How to Improve Fertilizer Using Efficiency
Key words: Fertilizer Use Efficiency, Fertilizer Application, Fertilizer Use, How MuchFertilizer to Use, Fertilizer Ratio, Plant Fertilizer Ratio, Lawn Fertilizer Ratio, FertilizerApplication Rates, Lawn Fertilizer Application Rates
1. Applying Proper Amount of Fertilizer
Within a certain range, the productivity of crops is positively correlated tofertilizing amount. Excessively increasing total fertilizing amount or singlefertilizer applying amount may cause crop failure. Nitrogen, phosphorous,potassium and trace elements needed by crops are all indispensible. Theirapplying 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 chooseapplication method accordingly.
★ Make rational use of deep placement, concentration placement and beddedplacement.
★ Apply enough base fertilizer, making sure the crops have sufficient fertilizersupply in seedling stage. At later stage of growth apply top dressing to avoidfertilizer shortage. Top dressing can not only meet the crops’ demand fornutrients 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 timebut smaller amount at each. For loamy soil, mainly base fertilizer, basefertilizer and top dressing combined.
★Popularize the use of new high efficient fertilizer such asslow/controlled-release fertilizer, ecological fertilizer, etc. By controlling thereleasing speed of fertilizer nutrient, slow/controlled-release fertilizer canincrease the fertilizer using efficiency at quite a high rate.
3. Rational Fertilizing Time
The critical period of nutrition and maximum efficiency period are two keyperiods for crops absorbing nutrients. The critical period of nutrition is usuallyin the early growth stage. In this period, the crops’ demand for phosphorous isespecially apparent. We should ensure proper amount of nutrients supply. Inthe maximum efficiency period, the requisite amount of one or severalnutrients is large. Applying chemical fertilizer in this period can give play toyield-increasing potential.
Some crops have different sensibility for different nutrient elements. Their rateof absorbtion and utilization for sensible elements is high. We should applyfertilizer in the crops’ most sensitive periods according to their growth periodand fertilizer requirement law.
4. Mixing Use of Chemical Fertilizer and Organic Fertilizer
Organic fertilizer contains comprehensive nutrients. By mixing chemicalfertilizer and organic fertilizer, we could cover the shortage of the singlenutrient of chemical fertilizer. Chemical fertilizer has fast efficiency, while theefficiency of organic fertilizer is lasting. Mixing use of them can complementeach other, fulfill the nutrient supply of the whole growth period of crops. Thebuffering and fertilizer conservation capability of organic fertilizer can helpreduce nutrient loss and further increasing fertilizer use efficiency.
5. Strengthening the Work of Water Management, Promoting FertilizerAbsorption
The available nutrient in fertilizer should be dissolved in water before they canbe absorbed, conveyed and metabolized by plant root system. Irrigation ofproper amount can increase fertilizer use efficiency, but too much or too littlewill cause the decrease of utilization rate.
We should improve the farmland infrastructure, raising the capacity ofpreserving water. Improve the quality of cultivated land, raising soil waterretention and fertilizer conservation capability.
