? Cassiopeiae has an unusual spectrum that has anomalously weak nitrogen lines, taken as an actual nitrogen deficiency in the atmosphere.
12.
Other symptoms of a nitrogen deficiency are premature leaf drop, smaller leaves and / or stunted and a slower overall mgrowth rate.

14.
Because of the link between chlorophyll content and nitrogen content in leaves, chlorophyll fluorometers can be used to detect nitrogen deficiency in plants, by several methods.
15.
Iro " et al . ", trying to interpret the nitrogen deficiency in comets, stated most of the conditions for hydrate formation in the protoplanets feeding zones.
16.
S . pombe is normally a haploid cell but, when put under stressful conditions, usually nitrogen deficiency, two cells will conjugate to form a diploid that later form four spores within a tetrad ascus.
17.
Nitrogen deficiency can be prevented in the short term by using grass mowings as a mulch, or foliar feeding with manure, and in the longer term by building up levels of organic matter in the soil.
18.
Other symptoms of a nitrogen deficiency are premature leaf drop, smaller leaves and / or silized lawns result in heavy blade growth and a weakened root system, leading to reduced drought and disease / pest tolerance.
19.
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.
20.
These species are rated as intermediate in nitrogen deficiency tolerance and consequently are able to grow with lower levels of nitrogen than are required by " nitrogen-demanding " white ash ( " Fraxinus americana " ), yellow-poplar ( " Liriodendron tulipifera " ), and American basswood ( " Tilia americana " ).
