Excessive fertilization costs a lot. If you don't look, you lose a lot.

Excessive application of chemical fertilizer is a common problem in agricultural production, and its adverse effects are becoming more and more obvious. if we do not pay attention to it and continue to develop, we will certainly pay a higher price! So what are the adverse consequences of excessive fertilization?

?

The harm of excessive fertilization:

1. Reduce crop yield and quality.

Excessive fertilization will have two effects on crops, one is that crops are dependent on fertilizers, and then their resistance to diseases and insect pests is weakened, so they can only use more chemical fertilizers and pesticides, forming a vicious circle. Second, crops are easy to lodge, which will directly affect grain production.

2. Aggravate the damage of soil environment.

Excessive fertilization will lead to soil consolidation, and residual a large number of insoluble and toxic substances, so that soil acidification or salinization is serious, pathogenic bacteria spread wantonly, seriously damage the soil environment, so that it is no longer suitable for the growth of crops.

3. Increase production cost

Excessive use of chemical fertilizer will greatly increase the cost of farmers' production, make them pay more manpower and material resources for production management, and get half the result with twice the effort, and the output and quality can not be significantly improved.

Ways to make rational use of chemical fertilizer:

1. Choose the appropriate formula.

In the process of fertilization, the formula should be selected scientifically, and the formula should be optimized at any time according to the change of production conditions.

2. Increase the application of organic fertilizer reasonably

The mature farm manure and finished organic fertilizer have comprehensive nutrients and long-lasting fertilizer effect, which can effectively increase the content of organic matter in the soil, fertilize the soil, promote the reproduction of soil microorganisms, and improve the utilization rate of fertilizer, which is very beneficial to improve the quality of crops.

3. Attach importance to the application of microbial fertilizer.

The beneficial bacteria in microbial fertilizer can inhibit or kill the pathogenic bacteria in soil through their own physiological activities, and prevent the infection of soil-borne diseases to crops from the root.

The functional bacteria can also break the consolidated soil, degrade the harmful substances of chemical fertilizer and pesticide residues, activate the fixed phosphorus, potassium and other trace elements in the soil, make them absorbed and utilized by crops, improve crop quality and resistance at the same time, greatly reduce the use of chemical fertilizer.
