Managing Soil Nutrients for Cinnamon Cultivation
To ensure plant roots effectively absorb soil nutrients, it’s crucial to preserve soil moisture using conservation methods, maintain optimal soil acidity, and promote beneficial soil microorganisms through proper soil management practices. Dolomite is utilized to regulate soil acidity, and fertilization should be performed at least six weeks after dolomite application.
Integrated plant nutrient management is also essential, combining half (50 g) of the recommended inorganic fertilizer mixture annually with one kilogram of compost manure per cinnamon bush, ideal for its perennial nature.
