Engaged in agricultural technical services for ten years, it has been found that fruit farmers have always been fond of manure, and even some people spend thousands of dollars a year to buy a few cars or even a dozen trucks of manure directly to the field, looking distressed and unable to stop it.
Today, I will popularize the differences and various contents of various manures, and remind the fruit farmers not to enter the ground without decomposing manure. Use less manure and more commercial organic fertilizers and bacterial fertilizers.
01 Pig manure
Pig manure contains 15% organic quality, nitrogen (N) 0.5%, phosphorus (P2O5) 0.5~ 0.6%, potassium (K2O) 0.35 ~ 0.45%, pig manure texture is finer, the composition is more complex, containing protein, fat, organic acids, cellulose, hemicellulose and inorganic salts. Pig manure contains more nitrogen and a smaller carbon-nitrogen ratio (14:1), which is generally easily decomposed by microorganisms and releases nutrients that can be absorbed and utilized by crops.
02 Cow dung
Cow manure contains 14.5% of organic matter, nitrogen (N) 0.30 to 0.45%, phosphorus (P2O5) 0.15 to 0.25%, potassium (K2O) 0.10 to 0.15%. The organic matter and nutrient content of cow manure is the lowest among all kinds of livestock, with fine texture, more water content, slow decomposition, low calorific value, and is a late-acting fertilizer.
03 Horse dung
Horse manure contains 21% of the organism, nitrogen (N) 0.4 to 0.5%, phosphorus (P2O5) 0.2 to 0.3%, potassium (K2O) 0.35 to 0.45%. Horse manure has more cellulose and hemicellulose content, in addition, it also contains lignin, protein, fat, organic acids and a variety of inorganic salts. Horse manure has a rough texture and contains a large number of high-temperature fiber decomposition bacteria, which can produce high temperatures during the procedure and is a hot fertilizer.
04 Sheep dung
Sheep manure contains 24 to 27% of the organic matter, 0.7 to 0.8% of nitrogen (N), 0.45 to 0.6% of phosphorus (P2O5), and 0.4 to 0.5% of potassium (K2O). Sheep manure contains more machinery than other animal manure, and the manure is finer and the fertilizer is thicker. The fever of sheep manure is between horse manure and cow manure, and it is also a hot fertilizer.
05 Poultry manure
Poultry manure is a general term for chicken manure, duck manure, goose manure, pigeon manure, etc. The nutrient content in poultry manure is higher than that in livestock manure, and the nutrient content is relatively balanced. Nutrient content table of common avian faeces
Poultry manure is an organic fertilizer that is easily perishable. The nitrogen in poultry manure is mainly uric acid, uric acid can not be directly absorbed and utilized by crops, and it is harmful to the root growth of crops, at the same time, fresh poultry manure is easy to attract underground pests, therefore, poultry manure as fertilizer should be accumulated and decomposed before application. Generally, poultry feces contain 1 to 2% calcium oxide. Poultry manure can produce high temperature during the accumulation and decomposition process, which is a hot fertilizer.
The above is the content of various manure, reminding the fruit farmers to choose reasonably and ensure that the rot is in place before entering the ground.
