How to Improve Fertilizer Using Efficiency

Key words: Fertilizer Use Efficiency, Fertilizer Application, Fertilizer Use, How Much

Fertilizer to Use, Fertilizer Ratio, Plant Fertilizer Ratio, Lawn Fertilizer Ratio, Fertilizer

Application Rates, Lawn Fertilizer Application Rates

1. Applying Proper Amount of Fertilizer

Within a certain range, the productivity of crops is positively correlated to

fertilizing amount. Excessively increasing total fertilizing amount or single

fertilizer applying amount may cause crop failure. Nitrogen, phosphorous,

potassium and trace elements needed by crops are all indispensible. Their

applying amount and ratio should be decided by soil fertility and the crops’

characteristics of requiring fertilizers.

2. Use the Right Fertilizing Method

★ Different fertilizer has different characteristics. We should choose

application method accordingly.

★ Make rational use of deep placement, concentration placement and bedded

placement.

★ Apply enough base fertilizer, making sure the crops have sufficient fertilizer

supply in seedling stage. At later stage of growth apply top dressing to avoid

fertilizer shortage. Top dressing can not only meet the crops’ demand for

nutrients in time, but also decrease the nutrients fixation by soil.

Different soil requires different fertilizing method. For argillaceous soil, mainly

apply base fertilizer and early top dressing. For sandy soil, applying more time

but smaller amount at each. For loamy soil, mainly base fertilizer, base

fertilizer and top dressing combined.

★Popularize the use of new high efficient fertilizer such as

slow/controlled-release fertilizer, ecological fertilizer, etc. By controlling the

releasing speed of fertilizer nutrient, slow/controlled-release fertilizer can

increase the fertilizer using efficiency at quite a high rate.

3. Rational Fertilizing Time

The critical period of nutrition and maximum efficiency period are two key

periods for crops absorbing nutrients. The critical period of nutrition is usually

in the early growth stage. In this period, the crops’ demand for phosphorous is

especially apparent. We should ensure proper amount of nutrients supply. In

the maximum efficiency period, the requisite amount of one or several

nutrients is large. Applying chemical fertilizer in this period can give play to

yield-increasing potential.

Some crops have different sensibility for different nutrient elements. Their rate

of absorbtion and utilization for sensible elements is high. We should apply

fertilizer in the crops’ most sensitive periods according to their growth period

and fertilizer requirement law.

4. Mixing Use of Chemical Fertilizer and Organic Fertilizer

Organic fertilizer contains comprehensive nutrients. By mixing chemical

fertilizer and organic fertilizer, we could cover the shortage of the single

nutrient of chemical fertilizer. Chemical fertilizer has fast efficiency, while the

efficiency of organic fertilizer is lasting. Mixing use of them can complement

each other, fulfill the nutrient supply of the whole growth period of crops. The

buffering and fertilizer conservation capability of organic fertilizer can help

reduce nutrient loss and further increasing fertilizer use efficiency.

5. Strengthening the Work of Water Management, Promoting Fertilizer

Absorption

The available nutrient in fertilizer should be dissolved in water before they can

be absorbed, conveyed and metabolized by plant root system. Irrigation of

proper amount can increase fertilizer use efficiency, but too much or too little

will cause the decrease of utilization rate.

We should improve the farmland infrastructure, raising the capacity of

preserving water. Improve the quality of cultivated land, raising soil water

retention and fertilizer conservation capability.
