Slow-release fertilizer is a term that refers to how fast the nutrients of the fertilizer are taken up by the plants. This type of fertilizer releases nutrients to plants slowly after each irrigation with minimum losses through leeching. Note that this fertilizer is available in dry blends or granular formulas. Generally, slow-release fertilizer are easy to spread and are suitable for covering broad areas of plantations.
In addition, slow-release fertilizer are easy to use and provide long-lasting results on the palm oil tree, which is an alternative to quick-boost fertilizer. This fertilizer usage are far more convenient and require less frequent application as plants does not receive amounts of fertilizer all at once. However, the rate of release is determined by the solubility of the ingredients of the fertilizer are; among other things like the existing soil and the weather condition.
How does it works?
Slow-release fertilizer exist in two types of components which are organic and slowly soluble or coated fertilizer.
Before the nutrients are available to plants, the nutrients in the organic fertilizer will be broken down by microbial activity in the soil. Thus for the fertilizer to be effective, the soil have to be moist and warm enough to encourage organisms activity in the soil.
In slowly-soluble or coated fertilizer(better known as non-organic fertilizer), the method of the release of nutrients are almost the same. The release of nutrients depends on soil moisture and temperature.
Also, the nutrients are released over a period of time, some lasting up to 12 months, so fewer application is needed. It’s important to know that slowly-soluble or coated fertilizer provides good colour without excessive leaf growth.
Using slow-release fertiliser benefit palm oil plant in many ways that include reducing the run off loss of applied nutrients on oil palm cultivation and also the shortage of labour for company in the plantation sector.Leave a reply
