Fertilizer Theories

Fertilizer theories explore how nutrients from fertilizers improve plant growth. The main ideas include the Law of the Minimum, which states that growth is limited by the scarcest nutrient, and the Liebig principle, emphasizing that adding missing nutrients boosts growth until all are sufficient. The Nutrient Balance Theory suggests that plants need the right proportions of nutrients, not just more of one. Modern theories also consider soil health, microbial activity, and nutrient interactions. Ultimately, effective fertilization provides plants with essential nutrients in proper amounts and balance, supporting healthy development without causing environmental harm.
