Water-Retention Humic Acid Powder for Date Palm in Arid Soil
Huayuan water-retention humic acid powder is engineered for arid agriculture in Saudi Arabia and the Gulf region, where coarse sandy soils lose irrigation water almost as fast as it is applied. The high-carbon, sponge-like structure of humic acid holds moisture and dissolved nutrients in the root zone, helping date palm growers stretch every litre of water and build fertile soil where none existed before.
Key Features
- Exceptional Water Retention: Increases the water-holding capacity of sandy soil, extending irrigation intervals and reducing water bills in desert farming.
- Sandy Soil Improvement: Binds loose sand particles into stable aggregates, reducing deep percolation and giving roots a firmer growing medium.
- Date Palm Optimized: Supports deeper root development and better nutrient uptake in date palm plantations, improving frond health and fruit set.
- Salinity Tolerance Support: Buffers the effects of saline irrigation water by improving CEC and soil buffering capacity in desert conditions.
- Easy Irrigation Application: Dissolves readily for drip and bubbler systems, or can be mixed into planting pits and topsoil during establishment.

Applications
Apply 15-30 kg per hectare through drip irrigation monthly during the growing season, or broadcast 300-600 kg per hectare and incorporate into the top 20 cm of sandy soil before planting. For established date palms, apply in a ring around the drip line and irrigate thoroughly. Repeat annually to progressively raise organic matter and water-use efficiency in arid production systems.
