i mean it's expected... afterall godgiven, the most fertile lands on the planet.

Contrary to what we love to believe, Bangladesh soil is not fertile. It has deficiencies in many organic substances requiring the infusion of inorganic fertilizer in all the crops.i mean it's expected... after all god given, the most fertile lands on the planet.
bro fertility doesn't necessarily guarranty enriched mineral contents for things to grow but ability to grow almost any kind of agricultural products...Contrary to what we love to believe, Bangladesh soil is not fertile.

- The average pH of Bangladesh soils could be taken on the acidic side of the pH scale, between 5.5 and 6.5. This value is good.
- Organic matter (OM) status of Bangladesh soil is one of the lowest in the world. This is a major constraint to the agriculture of the country.
- Because of the low level of OM the nitrogen status of Bangladesh soils is substantially low requiring the use of nitrogen fertilisers. Urea is based on nitrogen.
- The available phosphorus in Bangladesh soils could be considered between low and medium. The source of P supply in soils is mainly inorganic fertilizers and to a limited extent organic manure.
- Bangladesh soils are deficient in potassium.
- About 70-80% of the soils are deficient in sulphur.
- The demand for zinc fertilizers has been increased from 3 thousand metric tons in 2000-01 to 42 thousand metric tons in 2010-11, which indicates a widespread zinc deficiency in the soils of Bangladesh.
I hope the country's land does not get barren with the continuous use of inorganic/chemical fertilizers and three crops. Raise only two crops to extend the longevity of the land. Depend less on inorganic chemicals and more on organic cow manure and rotten paddy stalks (খ্যার). Keep the lands fallow for one season. Overturn the soil with a tractor in order to expose the soil bottom to sunrays. It will bring back the strength.
Bold part: Yours is a unique definition of soil fertility. Perhaps you are comparing BD land with the desert land of Arabistan. However, I have seen how the leaves of spinach (পুঁই শাক) grow large in the Libyan desert without fertilizer but with only the input of water. The sizes are more than double what we see in BD. It means the deserts have a lot of organic matters comparing to BD soils except that water is scarce there.bro fertility doesn't necessarily guarranty enriched mineral contents for things to grow but ability to grow almost any kind of agricultural products...
oh btw wasn't bangladesh facing problems in the 2005s because they would over grow GMO products on a given piece of land? i remember farmers being trained on efficient use of farmland and it's recovery

BD soils are not fertile but are enriched with water. The deficiencies of the Organic Matters (OM) are covered by chemical fertilizers. But, the future may be bleak unless chemicals are almost substituted with organic cow dung, rotten straws, and the soils are kept overturned for at least one season.
While harvesting, the Japanese (Korean, Taiwanese) farmers cut down only the upper paddy sheaves and leave the 90% of straws in the soil overturned by only a single run of the tractor. The straws gradually rot to become organic fertilizer that lessens the uses of chemicals.
Like many other things, BD has to learn from other countries that have developed agriculture through a concerted effort of more than a century.
Natural fertile soil may be very rare nowadays because of its overuse through centuries of intensive cultivation. It is more so now because of the need to produce more to feed a growing number of the population throughout the world. It seems Europe uses less amount of chemicals than even Japan although the latter always try to return the organic matters by rotting the straws.Which areas soil has more organic matter bro? I mean organic matter And also sufficient water supply, do you know that? I am interested to know about various soil with that is naturally fertile, but I found no clear information when search Google. If you know please provide some information.
Thanks brother for this informative post.Natural fertile soil may be very rare nowadays because of its overuse through centuries of intensive cultivation.

The US soil may be fertile but even they use a low quantity of fertilizer. However, please read the excerpt below to know about the bad effects of overuse of chemicals. It almost poisons the food. I was talking about the claim that BD soil is most fertile which I found is not true.
"One of the main differences between soil exposed to chronic use of chemical fertilizers and natural soil is the amount of microorganisms. Previously on farmland, organic matter such as fallen leaves and manure from animals was decomposed into non-organic matter by microorganisms in the soil, and using these natural fertilizers, agricultural produce could be grown".
"However, chemical fertilizers do not decompose, and are directly absorbed by plants—and without the food provided by organic matter, microorganisms die off. According to Kubo's research, ---------- in the farmlands where the number of microorganisms is close to zero, ---------, plant pathogens and pests breed easily, resulting in a vicious cycle in which more and more pesticide is needed".
1) So, limit the growth of the population
2) Limit crops to two seasons only
3) Use more organic matters in the straws/leaves that BD people mostly use for cooking. Re-use the rice/wheat straws by rotting them in the wet soil
4) Raise cattle farming and use more decomposed dung and fewer chemicals
By the way, I felt a bitter taste of BD vegetables when I am there. You are so accustomed because you do not taste foods in other countries. Bitter, is it because of the application of chemicals?

