Commercially available chemical fertilizers contain the same nutrients and micronutrients as organic fertilizers such as manure and composted garden clippings. Plants have tiny root hairs that absorb nutrients, and whether the source of the nutrients is organic or chemical is irrelevant to the plants ability to take in the nutrients. Nevertheless, organic fertilizers are better for the health of the plant than are chemical fertilizers alone.

• CPlants often must be provided with nutrients because naturally occurring nutrients in the surrounding soil are depleted or washed away over time. 分析该选项
• DThe typical gardener can't easily know the exact amount and type of nutrients in an organic fertilizer such as manure. 分析该选项
• EChemical fertilizers produced by the leading manufacturer contain nutrients that are no harder for the plants to absorb than those provided by the competitors chemical fertilizer. 分析该选项
