Microbial Fertilizer微生物肥料

Key points

• The core indicator is the count of viable micro-organisms, usually expressed in hundred-millions per gram or per millilitre. A failed microbial fertilizer is more often deficient in viable organisms than in nutrients.
• It cannot replace chemical fertilizer: it supplies functional micro-organisms rather than macronutrients.
• Shelf life is short and storage temperature and humidity directly affect survival, which is why expiry dates and storage conditions are normally declared on the package.
• It must not be applied together with fungicides or strongly acidic or alkaline materials, which would kill the functional organisms and nullify the product.
