If urine is poured into the soil, will the soil become nutrient soil? Science Xingnong tells you clearly that soil with urine poured into it is definitely not nutrient soil!

To sort out this question, let us first understand what nutrient soil is! According to the encyclopedia definition, nutrient soil refers to a prepared bed soil that can meet the needs of plant growth and development and contains a variety of minerals and no pests or diseases. Let us see whether soil with urine poured into it meets the above definition!

The main component of urine is urea, which has a very high nitrogen content, and of course also contains certain phosphorus and potassium elements, but it should be noted that the nitrogen content in urine seems somewhat too high. If urine is poured into the soil, it cannot meet the needs of plant growth. It is also not an artificially prepared soil, and in this respect it is different from the concept of nutrient soil as we conventionally understand it.

When choosing farmyard manure and organic fertilizer, Science Xingnong repeatedly emphasizes "decomposition," and the reason for emphasizing this is that undecomposed farmyard manure contains too much nitrogen, which easily causes seedling burn and death. After decomposition and fermentation, the urea in farmyard manure is degraded into ammonium nitrogen and converted by microorganisms into nitrate nitrogen, which greatly reduces the possibility of seedling burn.

However, although we cannot call soil with urine poured into it nutrient soil, it cannot be denied that this soil contains very high nutrient elements. As we also mentioned above, urine contains almost all the various elements needed for plant growth and development. Studies have shown that when urine is diluted and added to soil, plants grow very well.

Scientists once used urine as fertilizer for tomatoes and found that the yield of tomatoes was far higher than that of tomatoes without fertilizer, and there was no difference in quality.

That is to say, although urine can be used as fertilizer, because its nutrient content is too high, the plants appear somewhat too weak to absorb such rich nourishment! Therefore, in agricultural production, urine should either be spread into the field after decomposition, or when fertilizing, the urine should be kept away from the plants to avoid "seedling burn."

This is Science Xingnong. You are welcome to follow, and let us grow knowledge together.
