Why Seaweed Extract Is Key to Sustainable Agriculture – and Feeding Vegans
Bringing meat from farms to factories, grocery stores and then your dinner table produces a hefty carbon footprint. Meat production creates one-fifth of global emissions and the world’s cattle population produces more greenhouse gases than the United States population combined. More North Americans are trying to lower emissions by adopting eco-conscious, vegetarian or vegan diets, […]
Is Drought Harming Your Crops? Boost Water Use Efficiency with Acadian Plant Health™ Products
How efficiently are crops using the water they receive? Growers want to know. Though plants are often tougher and more drought-resistant than we imagine, there are limits to their resilience. More frequent and longer periods of drought worldwide are placing an extra strain on plants’ ability to function at optimal levels, cutting into their performance […]
Overcoming Abiotic Stress: Crop Inputs Are Vital to Drought Stress Management
When placed under extreme abiotic stress, crops initiate self-preservation mode. They decrease transpiration and photosynthesis, and instead store water and vital nutrients in more essential parts of the plant. Though the plants now have a better chance of survival, their decreased growth and productivity can affect growers’ profits because the size, quality and yield of […]
Thermal imaging of soybean response to drought stress: the effect of Ascophyllum nodosum seaweed extract
Abstract Previous experiments have demonstrated positive effect of Acadian® extract of Ascophyllum nodosum on plant stress-resistance, however the mode of action is not fully understood. The aim of this study was to understand the physiological effect of Acadian® seaweed extract on the plant response to drought stress. Leaf temperature and leaf angle were measured as […]
Root growth of containerized lodgepole pine seedlings in response to Ascophyllum nodosum extract application during nursery culture
Abstract Vigorous root growth immediately after spring planting is crucial to ensure a well-developed root system before the occurrence of drought events associated with climate change. The objective of this study was to enhance spring root growth of containerized lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) seedlings. Seedling culture began in April. In September, […]
Applications of a Commercial Extract of the Brown Seaweed Ascophyllum nodosum Increases Drought Tolerance in Container-grown ‘Hamlin’ Sweet Orange Nursery Trees
Abstract Hamlin’ sweet orange trees on ‘Carrizo’ citrange and ‘Swingle’ citrumelo rootstocks were treated weekly with a commercial extract of the brown seaweed Ascophyllum nodosum at 5 and 10 mL·L−1 as either a soil drench or foliar spray. Half of the trees in each treatment were subjected to drought stress [irrigated at 50% of evapotranspiration […]
Ascophyllum extract application can promote plant growth and root yield in carrot associated with increased root-zone soil microbial activity
Abstract Root growth and soil microbial activity were examined in two cultivars of carrot following treatment with Ascophyllum nodosum marine-plant extract. Field experiments were established in grower-managed fields of Maverick and Pronto carrots during 2010 and 2011. Soluble Ascophyllum extract powder (SAEP) was applied weekly, bi-weekly or tri-weekly at rates of 0 (control), 0.25, 0.50, […]
Commercial extract of the brown seaweed Ascophyllum nodosum enhances phenolic antioxidant content of spinach (Spinacia oleracea L.) which protects Caenorhabditis elegans against oxidative and thermal stress
Abstract There is considerable interest to enhance the nutritional quality of fresh produce especially vegetables. The effects of root treatment of spinach with commercial extracts of the brown macro alga, Ascophyllum nodosum (ANE) on antioxidant level of spinach were studied. At the concentration of 1.0 g/L, ANE treatment significantly increased the total phenolics and flavonoids […]
Effect of Ascophyllum extract application on plant growth, fruit yield and soil microbial communities of strawberry
Abstract Plant growth and associated soil microbials were examined in several strawberry cultivars following treatment with extracts from the marine algae Ascophyllum nodosum [soluble Ascophyllum extract powder (SAEP)]. Greenhouse and field experiments were established over plots of Albion, Camarosa, Chandler, and Festival strawberries from 2009 to 2011. Soluble Ascophyllum extract powder was applied once or […]
Effects of Ascophyllum nodosum extract application in the nursery on root growth of containerized white spruce seedlings
Abstract In this preliminary study, Picea glauca seedlings were root drenched with a commercial liquid extract of Ascophyllum nodosum in finisher fertilizer (8N–20P–30K) at the following rates: 1:500, 1:250, 1:125, and 1:75. Fertilizer alone served as control. Applications were made four or eight times over a period of 17 or 43 days, respectively. Compared with […]
