How to apply fertilizer. If you are a gardener who wants to increase the production of your garden, it may not always be practical to use organic materials, which is why your best option may be to learn how to use it properly—commercial fertilizer (also called “chemical”). By following a few simple instructions, you can help your plants produce more.
Understand what chemical fertilizers are made of. When you buy them, the bag has a list of ingredients that includes the percentage of each substance essential for plant development.
Should to know How to apply fertilizer before start
These three substances are represented by the acronym “NPK” on most bags. Here’s what it means. N for nitrogen. It is essential for leaf growth and is used in large quantities when you want a larger plant or thicker foliage. Some plants extract their nitrogen from the atmosphere.
For example, legumes such as beans and peas fall into this category. It is another chemical that plants need to stay healthy. It is produced in phosphate mines or from industrial waste, and plants use the phosphorus it contains in their cellular processes.
Phosphate is more common in soils with a lot of clay and is quickly drained from sandy marl or more sandy soil. It is represented by the letter “P” on the label.
K for potash. It is the third chemical that you will find in the composition of the fertilizer. It is also used by plants at the cellular level and is necessary for the production of flowers and fruits. It is represented by the letter “K,” the chemical symbol for potassium.
Learn about the nutrients your plants need. Lawns and other decorative plants might appreciate a fertilizer with a lot of nitrogen and moderate amounts of potash and phosphate, while garden plants might prefer a more specialized fertilizer with a lesser amount of an element or more another. If you are not sure of the exact needs of your plants, you should inquire at a garden center or contact the chamber of agriculture near you to obtain this information.
Test your soil
This will give you a better idea of the substances needed for the plants you grow there. Garden centers and farm produce stores can provide you with kits to take soil samples and analyze them.
This kind of test can be done for a particular plant or used to calculate the exact fertilizer requirements. If you do not do a soil test, you will probably put too much or not enough fertilizer.
Apply the fertilizer
There are many different methods for applying it, for example, directly by hand, spreading it, diluting it, or using a machine to mix it with the soil at the same time. Each of these methods depends on the amount of fertilizer you want to put, the size of the area in question, and the size of the plants for which you are putting fertilizer.
You can apply it before installing the plants on a small area by dispersing it over the entire surface and then turning the soil over. Apply between half a kilo and a kilo on an area of 10 m2 maximum to avoid putting too much.
Spreading is more practical over a large area, and it is generally advisable to put between 200 and 400 kg per hectare using a calibrated spreader that you push by hand or that you pull with a tractor. After applying it, turn the soil over to mix the fertilizer in to reduce the risk of rain drains.
To avoid poisoning your plants, especially the young ones, dilute the fertilizer in a bucket or watering can be filled with water. Use this solution to water the plants in question.
This method will also help them absorb it more easily. After watering them with the fertilizer, water them again with pure water. This second watering allows the fertilizer to flow, which could remain on the leaves and stems. If you leave them, you could damage and destroy them.
Direct application to individual plants or plants in a row can be made by pouring the fertilizer into a clean, dry bucket before advancing by pouring.
