Iron (II) for soil treatment is supplied by KIKI'S Industrial Chemicals as technical-grade Ferrous Sulphate Heptahydrate 98% Min (approx. 19.7% elemental Fe). It is an effective, economical soil acidifier and micronutrient amendment used across Kenyan flower farms, avocado orchards, and tea estates to rapidly correct iron chlorosis (interveinal yellowing) in high pH soils.
Iron (II) Sulphate Soil Treatment Agricultural Acidifier is an inorganic micronutrient fertilizer and soil conditioner (FeSO4.7H2O, CAS 7782-63-0) designed for horticultural and broadacre soil pH correction.

Iron (II) for Soil Treatment (98% Min FeSO4.7H2O, approx. 19.7% active Fe) is an agricultural soil amendment and micronutrient fertilizer that rapidly corrects lime-induced iron chlorosis (interveinal yellowing) and lowers soil pH in high-pH calcareous soils across East African flower farms, orchards, and tea estates.
Available Packaging
KIKI'S Industrial Chemicals supplies agricultural-grade Iron (II) Sulphate Heptahydrate 98% Min engineered specifically for soil treatment, fertigation systems, and foliar micronutrient feeding across Kenya and East Africa.
In commercial horticulture (cut flowers in Lake Naivasha and Mount Kenya), avocado orchards in Central Kenya, macadamia groves, tea plantations, and sports turf management, alkaline or calcareous soils (pH above 7.0) immobilize native iron, causing severe iron chlorosis characterized by distinctive yellowing between leaf veins while veins remain green.
Our agricultural technical grade provides readily soluble bivalent iron (Fe2+) and sulfate sulfur (approx. 11.5% S), delivering both immediate iron nutrition and localized root-zone acidification to unlock immobilized phosphorus and micronutrients.
When applied to soil, FeSO4.7H2O dissolves completely in soil moisture. The ferrous ion (Fe2+) is the specific ionic form preferred for direct root uptake. In the rhizosphere, oxidation and hydrolysis of ferrous iron release hydrogen ions: 4Fe2+ + O2 + 10H2O -> 4Fe(OH)3(s) + 8H+, creating micro-zones of acidity that neutralize free bicarbonates and dissolve calcium carbonate barriers.
Unlike synthetic synthetic chelates (such as EDDHA or EDTA), ferrous sulphate provides an economical, chloride-free, and sodium-free source of iron that will not elevate soil electrical conductivity (EC) or risk leaf margin burn when applied at recommended agronomic rates.
Commercial farms and agro-dealers can place orders by bag or pallet. We provide agronomic dosing guides, Certificate of Analysis, and direct-to-farm transport across Kenya.
Commercial Sectors
From high-altitude greenhouse floriculture in Naivasha to open-field grain farming across Uasin Gishu, agricultural productivity hinges on water chemistry, soil pH equilibrium, and clean post-harvest sanitization. KIKI'S supplies technical acids, calcium amendments, and irrigation line descalers that keep East African agribusiness growing consistently.
Compounding commercial livestock feed requires tight mineral precision and uncompromising biochemical purity. In animal nutrition, a half-percent variance in calcium bioavailability or moisture-induced fungal growth ruins feed conversion ratios. KIKI'S supplies essential mineral carriers, acidifiers, and feed-mill sanitizers trusted by East African millers.
Process Compatibility
Store in a dry farm chemical shed on wooden pallets. Do not store directly on bare soil or damp concrete floors.
Reseal inner plastic liners tightly after opening to prevent moisture absorption and ensure crystals remain free-flowing for spreaders and fertigation injectors.
Farm workers should wear protective gloves, safety glasses, and dust masks during dry broadcast spreading or dissolving into fertigation stock tanks.
Do not spray ferrous sulphate solutions onto concrete pathways, decorative stone, or greenhouses structures, as iron oxidation will cause permanent orange-brown rust stains.
Flush eyes with clean water for 15 minutes. Wash skin with soap and water. If ingested, drink clean water and seek medical advice.

COMMERCIAL & TECHNICAL GUIDANCE
Technical, regulatory, and supply guidance for Iron (II) for Soil Treatment (Agricultural Acidifier & Chlorosis Correction).
Iron chlorosis occurs predominantly in alkaline or calcareous soils (pH above 7.0) containing high free calcium carbonate. While iron may be abundant in the soil, the alkaline environment oxidizes it into insoluble ferric oxides that plant roots cannot absorb.
