Discover why naturally Cold Fermented Solutions are so good
for Soil and Crop Nutrition

Liquid fertilisers have emerged as a popular choice for farmers and gardeners due to their ability to offer sustained absorption for both foliar and root applications.

4 Reasons Why Liquid Biofertiliser Benefits Crops

Unlike traditional solid fertilisers, liquid fertilisers can be applied directly to the leaves or through the soil, providing plants with immediate access to essential nutrients.

One of the key advantages of liquid biological fertilisers is their ability to be absorbed by plants through foliar absorption. When sprayed onto leaves, these fertilisers are quickly taken up by the plant’s foliage, allowing for efficient nutrient uptake. This method is particularly beneficial when plants are experiencing nutrient deficiencies or stress, as it provides a rapid solution.

Alternatively, liquid fertiliser, such as Fish Hydrolysate or Seaweed Biological Fertiliser, can also be applied through root application via soil penetration. These fertilisers penetrate the soil rapidly upon application, ensuring that nutrients are readily available for plant roots to absorb. This method is especially effective in promoting healthy root development and overall plant growth.

1. Liquid Fertiliser Delivers Prompt Mineral Absorption

The prompt absorption and utilization of nutrients provided by liquid fertilisers contribute to improved crop yields and healthier plants. Additionally, their versatility in application methods makes them suitable for various farming practices and gardening needs.

Liquid fertilisers offer a convenient and effective solution for delivering essential nutrients to plants. Their ability to provide sustained absorption through both foliar and root applications makes them an invaluable tool in modern agriculture and horticulture practices.

2. Liquid Biological Fertiliser Contains ‘Living’ Biology

Activated with beneficial microorganisms, liquid biological fertilisers that are biologically alive, and enriched with ocean minerals from fish and seaweed, offer a sustainable and effective solution for promoting plant growth and building fertility in the soil.  The living biology in liquid biological fertilisers have two necessities in order to survive; food and water.  Therefore, technically dry fertilisers are not biologically active.

3. Biofertiliser Offers Easy to Uptake Bio-available Minerals

These liquid biological fertilisers, often referred to as foliar fertilisers, harness the power of natural ingredients such as kelp (seaweed) and fish to provide essential nutrients to plants in a readily available form.

Liquid Seaweed Fertiliser, derived from ocean kelp, is rich in trace elements, vitamins, and minerals that are beneficial for plant health. Seaweed helps stimulate plant root development, enhance nutrient uptake, improve soil structure, and increase resistance to environmental stressors. Additionally, liquid seaweed kelp fertiliser contains natural growth hormones like auxins and cytokinins that promote overall plant growth and development.

Liquid Fish Hydrolysate Fertiliser is another type of liquid fertiliser that is derived from the remains of fish or fish by-products. It is packed with essential nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, and trace elements. Liquid fish fertiliser not only provides immediate nutrition to plants but also contributes to improved soil fertility over time.

Furthermore, both seaweed kelp and fish, as biological fertilisers, offer a comprehensive solution for promoting plant health. The beneficial microorganisms present in these fertilisers help break down organic matter in the soil into simpler forms that can be easily absorbed by plants’ roots. This enhances nutrient availability while improving soil structure and microbial activity.

4. Organic Liquid Fertilisers are Safe for the Environment

Using organic liquid fertilisers, biologically activated with beneficial microorganisms, and rich ocean minerals from fish and seaweed, can be an eco-friendly alternative to synthetic chemical-based options.

Biologically activated liquid fertilisers provide a natural source of nutrients while supporting sustainable farming practices. Whether used in commercial agriculture or home gardening settings, organic liquid biological fertilisers have shown promising results in enhancing plant growth while minimising environmental impact.
