What is agricultural fertilizer?

Fertilizer is not just food for plants; it also improves the physical, chemical, and biological properties of the soil. Some fertilizers, such as organic fertilizers, improve soil aeration and water retention, while others, such as mineral fertilizers, provide a concentrated and rapid dose of a specific element.

The importance of agricultural fertilization

Agricultural fertilizer is any natural or manufactured substance added to the soil or plant tissues to provide the nutrients needed for growth. Not all soils are created equal; some are deficient in nitrogen, while others lack phosphorus or potassium. Fertilizer is used to address these deficiencies. Here's the importance of agricultural fertilization:

Increased productivity: Balanced fertilization can increase crop yields by 30% to 50% or more. Plants that receive complete nutrition grow faster and produce more fruit.
Improved quality: Deliciously flavored tomatoes, vibrant flower colors, and large fruit size are all direct results of good fertilization. Phosphorus, for example, is essential for root growth and plant development.
Stress resistance: Well-nourished plants are stronger in the face of harsh conditions such as drought, high heat, or attacks by pests and diseases.
Promoting soil health: Organic and bio-fertilizers in particular revitalize the soil, increasing the activity of beneficial microorganisms, thus improving soil structure in the long term.

Fertilizers are generally divided into three main categories according to their source and method of action:

Organic fertilizers: These come from living, natural sources (animal or plant). They improve soil structure, increase its porosity, and provide the soil with nutrients slowly and sustainably.
Chemical (mineral) fertilizers: These are chemically manufactured or extracted from minerals, and are concentrated and fast-acting, thus considered a quick solution for treating acute deficiencies.
Biofertilizers: They contain beneficial microorganisms that enhance the plant's ability to absorb nutrients.

Types of organic agricultural fertilizers and how to use them

Organic fertilizers are those that come from a living, natural source (animal or plant waste). They include manure (sheep, cow, and poultry manure), compost (manufactured organic fertilizer), and green manure (plants grown and tilled into the soil).

Benefits

Long-term soil improvement: It not only nourishes the plant, but also improves soil texture, increases its porosity and water retention capacity.
Slow-release nutrients: The organic matter decomposes slowly, providing sustained nutrition to the plant for several months without burning the plants.
Environmentally safe: Reduces the need for manufactured chemical fertilizers.

How to use

Add well-rotted (mature) compost to the soil several weeks before planting. Avoid using fresh manure as it may contain weed seeds or pathogens. For home gardens, add a 2-5 cm layer of compost around the plants each season.

When should you use chemical and mineral fertilizers and when should you avoid them?

Chemical fertilizers are manufactured or extracted mineral salts containing high and concentrated proportions of nutrients such as urea (46-0-0) or superphosphate.

When to use

In cases of severe deficiency: When the plant shows clear deficiency symptoms (such as yellowing leaves due to nitrogen deficiency), a quick solution is needed. Chemical fertilizers are absorbed immediately.
For commercial farming: because it is relatively cheaper and gives quick and amazing results in terms of production volume.

When to avoid it

If you are a beginner: Overdoses of it kill plants instantly; this is called compost burn.
In sandy or very poor soils: because it is quickly washed away by irrigation water (filtration) without the plants fully benefiting from it, causing groundwater pollution.
When striving for sustainable organic farming.

Your complete guide to understanding NPK fertilizer numbers and choosing the right ratio

On any fertilizer container, you will find three numbers separated by a hyphen, such as 20-20-20 or 10-52-10. These numbers represent the percentage of the three macronutrients:

N (nitrogen): Responsible for leaf growth and vegetation. High number = leafy plants.
P (phosphorus): Responsible for the growth of roots, flowers, and fruits. High number = strong roots and many flowers.
K (potassium): Responsible for general health, disease resistance, and fruit quality.

How do you choose the percentage?

For new seedlings: Use a high-phosphorus fertilizer such as 10-52-10 to encourage root growth.
For leafy plants (lettuce, spinach, ornamental greens): Use a high nitrogen fertilizer such as 30-10-10.
For flowering and fruiting plants (tomatoes, roses, peppers): During the flowering stage, use a high phosphorus and potassium fertilizer such as 10-20-20.
For general maintenance: Use a balanced fertilizer such as 20-20-20.

What is the difference between foliar and liquid fertilizers?

Here's the difference between foliar and liquid fertilizers:

Foliar fertilizers: Sprayed directly onto the plant leaves. They are absorbed very quickly within 24 hours. Ideal for treating acute deficiencies or during critical growth stages such as fruit set. However, their effect is short-term.
Liquid fertilizers (soil fertilization): These are added to water and applied to the soil. They are absorbed by the roots. Their effect is slightly slower than foliar application but lasts longer, making them ideal for continuous basic nutrition.

How do you choose the right fertilizer for your soil and crop?

There are many types of agricultural fertilizers, each with its own benefits, and choosing the right one depends on three pillars:

Know your soil: Analyze the soil. Is it sandy (loses water quickly) or clayey (retains water and salts)?
Know your crop: Do you want leaves (nitrogen) or flowers and fruits (phosphorus and potassium)?
Know your goals: Are you in a race against time to achieve maximum commercial production? Or do you want a sustainable home garden?

What are the modern trends in agricultural fertilization in Saudi Arabia?

The agricultural sector in the Kingdom has witnessed a surge in the adoption of modern technologies to overcome the challenges of the arid climate:

Hydroponics: It relies entirely on special nutrient solutions (high-purity liquid fertilizers) because there is no soil.
Fourth-generation (nano) fertilizers: Using nanotechnology to manufacture highly concentrated and intelligent fertilizers that release nutrients based on the plant's actual needs.
Computerized drip irrigation systems: In these systems, fertilizers are injected with extreme precision according to a computer-controlled schedule, saving up to 40% on water and fertilizer.

Frequently Asked Questions

What is the best fertilizer for all types of houseplants?

There is no one-size-fits-all fertilizer, but a balanced NPK fertilizer (20-20-20) diluted to half strength is a safe and good option for green houseplants. For flowering plants, use a fertilizer higher in phosphorus (10-30-20).

Can all fertilizers be mixed together?

No, mixing some fertilizers, such as calcium, with sulfur or phosphorus can cause chemical reactions that precipitate as insoluble compounds, preventing the plant from absorbing them. Always read the instructions.

How many times a week should I fertilize my plants?

It varies depending on the type of fertilizer and the plant. The golden rule: liquid fertilizer can be applied weekly or bi-weekly, while slow-release granules can be applied every 3-6 months.
