Functional differences between various types of soil testing instruments

Soil testing and formula fertilization is based on the laws of crop manure requirements, soil nutrient performance and fertilizer effects. Based on the rational application of organic fertilizers, the application quantities of nitrogen, phosphorus, potassium, and medium and trace elements, fertilizer application period, and application methods are proposed. . Another common point is that crops lack what's missing. In order to understand nutrients in crop soils, it is possible to use soil testing and formula fertilization instruments to perform operations. However, soil testing and formulating fertilizer applicators can also be replaced by the following instruments. What are the differences between alternative instruments?

Instrument name and model

Soil Tester TPY-6

Soil NPK Analyzer TPY-6A

Soil testing formula Fertilizer meter TPY-6PC

Fertilizer Speed ​​Tester TPY-6G

Soil Tester TPY-IV

Near-infrared soil analyzer TOP-4000

Functional differences

Measurable indicators: available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter content, soil pH, and soil salinity (quantitative), with storage, printing

In addition to having all the functions of the TPY-6 model, the nutrient components required for the growth and development of 70 kinds of crops are stored in the instrument instead of the fertilizer formulation software. The amount of fertilizer can be output according to the user's needs and printed out.

In addition to having all the functions of the TPY-6A model, soil moisture can also be measured. The equipment is equipped with the “Intelligent Formula Fertilization Software System” CD-ROM, which can guide the amount of fertilizer to be output according to the user's needs. The nutrients required for growth and development of 70 kinds of crops are stored; Equipped with a micro-printer outside. It can also be stored by the computer for data storage, remote transmission, and printing.

It can quickly determine the content of active components of N, P and K in various chemical fertilizers and the residual contents of heavy metals such as lead and chloride. Built-in shape printer, can upload the measurement result to the computer at the same time

Measurable indicators: Available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter content in plant, with formula function, can be used to instruct fertilizing amount according to user's demand, without printing function

The soil sample can be directly put into the sample chamber to measure the content of N, P, K, organic matter, water, etc. in the soil, and the nutrient curve of the test nut can be drawn automatically, and the printing function is provided.

These six kinds of soil measuring instruments can measure the contents of their own measurements in different regions and fields. Therefore, when selecting a soil testing and fertilizer application instrument, you must first understand the key points you want to measure in accordance with the above table. To make a choice.
