Increased agricultural production can be achieved through appropriate technology approach, among others, by applying a balanced fertilizer technology specific location. Currently, the recommended fertilization technology is hardly practiced by most of Indonesian farmers, causing fertilization becomes unbalanced. The low knowledge of the importance of garden soil fertility data and carrying capacity of the plant nutrients for growth and production is characterized by low levels of productivity compared to crop genetics.

In support of balanced fertilization method can be performed using several types of single nutrients that are mixed in a simple ( simple blending) , or mixed mechanically ( mechanical blending) or by chemically mixing technology ( chemical blending) called compound fertilizer with nutrient composition or certain formula. While site-specific fertilization is approached by reading secondary data map of soil fertility in a region followed by listening to customer information will condition the garden. Information about the condition of crops farmers can also visually provide basic data for calculation of nutrient composition for preparing a fertilizer that will be manufactured at the factory.

Gramalet® Kopi as fertilizer formulating specific for Coffee plant. Its contains complete nutrient ingredient such as macro- nutrient NPK ( Nitrogen, Phosphorus, Kalium / Potassium) , secondary nutrient MgSCa ( Magnecium, Sulfur , Calcium) and micro- essential nutrient ( Zn, B, Bo, Mo, Cl, Mn, Fe) with formula composition per each nutrient 19-10-15-3-4-2 + 1 ( micro element) . The formula registered at Ministry of Agriculture Republic Indonesia, Number : 905/ BSP/ II/ 2003.

Complete nutrient content, which as tablet appereance former on 10 gram for coffee planting fertilizing use - as same as with 35 % than single fertilizer totally amount usually using such as Urea, Phosphorus, Kalium/ Potassium. Tablet appereance which diameter ( 25 ± 2) mm, height 15 ± 2 mm and grayish-white colour make eficiency increasingly.

For example, 1 ( one) ha use 150 kg/ ha/ year. Gramalet Kopi ( coffee fertilizer specific ) makes efficiency increasing and furthermore could grow up the farmer or estate company income.

Quality Standard of complete granular compound tablets, Gramalet among others:

1) . nutrient fertilizer containing at least 3 primary macro nutrients ( Nitrogen, Phosfat / K2O5 and Potassium K2O / NPK) , secondary macro nutrients ( magnesium or Kieserite / Mg, Sulfur / S and Calcium / Ca) and micro essential nutrient ( Fe, Cu, Zn, B, Bo, and molybdate / Mo) ,

2) . tablet form - the result of the integration of physics at a certain pressure / cm 2 so that the unification of nutrients is solid and compact, capable of removing nutrients in a controlled ( slow release)

3) are presented from selected raw materials such as urea, Super phosfat ( SP) and KCL and the sources of Mg and Ca from Kieserite ( MgCaO) Ex China or Germany - which has advantages such as the level of water soluble ( solubility in water that absorbed by plants) is high and guaranteed not to be bound in a chelate compound ( which protects nutrients from water absorption) .

4) . contains important micro nutrient elements - including Mo ( molibdium) .

Gramalet NPKMg ® has a composition of S, Ca and micro elements ( Fe, B, Bo, Mo, Mn, Zn, Cl) using the following packaging specifications:

a) packaging in the ( inner packing) : Plastic PE 0, 8 to 1, water and air-tight containers, the capacity of 5 kg ( gross weight)

b) The outer packaging ( outer packing) made out of cardboard D / W: a) Size: ( 360 x 355 x 263) mm b) Type of cardboard: K 200 / 150 / K200 c) Capacity: 20 Kg.

With these specifications ensure packaging as transportation, storage and handling of inter-regional transport, including handling at the port becomes more secure, inexpensive and easy.
