Successful Cases
Farm Background
- Case Name: Case of 12% Seaweed Extract Fertilizer Improving Tomato Yield and Quality at Sunshine Farm
- Time: Planting season in 2022
- Person in Charge: [Name: Li Ming]
- Position: Agronomy Supervisor of Sunshine Farm
- [Sunshine Farm] is a commercial tomato – growing farm covering 50 acres in [Beijing]. The soil in this area was initially of medium fertility, with challenges in maintaining consistent moisture and nutrient availability for optimal tomato growth.
Application of 12% Seaweed Extract Fertilizer
- Soil Application: At the beginning of the planting season, the farm applied the 12% seaweed extract fertilizer at a rate of 1.5 liters per acre. The fertilizer was diluted with water at a ratio of 1:250. This diluted solution was evenly distributed across the soil surface using a tractor – mounted sprayer before transplanting the tomato seedlings.
- Foliar Spray: During the vegetative and flowering stages, a foliar spray was carried out. The 12% seaweed extract fertilizer was diluted at a ratio of 1:400 with water. Approximately 0.8 liters of the diluted solution was applied per 1000 square feet of tomato foliage area every 10 days.
Results
- Yield Increase: Compared to the previous season when a traditional fertilizer was used, the tomato yield increased by 25%. The average yield per acre rose from 30 tons to 37.5 tons. The increase was attributed to enhanced root development, which allowed the plants to access more nutrients and water from the soil. The seaweed extract also improved the plants’ resistance to stress, enabling them to better withstand temperature fluctuations and occasional drought conditions.
- Quality Enhancement: The tomatoes had a more intense color, better firmness, and a sweeter taste. The market price of the tomatoes increased by 15% due to their improved quality. The seaweed extract – treated tomatoes also had a longer shelf – life, reducing post – harvest losses.
Nursery Background
- Case Name: Case of 12% Seaweed Extract Fertilizer Promoting Rose Growth and Flowering at Starlight Horticultural Nursery
- Time: The whole year of 2023
- Person in Charge: [Name: Wang Li]
- Position: Technical Director of Starlight Horticultural Nursery
- [Starlight] specializes in cultivating roses for cut – flower production. The nursery has a controlled – environment greenhouse covering 10,000 square feet. Maintaining the health and beauty of the roses, especially in terms of flower size, color, and stem strength, is crucial for their market competitiveness.
Application of 12% Seaweed Extract Fertilizer
- Potted Plant Application: For potted roses, 8 ml of the 12% seaweed extract fertilizer was mixed with 1.5 liters of water for small – to – medium – sized pots (8 – 12 inches in diameter). This solution was used to water the roses once every two weeks.
- Greenhouse – wide Application: In the greenhouse, 2 liters of the 12% seaweed extract fertilizer per 100 square meters were diluted with water at a ratio of 1:300. This diluted solution was applied through an automated irrigation system once a month.
Results
- Growth Promotion: The roses treated with the seaweed extract fertilizer showed more vigorous growth. The stems were 20% longer and 15% thicker on average compared to those not treated with the seaweed – based fertilizer. The plants also had more abundant foliage, creating a fuller and more attractive appearance.
- Flowering Improvement: The number of flowers per plant increased by 30%. The flowers were larger, with a diameter increase of about 15%. The color of the roses was more vivid, and the fragrance was more intense. These improvements led to a 20% increase in the nursery’s revenue as the higher – quality roses commanded a better price in the cut – flower market.
Field Background
- Case Name: Case of 12% Seaweed Extract Fertilizer Enhancing Wheat Stress Resistance and Yield on Bountiful Plain
- Time: Planting cycle from 2021 – 2022
- Person in Charge: [Name: Zhang Feng]
- Position: Technical Advisor of Fengyuan Agricultural Cooperative
- A large – scale wheat – growing field in [Fengyuan] covers 500 acres. The area is prone to occasional pest attacks and waterlogging during the rainy season, which often affects wheat growth and yield.
Application of 12% Seaweed Extract Fertilizer
- Soil Drench: Prior to sowing, 2 liters of the 12% seaweed extract fertilizer per acre were diluted with water at a ratio of 1:200. This solution was used to drench the soil, ensuring that the nutrients penetrated deep into the root zone.
- Foliar Application during Growth Stages: During the tillering and heading stages, a foliar spray of the 12% seaweed extract fertilizer, diluted at a ratio of 1:350 with water, was applied. Approximately 1 liter of the diluted solution was used per 1000 square feet of wheat field area.
Results
- Resilience Against Stress: The wheat crops treated with the seaweed extract fertilizer showed increased resistance to pests. The incidence of aphid infestation was reduced by 40% compared to the control fields. Additionally, the plants were more resilient to waterlogging, with a faster recovery rate after the water receded.
- Yield Boost: The overall wheat yield increased by 22%. The improved root structure and enhanced nutrient uptake due to the seaweed extract contributed to better – filled grains and higher biomass production. The farmer’s profit margin increased significantly as a result of the increased yield and reduced need for pest control chemicals.
12% Seaweed Extract Fertilizer FAQ
- Soil application: For general garden soil or farmland, apply 1 – 2 liters of the 12% seaweed extract per acre. Dilute it with water at a ratio of 1:200 – 1:300 (seaweed extract : water).
- Foliar spray: Dilute the 12% seaweed extract with water at a ratio of 1:300 – 1:500. Apply 0.5 – 1 liter of the diluted solution per 1000 square feet of plant foliage area.
- Potted plants: For small – to – medium – sized potted plants (up to 12 inches in pot diameter), mix 5 – 10 ml of the 12% seaweed extract with 1 – 2 liters of water. For larger potted plants (12 – 24 inches in pot diameter), increase the amount to 10 – 15 ml and mix with 2 – 3 liters of water.
- Soil application: It can be applied once at the beginning of the planting season, and for longer – growing crops, a top – up application may be done mid – season.
- Foliar spray: Repeat every 7 – 14 days during the growing season, depending on the plant’s growth stage and nutrient requirements. For potted plants, water with the diluted solution once every 2 – 3 weeks.
