Cách cải tạo đất phèn hiệu quả và rẻ tiền nhất!!!

Hello everyone, welcome to Vung Huu Co channel Today I'm going to share with you how to renovate the rooftop Let's get started This is yellow soil, also known as sour soil This soil has low pH, it's about 5.5 Sometimes it's low, only 3 or 2 The cause of yellowing is iron and aluminum ions You can see the yellowing through the water There is a reddish-orange color, it's iron If the water is clear, but there is no grass on the shore, it's aluminum Yellow soil has low pH, low calcium It affects the growth of the plant, making the plant slow to grow I watered the plant 4 times, and the plant grew very slowly These are the outside effects of yellowing To know if there is yellowing in your garden I will show you a tool to check the yellow soil It's a paper It's sold in medical equipment stores It's a pH meter As I said before, the pH of yellow soil is 5.5 5.5 is yellow 6 is green 7 is green 5.5 is sour soil The ideal pH for the plant to grow well is from 6 to 7 From yellow to green Now I will use these 3 paper to test the pH of the soil To do this experiment, first I take a small sample of soil I put it in a small bowl like this I pour water in and stir it up I wait for the soil to settle down I will use the remaining water to experiment I will start right away I will wet this paper After the paper is wet, it has an orange-yellow color Let's see if it matches the pH of the soil It matches the color number 4 Look carefully The color number 4 is smaller than 5.5 So I can conclude that this soil is yellow soil It is also called sour soil with a pH of 4 When we have determined that the soil in our garden belongs to yellow soil We have to start cultivating yellow soil Soil is one of the cheapest and most popular solutions to get rid of yellow soil This is soil powder You can buy it at agricultural stores It is also cheap, about 5,000 to 7,000 VND for 1 kg of soil To get rid of yellow soil, we have to dig up the soil And water the soil to get rid of yellow soil This is the most effective way to get rid of yellow soil on sunny days Avoid doing it on rainy days Because when the soil is wet, it cannot absorb more water to get rid of yellow soil Then I mix the water I mix 2 kg of water and 100 liters of water For my small garden, I don't need to follow the exact ratio I can measure it I mix the water and I see that the water has a milky white color The water has been mixed Now I will water the soil I water the soil where I dug up Early in the morning, I will water the soil After that, I dry the soil in the sun all day The next day, I continue to water the soil in the morning I dry the soil in the sun all day And I do it continuously for 3-4 days This is yellow soil with pH level 4 After 4 days of continuous watering in the sun I don't know how the pH level has changed Now I will check the pH level This bowl of soil was taken from the place where the soil was watered Now I will use a piece of paper to check the pH level The paper is yellow Yellow does not fall to orange But it doesn't fall to blue According to this pH chart, I can see that the pH level is 5 Let's take a closer look Great From the soil with pH level 4 After 4 days of continuous watering in the sun Now I check the pH level again The result is 5 It can be said that watering is one of the most effective solutions for yellowing This is a great result When watering in the ground, the tree has the condition to develop rapidly Nutrition becomes easier to absorb Fewer diseases Since then, the health of the tree gradually recovers The soil in my garden has reached pH level 5 I will continue to water to increase the pH level from 6 to 7 And of course, in order to reach this level In addition to watering in the ground, I have to fertilize the soil I just finished sharing how to cultivate the soil Thank you for watching the video Wish you success See you later If you like my garden, please click like, subscribe to subscribe to my channel and watch the next videos
