What is top dressing? How to fertilize high-yield plants
1. Concept and role of top dressing for plants
In farming, top dressing is a common form. Any crop requires us to be proactive. Thus, crop productivity will reach the desired level. So, what is top dressing?
1.1 Concept of top dressing
Top dressingis to apply fertilizerfor plants during the growing and developing stage. The purpose of this is to provide additional necessary nutrients, creating conditions for the plant to grow and achieve the desired yield and quality.
1.2 The role of top dressing
Fertilize the treeThis is a very important job because it directly affects the growth process of the plant. In case top dressing is not performed,Crops are at reduced riskproductivity because tNutritious, susceptible to epidemics…Fertilizing plants is like eating for humans.
2. Purpose of fertilizing plants
After learning about the concept and role of top dressing for plants, we will discuss the purpose of top dressing for plants and farmland as well.
What is the use of fertilizing plants?
2.1 For plants
Top dressing will give plants the nutrients they need.Each type of plant needs to use fertilizer at a different rate.During the growth process, depending on weather, soil, water and pest conditions, we need to apply appropriate care. Top dressing does not cost too much but helps increase maximum crop productivity.
2.2 For planting land
For cultivated land, when applying fertilizer, it means we are maintaining, improving or enhancing fertility. Through improving the quality of arable land, it ensures that both crops and agricultural work develop sustainably. This is something you should do if you decide to engage in long-term agricultural or tree planting activities.
3. Principles of fertilizing plants
Top dressingnot difficult butTo achieve the desired effect or even exceed expectations, we need to have some specific principles when implementing.
How to fertilize plants?
3.1 Apply the right type of fertilizer
Each type of plant needs to be used depending on the stage and characteristics of the cultivated landsuitable fertilizer. This helps limit fertilizer shortage or excess. For example, if you are growing fruit trees, the tree will need a lot of potassium to synthesize protein, starch or other organic substances in tubers, fruits, seeds, etc. Thus, when harvested, fruits and vegetables ensure output quality.
During the growth or development stage,relativesThere must be a balance between many different nutritional factors. Poor, hardened soil requires microbial or biological organic fertilizer to increase humus and microorganisms to improve the soil.Through the use of biological products combined with top fertilizers,The soil will increase in fertility, bringing benefits to crops. Especially for long-term farming, you should pay more attention.
3.2 Fertilize at the right time
Plants have many successive stages of development, each stage requires different nutrients. Types of stoolsfertilize plantsmust be used at the right timenewbrings good results. For example, if fertilizing for flowering: When people fertilize late, the amount of flowers will not be much, reducing efficiency or not meeting the grower’s purpose.Therefore, weNeed to fertilize at the right time.
Therefore, top dressing is divided into several stages corresponding to the growth stage of the plant. To fertilizeachieved performanceFor the best results, people should divide the fertilizer into several times, each time fertilizing at the appropriate time. This helps avoid excess nutrients, being washed away or lostcausewaste.Moreover, fertilizing in the wrong way and at the wrong time can also have a negative impact on the plant.
Each different stage of development will have a corresponding fertilization method.
3.3 Correct dosage
In case if top dressing is applied but too little fertilizer is applied, the plant will not have enough nutrients needed for its current stage of development. While the purpose of fertilizing is to provide nutrients, it is necessary to fertilize at the right dosage so that plants have the best growing environment, thereby bringing about the desired harvest yield.
On the contrary, iffertilize plantsWith too much dosage, of course the plant will have enough nutrients to grow, but because it cannot absorb it all, the rest will be washed away or evaporated. This will cause you to waste money or effort in planting trees. Especially if feces are difficult to evaporate, it will make the environment polluted or unpleasant to those around.
3.4 Correct method
Each stage of development, type of crop, soil characteristics and even the type of fertilizer and fertilization method are different. There will be types of fertilizers that can be buried in the ground, while others can be spread on top. More specifically, fertilizers that evaporate easily and dissolve quickly should be buried deeper than fertilizers that are difficult to evaporate and dissolve quickly.
In addition, if the fertilizer has a quick effect and is easily absorbed, it will be most suitable for top dressing, do not confuse it with top dressing. Fertilizing properly is part of how we can achieve the desired effect in terms of quantity or quality of harvest from crops grown on cultivated land.
Depending on the purpose and type of plant, a corresponding top dressing method is needed.
3.5 Correct weather
Weather is one of the factors that affect the effect of fertilizer in the soil. On rainy days, fertilizer is likely to be washed away very quickly, causing fertilizer loss and plants not being able to absorb nutrients. Not only that, but at this time, because the fertilizer does not have a great effect, you will also lose money and effort.
