Bulk Blending Fertilizer
Bulk mixing
Instead of distributing fertilizers with a single nutrient separately or making use of multi-nutrient fertilizers manufactured at the factory (complex fertilizers), the farmer may wish to mix the fertilizers himself or use the services of one of the retailers with mixing units. This offers the opportunity to prepare special mixtures with proportions of nutrients to meet the specific needs of the farmer, suited to his own soils and crops. The fertilizers to be mixed must be compatible chemically and physically:
• Chemically, so that there is no gas loss or decreased availability or accumulation of nutrients due to chemical reactions
• For safety reasons, special care must be taken when mixing ammonium nitrate fertilizers with other materials, such as potassium chloride and trace elements. A risk assessment should be carried out to ensure that mixed products meet regulatory requirements with respect to composition and resistance to detonation and decomposition
• Input materials and mixed products must be handled and stored according to the agronomist’s guidelines for the storage, handling and transport of solid mineral fertilizers
• Non-compliant materials and waste must be treated as indicated and disposed of in landfills
Guidelines for the safe handling and use of non-compliant fertilizers and related materials for producers
• Physically, the mixed materials must have a similar granule size (usually 2 to 4 mm) and density to prevent segregation during transport and propagation.
Is it OK to mix fertilizers?
Answer: You can mix the fertilizers, assuming they are both made from similar materials. They need to be spread or sprayed together. However, you won’t get the benefits you are assuming. The numbers on a fertilizer package are always listed in the same order.
Plants use more nitrogen than any other nutrient when they are growing. Nitrogen regulates the growth of stems and leafy green foliage. Feeding your plants with a fertilizer high in nitrogen promotes rapid growth in leaves and stems.
Bulk Blending Fertilizer is defined as the mechanical mixing of two or more granular fertilizer materials to produce mixtures containing nitrogen (N), phosphorus (P), potassium (K) and other essential plant nutrients such as limestone filler, and occasionally small amounts of secondary nutrients and micronutrients are mixed together.
By other side some fertilizers should not be mixed together in one stock tank because an insoluble salt might form very quickly. An example for such incompatibility is mixing fertilizers that contain calcium with those that contain phosphate or sulphate.
Ammonium phosphates and super phosphates should not be mixed with lime, slag, rock phosphate or CAN. Potassium chloride and sulfate of potash can be mixed with most fertilizers, but mixtures of these fertilizers with urea and calcium ammonium nitrate should not be stored.
Fertiliser blending (bulk blending) is a technical process that offers a customised balance by adjusting fertiliser inputs to crop requirements. In the right proportion, the blend must provide: Major nutrients: nitrogen (N), phosphorus (P), potassium (K);
Fertilizer blending provides solution to farmers to have the correct ratio of nitrogen, phosphorous, potash, and micro nutrients. With increased use of soil analysis and scientific crop management, fertilizer blending is often the best solution to provide farmers exactly what their crops require.
What is the best fertilizer for root growth?
N-P-K Fertilizer
For example, a 3-20-20 fertilizer that contains 3 percent nitrogen, 20 percent phosphorus and 20 percent potassium encourages roots to grow strong and healthy. Keep the nitrogen content low, as it promotes leggy green growth at the expense of rooting, flowering and fruiting.
This is true for all grasses. For most grasses, watering deeper, but less frequently will is the number one way of stimulating deeper grass root growth. After watering the soil should be moist at 4 to 6 inches below the surface. These deeper soil depths will remain moist long after the surface has dried.
Chemical fertilizer can also feed composting, but continual use may throw soil chemistry out of balance and discourage microbes. … Compost and organic fertilizers can work together. The organic matter in compost sponges up the fertilizer nutrients until they are needed by plants.
To find the amount of Nitrogen
The first number is the amount of nitrogen (N), the second number is the amount of phosphate (P2O5) and the third number is the amount of potash (K2O). These three numbers represent the primary nutrients (nitrogen(N) – phosphorus(P) – potassium(K)).
To find the amount of nitrogen in a bag of fertilizer, you must calculate the pounds of nitrogen per 1,000 sq. ft. To calculate the pounds of nitrogen in a bag of fertilizer, multiply the weight of the bag by the percent nitrogen (this is the first number in the N-P-K designation on the front of the bag).
