Therefore, pure KCl is 39.09/(39.09 + 35.45) = 52% potassium and 48% chlorine by weight. Its K value is therefore 52/0.83 = 63; that is, a fertilizer that gets all its potassium from K 2 O and has the same potassium contents as pure KCl would have to be 63% K 2 O. Pure KCl fertilizer would thus be labeled 0-0-63.
Urea phosphate is a 1:1 combination of urea and phosphoric acid that is used as a fertilizer. It has an NPK formula of 17-44-0, [ 1 ] and is soluble in water, producing a strongly acidic solution. Urea phosphate is available in fertilizer vendor bags that carry a UP signet on the packaging.
The Philippines' Fertilizer and Pesticide Authority (Filipino: Pangasiwaan sa Pataba at Pestisidyo, abbreviated as FPA), is a technical regulatory agency under the Department of Agriculture. The agency is responsible for assuring adequate supply of fertilizer and pesticide at reasonable prices; rationalizing the manufacture and marketing of ...
The idea appealed to the Government of India and eminent cooperators of the country. As a result, Indian Farmers Fertilizer Cooperative Limited (IFFCO) was conceived and registered on 3 November 1967, as a multi-unit cooperative society with the primary objective of production and distribution of fertilizers.
[23] Eutrophication of rivers, lakes and the sea has a very well-documented link to increasing phosphate concentrations. However, teasing out the contribution made to this problem by the use of superphosphate is difficult because of the wide range of other sources of phosphorus compounds in both human and animal waste streams.
Ammonium nitrate is an important fertilizer with NPK rating 34-0-0 (34% nitrogen). [17] It is less concentrated than urea (46-0-0), giving ammonium nitrate a slight transportation disadvantage. Ammonium nitrate's advantage over urea is that it is more stable and does not rapidly lose nitrogen to the atmosphere.
The International Fertilizer Association (IFA) promotes the efficient and responsible production, distribution and use of plant nutrients to enable sustainable agricultural systems. IFA a membership consists of more than 400 entities from producers through traders and distributors, as well as service providers, research organizations, tech ...
In 1986, a master's thesis study in the Philippines compared the effects of using various fertilizers to enhance milkfish production in brackish water ponds. [7] The study compared the use of using chicken manure only, cow manure only, 16-20-0 fertilizer only, a mixture of cow manure and 16-20-0 fertilizer, a mixture of chicken manure and 16-20-0 fertilizer, and a control group that used no ...
