When we start composting, it is very important what kind of waste we will use and in what proportion. The precipitation is divided into: GREEN – rich in nitrogen (N) and BROWN – rich in carbon (C).

Green – rich in nitrogen (N)

Farm waste:

• freshly cut grass;
•  manure;
•  fresh hay;
•  sandy soil;
•  fresh bird manure rotted manure and manure from cows, horses;
•  marc in the production of wine and brandy;
•  plant residues (eg leaves of carrots, potatoes and other root crops). From household waste: peels of vegetables and fruits, houseplants and garden flowers, dried flowers, tea bags, coffee grounds.

Brown – rich in carbon (C)

Farm waste:

• dried leaves and grass;
•  straw;
•  sawdust, bark, fresh sawdust;
•  hay;
•  corn;
•  manure mixed with straw litter;
•  wood ash;
•  twigs of branches;
•  Housekeeping: bread, pasta, cardboard packaging, newspapers, eggshells.

In order to obtain quality compost, it is necessary to mix the “green” and “brown” waste into 4 parts of waste rich in C (carbon), we add 1 part of waste rich in N (nitrogen). As “green” waste decomposes quickly and “brown” waste slowly, the composting process slows down when there is not enough “green” waste. When their quantity increases a lot in comparison with the “brown” waste, the quantity of the formed ammonia – gas with an unpleasant smell increases.

Waste that should not be used: Diseased and infected plants, manna tubers, tobacco mosaic, white rot. For example, do not use the underground part of the potatoes, but the leaf mass can be composted. Avoid putting in the compost pile waste products that you do not produce yourself and are not sure of their origin. In principle, almost all the waste we throw out of our garden is suitable for composting. From the household we should not use: meat, fish and bones, dairy products, fats and oils, cooked food, pet feces, charcoal and charcoal residues, residues of synthetic fabrics, plastic waste, metals.
