Inorganic fertilizers are stored in good covered dry rooms with a timber floor. It is impossible to put fertilizer on an earthen floor in order to avoid humidifying.

Absence of moisture in a room is the basic condition of successful storage. If air in it damp, fertilizers necessarily cover with something (straw floor-mats, a canvas). At wrong storage nitric and potassium fertilizers become compressed, superphosphate badly diffuses, their nutritional value is lost.

Manure is better to store in stacks. Stack it densely. On an impenetrable for liquid manure ground (for example, clay) at first 25-30cm a straw layer is put, then manure. A stack from every side is covered with the earth. Manure well rots in 8-10 months. To avoid nitrogen losses, to manure it is necessary to add superphosphate or a phosphorite powder (2.5-3kg on 100kg).

Poultry dung in order to avoid nitrogen losses should be stored in heaps in a mix with the dry ground, protecting from water which washes away nutrients. Nitrogen losses can be lowered, having added on 10kg a dung 1.5-2kg superphosphate and humus (10% of mass of dung). Sawdust and shavings for covering the dung does not suit; they strongly reduce its nutrient property.
