Term Organic Fertilizer
Definition

Stable and degraded organic matter that is added to the soil to provide physical, biological and chemical traits favorable to plants. It is prepared through the transformation of organic animal or vegetable waste from crop remnants, organic waste from mixed farming (such as farmyard dung and chicken manure) or remnants from the processing of agricultural and household waste such as garbage from homes or excrement, etc. Some of the different organic fertilizers include composting, Bokashi, earthworm humus, manure and green fertilizers. Environmental conditions, management, the types of materials used in their preparation and the differing production processes result in differences in the nutritional content and the microbiological population of each type of organic fertilizer.

In the past 10 years, the heightened demand for food, coupled with the high cost of inorganic fertilizers and the need to reduce the amount of chemicals applied to crops has caused an increase in the use of organic fertilizers in the Dominican Republic. However, there are still no regulations governing their production and use.

The most widely used organic fertilizers in the country are Bokashi, composting and earthworm humus, produced on farms and by manufacturing companies in Jarabacoa, Espaillat, La Vega and Monte Cristi. The primary raw materials used for their production include manure from chicken and other fowl, manure from cattle, goats and sheep, coffee pulp, crop residues and forest soil.¹
