Most Metropolitan nowadays has many large cities scattered throughout the province. Magnificent and towering buildings that are characteristic of a city. Urban communities continue to grow as the birth rate explodes. Population migration is also another factor in increasing urban population.
The extent of urban land does not help in agriculture because it will be allocated in urban development. Every year, vacant land for farming activities decreases due to the large impact of city buildings. This causes the number of farmers in most countries to decrease due to the loss of agricultural land. However, we must look at these problems by presenting new solutions. Urban farming is an agricultural technique in urban areas and can be a solution to these problems.
Urban farming is an agricultural technique suitable for use in urban areas. Utilizing existing areas and not requiring large areas is one of the uniqueness of this agricultural concept. Urban farming is suitable for planting various types of vegetables such as mustard greens, broccoli, lettuce, onions, carrots, potatoes, and all types of vegetables available. Urban farming can not only be applied by farmers but also people living in cities. The quality of freshness that is of more value than this farming technique is because it is planted in one’s own home and immediately picked to be processed into food ingredients.
Of course the use of organic materials in the process of urban farming activities is very necessary because it keeps the quality of production safe for consumption, for example in the use of organic fertilizers and natural pesticides. Urban farming in its application has several types, namely verticulture, hydroponics, aquaponics, and wall gardening.
Verticulture is a vertical farming technique by arranging plants from the bottom up. Vertical technique is very suitable to be applied in a narrow area and not too wide. Actually, this technique is the same as conventional planting in general, which is using soil as a planting medium. Vertical laying that distinguishes verticultural techniques from other conventional farming techniques. Planting media containers can be used from materials that are easily found such as unused bottles (used bottles), paralon pipes, pots, polybags or other containers.Hydroponics is a technique of farming without using soil as a planting medium. The planting media used can be charcoal, husks, sand, brick fragments, and others. The main ingredient of hydroponics is water.
Hydroponics is very dependent on water as a nutrient fulfillment in plants. Fulfillment of plant nutrients in hydroponics can be given in the form of nutrients containing nutrients needed by plants. The planting media used is usually used plastic bottles or paralon pipes. Of course hydroponics can be placed in any area because it is easy to move and does not require a large area. Aquaponik is a cultivation technique that is combined with aquaculture such as fish. In this technique, the fish feces that are released will be used by plants as fertilizer to meet their nutrients. The place to hold fish becomes clean from dirt. Aquaponics establishes mutualism … Read More
