Fertilizer Application Methods

a. Constant feed

• Low concentration at every irrigation are much better.
• This provides continuous supply of nutrient to plant growth and results is steady growth of the plant. Fertilization with each watering is referred as fertigation.

b. Intermittent application

• Liquid fertilizer is applied in regular intervals of weekly, biweekly or even monthly.
• The problem with this wide variability in the availability of fertilizer in the root zone.
• At the time of application, high concentration of fertilizer will be available in the root zone and the plant immediately starts absorbing it.
• By the time next application is made there will be low or non-existent.
• This fluctuation results in uneven plant growth rates, even stress and poor quality crop.
