1. Rashin isasshen haske yana hana photosynthesis. Rashin isasshen haske a lokacin damina zai hana photosynthesis da kuma rage aikin tushen sa. Musamman ga ciyayi da ba su da taki sosai, zai shafi tarin carbohydrates na tsirrai kuma ya hana metabolism na nitrogen, wanda ke haifar da rawaya na ciyayi.
2. Takin zamani ba shi da daidaito. A lokacin da ake shafa takin nitrogen a kan ciyawa, wasu ciyawa suna yin rawaya saboda yawan takin nitrogen, wasu kuma suna yin rawaya saboda rashin amfani da takin nitrogen.
