What is organic fertilizer?
Generally the term “organic fertilizer” is used to refer to fertilizer that has gone through minimal processing, where nutrients are still found in their natural forms. This includes manure and compost, which you can prepare yourself, along with items which can be purchased. Inorganic fertilizers generally refer to fertilizers that are synthetic or artificial, and generally are manufactured from petroleum products (yes, fertilizer that is made from crude oil).
Why do inorganic farmers use poisons?
Because inorganic fertilizers do not supply most of the micro-nutrients needed by the soil and plants, soils become out of balance, and disease, insect problems and weed problems multiply. To counter these, the inorganic farmer utilizes poisons (insecticides, pesticides, herbicides) to treat these symptoms.
What is the difference between organic and inorganic fertilizers?
Inorganic fertilizers may grow a greater volume of food, but organic fertilizers grow more nutritious food. Both plants and people need a host of micro-nutrients. Inorganic fertilizers only supply a handful of these nutrients, while organic fertilizers provide many more.
What does it mean when you give plants and soil the nutrients they need?
When you give plants and soil the nutrients they need, it means healthier plants, and greater nutrition for you . If you choose to use only inorganic fertilizers, you are asking for trouble. Why not add in some organic fertilizers as well.
What are the three nutrients that plants need to produce the most?
Soils and plants need so many more nutrients than Nitrogen, Phosphorus and Potassium (also called NPK). But research has shown that it is these three that are the primary nutrients needed to produce bigger yields. To the farmer, with all the expenses involved in farming, coupled together with low crop prices, if he doesn’t produce larger yields, he very well won’t be able to make enough money to stay in business.
Is inorganic fertilizer water soluble?
From that point we have seen a gradual worsening of soils, resulting in increased insect, disease and weed problems. Inorganic Fertilizers are “water soluble”. They are minerals in concentrated form that are readily available to the plant.
What is nitrogen fertilizer?
Again, as the name implies, this type of fertilizer is rich in nitrogen content. Nitrogen gets converted into ammonia when the fertilizer is applied and dissolves when rain or irrigation systems wet the ground. The nutrients from the chemical nitrogenous fertilizer are then carried through the ground into the root system of the plant. Chemical nitrogenous fertilizers usually come in the form of white granules or pellets which are used to fertilize the soil before or during planting.

Why use inorganic fertilizer?
Inorganic fertilizers are generally used to treat sizable industrial fields because they are cheaper and more easily produced on a large scale than inorganic fertilizer. Inorganic fertilizers are also less bulky than organic fertilizers, which allows the plant to carry nutrients more easily from the soil to its leaves and fruits.
Does fertilizer deplete minerals?
However, inorganic fertilizer can also lead to trace mineral depletion over time because most inorganic fertilizers do not put minerals back into the ground like organic fertilizers do. This results in fruit and vegetables with a lower mineral content.
What are Fertilizers?
Fertilizers are chemical substances supplied to the crops to increase their productivity. These are used by the farmers daily to increase the crop yield. The fertilizers contain the essential nutrients required by the plants, including nitrogen, potassium, and phosphorus. They enhance the water retention capacity of the soil and also increase its fertility.

When you are using this fertilizer, place it as close to the roots as possible. If there is a potassium deficiency in your plant, you may see yellowing or browning on the edges of leaves.
What is phosphorus fertilizer?
Phosphate Fertilizers. Phosphorous is a nutrient that plants need continuously. Throughout their lifecycle, phosphorous help to strengthen the root system and stems of a plant. Flowering, seeding, and fruiting can all be improved with phosphorous. Plants with a phosphorous deficiency will experience stunted growth.
Why is potassium important for plants?
Potassium will help your plants to grow deeper and stronger roots. It can also help protect your plants from harm when they are deprived of other nutrients. This nutrient is vital for photosynthesis and has the ability to slow down any diseases that may infect your garden. Potassium fertilizer has a lot of benefits.

Classification of fertilizers by composition
The main criterion by which fertilizers are distinguished from each other is their composition. Based on this characteristic, they are divided into:
Types of organic fertilizers
Organic fertilizers have a complex effect on the soil. Their introduction helps to improve the physical parameters and structure of the soil, stimulate the activity of microorganisms, and replenish the reserves of micro- and macroelements.
Types of mineral fertilizers
The nutrient in the composition of mineral fertilizers is called the active substance (AD), and its content is measured as a percentage. This allows you to calculate the optimal fertilizer application rate depending on the needs of the plants.
Varieties of bacterial fertilizers
There are no nutrients in their composition, but there are bacteria, the activity of which makes it possible to mobilize the accumulation of nutrients in the root layer and improve its general condition.
What are the two types of fertilizers?
With the proper NPK ratio for your soil in mind, you’ll seek out that set of numbers in one of the two main types of fertilizers on the market: organic and synthetic. Advertisement.
How much does synthetic fertilizer cost?
Compared with organic fertilizers, synthetic fertilizers are more affordable (around $.50 to $2 per pound) and improve plants more quickly.
What is a quick release fertilizer?
Quick-release granular fertilizers are comprised of small, solid, water-soluble granules. Gardeners must sprinkle or spread the granules over the soil surface, mix them into the topsoil, and water them in order for the fertilizer to decompose and release nutrients into the soil.
Why use Jobe's fertilizer spikes?
Fertilizer spikes allow gardeners to avoid the hassles of storing fertilizer bags and spreading fertilizer. The user merely has to drive the solid, water-insoluble sticks (like Jobe’s Fertilizer Spikes) into moist soil, where they decompose and release their nutrients.
What is the NPK of fertilizer?
The NPK value represents the percentage by volume of nitrogen (N), phosphorus (P), and potassium (K) that a fertilizer contains. For example, a fertilizer with an NPK value of 16-16-16 contains 16 percent nitrogen, 16 percent phosphorus, and 16 percent potassium (the remainder of the fertilizer comprises filler ingredients). It also means that the fertilizer has an NPK ratio of 1:1:1; that is, it contains equal amounts of the three main nutrients. Similarly, types of fertilizer with the NPK value of 24-8-16 contain 24 percent nitrogen, 8 percent phosphorus, and 16 percent potassium—that’s an NPK ratio of 3:1:2.
Why is slow release fertilizer good?
The slow release diminishes the risk of burning the plant. Controlled-release fertilizers tend to release nutrients at a predictable rate that depends on soil temperature, while the rate of nutrient release in slow-release fertilizers depends on a number of factors including soil temperature, moisture, and pH.
What nutrients do lawns need?
Soil is an important source of key nutrients like nitrogen (N), phosphorus (P), and potassium (K), but it doesn’t always contain them in adequate amounts. That’s why many homeowners rely on commercial fertilizers as a supplement.

What is nitrogen fertilizer made of?
Nitrophosphates are fertilizers made by nitrifying phosphate rock with nitric acid or a mixture of nitric and sulphuric acids, followed by ammoniating the resulting slurry. Afterwards, the slurry is granulated or prilled. Additional nitrogen can then be added, in the form of ammonium nitrate, along with potassium chloride or sulphate, to achieve the desired NPK analysis.