Where is @UKBengali? Your dream of a population at 200 million will soon materialize. Cheers!! The enlarged population will certainly make BD a very strong nation on Earth.অন্যদিকে বাংলাদেশ ধান গবেষণা ইনস্টিটিউট-এর তথ্য মতে, ২০৫০ সালে বাংলাদেশের জনসংখ্যা বেড়ে দাঁড়াবে সাড়ে ২১ কোটি এবং চালের চাহিদা বেড়ে দাঁড়াবে ৪ কোটি ৪৬ লাখ মেট্রিক টন।
The type of fertile soil you are asking do not exist anywhere in the world which is being long cultivated. Only uncultivated, virgin soil can be sufficiently rich in all those micro-nutrients you are saying lacking in Bangladeshi soil. Bangladeshi soil is being intensively cultivated for thousands of years. After so many years, you can not expect it to contain all micro-nutrient to exist in sufficient quantities. This is the case with all other agriculturally productive land in the world. Even if we get any such piece of land which is rich in all these micro-nutrients, after cultivating some years, it will became deficient of these elements. So what you are asking from Bangladeshi soil is unrealistic. This is not the type of fertility we are talking about.Contrary to what we love to believe, Bangladesh soil is not fertile. It has deficiencies in many organic substances requiring the infusion of inorganic fertilizer in all the crops.

Japan, Korea rely on food imports. Their food self sufficiency is 40 and 47 percentage.BD agriculture yield is very low compared to those of Japan, South Korea or Taiwan. Its acreage is much high, so the product total is also high. BD is 85% flat with 77,642 sq.km. of farmland. To know about the yield with Japan, please read the excerpt below:
"The most striking feature of Japanese agriculture is the shortage of farmland. The 49,000 sq.km under cultivation constituted just 13.2% of the total land area in 1988. However, the land is intensively cultivated".
This 13.2% of arable land consisting of only 49,000 sq.km. that feeds 126 million people here. In comparison, (77,640 x 2 seasons) = 150,000 sq.km. feeds 160 million people in BD. Note that the cold climate there causes only one paddy season in Japan. Whereas, a sunny country BD has two paddy seasons.
It means BD paddyland is essentially 150,000 sq.km. and Japan's only 49,000 sq.km. Yield in South Korea and Taiwan is also very high after Japan introduced its agriculture seed and technology there in the around early 1900s.
Without a good variety of seeds and home-made agricultural machines, we have a long way to go to achieve parity with these highly developed countries.
Yes mechanization is the key to increase yields and farmers incomes. There are still manual labor but in large parts of Vietnam rice planting and harvesting are fully mechanized. We need less people, our rice yields are twice of Thailand.@jetray, in the picture below people are doing manual during harvest. So, mechanization is needed to lower the cost of products. Instead of manual, a mode of motorized transport is needed. Mechanization must continue. The unemployment created in the farms is more than compensated in the factories and construction. Total production goes up, people's earnings as well.
Modern civilization is based on the mechanized production of everything. This is how a country's economy grows. The alternative method is to reduce the population. But, it is not possible.
I wonder where this minister wants to sell the surplus? As far as I know, all the countries of the world are self-sufficient in staple food. Some countries in Africa are in distress because of terrorism and rice is not popular there. Yemenis might love rice but it must go through UN Missions. Indirect or direct BD export there will only create ire of SA. So, which countries are the market for rice?
Usually, the govt collects the surplus rice in the season to be sold off-season. But, watching what people are talking, the bonafide GoB will first construct many warehouses before it can buy and stockpile. So, I do not really understand this export process.
How about asking organizations like UNCHR to buy the surplus rice from BD govt and distribute among the Rohingyas?
