The coffee plants’ nutritional needs fall within the planting and cultivation category and is one of the most important factors in improving the quality of coffee.

It is very important to use high quality fertilizers in the right proportions and the correct ingredients. Keep in mind when choosing your fertilizer that coffee trees seem to be chlorine sensitive and also susceptible to boron toxicity more than any other plant species. The fertilizer analysis is very crucial. The macronutrients are nitrogen, phosphorus, potassium, calcium, sulfur and magnesium. Other nutrients needed are iron, zinc, molybdenum & copper to name a few.

Soil sampling, tissue sampling and visual inspections are key to maintaining the proper nutrition. Applying the wrong fertilizer is a waste of time, labor and money and could also cause damage to the crop needless to say the ecosystem. Also remember that fillers are useless weight and the wrong composition may be detrimental.

Good Nutrition - 2 years Growth

Follow these general rules of thumb: Nitrogen is for vegetative growth, phosphorus is for root development and potassium is for fruit development and overall quality. Calcium is needed for proper structure and growth and magnesium for chlorophyll.

This is known as ‘the law of limiting factors’ simply meaning that when all the necessary factors are present and in correct balance except for one the growth of the plant is critically limited because of that one missing factor.
