Why the land is more fertile after the flood

The reason why the land is more fertile after the flood is mainly because the flood brings a lot of nutrients and organic matter.

1.Nutrients such as nitrogen, phosphorus, potassium, etc., brought by floods, are very important for plant growth. These nutrients can be dissolved into floodwaters from the natural environment or carried to floodplains along with the soil and other material that has flowed down from the flood.

These nutrients can promote the growth and reproduction of plants, making the land more fertile after floods.

2.Organic matter, such as humus and microorganisms, brought by flooding, can also provide a good environment for plants to grow. These organic matter can improve the structure and texture of the soil, increase the aeration and water retention of the soil, and thus promote the growth and reproduction of plants.

As a result, after the flood, the land is more fertile and more conducive to plant growth.

While floods pose a threat to human life and property, they can also replenish water in wetlands, fisheries and irrigation systems. And the flood plains have great potential for development: their proximity to rivers ensures fertile soils, abundant water** and well-developed transportation.

In some areas, such as the Nile Valley, annual flooding is welcome because it rehydrates the land. But floodplain buildings and farms inevitably increase the risk of flooding. As the population of these regions continues to grow, they also attract the attention of experts, policymakers and the general public from different disciplines.

Relief and aid organizations, which monitor and mitigate flood hazards, are also keeping an eye on developments in these areas. When the flood comes, a large amount of nutrient-rich substances such as fish and shrimp and their feces are brought to the flooded area, and when the flood waters recede, these nutrients are left there. 2

If there is still water in the flooded land, drain it out first and dig deep into the ridges.

Dig a few more drainage ditches in the side drainage ditch and the ground, and make a few more drainage outlets for drainage in places that are conducive to drainage; There is no water in the ground, but the ground is dirty, so you can sprinkle water first after the flood and locusts.

When the pests suddenly had no way to live, they all drowned. The rice, wheat, and beans grown in this way do not even need to be sprayed with pesticides, but the yield is excessively high.

<> if it is a major flood and it lasts for a long time, it will have to find another way to solve it; The land is good for growing crops, and there are no pests, but there is a possibility: there are more rodents! Because the flood can drown everything else, but it is difficult for rodents to drown the flooded land, and there are some similarities between the flooded land and the new soil we dug up, after a flood, the upstream sediment is often silted up to the banks, mixed with grass blades and dead wood.

or growing plants and trees, which are also buried together with the sediment to form a new soil layer.

The flooded areas of the valley have become very fertile, and the seasonal floods have brought a lot of nutrients and water to these areas, so that the harvest in the coming year is much higher than in the year when there is no water, and we have the saying "one water and one wheat", which means that the fertilizer, including the cooked layer of the soil (the cultivated layer), is carried away with the water. After the flood of this kind of plot, after the sunny day is cool, when it can be deeply cultivated, it is necessary to reapply farm fertilizer such as chickens, ducks, pigs and sheep manure before cultivating the land, 30 cubic meters per mu, and spread evenly.

Another situation is that some land that is prone to flooding, most of which is low-lying, and whenever there is a flood, it must still be submerged, in other words, it is a disguised waterway, and even if such land is planted with crops, there is no guarantee that there will be a harvest. It's summer again, and most of it rots in the ground, making it the best fertilizer for the next year, and the soil is much softer. After freezing in winter, bacteria and pests are frozen to death, and the soil for spring cultivation is loose and delicate, and the first fertilizer is also omitted.

Because the land washed by the flood washed away all the nutrients on the surface of the land, and also brought a lot of silt, so you can't plant directly, you need to expose the land to the sun, clean up the debris inside, and then apply some fertilizer, so that you can plant.

Because this kind of soil is prone to rot in the roots, and it is also easy to lack oxygen in the roots. Be sure to fertilize the soil more so that you can increase the fertility of the soil.

Because the soil at this time is very bad, and there are no nutrients in the soil. We can fertilize the land in a cyclical and gradual manner.

When floods occur, they are unavoidable, so you should protect yourself instead of thinking about the loss of crops. At present, the relevant departments also provide a certain amount of compensation for the losses suffered by the peasants in the event of floods. So farmers don't have to worry about what to do when the floods recede.

As long as the soil is successfully treated, it is ready to be cultivated. But when floods occur, farmers are still in a bad mood.

I think the impact is very big because floods contain a lot of toxic substances and bacteria, which can seriously affect the soil quality.

Farming should not be carried out immediately after the accumulation of floodwaters, but after a period of time, so that the fertility of the soil will continue to accumulate.
