DAP Fertilizer in Kenya
Di-ammonium Phosphate – DAP Fertilizer in Kenya
DAP fertilizer is an excellent source of P and nitrogen (N) for plant nutrition. It is very soluble and therefore dissolves quickly in the soil to release the phosphate and ammonium available to plants. A notable property of DAP is the alkaline pH that develops around the dissolving granule.
As dissolved DAP granules release ammonia, seedlings and plant roots closest to the volatile ammonia can be damaged. This potential damage most often occurs when soil pH is above 7, a condition that often exists around dissolving DAP granules. To avoid such damage, users should avoid placing high concentrations of DAP near germinating seeds.
The ammonium present in DAP is an excellent source of nitrogen and soil bacteria will gradually convert it to nitrate, which will cause the pH to drop even further. Therefore, the increase in soil pH around the DAP granules is a temporary effect. This initial increase in soil pH near the DAP can influence the microsite reactions of phosphate and soil organic matter.
Diammonium phosphate (DAP) is a granular field fertilizer with 18% N and 46% P2O5 used on a variety of crops, especially seeds, to ensure a strong root system and a good start.
Plants need light, moisture and nutrients to grow. The sun brings light. Moisture comes from rain or irrigation. Nutrients come from fertilizers, compost or manure.
If the plants are not growing well, fertilizing them will only help if a lack of nutrients is the cause of the problem. Plants growing in poorly drained soil, excessive shade, or in competition with tree roots do not respond to fertilizers.
Fertilizers are either organic or inorganic. Examples of organic fertilizers include manure (poultry, cows, or horses), bone meal, cottonseed, or other natural materials. Inorganic fertilizers are artificial products. They tend to have a higher nutrient content.
What Is the Proportion Of DAP Fertilizer -DAP Fertilizer in Kenya
• This type of ammonium phosphate compound is readily available in the soil, is not easy to leach out and is therefore easy for plants to absorb.
• It is Universal – it can be applied to all crops (Cereals, Vegetables and Fruits).
• This form of phosphorus is easily assimilated by the soil, even in the event of a water shortage.
• With this composite formulation, the excessive absorption of potassium is limited.
Standard application rate: 50-75 kg/acre (soil testing is however recommended).
Composition: 18% N, 46% P2O5.
How Long Does DAP Last In Soil - DAP Fertilizer in Kenya
Diammonium phosphorus (DAP) use is best targeted as an initial fertilizer application. This technology targets the emerging roots of seedlings. For this reason, the streaming application would not optimize the hardware and this streaming approach would not be recommended. This is because it requires much higher fees and has more issues. Instead of the fertilizer recommendation, the initial fertilizer recommendation would be to use DAP as a seed strip application, placing a fertilizer strip treatment 6 cm next to the seed row and 6 cm below the row. of seeds.
This starter strip avoids the toxicity of ammonium and prevents the phosphorus contained from being immobilized or fixed in the soil. With this approach, a DAP application of 100 kg/ha would provide the total phosphorus needed for aggressive root growth and supply the nitrogen requirements until a crop like maize reaches knee height. This approach can significantly reduce the total amount of fertilizer applied.
Using a nitrogen application in the last season as an application would optimize the nitrogen and help eliminate weed problems. A target application of 80 kg N per hectare would give near optimal yield based on phosphorus and nitrogen requirements, providing a much lower total fertilizer application and reducing environmental impact and cost. Using a broadcast fertilization approach would require 2-3 times the application of fertilizer. When working on your fertility program, perform a soil test to see what nutrients may be low or high in your soil so the soil program can be tailored to soil conditions and crop needs.
How Much DAP Per Plant - DAP Fertilizer in Kenya
First calculate the dose of DAP fertilizers (which contains 46 % P2O5 and 18 % N) to provide P2O5 in 2000 meter square area (0.2 hectare) @50 kg P2O5/ ha...
