“…Biostimulators are recommended to increase the effectiveness and efficiency of traditional soil fertilization. The efficacy of biostimulators was evaluated in many field trials with vegetable crops, however only some researchers reported statistically significant positive effects on the crop yield and crop quality (Blunden & Wildgoose 1977, Abetz 1980, Abetz & Young 1983, Verkleij 1992 (Table 1). Plants were grown on deep mediumheavy alluvial soil with 1.9-2.3% content of organic matter.…”

were used in the study. Seeds were sown at the end of March and transplants were grown in a greenhouse. The plants were grafted on Maxifort F 1 rootstock on April 5, 6 and 21 in the years 2006, 2007, 2008 respectively without the use of biostimulators. In the case of the other combinations each year the following treatments with biostimulators were performed: watering with Goteo 0.1% solution (twice -4 and 2 weeks before planting and three times after planting at three-week intervals), spraying with BM 86 0.1% solution (four times every three weeks starting at the blooming of first cluster). In the control combination plants were neither-nor grafted or treated with biostimulators. Plants were planted in the field at 70 x 100 cm spacing -20 plants per plot. For the ripe fruits analyses the following parameters were determined: dry matter, total sugars, vitamin C, carotenoids and macroelements: N, P, K, Ca.A higher total and marketable yield was obtained after grafting and Goteo treatments. There was a significant influence of grafting and the application of the biostimulators on the content of dry matter and total sugars, however, the highest content of vitamin C and carotenoids were obtained in the control. There was a slight increase of the content of nitrates and calcium in the fruit in the case of grafting and Goteo biostimulator watering treatments, whereas the highest content of potassium in the fruit was obtained in plants treated with BM 86 and phosphorus in the fruits from control combination plants.

“…For several years, experiments using seaweed extract sprays have been conducted on a variety of plants (Aitken and Senn 1965, Stephenson 1966, Blunden and Wildgoose 1977, Blunden et al 1979, Booth 1981, Abetz and Young 1983. Generally, beneficial results have been reported in crop yields (Blunden 1972, Booth 1981, Povolny 1981, Stephenson 1981, Abetz and Young 1983, in the shelf-life of fruit (Skelton and Senn 1969), in seed germination (Stephenson 1981) in resistance to certain pests and diseases (Stephenson 1981 (Fig.…”

A liquid seaweed extract prepared from Ascophyllum nodosum was sprayed on Vitis vinifera leaves. Ultrastructural investigation of different tissues (upper and Iower lamina, main vein area) has proved the absence of major structural aberrations, and consequently the non-toxicity of the product at the recommended doses. Cells have responded to the treatment and the observed effects appear to be reversible.

“…Recently, there has been increased interest in using seaweed extracts in horticultural and agricultural crops (Leclerc et al 2006) because the quality and yield of the crops are enhanced and the condition of the soil is improved (Canales-López 1999). A. nodosum liquid extract has been shown to improve the quality and yield of crops (Abetz and Young 1983;Colapietra and Alexander 2006;Fan et al 2011;Norrie et al 2002) and to reduce fungal disease development (Jayaraj et al 2008). A. nodosum has a potential sustainable harvest of over 70,000 wet tonnes per year from the Irish coast (Hession et al 1998).…”

Factors affecting the microbial digestion of an industrial seaweed-based residue

2012

Commercial preparation of a seaweed extract from the brown alga Ascophyllum nodosum for use as fertiliser and soil improver produces a sludge residue which requires remediation. This residue is rich in nutrients and offers the potential for other value-added products. The residue composition was analysed, a microbial digestion process for the residue was developed, and several factors affecting the digestion process were studied. The residue showed an alkaline pH (8.61±0.39) and 16% (w/w) total solids, which comprised 40.6% mineral, 29.5% fibre, 24.3% lipid, 4.9% protein and 0.5% polyphenols. The optimised digestion system included a 3-day anaerobic phase to decrease pH (from 8.96±0.40 to 7.72±0.38), the addition of an inoculum, followed by a 10-day aerobic phase where the insoluble material was digested. Every 3 days, the solubilised material was decanted and replaced with water to delay metabolite inhibition. The rate of digestion (decrease in insoluble material of 28.6±14.2% over 13 days) was influenced by the initial insoluble (R 2 00.773) and soluble (R 2 0 0.672) matter, the pH at the beginning of the aerobic phase (R 2 00.528) and by the accumulation of solubilised digestion products. A compositional analysis of the insoluble material after digestion showed that the lipid content of the residue was 96% digested and that the proportion of protein increased by 82.4%. Inocula and metabolite inhibition were critical features of A. nodosum residue digestion. Similar organic residues require a carefully chosen inoculum and a minimum initial insoluble content (65-70%) and/or a maximum soluble content (25.30%).
