On Ammonium Acetate Extraction Method
The good governance of the soil in ancient times, in the determination of its nutrients, the precision of the constant weight method. Today there is an ammonium acetate extraction method, which is the important way to test all elements in the soil.

This ammonium acetate extraction method must abide by the procedures when it is performed. Prepare utensils first, clean and clean, to prevent impurities from disturbing them. Take soil samples, the amount is moderate, and put them in special utensils. Then inject ammonium acetate solution, the concentration and dosage are fixed, and vary according to soil properties and measurement items. Stir well and let it sit until it is ready, so that the nutrients in the soil and ammonium acetate are fully mixed and dissolved in the liquid.

The reason for the heavy ammonium acetate extraction method is because of its effectiveness. In the measurement of exchangeable cations, it can accurately traffic acquisition, showing the soil's fertility retention and fertilizer supply. Such as potassium, calcium, magnesium ions, mentioned by this method, can show the amount of their exchange state in the soil, help farmers know the soil strength, to determine the fertilization policy. And in the detection of trace elements in the soil, it is also effective. The genera of iron, manganese, zinc, copper are observed, providing evidence for soil improvement and planting.

In addition, this method is convenient and efficient. Compared with other methods, it takes less time and results quickly. Although the essence of the instrument and the purity of the reagent are essential, it can be obtained by skilled operation. And its reproducibility is good, different at the same time, the ground survey is the same as the soil, the results are similar, which increases the reliability of the data.

The soil is the foundation of the observation of the farmer's mulberry. Ammonium acetate extraction method is very powerful in recognizing soil properties and improving fertility. If it is used well, the soil strength can be guaranteed and the property can be abundant, which is actually an important method related to people's livelihood.
