As the name suggests, 유기 비료 is a kind of fertilizer that is produced by natural or natural ingredients. As agriculture has grown in recent years, more and more farmers and food producers consider using organic fertilizers in their plants. These organic fertilizers can reduce the chemical damage to soil and provide healthy plants to humans. In this article, we will introduce the pros and cons of organic fertilization, the types of fertilizers, the advantages, and how to use them.

Organic Fertilizer Definition

Official Definitions

According to the USDA’s National Organic Program (NOP 205.203), organic fertilizer ingredients must come from plant, animal, or mineral resources; chemical ingredients are not allowed. There is a strict set of criteria for identifying whether a fertilizer is organic or not. Just like the difference between a home-cooked meal and fast food for your plants.

Simply explained, organic fertilizer can also be called organic manure. So, animal waste and animal and plant residues are rich in natural nutrition. Such as seabird guano, bone powder, phosphate rock, etc.

Key Components

Organic fertilizers contain three main nutrients—Nitrogen (N), Phosphorus (P), and Potassium (K)—but in gentler ratios than chemical alternatives. The FAO’s 2022 report shows typical NPK ratios:

Fertilizer Type Avg Nitrogen Avg Phosphorus Avg Potassium
Chicken Manure 1.1% 0.8% 0.5%
Chemical 10-10-10 10% 10% 10%

What Makes Organic Fertilizer Different from Synthetic Fertilizer

Organic vs Synthetic fertilizer​

Synthetic fertilizers are made from chemicals that people make and are meant to give plants a quick boost of nutrients. Organic fertilizers, on the other hand, work more slowly and steadily. They give your soil nutrients over time and improve its overall structure and microbiome.

Table for Quick Comparison

기능 유기 비료 Synthetic Fertilizer
출처 Natural (plants, animals, minerals) 인공 화학 물질
Release Speed Slow and steady Fast-acting
토양 건강 Improves over time May degrade soil structure
Environmental Impact 낮음 Can be high
Risk of Overfeeding 낮음 High (can burn plants)

Types and sources

Organic Organic fertilizer ingredients are main coming from mineral, animal waste, plants from agriculture, etc.

  • Organic fertilizers made from plants

    Some examples are compost, seaweed extract, green manure, and alfalfa meal. They break down quickly and are full of micronutrients.

  • Organic fertilizers made from animals

    Think of things like blood meal, bone meal, fish emulsion, and manure. These are full of nutrients and help plants grow strong, especially nitrogen and phosphorus.

  • Organic Fertilizers Made from Minerals

    These things come from the ground, like greensand, lime, and rock phosphate. They slowly give the soil important minerals and help it stay together.

How to Make Organic Fertilizers At Home

The best organic fertilizers don’t cost a lot of money. You can also make your own at home, which is the cheapest, doesn’t need any packaging, and is better for the environment.

Some of the most common organic fertilizers that people make at home are:

Compost is a mix of food scraps, paper, and plant waste from farming. You need a special container that lets bacteria break down the organic matter and turn it into fertilizer.
Manure from cows, chickens, or rabbits. You’ll also need a special place to keep and handle the animal waste so it has time to break down completely before you spread it on your land.
If you have a fireplace, wood ash is good. Wood ash has a lot of minerals and elements in it, like potassium, magnesium, calcium, and phosphorus. It can be a good fertilizer that helps you get rid of snails and slugs in your garden. You can also use it to make compost.
Water for cooking veggies. Yes, the water you use to cook vegetables, eggs, and even spaghetti adds nutrients to your plants and keeps the soil moist. But make sure to wait until the water is at room temperature before you use it.
Eggshells. Save all the eggshells, let them dry, and then grate them to give your garden food that is high in calcium.
