1、Farm manure includes manure and urine,compost,soil manure,oil cake fertilizer and humic acid fertilizer.
1.Feces and urine,feces and urine include human feces and urine,livestock and poultry feces and various circle fertilizers.Fecal and urine fertilizer is a complete fertilizer rich in calcium,magnesium,sulfur and a variety of trace elements.It is rich in organic matter and a variety of nutrients.The nutrients in various ring fertilizers are mainly organic,which can not be directly absorbed and utilized by crops.Fresh ring fertilizers should not be directly applied to farmland.They must be composted and fermented.Under the action of high-temperature fiber decomposing bacteria,they can be applied after being fully decomposed to improve fertilizer efficiency.
2.Composting and composting
Compost is the continuous accumulation and fermentation of crop straw,various garbage,fallen leaves,sludge,etc.to achieve the decay of these raw materials.Compost contains rich nutrients,which can not only provide crop nutrients,but also improve the soil.It is an organic fertilizer similar to ring manure,also called artificial manure.
3.Soil miscellaneous fertilizer,including all kinds of ash fertilizer,garbage fertilizer,mud fertilizer,rock ash,lime,gypsum,soil fertilizer and waste materials of slaughterhouse.A small part of soil and miscellaneous fertilizer can be applied separately,such as plant ash,rock ash,lime and gypsum.Most of them are mixed with other farm manure.
4.Oil cake fertilizer includes rapeseed cake,Tung seed cake,cotton kernel cake,tea seed cake,Chinese tallow seed cake,soybean meal,sesame cake,peanut cake,etc.these fertilizers have high organic matter content,generally 75-85%,rich nitrogen content,complete nutrient elements,and long-lasting fertilizer effect.The oil cake fertilizer should be applied after fermentation.
5.Humic acid fertilizers include peat,lignite,weathered coal,etc.the processed products include ammonium humate,ammonium humate phosphorus,phosphorus humate,potassium humate,sodium humate,etc.
2、Green manure is directly or indirectly applied as fertilizer by using cultivated or wild green plants,such as sweet potato,purple flower sweet potato,arrow pea,milkvetch,broad bean,pea and aquatic plants.
Organic manure mainly includes human manure,manure,compost and green manure.Farm manure has the characteristics of many kinds and fast fertilizer effect,which can not only improve the soil,fertilize the soil,improve the soil nutrient vitality,but also purify the soil ecological environment.
Human feces and urine are mainly farmyard manure after farmers are decomposed,composted and fermented into harmless treatment.They are high-quality organic fertilizers.
Organic fertilizer is suitable for all kinds of soil and also for many kinds of crops to promote the normal development and growth of root system.However,tobacco,sugar beet and other crops should be used less to avoid affecting the quality.
The composted and fermented human feces and urine can be used as base fertilizer and top dressing;Because it has the advantages of high nutrient concentration and fast fertilizer effect,top dressing is the best choice.
The manure is mainly the organic fertilizer made by composting and decomposing the manure and urine of livestock and poultry and bedding materials or organic additives.The maturity of the raw materials of the manure also determines the nature and quality of the manure.
Compost is mainly prepared without using any chemicals.Composting can reduce soil diseases and insect pests.It is the best method and high-quality improver for improving soil,and also improves the physical properties,chemical structure and biological environment of soil,so as to avoid breeding various viruses in soil.
In fact,in rural areas,there are many kinds of organic fertilizers with similar properties,which are very high-quality farmyard fertilizers.
