The present invention relates to a concentrated algal extract having a percentage dry matter of between 6 and 100%, the preparation process thereof and also the uses thereof alone or combined with another nutritive, biostimulating or plant-protecting technology, especially to promote plant emergence, growth, development and reproduction and to prevent birds from eating the seeds. The invention also targets a process for applying the concentrated algal extract of the present invention, and also a seed coated with said extract.

Microalgae based compositions and methods of improving emergence and yield of plants by administering an effective amount of a microalgae based liquid composition in combination with other active ingredients including extracts from macroalgae, extracts from microalgae, minerals, humate derivatives, primary nutrients, micronutrients, chelating agents, and anti-biotics are disclosed. A method of applying a microalgae based composition to soil to increase the cation exchange capacity of the soil is also disclosed.
