John Hart is a scientist at Oregon State University Extension Service. Below are is explanations of different fertilizing methods


Make a trench that is about 3 inches deep, place the fertilizer into the trench. The corner of the tool hoe can beĀ  used to make this trench.

The seeds should be sown above and to the side of the trench with the fertilizer.

The roots of the plants absorb the nutrients, and grow well


This method requires the fertilizer to be scattered on the surface.

One should ensure that the fertilizer is spread uniformly


With this method, the fertilizer is spread close to the plants. The fertilizer should be kept off of the leaves. Fertilizer that contains nitrogen, phosphate,

and potash can be lightly embedded into the soil.



  • Because nitrogen in very water-soluble, it reaches the roots of the plants, via rain, and watering
  • One of the most effective methods of phosphorous reaching the roots, is when planting, to place the fertilizer with the phosphorous in bands two inches below the seed. Another method is to till the phosphorous fertilizer into the soil, in spring.
  • Potassium fertilizers can be incorporated using banding or broadcast methods. Ensure that the potassium does not make contact with the roots.
