What Is Rice Water?
Rice water is the starchy liquid left after washing, soaking, or cooking rice. During this process, rice releases essential nutrients such as carbohydrates, amino acids, B vitamins, and small amounts of minerals like nitrogen, phosphorus, and potassium. These nutrients support beneficial microorganisms in the soil and improve plant health naturally.
Benefits of Rice Water for Plants
Rice water offers several advantages when used correctly:
- Promotes root growth by improving soil microbial activity
- Enhances leaf growth and overall plant vigor
- Improves soil fertility and structure
- Encourages beneficial bacteria and fungi in the soil
- Cost-effective and eco-friendly, using kitchen waste
- Suitable for indoor and outdoor plants
However, rice water should always be used in moderation to avoid sour smells or pest attraction.
