Inspection heating

manureMaterials are used to heat the inspection, which are broken down by bacteria, which is accompanied by the release of heat. It may be manure, straw, leaves of the trees, municipal rubbish. The action of bacteria begins at temperatures above 0 ° C, optimal humidity is 65…70%, and the reaction should be neutral. Horse manure is best, which heats up slowly, but it warms for a long time. Cattle and swine manure, after mixing with straw, sawdust or leaves, and sheep and rabbit manure after moistening, also suitable for heating the inspection.
Due to difficulties in obtaining the above-mentioned materials, they can be replaced with chaff, hay, straw, bean leaves, peas or lupins, leaves, corn stalks, to which as a medium for bacteria is added to each 10 kg of material 40 a dag of nitrogen fertilizer, 20 day superphosphate, 10 dag of 40% potassium salt and water. Humidity works, squeezing the fabric in your hand. The hand should be moist after squeezing, but the water should not drip from it. The materials are prepared two weeks before the establishment of the inspection, because it takes so long to heat them up.
The earliest warm frames, biologically heated, mono-pitches are assumed in January, warm gable – in February, and winter ie. without heating and traveling chests – in March. Fresh manure or warm manure in a heap is suitable for heating the inspection. For this purpose, it is placed loosely into a narrow 2-gauge shaft…3 and height 1,5 m. Po 3…5 days, the manure heats up to the temperature of. 60…70°C. If it does not heat up for too long, it is poured with hot water or lumps of un-slaked lime are put in. Too wet manure should be mixed with dry leaves or straw. At location, where is the inspector to be, a layer of leaves is laid, protecting against the penetration of heat into the ground. A 3-layer layer of manure is spread on the leaves…7 cm. The undercoat should be about 80 cm wider and longer than the dimensions of the box. A box is placed on the manure layer and it is filled to the brim with manure, by lifting the compresses to its height. Then the frame is covered with windows and mats. Po 2…3 days, the manure that has cooled down during the inspection is reheated, what you can recognize by the condensation of water on the windows. Then he is trampled hard, covered with leaves or a two-centimeter layer of fine limestone, and on top of it he pours the soil under the frame (15…20 cm) and the inspector closes. Po 1 …2 days, when the earth heats up, you can start sowing. The land on the ground is prepared in the fall. For this, clay and sand are mixed with the manure land, compost or peat and stacked. The prism is covered with leaves, so that it does not freeze. Before use, it should be disinfected by steaming. There are special stoves in horticultural farms, in which the soil is subjected to steam at the temperature of. 100° C by 30 min. In home conditions, this procedure can be replaced by pouring boiling water over the ground and placing the pot with the ground on the hob over low heat or roasting it in the oven by 30 min.
