Tips for Strawberry Cultivation

• Any list of strawberry varieties will probably contain mostly the June-bearing type. June-bearers are the most popular varieties. They typically produce the largest strawberries, and do so over a period of two to three weeks, on average.
• A favorable microclimate for strawberries is an area with full sun at least six hours per day, uniform temperature, rainfall and drainage, and good protection from wind.
• Strawberries prefer slightly acidic soils with a pH of between 5.5 and 6.5. Too low pH values may require application of ground limestone to increase the pH of more acid soils.
• Strawberry plants are extremely sensitive to salinity, especially at the transplant stage.
• Irrigation is essential for high-yield strawberry production. Since the strawberry plants are shallow rooted, permanent moisture is necessary to maximize production. An average of 300 mm to 450 mm (12 to 18 inches) of irrigation water is required over the growing season.
• As strawberries grow they will produce runners that will spread out and root to produce additional plants. Position the first runners with approximately 15 cm (6 inches) spacing between them. Only allow a few runners per plant, then remove additional runners to promote crown growth.
• Intensively grown strawberries require frequent and precise fertility management. Leaf analyses provide the best means of monitoring nutritional status (deficiencies or excesses) and correcting deficiencies that may occur.
• Potassium is required by strawberry plants to help them acquire water through the roots and control water loss by transpiration. Potassium may compete with magnesium for uptake by the roots and must, therefore, be maintained at an appropriate ratio (4:1, K:Mg) in the soil solution to prevent one of these nutrients from overriding the other, thereby creating a deficiency.

Mixing Nozzle

Description : a mixing nozzle made of plastic polypropylene, resistant to fertilizer mixing environments, similar in shape and performance to a static Venturi unit.

The operating principle: the eductor connects by simply screwing it to the coupler of the water hose while filling the fertilizer tank. The special construction of the eductor (based on the Bernoulli principal) converts pressure into velocity, increases the exit velocity of the flow, leading to a better solution mix. Recommended sizes: threading of 1/4", 3/8", 3/4", 1 1/2".

User tips : the eductor is a simple and permanent installation that actively assists in the fertilizer dissolving process as soon as water begins filling the tank, and in some other units, even up to the point when dissolving is complete. A rigid hose is recommended for installation, and it should be placed as close as possible to the bottom of the fertilizer tank in order to make the dissolving process more efficient.
