Application Rates

 

Seaweed-based biostimulants, particularly those derived from Ascophyllum nodosum, have gained recognition for their ability to enhance plant growth and resilience. These biostimulants contain a complex array of bioactive compounds, including vitamins, trace elements, phytohormones, and polysaccharides, which collectively support improved rooting, stress tolerance, and overall plant health.

Croptek Bio offers a range of seaweed-based products, such as SeaFol, SeaPhyte, and Maxicrop, each formulated to deliver these benefits across various crop types. These products are suitable for use in both conventional and organic farming systems, providing flexibility in application.

The effectiveness of seaweed biostimulants is influenced by factors like crop species, growth stage, and environmental conditions. For instance, foliar applications of seaweed extracts have been shown to promote increased germination rates, seedling vigor, and enhanced root systems, leading to improved crop productivity.

To assist in optimizing the use of seaweed biostimulants, the following chart outlines recommended application rates for different crop types. These guidelines are designed to help achieve the best results while ensuring efficient use of these natural products.  If you have any questions contact the team on 01553 886393 or 07860 877616, alternatively email info@croptekbio.co.uk
