Seaweed Extract Fertiliser 25%

Seaweed extract fertiliser is a type of organic fertilizer derived from seaweed or algae. It is produced by processing seaweed into liquid or powder form, which retains beneficial nutrients and bioactive compounds naturally found in seaweed.

Seaweed fertilizer, also known as algal fertilizer, marine extract, or seaweed extract, is a nutrient-rich product derived from seaweed. It contains abundant nutrients and bioactive substances, providing plants with essential microelements to promote growth and development.

Seaweed fertilizer primarily comes in two forms: flake and powder. Each form has distinct characteristics suited to different application scenarios and needs.

1. Flake Seaweed Fertilizer

Flake seaweed fertilizer typically appears as rectangular or square flakes, with each piece containing a concentrated amount of seaweed extract. This form offers high stability and uniformity, making it easy to store and use. It is commonly used in small-scale settings like home gardening, balcony planting, or potted plants. It can be applied as a base fertilizer or topdressing fertilizer, supplying essential nutrients such as nitrogen, phosphorus, and potassium to support plant growth.

2. Powder Seaweed Fertilizer

Powdered seaweed fertilizer is a fine, white-to-pale-yellow substance. Its high flowability and solubility allow it to mix easily with water and be rapidly absorbed by plants. This form is ideal for large-scale agricultural applications, including farmland, orchards, and tea plantations, where it can be used as a topdressing fertilizer or basal fertilizer. Rich in seaweed extracts, trace elements, and organic matter, it provides comprehensive nutritional support to enhance plant development.

Selection Guidelines

The choice between flake and powder depends on the plant’s growth stage and soil conditions. For example:

• Seedling stage: Use flake fertilizer as a base fertilizer to meet initial nutrient demands.
• Growth stage: Apply powdered fertilizer as a topdressing fertilizer to replenish nutrients during active growth.

Additionally, prioritize product quality and source integrity by selecting reputable brands to ensure effectiveness.

Both flake and powdered seaweed fertilizers offer unique advantages. Flake forms excel in stability and ease of use for small-scale applications, while powders are favored for large-area farming due to their versatility and rapid absorption. By tailoring the choice to specific needs and ensuring product reliability, seaweed fertilizer can provide balanced nutrition to promote healthy plant growth.
