Soil origin.

If you can imagine a long stretch or period of time the soil was mainly due to heat, the action of water, friction, mainly when it had its beginning from the rock along with the collapse of animals and vegetables . Friction here means friction and grinding of the rock against the rock. Think of huge rocks, those perfect disorders, the bumps that settle against each other, the rubbing. What is the result? Well, I'm sure all of you will work. What happened this: a bit of rock was worn out, a lot of heat was generated, a piece of rock was pushed together, a new rock mass was formed, and some was dissolved in water. Why, I myself almost feel it all stress and strain. Can you do it?

And, too, there was a big change in temperature. At first everything was heated to high temperature and gradually cooled down. Cracks and disruptions are the reason why such changes are necessary! You know some of the sudden freezing and thawing winter effects. However, small examples of water pipes and broken pitchers are nothing to do with what happened in the world at that time. Water and gas in the atmosphere were helped along with this disintegrating work.

It is easy to understand how sand is formed from all the actions of this friction we call mechanical. This represents one of the great divisions of soil sandy soil. The sea coast is a large chunk of pure sand. If the soil is nothing broken stone mass and it is very poor and unproductive. However, the early decay of animals and vegetables became part of the rock mass and a better soil was born. Thus, soils that talk as sandy soils are mixed with other substances of sand, sometimes clay, sometimes vegetables and humus, and often animal waste.

Clay brings us to another class of soil clay soils right. Some of the rocks are dissolved water which is trickled and used abundantly with heat. This dissolution mainly occurred because of the presence of a specific gas called carbon dioxide or carbon dioxide in the air. This gas attacks and changes specific substances in rocks. I can not find a part of Aomo International Rock but I can eat it. Carbonation did this. It turned this eaten piece into something else we call clay. These changes are chemical rather than mechanical. In one case of sand where mechanical changes have occurred, you still have only what you started and save that the size of the mass is small You start with a large rock, small particles of sand It ended in. But you did not have another kind of rock at the end. Machine action may be described as a piece of mass sugar. The sugar represents a large chunk of rock. Break up the sugar and even the smallest bit is sugar. It is just like a rock mass; but in the case of chemical change, you start with one and end with another. You started with a large chunk of rock that had a part that became to be modified by the acid acting on it. It ended up being something else we call clay. So, in the case of a chemical change, something specific is started with and finally we have something totally different. Clay soils are often referred to as muds because of the amount of water used to form them.

The third kind of soil we have to deal with is lime soil. Remember that we are thinking about the soil from the farm's point of view. Of course, this soil was usually formed from limestone. I do not know what I want to do, but I do not know that others have appeared. And a series of questions will follow. There will now be "made of limestone that we talked about within ourselves?

Lower animal and plant forms once chosen from lime water particles before age. With lime, they formed a skeleton or home about themselves as protection from larger animals. Corals are the representative of this class of skeletal animals.

As the animal died, the skeleton remained. When a large amount of organisms are pressed, the age is formed of limestone. Some limestones are still shaped so that the formation of shelly is still visible. Marble, another limestone, is somewhat crystalline in character. Another well known limestone is chalk. Maybe I always want to know how to say limestone. Drop some of this acid into some lime. See how it bubbles and fizzles. Then drop some on this chalk and marble. The same bubbling takes place. Lime is the structure of these three. You do not need to buy a special acid for this task, as even household acids like vinegar produce the same result.

And these are the three types of soil that farmers have to deal with and we want to understand. Studying one language in the soil of Chizo will be studied by a class to learn as one.
Cultivation of vegetables.

Before taking garden vegetables individually, I must outline the general practices of cultivation, which apply to all.

The purpose of cultivation is to stimulate growth by removing weeds, (1) airing the soil to free the plant's diet, and (2) saving water.

As for weeds, the gardener of any experience does not have to be told the importance of keeping his crops clean. He learned the price of getting bitter and expensive experiences to get them anything similar to the start. He knows that one or two days of growth, after they have been enough, perhaps a day or so followed by a rain, easily double or onion or carrot pa He also grows daily Recognized to mean available plant food stolen from under legitimate crop roots.

Instead of allowing weeds to get with every plant food, he should supply a lot of clean, because frequent cultivation only mechanically breaks the soil, long before the science of the case was discovered, the soil Growers learned by observing the need to keep the soil clean for growing crops. Even a glorious aboriginal, his squaw not only put a bad fish under the corn hill, but also see it lied on the shell of her shell Plant needs to breathe. Their roots need air. You may also expect to find a rosy glow of happiness on the cotton milk child slave wan cheeks rich dark green of life of healthy plants in the asphyxial garden

Important as a matter of air, that of the water is ranked next to it. You may not often first see what the problem of cultivation has to do with water. But let us stop the moment and look at it. Take a strip of blotting paper, soak one end with water, soak through the blotter, run the hills and watch for moisture. Researchers labeled "capillary attraction" the slow flow of water is a blotter paper with a slightly invisible tube-forming texture. Now take a similar part, cut it, grasp the two cut ends tightly together and try again. Humidity refuses to cross the line: the connection has been broken.

Similarly, the water stored in the soil after the rain begins immediately to escape to the atmosphere again. That of the surface first evaporates and it dips into the surface and begins to dip through the soil. It's leaving your yard, through millions of soil tubes, just as surely as you had a two-inch pipe and a petrol engine that stopped storing yard and is its waste. This is the easiest thing in the world to cut two pipes. For most small vegetables the soil tube is kept broken by frequent cultivation of the surface not several or two inches deep, and the dust cover Try to get over every part of your garden especially Once every ten days or two weeks, where it is not covered by shadows. Is it like too much work? You can walk and push the hoes of your wheels fast, thus keeping the dust cover as constant protection. If you are waiting for weeds, you should almost crawl, lose all plant food by disturbing your growing plants more or less harm if gardening beginners are not convinced by the fact that they were given , There is only one left to persuade his experience.

The question of the way is a matter of course, as this matter has given so much space for constant care reasons. Get the wheel kite. The simplest sort not only saves you endless time and work, but also does a much better job than you can do by hand. You can grow good vegetables, especially if your garden is very small, without any of these labor savings, but I do not

With wheel bale, the task of storing soil mulch becomes very easy. Very quick work for small areas can be done with rice husks, if one does not have a wheel axe.
