Foliar Fertilizer叶面肥料

Key points

• The advantages are rapid response and small doses, making it suitable for correcting deficiencies in the middle and late growth stages; the limitation is that a single application supplies little, so it cannot replace soil application.
• Concentration and timing are critical: too strong a solution scorches the leaf, and spraying in high temperature and bright sunshine worsens both scorching and evaporative loss.
• Urea and monopotassium phosphate are common ingredients — for example 0.3% urea with 0.3% monopotassium phosphate at grain filling in wheat.
• Compatibility must be checked before tank-mixing with pesticides to avoid precipitation or aggravated phytotoxicity.
