Safety and FAQ
Common questions
What the products are, how to use them, and what to expect.
What are LVHAN soil conditioners?
They are eco-friendly polymer products that are worked into the soil. Hydrophilic groups on the polymer bind water, and the long charged chains bind soil particles into aggregates. The result is soil that holds more water and nutrients and loses less to evaporation.
How much do I apply, and how?
A typical rate is 3 kg per mu, which is 45 kg/ha or about 40 lb/acre. On dry soils with poor water retention this can rise to 4 kg per mu (60 kg/ha, about 53 lb/acre). Apply in a band, broadcast and incorporate, or place in the planting hole. The product can be blended with seed or fertilizer and applied by machine.
How long does one application last?
At least three years for the soil conditioners. The agro-forestry water-retaining polymer stays active in soil for about 3–5 years when it is kept out of direct sunlight.
Is it safe for soil and groundwater?
The company's product literature describes the water-retaining polymer as non-toxic, odourless and harmless, and states that it does not pollute soil or groundwater. Safety data sheets will be posted here: [SDS / TDS FILES TO BE ADDED].
Can it be used with fertilizer?
Yes. The products tolerate saline-alkali conditions and are designed to be used together with fertilizer. Holding nutrients in the root zone is one of their main functions.
Does it replace irrigation or rain?
No. It stores water; it does not create it. After application, the soil still needs rain or irrigation to recharge. In long dry spells, water roughly every 25–30 days where irrigation is available.
Is it registered for sale in the United States?
