Sandy-Soil Humic Acid Granule Improves Water Retention Date Palm Arid Agriculture
Huayuan sandy-soil humic acid granules are formulated to tackle the two biggest challenges of arid agriculture in Saudi Arabia and the Gulf region: poor water retention and low organic matter. In coarse sandy soils, water and nutrients drain away before plant roots can absorb them. The sponge-like structure and high CEC of humic acid reverse this problem, making every litre of irrigation water work harder for date palms, fodder crops and greenhouse vegetables.
Key Features
- Sandy Soil Improvement: humic acid binds loose sand particles into stable aggregates, reducing leaching and giving roots a firmer, more fertile growing medium.
- Exceptional Water Retention: the granules hold several times their weight in water, extending irrigation intervals and protecting date palms in hot, arid climates.
- Date Palm Optimised: supports deeper root development and improved nutrient uptake in date palm plantations, contributing to healthier fronds and better fruit set.
- Salinity Tolerance Support: by improving CEC and buffering capacity, humic acid helps mitigate the effects of saline irrigation water common in desert agriculture.
- Heat-Stable Granular Form: free-flowing 2-4 mm granules remain stable and easy to apply even under high desert temperatures and low humidity.

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