Divided into acidic and alkaline soils, in fact, fertilizer, too. But many farmers and fertilizer, only interested in nutrient content and ratio of nitrogen, phosphorus and potassium, leading to poor fertilization effect. Fertilizer physiological pH and chemical acid alkaline pH can be divided into two. Ammonium sulfate, calcium superphosphate and other soluble in acidic in water or weak acid, ammonia, potassium carbonate dissolved in water is alkaline or alkaline, urea, potassium sulfate, calcium nitrate soluble in water is neutral, so belonging to chemical acid/base/neutral fertilizer. Ammonium bicarbonate, urea, and after the fertilizer into the soil by plant uptake and use, the soil is neutral or close to neutral, so belonging to the physiological neutral fertilizer.

Soil pH can affect the dissolution and precipitation of nutrients in the soil, and can affect microbial activity, indirectly affect the availability of soil nutrients. Must use alkaline or acidic soil physiological alkalescent fertilizer, such as ammonia, calcium magnesium phosphate and calcium nitrate and in alkaline soils, suitable for application of superphosphate, ammonium sulphate, ammonium chloride and other acidic and physiological acid fertilizer.
