Soil analysis methods and methods of work


Hello! I am 12 years old. I have been doing agricultural technology for about a year now. This summer, in an old extension at the dacha, I equipped a small laboratory. I work so far only for relatives and friends of the family. I want to give my passion a serious continuation. To do this, I need a lot of information, analysis techniques, research, samples. I treat plants and I need such information about the analyzes, according to which I could do these analyzes and understand what is happening with the plant. I am interested in different methods, tricks, techniques. I will be happy to share mine. This year I am going to grow cucumbers in the open ground. I really need a good harvest. Please share your tricks, methods, techniques, samples. In general, all that is listed in the above. Please advise something about cucumbers. I did not understand a bit where the answer to my question will be here, so just in case I will leave mail ([email protected]). You can send your questions to this mail, I will try to help. I was at one lecture, I read many books by O. Ganichkina. I am writing out the magazine “My beautiful summer residence”. There is little information about the analyzes. I will share the seeds of marigolds and rose hips.

Of course, at home, it is easier and better to conduct a microbiological analysis of the soil. For example, in order to determine the soil's need for nitrogen fertilizers, it is necessary to take spent film, X-ray film or photo paper. Then put the strips in the soil in the top layer in three or four places under the shovel vertically, firmly pressing against the wall of the soil. Leave for five days. Then remove, dip three times in a bucket of water. If everything is washed away from the film and it becomes transparent, then the soil microorganisms are highly active. On the surface of the film is a layer of gelatin, and this is protein. When decomposed by microorganisms, ammonia is formed. During its interaction with other soil compounds, ammonium forms of nitrogen accessible to plants are formed. And where the gelatin on the film has completely decomposed, the film has become colorless, there is no need to make nitrogen fertilizers. If you have not discolored at all and remained black, then you need to add a full dose of nitrogen, about one tablespoon per square meter.If the bleaching is partial, you need to add a dose of nitrogen fertilizers according to the degree of decomposition: 70-50-30 percent.
And to determine the soil's need for phosphate fertilizers, you need to put a plate with a white cotton cloth or filter paper. Do it the same way as described above. Remember to press the fabric or filter firmly against the soil cut. Leave the fabric in the soil for 30 days. Then remove, clean from the soil and see the degree of decomposition. If the film that stood next to it for five days became discolored, and the fabric or filter paper decomposed by 75-100 percent, then the soil does not need nitrogen or phosphorus fertilizers.
