Compost production through the aerated static pile method

Resumen

Objective: To evaluate and validate the method of compost production by aerated static piles (ASP), in comparison with a traditional method to optimize the composting process.

Design/methodology/approach: The static pile system (ASP) was designed and established for compost production at the Huimanguillo Experimental Field (Tabasco, Mexico), where composts of different manures were used in a completely randomized experimental design to evaluate nutritional and quality parameters of the composts to compare with the traditional method.

Results: It was found that the ASP method allows obtaining composts with higher nutritive values than those generated by the traditional method. In addition, it satisfies the required quality.

Limitations of the study/implications: It is suggested to study more doses of the composts generated by ASP in different crops and stages.

Findings/conclusions: The ASP method by injecting more air during the composting process, raises microbial activity, which in turn, raises compost temperatures, achieving higher fixation of nutrient compounds
