Calcium Lignosulphonate is used for slow-release long-lasting
compound fertilizer
Calcium Lignosulphonate:
Due to the loss of nitrogen through volatilization, leaching and
denitrification, phosphorus fertilizer is easy to be fixed by A13+,
Fe3+, Ca2+ and Mg2+ in the soil, forming stable precipitation or
forming closed storage phosphorus with iron and aluminum oxides and
gradually losing its fertility. As a result, the utilization rate
of fertilizer application in the season is very low.
The slow-release properties of lignin can better maintain the
effectiveness of chemical fertilizer and release it slowly, which
is a good controlled release material of organic compound
fertilizer. When N, P, K fertilizer is mixed with lignin, the
lignin slowly releases nutrient elements through physical
adsorption and van der Waals force to form slow-release long-term
compound fertilizer.
Slow-release long-acting compound fertilizer is suitable for rice,
wheat, sorghum and other food crops, cotton, oil and other cash
crops, vegetables, fruits and other horticultural crops because of
the three elements of nitrogen, phosphorus and potassium, can be
used as base fertilizer, topdressing and other applications. This
kind of fertilizer has obvious effect of increasing yield, and
maintain certain fertilizer effect in 3~4 years, and has the effect
of reforming soil aggregate structure.
