Coffee is an export commodity that was encouraging because it has relatively high economic value in domestic and world market, hence the coffee plant is one of the leading commodity. Indonesia became the world' s largest coffee producer after Brazil and Columbia.

In general, coffee plants require soil with a layer of deep, loose, fertile, many containing humus, and permeable, or in other words, the texture of the soil must be good. Soil texture / structure, both are soil derived from volcanic ash or which contain enough sand and organic. Such a rotation soil air and water in the ground goes well, do not want a shallow ground water, because it can rot roots, ground water depth of at least 3 meters from the surface. The roots of coffee plants require high oxygen, which means less good soil drainage and heavy clay is not suitable. Because unless the land is difficult to penetrate the roots, water and air circulation becomes bad. Similarly, heavy sand soil, in general, the moisture capacity is less, because less able to bind water.

In general, the coffee production in Indonesia is still low, at an average of 700 kg / ha / year, or only reached 60% of potential productivity. Efforts to improve the productivity of coffee, including by improving the quality of seeds, improved cultivation and processing, research and provision of fertilizer specific formula that is intended for the benefit of coffee plants grow and thrive. Efforts to improve productivity and quality coffee needs to be done, if given, is stable and its prospective price of coffee in the world market.

Fertiliz ation incorrect dose, time, and do not cause the plants to grow well and optimal. Plants to be deprived of nutrients and excess fertilizer. Similarly, on the contrary, excess fertilizer doses can cause an imbalance of nutrients in the soil, damaging soil properties, and environmental pollution. A good fertilization requires the availability of fertilizers that contain all the nutrients that plants need are available when needed according to crop growth stage. Type a complete fertilizer such specific fertilizer plants include Gramafix® .

Single fertilizer needs as recommendations related institutions coffee for the coffee plants at the age of 7 ( TM-5) , for example, 243 kg Urea + 216 kg and 241 kg of KCl SP will have equality with only 200 kg of fertilizer Gramafix ® Coffee. Examples of the coffee plant ( TM 5) , with a dose of 150 g / Phn / yr or 80 g / Phn / 6 months, can be created 4 dots or holes, burying each - each 2 tablet ( @ 10 g) per hole per 6 months. After the fertilizer embedded, the hole is closed again. It is recommended that at the time of fertilization, about grass roots clean from pests ( weeds) .

One effort to improve productivity in a sustainable coffee is to increase production by fertilizing tablets along with improving the condition of land with organic fertilizer. The use of organic fertilizer will have an impact not only can improve soil nutrient levels and productivity of coffee plants, also controls the parasitic nematode attack.

Organic manure compost can be made of agricultural waste in the form of ( residual crop residues) and waste agricultural industry. The application of organic compost with the introduction into the moat ( rorak) , size ( 100x40x40 cm) at a distance of 75 cm from the main plant. Events compost will help land the preferred coffee plants, among others, the top layer of deep, loose, fertile, many containing humus, and permeable.

Integrated use of fertilizer ( a combination of organic and inorganic fertilizers) will raise the present low productivity of 700 kg / ha / yr in order to achieve appropriate genetic yield potential can be up to 1, 500 kg / ha / yr * )
