What are the uses of soil nutrient tester and how effective is it?

What does the soil nutrient tester do? Topyunnong's soil nutrient tester is a special soil testing instrument for rapid determination of soil nutrients. In recent years, due to the continuous aggravation of soil pollution, soil remediation has become the focus of our country's work. Therefore, soil testing is indispensable for soil remediation. For this reason, soil nutrient testers have been widely used in the market.

Soil nutrient testers are often used in cultivation and farming, and are mainly used to detect ammonium nitrogen, available phosphorus, effective potassium, organic matter, pH, salinity, etc. in soil and fertilizers.

The application of this instrument has alleviated the needs of farmers in various places for soil testing and fertilization formulation. At the same time, it also provides a reliable basis for fertilizer production enterprises to achieve specialization, systematization, informatization, and dataization. It is an instrument for soil testing and fertilization formulation in the agricultural sector. In addition, the instrument can measure soil nutrients in a short time, and the instrument has an integrated chassis, small size, light weight, easy to carry, and the instrument has a liquid display. It can be widely used in agricultural testing centers at all levels, agricultural research institutes, fertilizer production, agricultural materials management, agricultural technology services, planting bases and other fields.

The soil nutrient tester can quickly measure the nutrient content in the soil. Here we will introduce its rapid testing method.

The conventional analysis method of effective nutrients is simplified, such as reducing the volume of the leaching solution, shortening the leaching time, simplifying the leaching and determination steps, and using visual colorimetry, etc., so that the operation is quick and easy, the determination results have a certain degree of accuracy, and are easy for the public to grasp. Because the rapid test uses a relatively simple extraction method, some nutrients cannot be completely extracted, and the amount of nutrients measured is generally lower than that of conventional analysis. The workload of soil analysis lies in pre-treatment. To increase the determination speed, it is necessary to achieve rapid extraction of multiple nutrients at the same time. It can be said that the combined extraction technology is the basis of the rapid test method.

In recent years, the combined extractant, calcium chloride extractant and ASI combined extractant have been widely used in domestic research. This method is fast, can test a large number of samples, and can provide timely guidance for practice; however, the amount measured is lower than that of conventional methods.
