6 Steps to Select the Right Fertilizer

Select the Right Fertilizer

Plants require nutrients to grow. The most important of these are nitrogen, phosphorus, potassium, as well as calcium and magnesium. There are also many other nutrients that plants need in very small quantities, such as boron, manganese, iron, zinc and others. They are called micronutrients, so, as the name implies, they are required in micro doses. On fertilizer packaging, nutrients are always marked with a symbol for the chemical element. You may find out what exactly amount of fertilizer you need with the help of npk fertilizer finder service.

N = nitrogen
P = phosphorus
K = Kalium
Ca = potassium
Mg = magnesium

Important: Always fertilize purposefully. There are special fertilizers for each group of plants.

Step 1 – Determining Nutrient Deficiency

Determining Nutrient Deficiency

Various symptoms indicate a lack of nutrients: poor growth, discoloration of the leaves. Depending on the type of nutrient deficiency, various signs appear, such as lighter leaves, brown or black spots, or dry leaf edges.

Conveniently:  After examining the leaves or plant parts you brought, he can tell what the plant lacks and what fertilizers are needed to eliminate the deficiency.

Important: Leaf discoloration can be caused by heat, too little or too much water, or too much or too little light. Plant protection chemicals can also cause harm, which is reflected in leaf discoloration.

Step 2 – Soil sample to determine the lack of fertilizers.

Soil sample to determine the lack of fertilizers

The nutrients are stored in the soil and are slowly released by microorganisms. Therefore, plants can receive them along with moisture in the soil. A soil sample will tell you how much is in your garden and whether additional fertilization is recommended. For example, the soil in most gardens contains a sufficient amount of phosphorus, and it needs more nitrogen fertilization.

Important: Collect samples from different parts of the flower bed and mix them thoroughly. This is the only way to get a reliable result.

Step 3 – Choosing the Right Fertilizers

Fertilizers are divided into mineral (chemical, synthetic) and organic (natural). Mineral fertilizers dissolve in water, and therefore the plant can easily assimilate them. Benefit: fast absorption of nutrients. Disadvantage: Fertilizer that did not immediately pick up the plant is easily washed off into a deeper soil layer, into which the roots do not penetrate. Organic fertilizers such as horn shavings and cow dung pellets slowly release their nutrients to the soil and plant roots. Advantage: There is very little danger of over-fertilization. Disadvantage: The action starts after a couple of days or weeks.

Convenient: With organic fertilizers, the soil will be safe and the nutrients will be released over time.

Important: “The more the better.” This is the wrong strategy in fertilizer handling. Too high a dosage of nutrients harms the plants.

Step 4 – Application of fertilizers

Granular or granular fertilizers can be placed by hand or using a trolley. Wear gloves when laying as many fertilizers can irritate the skin.

Convenient: Dry fertilizers are easy to dose.

Important: Measure the amount of fertilizer per square meter with a household scale or measuring glass. If you are unsure, you can practice measuring the correct amount using sand.

Step 5 – Spreading the compost

Spreading the compost

After you have placed a layer of compost with a height of 3-5 centimeters on the flowerbed, you should level it with a rake. Digging it up, as is often advised, is not required. Organisms that live in the soil, such as earthworms, will allow organic material to penetrate deeper layers of the soil.

Important: Compost contains a lot of nutrients, this should be taken into account when following additional fertilization. The need for soil and plants in phosphorus and potassium is almost completely replenished by compost. You can add missing nitrogen by adding horn shavings.

Step 6 – Liquid Fertilizer

Liquid Fertilizer

If there is an acute nutritional deficiency, you can quickly correct it with liquid fertilizer. There are liquid fertilizers containing one active nutrient and complex fertilizers containing all the nutrients the plant needs. To prepare a nutrient solution for fertilization, salt or a concentrated fertilizer solution is mixed with water and this is used to water the plants. Liquid fertilizer is also suitable for fertilizing the leaves through which nutrients are also absorbed.

Convenient: Fast effect, also as a foliar fertilizer.

Important: Carefully follow the dosage instructions, because too high a dosage will damage leaves and roots. In the worst case, the plant can die. If in doubt, it is better to make the dosage less than indicated on the package.
