Different Soil for Different Crops - さまざまな作物のための異なる土壌



First and foremost, to find out the right soil and pH level for your trees is not rocket science. The pH scale indicates acidity or alkalinity. A soil with a pH number below 7 is acid, while one with a pH above 7 is alkaline. Garden plants typically grow best in neutral or slightly acid soil (pH 7 or slightly below; see illustration at left). Most won't thrive in highly acid or highly alkaline soil, though a few have adapted to such extremes. In general, some nutrients cannot be efficiently absorbed by plant roots if soil pH is too high. If it is too low, on the other hand, nutrients may be taken up too efficiently: the excess cannot be processed fast enough and overloads a plant's system, causing it to languish and die.


Local climate gives you a clue to the likely soil pH. In high-rainfall areas, soils are often acidic. It's in these regions that you tend to find acid-loving plants like azaleas, rhododendrons, camellias, and blueberries. Alkaline soils, in contrast, are typically found in low-rainfall areas. Many of the plants popular for waterwise gardens--sorts that need little water once they are established--do well in soil on the alkaline side. The olive, native to the Mediterranean basin, is one example of a plant that thrives in alkaline soil; oleander (Nerium oleander) and pomegranate also perform well.

If you're not sure about your soil's pH, you can test it yourself with one of the inexpensive test kits sold at most garden centers. Such kits can be relied on to tell you whether your soil is basically alkaline, acid, or neutral. If you suspect that your soil is highly alkaline or acid--or if a do-it-yourself kit so indicates--you may want to confirm the diagnosis with a professional soil test. Such tests are analyzed by laboratories; along with the results, you'll normally receive recommendations for correcting the pH of the soil tested.


Lime, available in either ground or powdered form, is often suggested to raise pH. Ground limestone is the slightly less potent of the two and raises pH more slowly. The amount needed depends on the soil texture (more is needed for clay than for sandy soil, for example) and other factors. Wood ashes and oyster shell also make acid soil more neutral.

To lower pH, common sulfur is the least expensive choice, though ferrous sulfate and aluminum sulfate are sometimes recommended instead. Ferrous sulfate, which also adds iron to the soil, is of the most help to plants that show yellow leaves as well as overall poor health. You'll also lower the pH of alkaline soil over time by regularly applying organic amendments such as compost and manure.

To determine how much lime or sulfur to add, follow the advice included with your test results. If your soil is extremely acidic or alkaline and you need to change the level by more than one point on the pH scale, it's best to bring in a professional: he or she can both analyze test results and perform an on-site evaluation to determine whether the soil can be amended successfully and how best to go about it.

If amending the soil just isn't feasible, plant in raised beds filled with problem-free, well-amended topsoil; or choose native plants that thrive in the unamended soil.

Foods for example can be classified into two groups namely the acidic food group and the alkaline food group. These foods are categorized as such because they affect the urine pH level when they are consumed. Hence, taking in too much acidic food will lead to systemic acidosis whereas too much ingestion of alkaline foods may also lead to severe alkalosis. Nevertheless, the proper balance of acidic and alkaline food intake is required for various purposes.

To understand more about this concept, it is important to know about the pH scale. This scale runs from 0 to 14 with the bottom half (0 to 7) belonging to the acidic range and the upper half (7.1 to 14) belonging to the alkaline range. Under normal circumstances, the human body tries to maintain a slightly alkaline pH of 7.4 through mineral deposition and withdrawal from bones and soft tissues. It is said that 50%-80% of the daily food intake must come from alkaline foods to retain the body’s acid-base equilibrium.

Alkaline foods include fruits (citrus, watermelons, papaya, mango, grapes, melons, pears, apples, banana, kiwis, peaches, pineapples, cherries, avocados), a range of vegetables (parsley, spinach, okra, broccoli, squash, celery, green beans, carrots, beets, lentils, tomatoes, cabbage, cauliflower, turnips), oils (grape seed oil, olive oil, canola oil) and other food products like goat cheese, hazelnuts, chestnuts, raw sugar and wild rice among others.

Popular examples of acidic foods are blueberries, prunes, cranberries, white bread, prunes, pasta, wheat, pork, beef, shellfish, ice cream, peanuts, beer, alcohol, string beans, kidney beans, walnuts, plums, store-bought juices, rye bread, brown rice, organ meats, eggs, cold water fish, pumpkin, eggs, sesame seeds, corn oil, sunflower seeds, fatty dairy products, honey, margarine, lima beans, skinless potatoes, navy beans, pinto beans, canned fruits, oats, white rice, cashews, coffee, pistachios, wine, turkey, chicken, lamb and majority of condiments.

