Organic fertilizer and fertilizer mixed
benefits
1, each
other, fertility. Single nutrient fertilizer, high, fertilizer fast, but short
duration; organic fertilizer nutrient complete, lasting fertilizer can improve
soil fertility. Mix the two can complement each other, a comprehensive supply
of crop nutrient requirements, promote robust crop growth, increase yield
efficiency.
2, the fast
chemical dissolution, solubility big, applied into the soil, the soil solution
concentration of 1:00 will soon be increased, resulting in a higher osmotic
pressure to affect the crop nutrient and water absorption, increased nutrient
loss and opportunity. Organic and inorganic fertilizer mixed with the soil
solution can overcome the shortcomings of increased sharply, while the organic
fertilizer could improve nutrient uptake by crop conditions, improve water and
fertilizer retaining capacity of soil to prevent and reduce the loss of
fertilizer nutrients to improve fertilizer use efficiency.
3, to reduce
nutrient fixation and improve efficiency. Soil applied fertilizers, some
nutrients will be absorbed by soil, chelate, or fixed, lower fertilizer
efficiency. Such as superphosphate, and calcium magnesium phosphate fertilizer
applied directly into the soil, the soil easily with iron, aluminum, calcium
and combined to produce phosphoric acid insoluble material was fixed, resulting
in effective nutrient loss. If mixed with organic fertilizer application, not
only can reduce the contact surface with the soil, reduce soil and fertilizer
fixed opportunities, but also enable those insoluble phosphorus in the
phosphorus into crops to make use of phosphorus, increased phosphate
fertilizer.
4, to
improve soil structure, promote the sustainable yield. Long-term single
application of fertilizer will be destroyed in the aggregate structure of soil,
heavy clay soil caused by compaction, reduced fat Gengzuo performance and for
performance. Organic fertilizer rich in organic matter, loose soil can be
activated to reduce capacity; can improve the soil's water, fertilizer, gas,
heat and other physical and chemical properties; adjust pH. Mix the two, can
increase production, but also to promote the sustainable development of
agriculture.
5, the
promotion of microbial activity, increase soil nutrients. Organic fertilizer is
microbial life, energy, fertilizer is inorganic nutrients for microbial growth,
the two mixed to promote microbial activity, thereby promoting the
decomposition of organic fertilizer to produce carbon dioxide and organic
acids, contribute to the unavailable soil nutrient solution, the supply of crop
uptake . Carbon dioxide can increase crop nutrition, increase photosynthetic
efficiency. Microbial life is short, death released after decomposition of
nutrients for crop uptake and utilization.
Second,
appropriate mix of organic manure and chemical fertilizer applied
1, manure,
compost or calcium magnesium phosphate and superphosphate mixed fertilizer.
Superphosphate and calcium magnesium phosphate fertilizer and manure, compost,
composting, after the application of mixed composting not only reduce the
contact surface of phosphate fertilizer and soil to avoid soil phosphate ions
are fixed, and the decomposition of organic fertilizers of various organic
acids, can promote was released from the soil fixed phosphorus for crop uptake,
fertilizer efficiency by one third.
2, manure,
compost mixed with ammonium bicarbonate and urea applied. In manure and compost
to add 0.5 to 1% ammonium bicarbonate (or acid), and human waste, beneficial
microorganisms multiply and activities to promote the decomposition of organic
fertilizer and a variety of nutrient release, to provide a rich crop
nutrients.
3, human
waste mixed with superphosphate or calcium magnesium phosphate fertilizer
facilities. Decomposition of human waste in the ammonium carbonate content in
too many single application easy to volatilization, or calcium magnesium
phosphate and superphosphate mixed fertilizer, through the nature of the
chemical reaction to form stable ammonium dihydrogen phosphate, which reduces
the urea nitrogen in human waste prime losses, increased phosphorus nutrition.
Paul nitrogen phosphorus, fertilizer greatly increased.
4, human
waste mixed with ferrous sulfate applied. In human urine by adding 0.5% ferrous
sulfate, allow human waste in the highly volatile nature of ammonium carbonate
into a stable ammonium sulfate, manure odor plays Paul, the role of preventing
the loss of nitrogen volatilization.
Third,
should not be mixed with the manure and fertilizer applied
1, no
composting of farmyard manure and N fertilizer application can not. If the
mixed fertilizer, manure in denitrifying bacteria will occur denitrification of
nitrate fertilizer to produce nitrite, lead to nitrogen loss, reduced crop
quality.
2, can not
plant ash and nitrogen fertilizer mixed. Ash is a basic fertilizer, if and
ammonia nitrogen, nitrate and other nitrogen fertilizer mixed acid, and
decomposition occurs in response to release of ammonia volatilization,
resulting in nitrogen loss, lower fertilizer efficiency.
3, plant ash
can not be mixed with the superphosphate applied. Ash calcium more, if mixed
with the SSP will generate insoluble calcium phosphate, so that P is fixed,
crops can not be directly absorbed and used.
4, plant ash and manure can not, compost, mixed with human waste facilities. Ash is generally treated as potash, alkaline, if and manure, compost, human waste mixed, will accelerate the evaporation of nitrogen to ammonia loss.
