Effective use of organic fertilizers to have a bountiful harvest

Organic fertilizer is one of the important and indispensable fertilizers in the formation and development of plants. However, understanding it correctly and how to use it properly and achieve the best results is an issue that has not received much attention.


Organic fertilizer is fertilizer that contains nutrients in the form of organic compounds. The nutrients contained in organic fertilizer cannot be used directly by plants but must be decomposed through the activities of microorganisms and physical and chemical effects in the soil. This feature is greatly related to the way organic fertilizer is used, with the basic principle being to make the fertilizer decompose quickly, converting nutrients from indigestible to easily digestible forms to promptly provide nutrients to plants.

Because of the above characteristics, organic fertilizer must be processed before use to decompose, especially fresh organic fertilizers such as manure, garbage, and peat. Unprocessed manure will be slowly absorbed by plants. Fresh manure also carries many factors that pollute the soil. In addition, during the natural decomposition process, it also produces some substances that are harmful to plant roots (organic poisoning).

Organic fertilizers are mainly used as top dressing before planting, so if farmers use top dressing, they must apply it early before the plants grow strongly or before flowering (for perennial plants).

The way to fertilize is to spread fertilizer evenly on the ground or fertilize in rows or holes. Green manure is plowed into the ground. Fertilizer dosage depends on soil type and plant type. The average amount of composted manure is from 500 kg – 5 tons/ha (depending on manure quality). Microbial fertilizer applied in new soil, shallow soil, after a flooded season, where plants with symbiotic bacteria have not been planted… is highly effective.

In particular, people need to firmly grasp the principles when applying organic fertilizer and the most effective way to use organic fertilizer that BSF Smart Farm is about to share below.

Organic fertilizer brings many great benefits, including:

Organic fertilizers supplement essential nutrients for comprehensive and balanced plant growth, and are a place to store nutrients for plants;

Microorganisms in the soil love organic fertilizers, quickly decomposing substances to help plant roots easily absorb nutrients, limiting plants from root diseases such as yellow leaves and root rot,…

Organic fertilizer increases soil aeration and porosity, provides humus to help improve soil structure, helps soil retain moisture, water and fertilizer longer, helping to increase the quality of agricultural products for a bumper harvest.

Plants can only absorb soluble organic forms with small molecular sizes. So if you apply untreated fertilizers to the soil, it takes a certain amount of time to decompose before the plant can absorb it.

Organic fertilizers are compatible with most plants. However, you should still try using different dosages to ensure the desired effect and not cause waste.

You can use organic fertilizer to top and fertilize plants, but the substances in organic fertilizer often have slow effects. Therefore, you should prioritize using organic fertilizer to fertilize plants, which is more effective.

If you apply organic fertilizer to your plants, you must fertilize them early before the plants flower. You can dig a trench or loosen the soil around the canopy, fertilize and cover it with soil.

You should fertilize at least 5cm from the base of the tree, giving priority to fertilizing outside the root tip. And limit top dressing with short-term plants.
