Summary:

In this article, you will learn how to use accurate, fast, and stable soil NPK sensor to measure soil nutrient content such as nitrogen, phosphorus, and potassium. The sensor is suitable for detecting the content of nitrogen, phosphorus and potassium in the soil, and judging the fertility of the soil by detecting the content of nitrogen, phosphorus and potassium in the soil, thereby facilitating the customer’s systematic assessment of the soil condition.

Application:

You know all growing plants need 17 essential elements to grow to their full genetic potential. Of these 17 elements, 14 are absorbed by plants through soil, while the remaining three come from air and water. Nitrogen, Phosphorus, and Potassium or in short NPK, are the “Big 3” primary nutrients in commercial fertilizers. Each of these fundamental nutrients plays a key role in plant nutrition. Nitrogen, Phosphorus, and Potassium are really important to soil because; Nitrogen is used by plants for lots of leaf growth and good green color, Phosphorus is used by plants to help form new roots, make seeds, fruits, and flowers, while Potassium helps plants make strong stems and keep growing fast. A certain level of Soil nutrients like Nitrogen, Phosphorus, and Potassium should be maintained in the soil which is only possible if you know how to measure these three elements.

Let’s take the corn plant as an example; this is what happens to the corn leaves when the nitrogen, phosphorus, and potassium nutrients are less in the soil.

On the other hand, if you add more nitrogen, your plants may look lush and green, but their ability to fruit and flower will be greatly reduced. If you add more phosphorus this will reduce the plant’s ability to take up required micronutrients, particularly iron and zinc this causes the plants to grow poorly and even die. The same thing happens when you add too much Potassium to the soil this disrupts the uptake of other important nutrients, such as calcium, nitrogen, and magnesium.

So, now you understand the excess and deficiency of these three elements is not good for the plants. So, before you are planning to add the fertilizer first take a few samples and check the Nitrogen, Phosphorus, and Potassium level using the Soil NPK Sensor.

After performing the initial tests and once satisfied with the values, then displayed the NPK values on the Android cell phone application.

You can also connect the display module, this way you can monitor the NPK values both on the display module and also on the Android cell Phone application.

Sensor Features：

(1)Convenient measurement: soil nitrogen, phosphorus and potassium detection is no longer limited to the industry, the instrument can be inserted into the soil to measure;

(2)Low cost: compared with the traditional laboratory measurement, (3)soil NPK sensor has the advantages of low threshold, low cost, less steps, no reagent and unlimited detection times;

High precision, high resolution: high precision, fast measurement speed, can reach 2% accuracy, increased stability. The resolution is as high as 1mg / kg (mg / L), and it is easy to carry，The data can be retrieved by inserting the soil, which shortens the time cost.
