The mutual growth and mutual restraint relationship between fertilizers!

There are so many elements needed by crops, there are "antagonism" and "synergy" among the elements.

Antagonism refers to the mutual restraint of two fertilizers, and simultaneous application will affect the absorption of each other.

The synergistic effect means that the two fertilizers complement each other, and the simultaneous application can promote the absorption of each other.

Mastering the relationship between various fertilizers and achieving scientific and reasonable fertilization can maximize the efficiency of fertilizer use.

The "antagonistic" and "synergistic" relationship between each element:

1. Nitrogen: Different forms of nitrogen have different absorption effects, and nitrate nitrogen is more difficult to absorb than ammonium nitrogen. At the same time, excess potassium and phosphorus will affect nitrogen absorption; boron deficiency is also not conducive to nitrogen absorption.

2. Phosphorus: Excessive nitrogen is not conducive to the absorption of phosphorus.

In addition, zinc and iron will also affect the absorption of phosphorus; lime will make phosphorus unavailable and cannot be absorbed. Magnesium aids in the absorption of phosphorus.

3. Potassium: Excessive nitrogen is not conducive to the absorption of potassium, and calcium, magnesium, and zinc will also affect the absorption of potassium. Boron is beneficial to the absorption of potassium.

4. Calcium: There are many elements that affect the absorption of calcium. Nitrogen, potassium, magnesium, boron, sulfur, manganese, etc. will all affect the absorption and transportation of calcium.

In addition, ammonium salt will affect the transfer of calcium to the fruit and reduce the absorption of calcium.

5. Magnesium: Excessive nitrogen will cause magnesium deficiency, too much potassium and phosphorus is not conducive to the absorption of magnesium; excessive application of sulfate fertilizers will also cause magnesium deficiency.

Magnesium and zinc have a synergistic effect, and magnesium deficiency can easily induce zinc and manganese deficiency.

6. Iron: Excessive nitrate nitrogen, phosphorus and calcium will cause iron deficiency, and boron will also affect the absorption of iron. Potassium can promote iron absorption, potassium deficiency may cause iron deficiency.

7. Boron: Boron and calcium are closely related physiologically. When the supply of calcium increases, plants need more boron

Nitrogen has a great influence on the absorption of boron, and when nitrogen increases, the absorption of boron by plants will decrease accordingly;

When boron supply is low, increasing potassium will aggravate boron deficiency, and when boron supply is high, increasing potassium will aggravate boron damage.

8. Manganese: Calcium, zinc, and iron will hinder the absorption of manganese, and the hydroxide of iron can make manganese appear in a precipitated state; applying physiologically alkaline fertilizers can fix manganese.

Sulfur and chlorine can increase the released and available manganese, which is beneficial to the absorption of manganese.

9. Organic fertilizer: We have always advocated increasing the application of organic fertilizer, because organic fertilizer can not only improve soil texture, but also have a balanced nutrient content, which can avoid the lack of medium and trace elements.

However, excessive application of organic fertilizer should not be done blindly, because when there is too much organic fertilizer, microorganisms in the soil will compete with crops for nitrogen, resulting in a temporary nitrogen deficiency in the soil for a period of time.

In addition, too much organic matter is easy to form complexes or chelates with zinc, thereby reducing the effectiveness of zinc.
