CRF's - The Most Technically Advanced Method of Supplying Nutrients to Crops

Controlled Release Fertilizer (CRF) is a granulated fertilizer that releases nutrients gradually into the soil, with a controlled release period. The gradualness of the release depends on low solubility of chemical compounds in the soil moisture. Since conventional fertilizers are soluble in water, the nutrients disperse quickly, as the fertilizer dissolves. But controlled-release fertilizers are not water-soluble, the nutrients disperse into the soil slowly, giving time for the crops to absorb the nutrients. Hence, improving the yield.

FISH FARMING; A MONEY SPINNING AGRIBUSIESS

BACKGROUND Fish is an important source of food, income, employment, and recreation for people around the world and it is very important source of animal protein for both man and livestock in developed and developing countries. Humans consume approximately 80% of the catch as food. The remaining 20% goes into the manufacturing of products such as fish oil, fertilizers and animal feed (FAO, 2015). Fisheries and aquaculture are integral part of Agriculture which were found to have the capacity to increase the country's GDP (Gross Domestic Product), employment opportunities and also bring about financial uplift to individuals farmers involved. According to  the Intergovernmental Institute for Tropical Agriculture (IITA) in 2015, The demand for fish in Nigeria mostly outstrips the local production. Nigeria is the largest fish consumer in Africa, and among the highest fish consumers in the world. With over 1.5million tons consumed annually. Yet, Nigeria imports over 900,000metric ton...

HOW AGRIBUSINESS DIFFERS FROM THE CONVENTIONAL BUSINESS

Agribusiness is the business of agricultural production, an industry engaged in the producing operations of a farm, the manufacture and distribution of farm equipment and supplies, and the processing, storage, and distribution of farm commodities. The term was coined in 1957 by Goldberg and Davis. It includes agrichemicals, breeding , crop production ( farming and contract farming ), distribution, farm machinery ,processing, and seed supply, as well as marketing and retail sales. All agents of the food and fiber value chain and those institutions that influence it are part of the agribusiness system. Examples of Agribusiness Companies Deere & Company, which makes John Deere equipment, may be one of the best-known examples of a classic agribusiness company. The firm doesn't own farms or produce food products, but nearly every farmer owns a John Deere tractor, baler or some other piece of the quintessential green and gold farm equipment. Monsanto Company, which manufacture...

Genetically modified foods ; The myth and truth of the unending debate.

Man ever since creation has evolved and survived well chiefly because of his instinct for survival which has hitherto driven him towards knowledge and research to fulfil his basic needs;  Food, cloth and shelter and also to improve his environment and life generally. For centuries, there has been scientific researches and projects aim at improving and increasing food supply to meet the food demand of the ever increasing world population. Earlier researches aim at achieving this include selective breeding involving artificial and natural selection as well as mutation breeding. With more advancement in knowledge and scientific research, there was the development of the most recent method of plant and animal improvement; genetic engineering or generic modification which is the direct manipulation of an organism's genome using biotechnology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries t...
