correct Answer ( C )
The soil testing is crucial to determining nutrient levels and guiding fertilizer application . common methods include laboratory analysis, where soil samples are analyzed for various nutrients (N, P, K, etc. ) using chemical or spectroscopic techniques . Field testing methods, while less precise, offer quick estimates using soil test kits that measure pH and some key nutrients . The choice of method depends on the resources available, the level of accuracy needed and the scale of the operation . Accurate soil testing informs precise fertilizer
