Nitrogen is an important chemical element for plant growth. Unfortunately, it constantly evaporates from the soil into the atmosphere, so it is important for gardeners to regularly compensate for the nitrogen deficit in the backyard for a good harvest. Organic fertilizers such as guano, manure, compost can become a source of nitrogen, but their acquisition requires material costs.
Feces content
There is another, extremely close and affordable source of raw materials for the production of organic nitrogen-phosphate fertilizers - the country toilet. Regularly there is a question of disposal of its contents, in compliance with sanitary and environmental standards. Mastering the technology of using faeces for fertilizing a site allows to solve these problems. 
The contents of the country toilet is rich in mineral and organic substances., which allows such raw materials as feces to be used for the production of fertilizers.
Many gardeners and gardeners, regardless of the cultivated crop, prefer organic fertilizers that can be obtained from animal waste or plant growing. Among them: manure, humus, bird droppings, rabbit droppings, compost, ash, peat, biohumus, siderats, bone meal, sawdust, feces.Human feces and urine contain on average:
- nitrogen - 1.3%, mainly in the form of ammonia;
- phosphorus - 0.3%;
- potassium is about 0.3%.
Did you know? The ancient Indians of Peru were well known properties of guano - remnants of the droppings of bats and birds. Guano brought to the fields where they grew maize. This was written by the Spanish researcher Pedro Cieza de Leon in the book "The Chronicles of Peru" in 1553.
Can I use in pure form
In the "original" form, the contents of the cesspools are used extremely rarely. There are several reasons for this:
- This method is not hygienic, not recommended for garden crops and berries.
- Possible contamination of soil and groundwater.
- Salinization and alkalization of the soil, increasing the chlorine content.
- Most of the nitrogen is lost.
- The method is quite time-consuming.
In a number of countries, the use of feces as fertilizer in its natural form is prohibited by law, despite the fact that large companies are engaged in the production of fertilizers from human excrement. 
Excreta contain more than 20 types of conditionally harmless bacteria. Being in different parts of the intestines, they perform a unique function, helping to digest food. Getting into other parts of the digestive system, some bacteria, such as E. coli, cause serious infectious diseases. You can also become infected with parasites, so it is hardly worth fertilizing the garden with human feces.
Important! The contents of the cesspool may contain worms eggs that are resistant to low temperatures and dehydration. Getting into the soil, these pathogens can be in the fruits that grow on it. Having eaten such fruits without heat treatment, you can seriously get sick.
When using fecal masses, as well as any fertilizer, it is necessary to follow certain safety rules.
Some experts allow the use of feces in its pure form, as a fertilizer for ornamental plants and hedges. 
In the fall, when harvesting cesspools, when the harvest is gathered, a trench 0.5 m deep is dug near the plants, length is necessary. The trench is poured the contents of the cesspool, which is plentifully poured from above with earth taken out of the trench. Rammed.
In other sources offer the contents of the toilet 1-2 times a week, dropping to a depth of 30-40 cm in different parts of the garden. The main thing is not to repeat, and fertilize consistently in different places, observing the interval of several months. In addition to a regular clean toilet, the bonus will be that the moles and voles are afraid of the smell of feces and leave the garden.
For the preparation of solutions and infusions for feeding feces can not be used.
Did you know? The method of composting organic waste in the pits, for the enrichment of the soil owned by the Polab Slavs - Venda in X-XII centuries.
Vegetable fertilizer
There are more effective, aesthetic and safer ways to make fertilizer from human feces (at home).
Peat toilet
An alternative to the accumulation of feces in the cesspool, where they become a breeding ground for flies and unpleasant odors - peat toilet. 
For his device need:
- A tank or box of sufficient volume (15-20 liters) that does not let water through.
- Dry peat, straw waste or sawdust - the lowest grade material is suitable.
- Superphosphate - its addition to the tank, in minimal doses, will shake it completely to get rid of the smell and flies, will keep the concentration of nitrogen.
For convenient removal of the tank with the contents of the toilet seat flip. You can buy a finished toilet suitable design. Superphosphate in the tank is added in small doses of -2-3 kg per 100 liters of feces.Compost pile
The next stage of processing in the fertilizer fecal "raw materials" from the peat toilet - fermentation and disinfection, which will need a compost pile. In the process of decomposition of organic matter, a temperature of + 50-60 ° С is reached and maintained for a long time, which is destructive for most parasites and harmful bacteria. At the same time, nitrogen and other trace elements form compounds that are easily absorbed by plants.
Important! For the equipment of the compost pile or pit, a place is allocated in the far corner of the site, away from the places of rest, reception and cooking. It is quite logical to arrange it not far from the toilet.
Choose a round or square pad on which is poured:
- a layer of peat or sawdust 30-40 cm;
- wood ash (from the stove, fireplace or barbecue).
A recess is made in the center into which the contents of the toilet tank are laid out at 20-30 cm alternating with layers of peat or sawdust. Peat moisture should not exceed 60%. From above poured a layer of peat or sawdust, 20 cm thick. The contents of the heap, not rambuya, cover with polyethylene so as not to fall precipitation. The maximum height of the heap is 1-1.5 m. 
The temperature sufficiently high for disinfection is stored in the center of the heap, therefore fertilizers are taken from there for application to the soil, and the mass at the edges of the heap is moved to the center at the next tab.
To speed up the process of fermentation in the compost at the tab, you can add biologically active drugs. Compost ripening time with this method of bookmarking is 2-3 months, for safety it is doubled.
Adding land to such heaps reduces the temperature and degrades the result; the compost does not ripen. Worm eggs die in a compost heap with earth after a year and a half.
Did you know? You can add a few ordinary tin cans to the compost pile. In the process of iron oxidation, additional heat is released, the mixture is enriched with iron compounds.
What crops to make compost for
Compost use is determined by the criteria:
- Safety and health standards.
- The quality of the soil.
Today, the fertilizer market is represented by the broadest assortment for all types of plants and for any purse. However, gardeners and gardeners prefer to fertilize their plots with organic fertilizers - manure: horse, pig, sheep, rabbit, cow.
In terms of health security, more careful gardeners allow the introduction of aged for at least one and a half years in the hot compost pit of fecal compost for such cultures:
- fruit trees, nuts;
- grapes;
- cultures that are consumed after heat treatment - potatoes, zucchini;
- cereals, sunflower;
- lawns, hedges and flower beds.
Important! For clay soils, instead of fertilizer based on manure of any origin, it is recommended to use peat or vegetable compost.It is also necessary to take into account that any manure can:
- burn the roots of plants;
- change the acidity of the soil;
- suck it up with micro and macro elements.
Fecal based fertilizer
In the USA, Milogranit is produced by industrial method from feces using calcination, disinfection and fermentation processes. Use such fertilizers only for ornamental plants and lawn grass. In the cultivation of food they are not used. Potassium humate is also represented on the market; fertilizer is also obtained by industrial processing of feces.
Fertilizers from urban sewage faeces contain too much heavy metal salts, which accumulate in the soil and fruits.