(50 kg/ha×0.2 ha)×100/46= 21.74 kg DAP is required...
Now see, how much nitrogen will be provided by 21.74 kg DAP as DAP contain nitrogen also that is 18 %
100 kg DAP will provide 18 kg N
then 21.74 kg DAP will provide 18×21.74/100= 3.91 kg N...
Requirement of nitrogen is 50 kg/ha...
Then remaining amount of nitrogen that is 50-3.91= approximately 46.09 kg N will be supplied by using urea (contain 46 % N)....
Amount of urea required to supply 46.09 kg N
(46.09 kg/ha × 0.2 ha)×100/46%= 20 kg urea...
Why DAP is Important - DAP Fertilizer in Kenya
Nitrogen
All parts of a plant need nitrogen to grow: roots, leaves, stems, flowers and fruits. Nitrogen gives plants their green color and is needed to form proteins. Lack of nitrogen causes the lower leaves to turn yellow and the whole plant turns pale green. On the other hand, too much nitrogen kills plants.
Phosphorus
Phosphorus is necessary for cell division and the formation of roots, flowers and fruits. Phosphorus deficiency causes stunted growth and poor flowering and fruiting.
Potassium
Plants need potassium for many chemical processes that allow them to live and grow. Potassium shortage manifests itself in many ways, but stunted growth and yellowing of the lower leaves are common symptoms in many plants.
When buying fertilizer, consider the cost per pound of nutrients. Generally, higher test fertilizers and larger containers are less expensive. For example, a 50 lb bag of 10-20-10 may not cost more than a 50 lb bag of 5-10-5 fertilizer, but the bag of 10-20-10 has twice the nutrients.

Advantages of DAP Fertilizer in Kenya
Soil Testing: For the productive use of this compost, the nitrogen and phosphorus content of the soil should be tested to decide the required DBH measurement.
Basal Dose: DAP is the most suitable compound for the basal portion, because through it we can apply a full portion of phosphorus and 33% half of nitrogen. The remaining dose of nitrogen can be applied through urea parts at different stages of harvest. Thus, DAP provides the best mix with urea manure. DAP is also the best manure for areas where less nitrogen and more phosphorus are needed as input.
DAP Position: Since phosphorus is stationary in the soil, its source (DAP) should be placed far away where plant roots can reach without too much stretch. Improper use of DAP can damage seedlings due to the influx of alkali. The DAP should be placed under the seed, slightly to the side.
Soil Amendments: Nitrogen and phosphorus work best in nonpartisan soils. However, if basic volatilization occurs, the problems with aromatic salts are greater. Therefore, the efficiency of nitrogen utilization is reduced. The corresponding unnecessary presence of calcium in base soils leads to buildings being constructed with phosphorus and ultimately causes unfortunate phosphorus recovery. Therefore, bringing the soil pH to a nonpartisan level by adding gypsum and drainage can further develop the effectiveness of DAP in utilizing N and P.
Disadvantages of DAP Fertilizer in Kenya
Over-fertilization is a significant and normal problem for phosphate fertilizers. Many gardeners mistakenly add phosphate fertilizers to soils they believe are low in phosphorus when nitrogen deficiencies are a much more common reason for the side effects of lack of supplementation on plants. In these cases, the excess phosphorus in the soil not only does not determine the problem of lack of supplementation, but can aggravate the situation, causing leaf chlorosis and damaging the beneficial microorganisms that live in the soil.
Another significant disadvantage of phosphate fertilizers is the high likelihood of water contamination. Phosphorus that enters the soil through phosphate manure and binds tightly to soil particles is unlikely to leave the soil. However, if a large amount of phosphate manure is applied to the soil, the excess phosphorus can easily reach water systems through storm surges and pipelines. Grass clippings and leaves of plants that have grown in soils with excess phosphorus will contribute their phosphorus to the water, promoting green growth and the emergence of microorganisms and water pollution problems.
