Leftovers as fertilizer

Leftover rice can be used as fertilizer. It contains starch, lipids, sugars and other substances that can supplement nutrients for plant growth. However, it cannot be poured directly into the soil because the carbohydrates in it can easily be used by microorganisms to breed bacteria and mold, causing damage to the plants. It must undergo fermentation before use.

Leftover rice can be used as fertilizer for most plants, such as azalea, peony, Clivia, green ivy, tiger skin plant, asparagus fern, spider plant, money tree, lucky bamboo, etc.

How to make fertilizer from leftover rice

1. Anaerobic fermentation method: Pour the leftover rice into a cement pool, then add ten times the volume of water, stir it evenly and let it ferment naturally.

During this period, pay attention to replenish the evaporated water in time.

Key points for using leftover rice fertilizer
