Most of them are absorbed from soil through roots, and the proportion is: 94%-99.5% of fresh tissues of crops are composed of hydrogen, oxygen and air, while only about 0.5%-6% are nutrients from soil.

Grape is similar to most crops, and its growth requires about 17 kinds of nutrients: carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, molybdenum, chlorine and diamond. Carbon and oxygen in bases come from carbon dioxide in the air during photosynthesis, while hydrogen comes from water in the soil.
