Is it possible to fertilize the garden with feces

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 be 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.

Human feces and urine contain on average:

• nitrogen - 1.3%, mainly in the form of ammonia;
• phosphorus - 0.3%;
• potassium is about 0.3%.

Urine plus organic residues of plant and animal food, water, enzymes, acids, are inhabited by various bacteria, Escherichia coli. They may contain eggs of intestinal parasites.

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.
• Salting and alkalizing 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 absorb 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.

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.

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 allow water to pass 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 retain the concentration of nitrogen.

The tank is placed in place of the sump, in a small depression.Like a cartridge from a dry closet. At the bottom of the tank, a layer of peat or sawdust of 20-25 cm is poured. Later, as the toilet is used, its contents are covered with dry peat or sawdust on top. Rainwater or snow should not fall into the tank. 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 it, 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.

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).

In the center they make an indentation in which the contents of the toilet tank are laid out at 20-30 cm, alternating them 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 is high enough for disinfection in the center of the heap, therefore, for fertilizing the soil is taken from there, 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 preparations. 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. Worms eggs die in a compost heap with earth after a year and a half.

What crops to make compost for

The use of compost is determined by the criteria:

• Safety and health standards.
• The quality of the soil.

Some sources propose to make compost from feces like ordinary manure.

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.

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 methods 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 that accumulate in the soil and fruits.
