Ohio State University research found that coffee grounds contain about 2% nitrogen, which can convert organic matter into fertilizer, which is a safe and environmentally friendly fertilizer. Huang Yu-ming, an associate professor in the Department of Soil and Environmental Sciences at Chung Hsing University in Taiwan, points out that coffee grounds, whether dry or wet, can provide nutrients for plants as long as they are spread out on the top layer of soil and allowed to decompose on their own. However, it is not recommended for growing large quantities of crops.
In addition, because coffee grounds contain alkaloids, they can be used as natural pesticides. First, coffee grounds are ground and dried, and then boiled again with water. After the boiled coffee water is cooled, it is placed in a spray bottle and sprayed on the place where there are insects on the plant. It has the effect of insect repellent. It can be sprayed once every two or three days.
