Seaweeds as plant fertilizer, agricultural biostimulants and animal fodder - a book presentation

K. Bahcevandziev, L. Pereira
The main effects of seaweed extracts (Ascophyllum, Fucus, Sargassum, Saccorhiza, Laminaria, Gelidium and other species), when used as agricultural fertilizers, are better seed germination and higher quality fruit production, with longer shelf life; better use of soil nutrients; more productive crops and plants with greater resistance to unfavorable environmental conditions. Algae also have a long history of use as animal feed. They have a highly variable composition depending on the species, collection season and habitat, and on external conditions such as water temperature, light intensity and nutrient concentration in water. In relation to ruminal fermentation, a high variability of the digestibility values was found among seaweed species and cannot be attributed only to the composition of different nutrients of the algae. The role of marine algae for reduction of methane production is discussed with particular emphasis on novel algae-based feed strategies that target minimal methane emissions without affecting the functionality of the microbiota and overall animal productivity. All this thematic related to the topics Sustainable agriculture, natural feeding, nutrients liquid seaweed, agricultural biostimulants, natural pesticides, among others, is developed in the book published by CRC Press and edited by Leonel Pereira, Kiril Bahcevandziev, and Niles H. Joshi, which here we unveil in a resume about each of the 12 chapters that appear in this work.
