Saudi Date Palm Saline Irrigation Water Humic Acid Powder 85% High EC Tolerance Desert Grade

Date palm is one of the few crops in the Gulf that can still be farmed at 5 dS/m, but it pays for it. In the Qassim and Al-Ahsa blocks we work with, irrigation water runs 4 to 6 dS/m, soil pH sits above 8.2, and the free calcium carbonate is often 25-35%. Under those three conditions micronutrients are effectively locked, sodium accumulates on the exchange complex, and the palm shows the classic K/Mg imbalance that shows up later as poor fruit fill and tip burn. An 85% humic acid powder with a CEC of 450-600 meq/100g gives the soil something to hold cations on other than sodium.

The grade is fully soluble, so it can go through the bubbler or drip line that most modern Saudi date farms now use, or be applied as a drench in the basin for older flood-irrigated blocks. Dosing is 40-80 g per palm, two to three times a season: once before flowering, once at fruit set, once after harvest with the leaching irrigation. At those rates a hectare of 156 palms uses roughly 6-12 kg per pass, which is small enough that the cost per palm is well under a riyal per application.

What we do not claim is that it removes salt. Nothing removes salt except drainage and leaching. What it does is keep the plant functioning under salt load: better aggregate structure so the leaching fraction actually moves through instead of ponding, higher exchange capacity to buffer sodium, and improved micronutrient availability in a calcareous soil. Farms using it typically cut the visible salt-stress leaf burn within one season and report better fruit size uniformity at harvest.

• 450-600 meq/100g cation exchange capacity: Provides exchange sites that would otherwise be occupied by sodium, buffering the root zone under saline irrigation
• Effective in calcareous soil above pH 8: Humic and fulvic fractions complex iron and zinc and keep them plant available where free carbonate would otherwise lock them
• 99% soluble for bubbler and drip: Dissolves cleanly for the irrigation systems standard on modern Saudi date farms, no basin-only limitation
• Water saving through structure: Improved aggregate stability lifts infiltration so the 15-20% leaching fraction needed at 5 dS/m actually passes the profile
• Low dose per palm: 40-80 g per palm per application keeps the per-hectare cost modest even at export powder prices
• Batch heavy metal screening: Tested against Gulf and EU limits, report issued with each COA

Apply 40-80 g per palm in the basin or through the drip/bubbler line, two to three times per season: pre-flowering, fruit set, and post-harvest with the leaching irrigation. For flood-irrigated older blocks, broadcast in the basin and irrigate immediately. For intercropped forage or vegetable plots under the palms, use 20-30 kg per hectare with the irrigation water.

Under 5-6 dS/m water, always pair the application with a proper leaching fraction of 15-20%. Applying humic acid without leaching in a saline block will not help, because the salt has to leave the profile. Do not mix the concentrate with calcium nitrate in the same tank; apply on separate days.

Packed in 25kg multiwall bags with PE liner, 40 bags per pallet, and 1 ton jumbo bags for farm-scale mixing. Neutral bags or private label printing with Arabic and English panels are available for distributors in Riyadh and Jeddah. Store under cover on pallets; hygroscopic powder, keep the bag sealed after opening.

Each batch ships with a COA covering humic acid, solubility, CEC, moisture, pH and a heavy metal panel (Cd, Pb, As, Hg, Cr). A sealed retained sample is kept 24 months. For distributor tenders we can arrange SGS or BV inspection at Qingdao before loading, and provide a pre-shipment sample with the batch code marked so your laboratory can verify on arrival.
