Description
Humic acid is widely exists in the
nature of macromolecular organic material, widely used in farming,
forestry, animal husbandry, petroleum, chemical, building
materials, medicine and health care, environmental protection and
other fields.Especially
now advocate ecological agriculture construction, pollution-free
agricultural production, green food and pollution-free green, more
make "humic acid".Facts
have proven that human life and survival depends on humic
acid.
Humic
acid has special function, it will prevent sandstorm, soil
improvement, urban sewage treatment, aquaculture, ecological
agriculture construction, development of production of green,
organic products, medicines, health care products play a unique
role.
Humic acid is a natural macromolecular organic
polymer, mainly divided into fulvic acid, brown rot, black rot acid
acid and so on, has the chelation and adsorption, penetration,
bonding, exchange, dilution, slow release, stability and surface
activity and other physical and chemical properties and biological
activity, has become a green power for the sustainable development
of national economy.Abroad,
humic acid has been developed in the field of agriculture and
industry more than *0 applications, application market has huge
potential.In
recent years, humic acid fertilizer development is rapid, fulvic
acid can improve soil structure, especially for a single for a long
time use of fertilizers in soil harden has significant
improvement.For
poor and desertification, soil humic acid can increase the cation
exchange capacity of the soil, the soil was fixed in the metal
cation as beneficial to plant (K +, Mg +) into the form of a can be
absorbed, and then promote the plants to absorb nutrient
elements.In
the soil of harden, humic acid can be to the role of beneficial
bacteria in the soil, in turn, make soil loose structure, but also
promote the plants to absorb nutrient
elements.
Neutralize acid and alkaline soil, mixed soil
PH.Many
basic elements and trace elements in the alkaline soil in the form
of can\'t be absorbed by the plant, can have the effect of buffer
PH, humic acid and the basic nutrition elements and trace elements
into being in the form of plants that can
absorb.
Heavy metals in acidic soil, but with reaction,
reduce the pollution of heavy metals and the soil at the same time
be Ca3 + Fe3 + Al3 + fixed phosphorus release can be absorbed by
the plant;In
higher salt content in soil by base exchange capacity replacement
absorbed by crops.Promote
the growth of plants.Enhance
the capacity of cold resistance, drought resistance of crops,
conferring, increase production at the same
time.
Humic acid on the soil of the above, plus can
promote the photosynthesis, promote cell division, can promote the
increase of sugar and the increase of nutrients, increase nearly
*0%.Humic
acid with harmful nitrate in the soil, avoid getting into
underground water, protection of water
resources.To
increase the effect of pesticides and herbicides, at the same time
reduce the pesticide
residue.Therefore,
the international fertilizer industry association said: "between
humic acid food chain, make soil more fertile, make food
safer.
Humic acid organic fertilizer, easy to use, the
effect is obvious.Can spraying on the leaf, watering,
ploughing
Above is a basic introduction of humic acid, the
hope can help you to cognitive humic acid, thank
you
