Description

one

The invention relates to the field of agricultural production and can be used as a complex fertilizer.

Known complex fertilizer, including phosphorus, potassium, molybdenum and boron. The content of molybdenum and boron is 0.25 and 0.83 weight, respectively. % (weight P205). A disadvantage of the known fertilizer is the absence of nitrogen in it, which is necessary for plant growth, as well as organic substances (manure, manure) 1.

The closest in its composition is a complex fertilizer, including dried manure, nitrogen, phosphorus and potassium. The specified fertilizer is obtained by homogenization of manure without air access, followed by its displacement with oil and maintained for three to four months. The resulting compost is shifted with peat moss and mineral fertilizers, in particular superphosphate, potassium nitrate 2J. A disadvantage of the known fertilizer is the absence of trace elements and the complexity of its preparation.

In order to increase the efficiency of restoring soil fertility and simplify the processing and storage of navo-ja. The proposed my complex fertilizer additionally contains micro: lemns with the following quantitative co-components, ijfc,%

To achieve this goal, the slurry is treated with air in a turbulent flow containing 1: 10–15 air in volume, followed by

adding gypsum in the amount of 1.5-6 weight. % (of the total weight of the slurry), the substance of the resulting mass in a fluidized bed at 300–500 ° C, and the introduction of mineral fertilizers and trace elements.

Example. Heterogeneous stratified slurry slurry taken from the tank, adjust the consistency so that the moisture content was. The mass is homogenized in a turbulent flow at

volume ratio containing air slurry equal to 1:15. After that, the free liquid is removed and the mixture is bonded with the addition of 1.5% gypsum to the total weight of the slurry. Then exist in a fluidized bed oven at

350 ° C. To 900 kg of dried manure is added, kg: 48 nitrogen, 22.5 phosphorus. 27.2 potassium, 0.3 boron, 0.5 copper, 0.8 cobalt, 0.6 iinka, 0.4 marganium, and 0.2 molybdenum (2.3 kg of microelements in total.

As a source of trace elements, the following is used: biorodatolite flour (1.5 2%

boron), 1I) ity cinders (0.2-0.4% copper), manganese sludge (14-14% manganese), zinc sulfate (2.7% zinc), cobalt sulphate (21% cobalt), molybdenum superphosphate ( 0.2% molybdenum).

Mineral fertilizers are applied in the form of water-soluble salts: nitrogen in the form of ammonium chloride with a nitrogen content (25%), phosphorus 13 in the form of a simple superphosphate (197 °), potassium in the form of a potassium salt (40%).

The resulting product has the following composition,%: organic matter 90, mineral nitrogen 4.8, phosphorus 2.25, potassium 2.72, boron 0.03. copper 0.05, cobalt 0.03, zinc 0.06, manganese 0.04, molybdenum 0.02.

Claims (2)

1. Complex fertilizer, including dried manure, nitrogen, phosphorus and potassium, characterized in that, in order to increase the efficiency of restoring soil fertility, it additionally contains trace elements with the following proportion of components, weight. %: Dried p) avoch 80-90 Nitrogen 1,5-7,5 1-5 Phosphorus Potassium 1.5-1.0 Rest Trace elements 2. A method of producing a complex fertilizer according to claim 1, comprising processing manure and introducing mineral fertilizers, characterized in that, in order to simplify processing and storage of manure, the slurry is treated with air in a turbulent stream containing by volume: 1: 10-15 air, followed by the addition of gypsum in the amount of 1.5-6 weight. % 5 (of the total weight of the slurry), drying the resulting mass in a fluidized bed at 300-500 ° C, the introduction of mineral fertilizers and trace elements.
