TL;DR: Seaweed extract is more useful than chemical fertilizer because of its bio-decomposable, non-toxic and eco-friendly property.
Abstract: The application of seaweeds as muck in agricultural farming has been very common from ancient times in the Roman Empire, Japan, China, France, Spain, Britain, etc. Most coastal areas all over the world use seaweeds as bio-fertilizer for crop production. Seaweed extracts are used in different ways like seed treatment, foliar spray and soil application for plant protection and for plant growth promotion. Seaweed extract is more useful than chemical fertilizer because of its bio-decomposable, non-toxic and eco-friendly property. These are the most important reasons to use seaweed extracts in recent years for sustainable agriculture in organic and integrated organic farming. Seaweeds affect agricultural crops for enhancement of plant growth, seedling growth, both root hair and secondary root development. It can also improve nutrient incorporation, fruit setting, resistance properties against pests and diseases, improving the stress management (drought, salinity and temperature). The present review focused on use of seaweed extract in the agricultural system and novel strategies for the use of seaweed extract.

TL;DR: Use of 14 natural raw materials and ultrasound assisted extraction for the production of biostimulants proved that higher plants can be used to obtain valuable products for the application in modern horticulture and agriculture and showed a varied impact on antioxidant activity.
Abstract: This research presents the possibility of using innovative botanical extracts as biostimulants of plant growth to improve plant nutritional value, growth, and development. It is important to increase agricultural production but this process should be carried out in a sustainable way, without causing risks for both the environment and consumers. For this reason, we have focused on the use of 14 natural raw materials and ultrasound assisted extraction for the production of biostimulants. Results proved that higher plants can be used to obtain valuable products for the application in modern horticulture and agriculture. For instance, extract based on Urtica dioica L. showed the highest biostimulatory properties: in the group sprayed with 0.1% extract cabbage seedlings were longer by 31%, while with 1.0% extract of Polygonum aviculare L. roots were longer by 72% than in the control group treated with water. Extracts based on Equisetum arvense L. (0.5%) and Urtica dioica L. (leaf) (0.1%) increased the fresh weight of sprouts by 113% and 112%, respectively. The highest root weight was observed in groups treated with Equisetum arvense L. (0.5%), Polygonum aviculare L. (0.5%), and Urtica dioica L. (leaf) (2.5%)—heavier by 207%, 206%, and 205%, respectively. Most of biostimulants increased the content of pigments involved in photosynthesis (e.g. 156% more chlorophyll for 0.1% Hypericum perforatum L. extract), decreased the content of polyphenols (e.g. 47% less for 2.5% Trifolium pretense extract), and showed a varied impact on antioxidant activity. There is an increasing interest in botanical extracts due to their high content of biologically active compounds and wide variety of application possibilities.

TL;DR: In this paper, the seaweed extract-based biostimulants have been used to improve plant growth and to enhance the yield, and the role of seaweed in plant growth promotion, mitigating plant abiotic and biotic stresses, and improving soil quality is illustrated.
Abstract: Seaweeds are valuable marine resources having multifaceted usages in modern agriculture. Extracts from different seaweeds have been used since many years in agriculture practice to improve plant growth and to enhance the yield. At present, the excessive use of synthetic chemicals and fertilizers imposes a global health hazard and pollutes agricultural lands worldwide. Thus, promoting the use of natural plant growth regulators and fertilizers, such as seaweeds, is recommended with promising outputs. Moreover, the seaweed extract-based biostimulants having plant growth -promoting capacity and aiding in improving the overall plant resilience are highly desirable. In addition, the seaweed extracts can improve the soil health and soil fertility. In this review, the different methods of obtaining the seaweed extract-based biostimulants are discussed. Additionally, the role of such biostimulants in plant growth promotion, mitigating plant abiotic and biotic stresses, and improving soil quality is illustrated and the underlying mechanism is discussed. In addition, some important applications of the seaweed extracts in other than agricultural area have been discussed in brief. Moreover, the future prospects of the seaweed extract-based biostimulants are presented with emphasizing on the economic significance.

TL;DR: The results suggest that the T. ornata and U. reticulata derived SLF could be an effective alternative to chemical fertilizers and warrant further research to investigate its possible use on field.
Abstract: In the current study, Seaweed Liquid Fertilizer (SLF) prepared from the combination of two marine algae namely Turbinaria ornata and Ulva reticulata, was investigated on Raphanus sativus (Radish), Phaseolus vulgaris (Green Pea) and Vigna radiata (Mung). The potentiality was evaluated on the basis of seed germination, plant growth and various biochemical criterions in comparison with chemical fertilizer and plants without any supplement. The seeds of V. radiata, P. vulgaris, and R. sativus were supplemented with 5 different SLF concentrations (20, 40, 60, 80 and 100%) and allowed for germination. Seeds of all the plants showed 100% germination with both 80% and 100% SLF concentrations. It has been observed that 100% SLF treated plants was very effective in enhancing growth rate followed by 80% SLF. The root and shoot length, protein, amino acid, amino acid, carbohydrate and phenol concentration of the plants were found to be maximal at 100% SLF. Among the three plants, P. vulgaris has shown remarkable growth and yield followed by R. sativus and V. radiata. Additionally, the SLF also displayed antagonistic activity against plant phytopathogens such as Rhizoctonia solani, Macrophomina phaseolina, Sclerotium rolfsii and Alternaria solani. The GC-MS analysis of SLF indicated the presence of several bioactive compounds such as cyclopentasiloxane tetradeca-methyl, 3-acetonylcyclopentanone, etc. which are known for its role in plant growth and antifungal activity. The results suggest that the T. ornata and U. reticulata derived SLF could be an effective alternative to chemical fertilizers and warrant further research to investigate its possible use on field.

TL;DR: In this paper, a balanced fertilization strategy that combines use of chemical, organic and /or bio-fertilizers must to be developed and evaluated, and a sound management of fertilization must attempt to ensure both enhanced and safeguard the environment.
Abstract: Plant nutrients are essential for production of crop and healthy food for the word's expanding population. Plant nutrients are therefore a vital component of sustainable agriculture. Increased crop production largely relics on the type of fertilizers used to supplement essential nutrients for plants. The nature and the characteristics of nutrients release of chemical, organic and biofertilizers are different, and each type of fertilizer has its advantages and disadvantages for crop growth and soil fertility. A sound management of fertilization must attempt to ensure both enhanced and safeguard the environment; therefore, a balanced fertilization strategy that combines use of chemical, organic and /or biofertilizers must to be developed and evaluated.

TL;DR: The significance of seaweed extracts in biological agriculture and horticulture is evaluated, regarding environmental aspects of production and use and a survey of the recent literature is given.
Abstract: In biological agriculture and horticulture diluted extracts of seaweed are applied to promote growth, prevent pests and diseases and improve the quality of the products. The efficacy of the extracts is probably based upon plant hormones (mainly cytokinins) and trace nutrients present in the extracts. A survey of the recent literature is given concerning the properties of seaweed extracts, methods of application, their effects and putative working mechanisms. The significance of seaweed extracts in biological agriculture and horticulture is evaluated, regarding environmental aspects of production and use.