On the contrary, on hot days, feces will evaporate quickly due to a chemical reaction. This situation can also cause fertilizer loss, so choose the right type of fertilizer or weather to fertilize, helping plants have a good environment to grow.

4. How should top dressing be done to achieve high efficiency?
As said, it worksfertilize plantswill vary based on both the type of tree and the technique of each unit.
4.1 Top dressing according to technique
- Fertilizing trenches: you just need to dig trenches about 1/2 hand width and 1 hand width around the tree, then use fertilizer to fill in and fill the grooves with soil. In many cases, the size of the trench is customized based on the size of the tree stump.
- Hole top dressing: this is a method where you will spread fertilizer around the tree canopy or on the ground until the humidity becomes suitable. If the soil is too dry, you can water after fertilizing, but do not fertilize in holes in case it is raining.
- Top-dressing and fertilization: is a popular method that helps save maximum time and effort, and controls the amount of fertilizer well. You just need to use fertilizer to dissolve with water, then use a tool to water evenly at the base of the tree. In rural areas, this is the most common method.
There are many different top dressing techniques.
4.2 Top dressing according to plant type
Workfertilize plantsEating fruit is not the same as fertilizing vegetable plants. So how exactly are they different?
Fertilize fruit trees
For annual fruit trees, top dressing will take place about 2 or 3 times after the fruit has been harvested – before flowering and after new fruit appears. At this time, top dressing will be very strict, you need to use specific fertilizers accordingly:
- After harvesting: mainly use nitrogen fertilizers.
- Before flowering: mainly use phosphate and nitrogen fertilizers.
- After fruiting: mainly use potassium and nitrogen fertilizers.
Fertilize vegetable plants
As mentionedfertilize plantsEating fruit is not the same as vegetables, because vegetable plants will need fertilization based on two stages: when the plant is small and when it is growing.
- When young: fertilize to help speed up the growth of leaves or stems of vegetables.
- While growing: used to increase yield of fruit and vegetable crops such as kohlrabi, cucumber, bitter melon…
As for any form of top dressing, they will be carried out at a certain frequency every other day, not continuously. This ensures that the plants have time to absorb the nutrients provided, without being “overfed”.
The most effective way to fertilize plants
Normally, the first top dressing will be 1 week after planting. The second time of fertilization is when the plants have flowered, usually 3 weeks after planting. The last fertilization is about 1.5 months and is applied to fruit trees or fruit vegetables such as pumpkin, melon, cucumber, etc.
5. Answer questions related to fertilizing plants
Not all farmers understand the techniques of fertilizing plants. There are many questions surrounding this topic. Here are the important questions:
5.1 Does top dressing need to be combined with base fertilization?
The answer is yes! Top dressing and base fertilization are both important steps in the plant care process. Base fertilizer’s main function is to provide nutrients to plants before growth. Top dressing is intended to supplement nutrients for plants during the growing process. Combining both forms of fertilization above will help plants grow sustainably, achieving the best yield and quality.
5.2 How often should we apply fertilizer?
In fact, the density of top dressing depends on the type of plant. For short-term vegetable plants: People can fertilize 2 to 3 times during the growth cycle. Particularly for fruit trees: We need to fertilize 2 to 3 times/year. The important times to fertilize fruit trees are: Before flowering, after fruiting and after harvest. If it is a perennial industrial plant, you fertilize it 2 to 3 times a year at the beginning, middle or end of the rainy season.
5.3 Can microbial fertilizer be used as top dressing?
The answer is yes, everyone! Microbial fertilizer contains many beneficial bacteria with strong activity to help improve soil effectively. Thanks to it, arable land becomes loose and rich in nutrients to nourish plants. However, you need to know: The effectiveness of microbial fertilizer will be slower than chemical fertilizer. Therefore, we need to harmoniously combine organic and inorganic fertilizers when fertilizing to achieve the highest efficiency.
5.4 Reasons why plants still grow slowly when applying fertilizer
There are many different reasons why plants grow slowly despite being fertilized:
- Fertilizing at the wrong time means the plant cannot absorb the maximum amount of necessary nutrients
- Fertilization that is not suitable for the needs and characteristics of the plant is also the cause of slow growth. People who fertilize too little will not have enough nutrients for the plants. On the contrary, if we fertilize too much, it will cause shock to the plant.
- Fertilizing incorrectly causes nutrients to be washed away or the plant cannot absorb them.
- Unfavorable weather factors, poor soil, and too many pest attacks also affect plant growth, reducing the effectiveness of fertilizers. Therefore, even though farmers fertilize with appropriate doses, the plants still do not have positive changes.
With knowledge aboutfertilize plantsThe above hope will help many people. We hope that our crops will yield high yields, good output quality, and bring big profitsn. Wish you success.
