Good afternoon, dear guests and subscribers of the "Build for Myself" channel!
In this article, I will consider two questions: Is it possible to plant trees near pits and is it possible to make pits near already fruitful trees. It would seem, what is the difference? In both versions, the tree and the cesspool are located next to each other, but there is a very significant difference ...
The thing is that by placing a hole near trees that have been bearing fruit for a long time, we can deliberately destroy the plant. No, not by the contents of wastewater, but by oversaturation of the soil with moisture.
Not all trees are capable of quickly rebuilding the food system. As the plant grows, its root system adapts to the chemical composition of the soil. If the water level is high on the site, then the roots always grow a few tens of centimeters from the surface and the construction of a drain pit will not be destructive for them. But if the water lies deep, then the roots of plants are always directed inward, and here, when a hole appears, the concentration of moisture can be detrimental to the plant, since it is used to drinking water from the depths, and not at the level 1-2 meters. Many trees simply do not have time to rebuild the root system for "superficial" nutrition, they begin to drop their leaves and rot.
It has been noticed that most fruit shrubs such as gooseberries, currants, raspberries, etc. - begin to bear fruit better as soon as a drain pit is being built nearby.
Thus, if the groundwater level is far from the surface of the earth, from 5 m or more, then it is better to refrain from building a hole near the trees.
As for planting young trees near existing pits ...
Friends, you can find a lot of conflicting information on the Internet. Some say that fruit trees should never be planted near pits, since the trees will be fed with waste and the fruits will be harmful, others they say that on the contrary, it is possible and necessary to plant, since the effluent is processed by bacteria and this is a very powerful fertilizer, always giving a very good yield.
I propose to understand this issue.
I would like to digress a little. I spent all my childhood and youth on vacation in the village, and there no one ever heard about septic tanks and sewage disposal machines in those years, everywhere there were drain pits everywhere. So, near our pit, as I remember now, there were two huge plums, a very sweet mulberry, a cherry and an apple tree. All childhood, our family members plucked crops from these trees and ate, and they are still alive and well :-)))
In fact, fruit trees are fertilized with the same manure and humus to this day, because there is no better fertilizer, because it is a mixture of mineral and organic components. We will not say that a pear fertilized with manure will contain manure inside the fruit! The substance in the role of fertilizer can in no way be transferred from the root to the fruit, because the metabolism of plants is the 6-7th grade in biology.
Not so long ago, we had a reunion, one of my classmates became a biologist. Here's what he says: trees, through the root system, feed only on simple substances (elementary components), such as nitrogen, phosphorus, calcium, iron, magnesium, sulfur, and chemically complex elements (washing powders and other detergents) roots simply cannot absorb until they are processed and decomposed by bacteria into simple components.
About the distance from the pit to the tree
Between the tree and the drain (cesspool) pit, a large indent is made only in one single case, if, expanding, it can damage the walls of the pit with its root system.
Table of building codes and regulations SNiP 2.07.01-89 *:
As for the direct construction of drainage pits, I to some extent agree that in an amicable way - you need to avoid them, since a person uses There is a lot of chemistry that gets into the ground with sewage, but not everyone has the means to build septic tanks or call a sewage truck every month. And there are a lot of corners in Russia where they simply do not provide such services and people pump out holes in villages and villages on their own.
That's all, I hope the article was useful to you!
