spatial variability mitigates groundwater contamination.
- (D) Multispectral sensors increase nitrate leaching by accelerating fertilizer chemical absorption.
