Nitrogen starvation

英语百科

Nitrogen deficiency

A young cabbage plant exhibiting nitrogen deficiency.
By measuring chlorophyll content Nitrogen deficiency can be detected.

All plants require sufficient supplies of macronutrients for healthy growth, and nitrogen (N) is a nutrient that is commonly in limited supply. Nitrogen deficiency in plants can occur when organic matter with high carbon content, such as sawdust, is added to soil. Soil organisms use any nitrogen to break down carbon sources, making N unavailable to plants. This is known as "robbing" the soil of nitrogen. All vegetables apart from nitrogen fixing legumes are prone to this disorder.
