Differences in fertilizer placement, cropping systems and soil reactions may favor one source over the other in specific locations. • MAP NH 3 +H 3PO 4 NH 4H2PO 4 • DAP 2NH 3 +H 3PO 4 (NH4) 2HPO4 To clear the air, a simple test called phosphate fixation capacity can indicate whether the soil requires phosphorus fertilisation every season. The composition of DAP is N-18% and P 2 O 5 -46%. Ammonium. 100g of DAP→46g of P Xg of DAP →1g of P Bulk density 0.9 tonnes per cubic metre. (12-4-8). DAP (diammonium phosphate), which is labeled 18-46-0, is an example of a complex fertilizer that’s mixed using a chemical reaction. The ratio of ammonia (NH3) to phosphoric acid (H3PO4) determines which product, monoammonium phosphate (MAP) or diammonium phosphate (DAP), is produced. For sowing there is little risk of affecting germination, even at high rates. Therefore, the elemental phosphorus percentage of a fertilizer is 0.436 times its P value. Packaging Type: Bag. At NCPB farmers were were to buy the subsidised DAP fertilizer at Sh1,200 per 50kg bag but farmers fear that the price may go as high as sh 3,000. The analysis or grade on a fertilizer label gives the ratio of each macronutrient in the product, represented by a 3-number ratio .

Any activity or operation carried out during the process of crop production has economic importance; fertilizer application is not left out. During the current crop season there has been an outcry from farmers in Rift Valley over fertiliser supply, availability, quality and type.

A granular, slow-release citrus fertilizer with this N-P-K ratio would be applied at a rate of 1/2 ounce per square foot under mature, outdoor trees every three months during the growing season. In fact, this is the fertiliser that was used during planting of cereals in the 1970s until our soils became depleted of organic matter that led to low soil nitrogen. Covering with a tarp may reduce any moist air uptake. The use of augers may damage the fertiliser and increase any handling problems. Six crops (rice, wheat, cotton, sugar cane, rapeseed and mustard) consume about two-thirds of the fertilizer applied.

In applying the recommended amount of P in a drill-row or pop-up fertilizer placement, DAP will contain approximately 60 percent more N, which may be a potential injury risk. It can manufacture NPK … The ratio of ammonia (NH 3) to phosphoric acid (H 3PO 4) determines which product, monoammonium phosphate (MAP) or diammonium phosphate (DAP), is produced. The following table summarizes the difference between MAP and DAP fertilizer. They are applied when the crop is vigorously growing and on moist soil. When applying DAP, the fertiliser should be banded 5cm away from the seed, either below or to the side. This is ideal for a variety of plants, including palms and hibiscus. Although the phosphorus content is relatively low the presence of calcium and sulphur makes it valuable for our soils that have very little organic matter. Lawn Grasses grow the best on a nutrient ratio of 3 parts nitrogen, 1 part phosphorus, and 2 parts of potassium.
