Functions of Essential Nutrient Elements in Garlic and Detailed Explanation of Deficiency Symptoms
Garlic prefers loose soil rich in humus, has strong adaptability to soil pH, and grows well under slightly alkaline conditions. Among the different growth stages of garlic, the demand for nitrogen is the highest, followed by potassium, calcium, phosphorus, and magnesium. For every 1000 kg of fresh garlic produced, it needs to absorb 4.5-5.0 kg of nitrogen, 1.1-1.3 kg of phosphorus, and 4.1-4.7 kg of potassium, with a ratio of about 1:0.25-0.9. The root system of garlic is a string-like fleshy root system, mainly distributed within the 5-25 cm plow layer, and it belongs to shallow-rooted vegetables.
