How to detect soil nutrients? We can use the instrument of soil nutrient fastness tester to analyze. The amount of nutrient content is very important for plant growth. Through the analysis of soil nutrients, we can determine the optimal growth environment of the plant to achieve the increase in production increment. Purpose.
How do you determine the indicators of soil nutrient deficiency? The indicator of soil nutrient abundance is an expression of the correlation between the measured values ​​of soil nutrients and crop yield. To determine the abundance of certain nutrient content in soil, it is necessary to conduct multiple experiments on the soil in different fertility levels in the all-fertilizer zone (for which the nutrient is applied) and for the lack of nutrients (without applying such nutrients). After determining the available nutrient content of each soil sample, and obtaining the paired yields in the entire fertilizer area and the lack of nutrients, the relative nutrient quantity was determined by the relative amount of production. According to China's proposed standards, the soil content below 50% relative output is “extremely scarceâ€, 50%-70% is “lackâ€, 70%-90% is “mediumâ€, and 90% is “rich†"The indicator of soil nutrient abundance. However, when it reaches abundance, we do not need to apply this nutrient fertilizer. Therefore, the measurement of soil nutrient content plays a crucial role.
There are many instruments on the market that can measure soil nutrient content: soil-testing and fertilizer-applying instruments, near-infrared soil nutrient analyzers, soil nutrient fastness testers, and soil testers. In addition to the near-infrared soil nutrient tester, the other three are the same product, just different names. Of course, this product has different models, corresponding to different functions, different models, the price will be a small difference. At present, the price of soil testing equipment ranges from 1000 to 19,000. Different users can choose according to their own needs. For additional products that need to be added, the cost is not too long. The life of the instrument is also relatively long. Under normal circumstances, it can be used for 10 years. Wait.
There is still room for development potential of the soil nutrient fastness tester, and the instrument has high measurement speed efficiency. A sample needs about 40 minutes, which is much faster than the same type of instrument, and the accuracy is high, and it is aimed at soil nutrients. Measure and fertilize the soil in a targeted manner to improve land utilization.
