The Genesis of Soil

Soil protection in the first place its beginning from rock together with animal and vegetable decay, if one is crumbling long distances or periods when there were large masses of rock and can not imagine breaking up. Heat, water and friction acting largely responsible. By friction here the grating and grinding against the rock mountain is meant. Keep in touch the huge rock, a perfect chaos of them, scraping, settling against one another. What would be the consequence? Well, I'm sure you have all the work. This is what happened: rocks were worn, much heat was produced, rocks were together, pressed to form new rock masses, some parts may be dissolved in water. Why I almost feel the stress and strain of the whole. Can you do that? Even then, there were large changes in temperature. First of all heated to a high temperature, then cool gradually. Just think of the cracks, which is crumbling, the upheavals, that such changes must have caused! You know some of the effects of freezes in the winter and thaws abruptly. But the little examples of bursting water pipes and broken pitchers are as nothing that happens in the world in those days. The water and the gases in the atmosphere helped along this crumbling work. For all these measures the friction, which action we call mechanical, it is easy enough to understand how sand was formed. This is one of the major departments of the soil sandy soil. The sea shores are great masses of pure sand. If soil were nothing broken rock masses then indeed it would be very bad and unproductive. But the early forms of animal and vegetable life decaying part of the mountain and a better soil was conducted. So the soils we speak of as sandy soils have mixed with the sand other matter, sometimes clay, sometimes vegetable matter or humus, and often animal waste. Clay brings us directly to another class of soils clayey soils. It may happen that certain parts of the rock mass was dissolved when water trickled over them and heat was plenty and abundant. This resolution was largely because it called in the air a certain gas carbon dioxide or carbon dioxide. This gas attacks and changes certain substances in the rock. Sometimes you see large rocks sticking with parts looked as if they were eaten. Carbon dioxide did. It changed this eaten part into something else, which we call sound. A change is not as mechanically, but chemically. The difference in the two kinds of change is this: in the one case of sand, where a mechanical change went, you still have exactly what you started, except that the size of the mass is smaller. It began with a large rock, and ended with little particles of sand. But you had no other kind of rock at the end. Mechanical action might be represented with a cube of sugar. Let the sugar is b ig rock mass. Break up the sugar, and even the smallest bit is sugar. It's just the rock mass, but in the case of a chemical change, start with one thing and end up with another. It began with a large mass of rock that had a part in it, which was amended by the acid acting on it. It ended in being an entirely different matter, which we call sound. So in the case of a chemical change a certain something with and in the end we have launched a totally different thing. The clay soils are often mud soils because of the amount of water used in its formation called. The third type of soil we farm people have to do is lime soil. Remember, we are thinking of soils from the farm point of view. This soil was of course usually made of limestone. Only when a thing is mentioned about which we know nothing, comes another of which we are just as ignorant. It follows as a whole chain of questions. Now you are probably saying to you, how was limestone first formed? At a time long ago the lower animal and plant species collected from the forms of water particles of lime. With the lime they formed skeletons or houses about themselves as protection from larger animals. Coral is representative of this class of skeleton-forming animal. As the animal died the skeleton remained. Great masses of this living matter down all together, by age group, formed from limestone. Some limestones are still formed in such a way that the formation Shelly is still visible. Marble, limestone another, is crystalline character. Another well-known limestone chalk. You might want to know a way to always be able to tell limestone. Drop a little of this acid on some lime. See how it hisses and bubbles. Then some of the chalk and fall on the marble, too. The same bubbling takes place. So lime must be in these three structures. You do not have to buy a special acid for this work, even for the household acids like vinegar will cause the same result. Then the three types of soils, faced by the farmers has, and understand that we want. Firstly, learn his garden soil by studying it to know how to learn a lesson by study.
