How to analyze soil fertility:

Fertile soil is a necessary condition for a good crop harvest. Animal and plant residues contain a large amount of organic matter and humus in the soil. The fertile soil has a good structure, the soil quality is neither loose, nor sticky, has good water permeability, and its pH value is suitable for plant growth, and it is rich in a large number of elements (nitrogen, phosphorus, potassium) and micronutrient elements (boron) required for plant growth. , Copper, iron, sulfur, magnesium, molybdenum, etc.).

• 1. First remove the topsoil about 5 cm; then mash the soil down to a depth of 13 cm. And clean up all organic impurities in the soil that will affect the test results, such as leaves, roots, etc.
• 2. Soak the soil with water and mix thoroughly to form a muddy shape. (Use rainwater or distilled water).
• 3. Wipe the probe clean with a clean cotton or paper towel.
• 4. Move the function key to the first gear from the left.
• 5. Insert the probe into the tested soil until the distance between the soil and the body does not exceed 2.5 cm. Wait no more than 10 seconds, and the data can be read after the pointer is stable.
• 6. Record the data. Remove the probe from the soil and clean the probe thoroughly.
• 7. If you need to continue to analyze other soils, please repeat the above steps.

Result analysis:

"Too little" means you need to spread fertilizer

• 1. The fertilizers dissolved in water, then water combined with added nutrients to crops;
• 2. Plant or transplanting plant watering should be combined with three weeks after fertilization, and each month when watering plants do.

"Ideal" means ok.

• Combining with the watering, fertilizing once a month

"Too much" means no need fertilizer currently.

• Just watering;
• You will plant to transplanting to the new soil;
• For the plants in the greenhouse, should be a lot of water, dilute nutrient leaching too much;
• Don't let any chemical fertilizer, but can be applied into the manure, compost, plant residues, etc.

Precautions:

• If the soil is too dry before testing, please moisten the soil with water first, hard insertion will damage the electrode tip!
• When using for the first time, insert the probe in the soil several times to remove the oil and impurities. When measuring the pH and humidity of the soil, first insert the probe into the soil as deep as possible, and read the pH value after about 10 minutes. When the soil at the point is too dry or too fertile to measure the pH of the soil, you must first splash water on the measuring point and wait for 28 minutes before measuring.
• When using it, make sure that the probe cannot be inserted into the stone. Do not use excessive force, otherwise the probe may be easily damaged. After use, clean the probe with water and dry it with a cloth for storage.
• Please do not insert the probe into the soil for a long time, and do not use this device to test liquids, so as not to damage it.
• This product only tests dirt and soil, etc. It is not suitable for liquid, dry flour, small stones, organic wood chips, etc.
• This product is suitable for detecting nutrient soils, and the detected values ​​are relatively accurate. For soils with low density or too muddy, such as sandy soil and red soil, the meter needle may not move due to the poor conductivity of the soil. You can change the detection environment to re-test. .
