1) the fertilizers mixed in water and applied to the base of the fruit plant
2) fertilizer nutrients applied through drip irrigation (FERTIGATION)
Q: In which scenario, nutrients will be faster available to the roots of the fruit crops?
What’s the difference between fertigation and hand applying fertilizers to fruits in terms of nutrients uptake and availability ?
Normally, Fertilizer is in the form of Power which is applied around the surface of the plant. But, under drip method of irrigation, Fertilizer is in the form of liquid which is mixed with the water and applied through the drip lateral with irrigation water.
The use of venture applications work best in a greenhouse operation but this demands a sizable capital cost which restricts the economics to high value horticultural crops in many instances.
Because of the need to grow our food more intensively based on shrinking arable land and ever increasing populations the use of the intensive fertigation systems and vertical farming with increase but it will likely cause prices to increase for the consuming public also.
In fertigation systems obviously nutrients are applied fully dissolved in water and in immediate proximity to the root system of the plant. Therefore they are and remain also fully plant available. Another advantage of fertigation is that you can adapt the nutrient composition and nutrient ratios to the specific demand of different crop growth stages. “Hand application” has limited frequency, may lead to nutrient fixation in the soil depending on fertilizer source and may be much less adapted to the varying nutrient needs during plant development.
The fustigation simply is a process that combines fertilization and irrigation. Fertilizer is added into an irrigation system. It is most commonly used by commercial growers. Fustigation is the type of fertilization in which fertilizers are applied through an irrigation system directly to the plant roots. In fustigation, either water-soluble or liquid fertilizers can be used. When choosing a proper fertilizer, crop growth stages should be considered, as well as irrigation system type and water quality.
But in Hand applying it is the old procedure some places is applied more some places less not uniform depends upon farmer experience, more losses.
