To total amount a farmer spends would then be Ksh 27,060 to be able to supply the right amounts of nitrogen for a harvest of 30 bags an acre. For C.A.N to supply 160 kilos of nitrogen to the maize crop, a farmer needs 615 kgs of the fertilizer which retails at Ksh 2200 per 50 kg bag. To complete the reaction it takes about 48 hours under the alkaline conditions. : +41 71 394 63 63Fax: +41 71 394 64 64, Nitrogen determination in urea according to the Kjeldahl Method, We use cookies to provide a user-friendly experience. Maize is an integral component in the diet of a majority of Kenyans. By continuing to browse this site, you give permissions for cookies to be used. Therefore, the urea is put into the soil and not on the soil to conserve fertilizer nitrogen. latest Then divide the pounds of nitrogen by the area the bag states it will cover to get the pounds of nitrogen per 1,000 sq.

Nitrogen determination in urea according to the Kjeldahl Method Urea is a common source of nitrogen in all solid nitrogenous fertilizers and it is widely used as a nitrogen release fertilizer. To be able to withstand such attacks, a healthy crop alongside other control methods are important. special With the above, farmers can make the right decision on which fertilizer to use as a top-dress. nutrient. Urea interacts with the soil life web in complex ways. As indicated by the name C.A.N contains calcium and 24 - 28% nitrogen (Nitrate) depending on the manufacturer. 350 kgs of urea is required to supply an acre of maize with the needed 160 kgs of Nitrogen. A 50 kg bag of urea retails at a recommended retail price (rrp) of Ksh 3200. Urea fertilizer can provide only nitrogen, no phosphorus or potassium, so it’s primarily used for bloom growth and vertical height may not be desired. C.A.N stands for Calcium Ammonium Nitrate, a compound fertilizer. Guide to using urea as a crop fertilizer in Minnesota: How to apply urea and how much to use. Subscribe to our newsletter and stay updated on the offers! special characters and numbers. Compound fertilizers are fertilizers that have more than one type of element i.e. bag of fertilizer … Subscribe to our newsletter and stay updated on the latest developments and It is therefore recommended that farmers split the application at least twice: at knee height (The top of the maize reaching the knees of an adult) and when the maize tassles (male flower at the top forms). After the application of urea placed on the soil surface or plant it may loose from 50 % to 90 % of its nitrogen as ammonia if not protected. To be able to harvest 30 bags from an acre with Urea as the topdressing fertilizer, a farmer therefore needs to apply around 350 kgs of urea fertilizer. Urea is an inexpensive form of nitrogen fertilizer with an NPK (nitrogen-phosphorus-potassium) ratio of 46-0-0. This crop is usually under various threats like pests, currently fall armyworm and desert locusts, diseases and many diseases. The 26% means that for every 100 kilos of C.A.N 26% a farmer applies to the maize crop; 26 kilos of nitrogen are made available in the soil. In presence of soil moisture and enzyme, urea normally hydrolyzes and converts to ammonia and carbon dioxide. It is important that farmers remember that timing of the application is very important. Urea decomposes when applied to the soil due to the activity of the enzyme urease. Nitrogen from urea can be lost to the atmosphere if fertilizer Urea is produced on an industrial scale: In 2012, worldwide production capacity was approximately 184 million tonnes. How much does a farmer spend for either fertilizer? The standard crop-nutrient rating (NPK rating) of urea is 46-0-0. Your passowrd must have atleast 8 character with a mixture of capital 1.Urea To supply the crop with the much needed nitrogen using Urea, a farmer needs 350 kilos of the fertilizer. Here, the etermination of nitrogen in a urea sample used as a fertilizer is performed using the KjelDigester K-449 and KjelMaster System K-375 / K-376. Advantages of Urea Fertilizer * Highest nitrogen content. Too often farmers apply inorganic fertilizers based on guesswork and estimates. Urea is a common source of nitrogen in all solid nitrogenous fertilizers and it is widely used as a nitrogen release fertilizer. Therefore, it has very low transportation costs per unit nitrogen. A 50 kg bag of urea retails at a recommended retail price … The urea fertilizer, also popularly called forty six zero zero (46-0-0), is a simple or straight (single-element) fertilizer that supplies the major essential element nitrogen in ammonic form (NH 4 +).The positively charged ammonium ion (NH 4 +) is nonvolatile and is one of the two forms of nitrogen that can be absorbed by plants, the other being nitrate (NO 3-). Therefore, a farmer needs around 12.3 bags of C.A.N. Note: Fertilizer bags usually come in 5,000 or 10,000 sq. Scientists recommend 160kg of N (Nitrogen) for a good harvest, usually 30 bags from a single acre. BÜCHI Labortechnik AGMeierseggstrasse 40Postfach9230 FlawilSwitzerland, Tel. ft. For example: A 19 lb. To get 350 kgs a farmer needs to buy seven 50 kgs bags and spend Ksh 22,400 to purchase the required nitrogen amounts for a 30 bag harvest from an acre. 100 kg of urea = 46 kg of Nitrogen, therefore, how many kgs of Urea will supply 160 kgs of Nitrogen?

If a farmer plans to use 26% C.A.N for topdressing in two splits assuming that the soil has zero nutrients, for one acre 615 kgs of C.A.N is required. The reaction takes place after the urea is dissolved in water. It is important that a farmer understands the right amount as it saves on operational costs. developments and special offers!
