Which Type of Spreader Is Best for Applying Fertilizers?

Choosing the most suitable fertilizer spreader for fertilization mainly depends on the type of fertilizer (granular/liquid), the area of fertilization, the type of crop, and the precision requirements. Here are several common types of fertilizer spreaders and a comparison of their advantages and disadvantages:

✅ 1. Double Disc Spreader

Application scenario: Medium to large-sized farmland, granular fertilizer application.

advantage:

The spreading width is large (up to 12-36 meters).

The efficiency of spreading is high, making it suitable for large-scale operations.

It can be used in conjunction with Beidou/GPS to achieve precise variable rate fertilization.

Disadvantages:

The accuracy of edge application is slightly poor, and a reasonable route planning is required.

There are requirements for particle uniformity.

✅ 2. Drop Spreader

**Applicable scenarios: small-area precision fertilization, orchards, nurseries, and vegetable fields.

advantage:

Even distribution, precise control, with almost no drift.

It is particularly suitable for precise fertilization near the roots of crops.

Disadvantages:

The sowing width is narrow, the efficiency is low, and it is not suitable for large-scale operations.

✅ 3. Pneumatic / Airflow Spreader

**Applicable scenarios: Precision agriculture, large-scale farms pursuing variable rate fertilization.

advantage:

The fertilizer is conveyed by airflow, ensuring even distribution.

It can precisely control the amount of fertilizer applied to each area and supports intelligent agricultural systems.

Disadvantages:

High cost and complex structure.

The operation and maintenance threshold is high, making it suitable for professional farms.

✅ 4. Liquid fertilizer spreader (liquid spray type)

**Applicable scenarios: foliar fertilizer, irrigation liquid fertilizer, integrated pesticide application.

advantage:

It absorbs quickly and can be mixed with pesticides for spraying.

It is particularly suitable for supplementing nutrient deficiencies and topdressing.

Disadvantages:

It is prone to drift or burn the leaves, and requires high weather conditions (light wind, sunny days).

The fertilization cycle is relatively short, necessitating multiple applications.
