Agriculture is the production of food and goods through farming. Agriculture was the key development that led to the rise of human civilization, with the husbandry of domesticated animals and plants (i.e. crops) creating food surpluses that enabled the development of more densely populated and stratified societies. The study of agriculture is known as agricultural science. Agriculture is also observed in certain species of ant and termite.[1][2] Agriculture encompasses a wide variety of specialties and techniques, including ways to expand the lands suitable for plant raising, by digging water-channels and other forms of irrigation. Cultivation of crops on arable land and the pastoral herding of livestock on rangeland remain at the foundation of agriculture. In the past century there has been increasing concern to identify and quantify various forms of agriculture. In the developed world the range usually extends between sustainable agriculture (e.g. permaculture or organic agriculture) and intensive farming (e.g. industrial agriculture). Modern agronomy, plant breeding, pesticides and fertilizers, and technological improvements have sharply increased yields from cultivation, and at the same time have caused widespread ecological damage and negative human health effects.[3] Selective breeding and modern practices in animal husbandry such as intensive pig farming (and similar practices applied to the chicken) have similarly increased the output of meat, but have raised concerns about animal cruelty and the health effects of the antibiotics, growth hormones, and other chemicals commonly used in industrial meat production.[4] The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials. In the 2000s, plants have been used to grow biofuels, biopharmaceuticals, bioplastics,[5] and pharmaceuticals.[6] Specific foods include cereals, vegetables, fruits, and meat. Fibers include cotton, wool, hemp, silk and flax. Raw materials include lumber and bamboo. Other useful materials are produced by plants, such as resins. Biofuels include methane from biomass, ethanol, and biodiesel. Cut flowers, nursery plants, tropical fish and birds for the pet trade are some of the ornamental products. In 2007, one third of the world’s workers were employed in agriculture. The services sector has overtaken agriculture as the economic sector employing the most people worldwide.[7] Despite the size of its workforce, agricultural production accounts for less than five percent of the gross world product (an aggregate of all gross domestic products). |

Selama ini para petani telah banyak memanfaatkan bahan organik sebagai pupuk dilahan pertanian, karena bahan tersebut merupakan bahan yang cepat melapuk. Salah satu contoh bahan organik yang digunakan antara lain kotoran hewan (sapi, kambing, ayam, dll) dan limbah pertanian. Dengan munculnya berbagai pupuk alternatif dan untuk menunjang pembangunan pertanian yang ramah lingkungan, maka scat ini digalakan pemanfaatan limbah pertanian sebagai bahan pembuatan pupuk organik, bahkan beberapa petani/swasta Pupuk | pupuk SP-36 | SP-36 | pupuk phospat | jual beli pupuk SP-36 | pupuk phosfat | distributor agen pupuk SP-36 | pupuk organik | pupuk P | pupuk super phospat |

Sistim ini ternyata menghasilkan volume tisik dan penerimaan petani yang lebih besar. Selain itu anjuran terhadap teknik bercocok tanam dengan cara pupuk organik didasari atas pertimbangan bahwa para petani di Papua pada umumnya belum menggunakan pupuk dan pestisida secara intensif. Penerapan sistim pupuk organik juga mempunyai aspek pelestarian lingkungan. Dalam teknik bercocok tanam ini dianjurkan pengolahan tanah ganda, pembuatan bedengan tinggi, penambahan pupuk kandang dan sistim tumpangsari. Karena ketersedian pupuk kandang masih terbatas maka dilakukan adaptasi dengan Pupuk | pupuk kompos | kompos | membuat kompos | jual beli pupuk kompos | pertanian papua | makalah pupuk | jurnal pupuk | budidaya pertanian | agronomi | pupuk organik |
