For what, it's recommended to use granular fertilizers?
For planting crops which depend in watering by rainfall
For poor, sandy, and saline soil
For planting in heavy rains climate
For planting without continuous irrigation
For economical reason and cost saving
Using of granular fertilizers based on release time:
Slow Release Granular used in heavy rain climate
used in crops which need high watering rates
used in long shelf life crops
used in soil which contain high organic matter and other nutrients
Fast release granules
used in limited rains climate
used in limited water case
used in short shelf life crop
used in poor soil
Mixed release granular type is granular contain 1 or 2 nutrients slow or fast release in action
Most important products
(1) Granular minor elements which contain single minor elements or contain mix of many minor elements
Example: Granular Booster
(8%MgO + 3%Zn + 3%Mn + 3%Fe + 10%Organic Matter)
Used to break dormancy and activate the biological and enzymatic system in plants and trees
(2) Granular Salinity corrector
(12%CaO + 4%MgO + 9%S + 20%Organic Matter)
Used to reduce salinity of soil and before flowering stage in trees
(3) Customized granular products based on technical needs or certain uses of client and importer
(4) Granular products range very rich in SiO2 (Silica)
Benefits of Silica (Si) for plants:
(A) Resistance to disease and pest
Si provide physical barrier to pathogens and insect, due to Si deposition on the epidermis tissue
(B) Cell structure
Increase the mechanical stability of the plant and reduce the incident of lodging, due to Si accumulation in tissue
(C) Increase and regulate uptake of other nutrients
(D) Resistance of stress
Transpiration rate reduction due to heat stress
Reduce salt stress by inhibiting Sodium uptake
Crops in which Si work:
Rice Cotton Sugar Cane Potato Banana Turf
Vegetables: Tomato, strawberry, onion, Cucurbit
Fruit Trees: Avocado, pomegranate, Date Palm, ….
Main SiO2 Granular products:
Granular Complex (10%K2O + 7%CaO + 1.5%MgO + 45%SiO2)
Granular SilFe (15%Fe + 44%SiO2)
Granular Minor Elements Mix (Fe, Zn, Mn, Cu, B, MgO, CaO, Mo, ….) + 40%SiO2
And many other customized Granular formulas based on importer request:
(N + Si) (NP + Si) (PK + Si) (CaO + MgO + Si) …….