There are many health-conscious folks who believe that an alkaline-rich diet is better than its acidic counterpart. Having such will prevent too much acid from accumulating in the bloodstream as well as reduce the risk of degenerative disorders such as osteoporosis, heart disease, and cancers to name a few.

1. Basically, the majority of fruits, grains, and vegetables are alkaline foods while meat products are usually acidic in nature.

2. Because the body is slightly alkaline in nature, you must make sure to eat enough alkaline-rich foods because it is a lot healthier compared to eating too much acidic foods.




The story of Masanobu Fukuoka


Masanobu Fukuoka
Masanobu Fukuoka taking care of rice fields
Fukuoka was a plant scientist working in Japan in the 1940s, advising the government on the best crops and edible plants to sustain the country during the war. Shortly afterward, he had something of an epiphany about science and gave up his job and returned to the countryside to farm.

Science, Fukuoka concluded, is part of the problem, not the solution. It only seems to solve problems that it created in the first place, like a man who breaks his own roof and then is pleased with himself when he manages to fix it. When fields are ploughed, or trees are pruned, farmers create problems for themselves which means more work. Convinced there was a ‘natural’ way to farm without all these techniques, Fukuoka began experimenting with how little he could do. “I was aiming at a pleasant, natural way of farming,” he said, “which results in making the work easier instead of harder. ‘How about not doing this? How about not doing that?’ – that was my way of thinking”

Up in the mountains, he developed a method (or rather a non-method) that flies in the face of modern farming. “I ultimately reached the conclusion that there was no need to plow, no need to apply fertilizer, no need to make compost, no need to use insecticide,” he wrote. “When you get right down to it, there are few agricultural practices that are really necessary.”

This conclusion required a good deal of trial and error and lots of dead plants along the way. The One Straw Revolution tells his story, from his start as an idealistic young man to a troublesome visionary with a constant string of visiting experts, researchers, and traveling hippies wishing to learn his secrets.

Those secrets include such imaginative ideas as planting one crop before the other is harvested, so

that the new crop gets the jump on any weeds. Fukuoka grew his vegetables ‘semi-wild’ on the mountain slopes, sometimes pressing seeds into balls of clay so they wouldn’t be eaten by the birds, and then throwing them out to take their chances. He farmed rice and barley, harvesting it and scattering the straw straight back onto the fields, a policy of “returning to the soil everything grown in the field except the grain itself”. Nitrogen fixing ‘green fertiliser’ such as white clover grew across the ground in between crops and across the orchard floor around his citrus trees. Chickens and ducks roamed free and ate the insects.

But, you don’t really read The One Straw Revolution for gardening tips. For one thing, it’s only directly relevant to Japan. More importantly, the book is as much a work of philosophy as it is a life story or an explanation of natural agriculture. Fukuoka believed that we don’t really know anything about how nature works, and that much of modern farming was setting itself up for failure. He rails against growing out of season vegetables that are a “watery concoction of nitrogen, phosphorus and potash, with a little help from the seed”, and Japan’s growing taste for meat. He predicted that if the Japanese diet continued to change the way it was, there would be a food crisis in thirty years time. In that he was not uncorrect – Japan is the world’s biggest food importer, and has led the charge in land-leasing deals in Africa.

“If we do have a food crisis it will not be caused by the insufficiency of nature’s productive power, but by the extravagance of human desire”, he wrote, advocating a simpler lifestyle closer to nature. His simple living code extends to work too. “I do not particularly like the word ‘work'” he writes in my favourite little passage. “Human beings are the only animals who have to work, and I think this is the most ridiculous thing in the world. Other animals make their living by living.”

Fukuoka is an amiable and ingenious writer, and The One Straw Revolution is full of passion for the earth and its generosity, and bemused irreverence towards false ideas of progress. You won’t agree with everything he says, perhaps his views on education and health in particular, but this is nevertheless an unusually wise and refreshing read.

The five principles of natural farming - 自然農法の原則


The five principles of natural farming Permaculture -  自然農法の原則


Here is something interesting for all of you guys, a Tsunami of information to cure or at least to reduce some of our ignorance is often necessary; we don’t need millions of dollars in equipment to run a farm nor thousands of dollars to build our own Eden on earth. Before we start explaining about natural farming, it's important to understand and start with Permaculture. You will soon realize there is a connection between the two! Permaculture was created in the 1970s by Bill Mollison, an Australian ecologist and University of Tasmania professor. He had spent many years out in nature as a wildlife biologist observing how natural systems work and became very distressed at the destruction that he saw going on around him. He decided that instead of being angry about what was happening and reacting against the destruction he wanted to work on creating a positive solution And he thought the solution would be living based on the patterns he had observed in nature.

