If you could imagine a long stretch or a period of time the soil was primarily caused by heat, water action, friction, mainly when having had its beginning from the rock along with the collapse of animals and vegetables . Friction here means friction and grinding of rock to rock. Think about huge stones, their perfect disorder, conflicting resolving against each other, rubbing. What is the result? Well, I'm sure all of you will succeed. What happened is this: a bit of rock wears, a lot of heat is generated, rock pieces are pushed together, a new rock mass is formed, and a part has melted in the water. Why, myself, I almost feel it all stress and distortion. Can you do it?
And, too, there was a big change in temperature. At the beginning, everything was heated to high temperature and gradually became cold. The confusion of the cracks, collapse, such a change is a necessary factor! You know some of the winter effects of sudden freezing and thawing. However, there is nothing that has happened in the world at that time, a small example of a rupture of a water pipe or a broken pitcher. Water and gas in the atmosphere were helped along with this collapsing work.
It is easy to understand how sand was formed from all the effects of this rubbing we call mechanical. This represents one of the great divisions of soil sandy soil. The coast of the sea is a large mass of pure sand. If soil is nothing broken stone mass and absolutely it is very poor, unproductive. However, early decay of animals and vegetables became part of the rock mass, better soil was born. So the soil that talks as sandy soil is 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 soil on the right. It was rich in which some rocks became dissolved trickled and it used a lot of heat. This dissolution mainly occurred due to the presence of specific gases called carbon dioxide or carbon dioxide in the air. This gas attacks and alters certain substances in the rock. Aoamo International Rock part I can eat it although I can not find the commitment. Carbonate did this. It changed this edible part to something else we call clay. Such a change is not mechanical but chemical. In one case of mechanical change, you still have only what you started and preserve that the size of the mass is small You start with a big rock and a small particle of sand It ended with. But you did not have another kind of rock at the end. Machine action may be explained as part of a solid sugar. Let sugar represent a large mass of rock. Split the sugar, and even the smallest bit is sugar. It is just like a rocky mass; in the case of chemical change, you start with one thing and end with another. You started with a big chunk of rocks that had parts that became to be changed by acid acting on it. It ended in a completely different thing we call clay. So, in the case of chemical change, something of a certain begins with, and in the end we have totally different ones. Clay soil is often called mud because of the amount of water used to form it.
The third kind of soil we must deal with is lime soil. Remember what we are thinking about the soil from the farm point of view. Of course, this soil was usually formed from limestone. I do not want to do anything, but I do not know that anything else has appeared. And a series of questions follows. Is there formed now "is formed of limestone that I talked about myself?
Lower animal and plant forms once chosen from lime water particles before age. With lime, they formed a skeleton and house about themselves as protection from larger animals. Coral is representative of this class of skeleton-forming animals.
As the animal died, the skeleton remained. Pushing lots of living things, it will be formed of limestone, age. Some limestone is still shaped so that shelly formation is still visible. Marble, another limestone is somewhat crystalline with properties. Another well-known limestone is chalk. Perhaps I always want to know how to say limestone. Drop a bit of this acid on some lime. See how it fizzles with foam. Then drop some on this choke and marble. The same bubbling is done. Lime lime has these three structures. Even household acids like vinegar will produce the same results so you do not need to purchase special acid for this work.
And these are three types of soils that farmers must deal with, we want to understand. Studying a single word through a lesson learned as a single study abroad in the soil of the garden.
Cultivation of vegetables.
Before taking the garden vegetables individually, I must outline the general practice of cultivation applied to all.
The purpose of cultivation is to remove weeds and to stimulate growth by (1) freeing the plant's food by placing air in the soil, and (2) saving moisture.
Regarding weeds, every experience gardener need not be told the importance of keeping his grain clean. He learned from the bitter and expensive experience the price of making it get anything similar to the start. He knows that the growth of one or two days, after they are sufficient, probably followed the rain days or so, easily double or onion or carrot he also daily growth , It means that it means available vegetable food stolen from under the root of legitimate crops.
Instead of allowing weeds to get with any vegetable foods, he should supply a lot of cleaner, frequent farming only mechanically, but not long before the case science was discovered, soil The growers learned by observing the need to keep the soil clean for growing crops. However, the ridiculous Aborigines need to breathe the plants that it sees that his squaw not only places bad fish under the corn hill but also plies her shell hoe on top of it. Their roots need air. You may also expect to find a rosy rose color of happiness on cotton Miruko slave wan cheeks in a suffocating garden rich dense green of healthy plant life
What is important as a matter of air is that of water it is ranked next to it. You may not first see what cultivation problems have to do with water. But we stop the moment and let's see to it. Take the strip of blotting paper, soak one end with water, soak it through the blotter, run the hill and see the moisture. Researcher 's sign "Capillary Attraction" It is a blotting paper which shows the texture of tube formation which can not be seen a little until the slow flow of water. Now take a similar part, turn it off, grasp the edges of the two cuts tightly and try again. Humidity refuses to cross the line: the relationship has been broken.
Likewise, the water stored in the soil after the rain will begin soon to escape into the atmosphere again. It first evaporates and soaks on the surface it begins to soak through the soil to the surface. It is your waste leaving your garden, through the millions of soil tubes, as well as surely you stopped preserving your garden you had a two inch pipe and a petrol engine. This is the easiest thing in the world to do to cut two pipes. Dirty two or two inch soil, not deep enough for most small vegetables kept soil tubes broken by frequent farming on the surface and dust roof covering every part of your garden Especially try to overcome every part of your garden Where it is not covered with shadows, once every ten days or two weeks. Does it seem to be too much work? As you walk you can push your wheel hoes fast, thus keeping the roots of dust as constant protection. If you are waiting for weeds, you should almost crawl, if you are not convinced by the fact that novice gardening who loses all the plant foods by disturbing your growing plants more or less harm is given There is the only thing left to persuade his experience.
Because of this problem gave so much space for the reasons of constant care, the problem of the method is obvious. Get a wheel hoe. The simplest sort will not only save you infinite time and work, but also do much better work than you can do by hand. You can grow good vegetables, especially if your garden is a very small one, without any of these labor savings, but I
With the wheel hoe, the task of saving the soil multi will be very easy. If one does not have a wheel hoe, a very quick work for a small area can be done with a chaff hoe.
