A biostimulant formulation for improving plant growth and uses thereof

Abstract

A biostimulant formulation for promoting plant growth, comprising: juice obtained from at least one seaweed species; and hydrolysate obtained from at least one seaweed species pulp, wherein the hydrolysate is obtained from the pulp after juice has been extracted. A method of preparing the biostimulant formulation. A method of contacting the biostimulant formulation with palnt to promote the plantgrowth.

Description

technical field

[0001] The present disclosure relates to the field of plant biology. The present disclosure provides biostimulant formulations obtained from juice and juice extracted pulp of at least one seaweed species for improving plant growth. Background technique

[0002] Seaweed-based biostimulants for improving plant growth have long been widely known. Seaweed extracts and suspensions have achieved a wider range of uses and markets than seaweed and seaweed powder. The seaweed species used are generally temperate, growing in cooler waters. Several reviews have covered the use of seaweed extracts for agriculture (Khan et al. J. Plant Growth Regu.l (2009) 28:386-399; Craigie et al. - J Appl Phycol (2011) 23:371-393).

[0003] Currently biostimulants are mainly made from brown seaweed, although the species varies between countries. Some are made by alkaline extraction of seaweed, with any insolubles removed by filtration (eg Maxicrop and Seasol). Others are suspensio...
