Farm manure sometimes there will be urine poured into the soil will become nutritious soil?

Will the soil become nutrient soil if urine is poured into the soil? Science Xingnong clearly tells you that the soil poured into urine in this way definitely does not belong to nutrient soil!

To clarify this problem, let's first understand what is called nutrient soil! According to the definition of encyclopedia, nutrient soil refers to bed soil containing a variety of minerals without pests and diseases that can meet plant growth and development. Let's see if the soil poured by urine meets the above definition!

The main component of urine is urea, which has a high nitrogen content. Of course, it also contains certain phosphorus and potassium elements. However, it should be noted that the nitrogen content in urine seems to be somewhat high. If urine is poured into the soil, it cannot satisfy the growth of plants. And it does not belong to man-made soil, which is different from the concept of nutrient soil we conventionally know.

In the selection of farm manure organic fertilizer, scientific agriculture repeatedly emphasized "decomposition", the reason for emphasizing this point is that the nitrogen content in the undecomposed farm manure is too large, which is easy to cause burning and death. After decomposition and fermentation, urea in the farm manure is degraded into ammonium nitrogen and transformed into nitrate nitrogen by microorganisms, which greatly reduces the possibility of seedling burning.

However, although the soil watered by urine cannot be called nutrient soil, it is undeniable that the soil contains high nutrients. As mentioned above, urine contains almost all the elements needed for plant growth and development. Studies have shown that when urine is diluted into soil, plants grow very well.

Scientists have used urine as fertilizer to fertilize tomatoes and found that tomatoes yield much higher than unfertilized tomatoes, and there is no difference in quality.

That is to say, although urine can be used as fertilizer, due to its high nutritional content, it seems that the plant is a little empty and not supplemented! Therefore, in agricultural production, urine is either spread into the field after decomposition, or when fertilizing, urine is kept away from plants to avoid "burning seedlings".

Here is science rejuvenates agriculture, welcome to add attention, take you to grow knowledge together.
