Like human beings, plants too need the right kind and amount of food for their growth and development. But unlike man, plants cannot move around to collect their food. They have to synthesize their own food. To synthesize their food, plants require nutrients in addition to light, heat, air and water. Organic fertilizer is used to produce the tasteful crops. It will help to produce the balanced ammo.
Organic fertilizers also called natural fertilizer is a fertilizer that is composed / made from living material, such as weathering the remains of plants, animals (cows, buffaloes, goats, chickens, etc.). Organic fertilizers can be either solid or liquid form that is used to improve the physical properties of soil, chemical, and biological organic tanah.Pupuk contain a lot of organic material than haranya levels (N, p, k).
Sources of Organic Material
Can be compost, green manure, farmyard manure, the rest of the crop, livestock waste, industrial wastewater using agricultural materials, and municipal waste.
History of fertilizer use is basically a part of the history of agriculture. Fertilizer use is estimated to have started since the beginning of known human cultivation, which is about 4500-5000 years ago. Agricultural lands are located around the river flows are very fertile due to receive the nutrient rich silt over the flooding that occurs every year. In Indonesia, an organic fertilizer has long been known to the farmers. Indonesia's population are familiar with organic fertilizers before application of the green revolution in Indonesia. After the green revolution, most farmers prefer to use artificial fertilizers / chemicals for practical use, the number is much less than organic fertilizers, Harganyapun relatively inexpensive, and easily obtained. Most farmers are very dependent on artificial fertilizers, which can negatively impact the development of agricultural production. Growing awareness of the farmers would negatively impact the use of chemical fertilizers and other modern means of agriculture on the environment has made them switch from conventional farming to organic farming.
Fertilizer Types Organic / Natural
1. Manure / animal feces
*. Liquid fertilizer / cold is a fertilizer derived from animal waste is described by mikroorganime slowly so as not to generate heat, such as manure from cow dung, buffalo, and pigs.
*. Solid manure / fertilizer heat is derived from animal waste are described microorganisms rapidly, giving rise to heat, such as fertilizer from goat manure, horse and chicken2. Green manure / leaf remaining
