Why is it not advisable to apply too much organic fertilizer to vegetables?
Traditional agriculture holds that vegetable fields should be heavily fertilized with organic fertilizer, and some vegetable growers even believe that the more organic fertilizer, the better.

Reasonable Application Methods for Water-Soluble Fertilizers
Plants need to absorb various nutrients for growth and development. However, what determines crop yield is the nutrient factor present in the smallest relative amount in the soil, and yield also changes relatively within a certain limit as this factor increases or decreases. This is usually explained using a water-filled wooden bucket. The bucket is made of staves representing different nutrient contents and factors...
