More fluid approach needed for plant nutrition

摘要

Targeting soluble nutrients by spraying or fertigation (nutrients dissolved in irrigation water) onto the foliage gives a more efficient and effective outcome. PLANT NUTRITION MIND-SET is still largely focussed at ground zero on the spread of solid fertiliser formulations over the soil. Crop plant root systems are still regarded as prime points for nutrient entry but more modern fluid thinking sees the most easily and effectively targeted plant parts as those above-ground.