By observing nature, Mollison came up with several important insights. He observed that natural systems, such as forests and wetlands, are sustainable. They provide for their own energy needs and recycle their own waste. He also observed that all the different parts of a natural ecosystem work together. Each component of the system performs important tasks. For example, bees help to pollinate, birds provide pest control, and certain plants pull nitrogen out of the air and fix it into a form that other plants can use. So everything does useful work. He applied these and other insights to design and create sustainable agricultural systems.

In the 1970's he and his student David Holmgren wrote and published some books explaining his ideas. In the 1980s he published his design manual and started teaching permaculture design courses to spread his ideas around the world. By the 1990s permaculture had started spreading throughout the US, although it's more well-known in other countries around the world. To this day, it's continuing to grow as a global grassroots movement and people primarily learn about it through permaculture design courses and workshops that generally happen outside of academia.








Natural Farming recognizes that farmers and gardeners must first attend to nature so that they may then learn how to tend. This gentle practice turns farming from the science it has become in the West into a craft; where this craft is a focused understanding of the primacy of nature.




Temperate Natural Farming proceeds from simplification applying the ‘do-nothing’ approach from deep observation through opening ourselves to nature, which is the work of a lifetime. Curiously, as we progress along the path of Natural Farming there comes the realization this is not agriculture at all because it wants to go nowhere and seek no victory and, ultimately, it is not about the growing of crops, but the cultivation and perfection of human beings.


Masanobu Fukuoka
A simple farmer still ahead of his time
Natural Farming is truly inspired by Masanobu Fukuoka’s practices, in 1975 he wrote a book called The One-Straw Revolution that described his journey, his philosophy, and farming techniques. The One-Straw Revolution, in short, was Fukuoka’s plea for man to reexamine his relationship with nature in its entirety. In his most utopian vision, all people would be farmers. If each family in Japan were allotted 1.25 acres of arable land and practiced natural farming, not only could each farmer support his family, he wrote, but each "would also have plenty of time for leisure and social activities within the village community. I think," he added, "this is the most direct path toward making this country a happy, pleasant land."

Masanobu Fukuoka's legacy can be summarized as a profound shift in agricultural thinking, advocating for sustainable, low-impact, and nature-centric farming practices. His work continues to inspire individuals and movements dedicated to more ecologically responsible and regenerative agriculture.

I would highly recommend buying and reading it again and again because it tells so many facts and common sense about agricultural practices. In other words, it idiot proof that learning the basics of Natural Farming makes it really easy.





There are five principles of Natural Farming;
  1. No plowing – because it destroys the cycles of life in the soil, 
  2. No fertilizers – because they deplete the land from which they are taken and disrupt the balance of the soils on which they are used, 
  3. No pesticides – because there are no ‘pests’, 
  4. No weeding – because there are no ‘weeds’, 
  5. No pruning – because a tree left undisturbed knows far better how to grow.
Natural farming is founded on the laws of nature. It assumes that all that is needed to successfully produce crops can be found in the natural environment. Engaging in natural farming, therefore, is a desirable venture. I don't have the opportunity to make use of these practices in Singapore, but I have to be patient. Good things come to those who wait!

The Success Story of Yoshikasu Kawaguchi

Natural farmer and practitioner of traditional Chinese medicine of modern times. Born in 1939 to a family of farmers in Sakurai, Nara Prefecture, where he continues to live and work today. Began to work on the farm after graduating from junior high school but eventually experienced health problems, which he attributes to the use of agrochemicals. In 1978, inspired by the work of Fukuoka Masanobu and others, began to develop his own natural farming method, which has attracted numerous followers in Japan. Author of Shizen-nō ni inochi yadorite (Bringing Natural Farming to Life), Hajimete no shizen-nō de yasai-zukuri (Natural Vegetable Cultivation for Beginners), and other works.

An old phrase that has recently become popular again in Japan is “Shindo-fuji.” This means, literally translated, “Body and Earth Are Not Two.” That is our human bodies and the land from which we get our food are closely connected. This phrase is commonly used for promoting a closer relationship between consumers and farmers and also for promoting greater self–sufficiency regarding agricultural produce. In this context, the phrase generally supports the slogan “Produce locally, consume locally,” which is good for the health of both humans and the land. The popularity of this phrase reflects the increasing awareness of ecology and eco-economics in the society. Behind this awareness are things such as increased anxiety about the safety of food in Japan and increasing international pressure on Japan to import more agricultural produce.
