Is the compound fertilizer alkaline?
Sodium nitrate and calcium nitrate, the two kinds of nitrogen fertilizer is different. They are applied to the soil, because the crop absorbs the number of nitrate ions than sodium or calcium ions, can make the soil reaction was alkaline or weak alkaline, so sodium nitrate and calcium nitrate are physiological alkaline fertilizer.
As the crop absorbs the chemical nitrogen fertilizer in the yin, the number of cations is not equal, when the absorption of cations more than anions, can make the soil acidification fertilizer called physiological acid fertilizer.
Compound fertilizer is divided into physiological acid fertilizer and physiological alkaline fertilizer.
