Calcium Lignosulphonate is used to chelate trace element fertilizer
Calcium Lignosulphonate:
When the soil is rich in nitrogen, phosphorus, potassium, calcium,
magnesium and sulfur, sometimes the shortage of one or several
micronutrients may become the limiting factor for the continuous
increase of agricultural production. The determination and
application of micronutrients in soil are very important in high
yield agricultural areas. Micronutrient fertilizer refers to a kind
of fertilizer containing one or more compounds of the crop
nutrients boron, copper, iron, manganese, zinc and molybdenum, and
the content can be indicated. This nutrient element is as important
to the crop growth process as other nutrient elements, but the
amount is very small.
In recent years, lignosulfonate microfertilizer has been paid more
attention because of its low production cost and slow release
effect.
Adding ferrous sulfate or zinc sulfate, copper sulfate, manganese
sulfate into lignosulfonate solution, stirring dissolution, filter
out the insoluble matter, and obtain the corresponding
lignosulfonate chelating trace element liquid fertilizer. All kinds
of lignosulfonate microfertilizer are recommended for drip
irrigation or foliar fertilization, with non-plant toxicity,
application safety, fertilizer effect is equivalent to 2~3 times
inorganic microfertilizer. Lignosulfonate microfertilizer can also
be concentrated into dry powder mixed into granular fertilizer, or
on the surface of major granular fertilizer spraying lignosulfonate
microfertilizer.
After application on acidic soil, the content of residual ammonium
nitrogen in soil was much higher than that in control soil,
indicating that lignosulfonate chelated micro-fertilizer could also
reduce the loss of fertilizer nitrogen. It was also found that the
degree of soil acidification was low, the soil salinity decreased,
the available phosphorus, available potassium and organic matter
were increased to a certain extent, and the soil fertility was
enhanced, which was conducive to the sustainable development of
agricultural ecology.
