ABSTRACT

The efficiency of the composting process for tomato residues and chicken manure was estimated after monitoring of the rotary composting system. Physicochemical parameters and Compost Quality Index were evaluated. The tomato residues (leaves, stems, and some green and damaged fruits) were collected, cut into small pieces, moistened approximately (60–65%), and mixed with 20% chicken manure then distributed into three rotary drum bioreactors. The obtained results showed that, the temperature above 50 °C was maintained for more than two days. Carbon: nitrogen (C:N) ratio was reduced from 30:1 to 19.13:1. The pH value ranged between 7 and 8.80 during the composting process, while the electrical conductivity (EC) ranged between 2.67 to 4.53 dS/m. Both compost quality parameters (Dewar and germination index) and (Solvita-CO₂ and Solvita-NH₃) indicated that, the final compost is stable and mature.

Implication statement

The idea of ​​this research revolves around assessing the maturity and stability of the compost resulting from mixing tomato residues with chicken manure, using a rotary drum bioreactor which is characterized by reducing the time of the active phase to several hours or days instead of weeks or months. Several tests related to the maturity and stability of mixture have been used to judge its quality. Also, many parameters related to this topic were monitored and discussed with many previous researches to determine the importance of benefiting from mixing the different wastes together and obtaining a good fertilizer ready for application as an agricultural substrate or a soil conditioner.

摘要

在监测旋转堆肥系统后，估计了番茄残留物和鸡粪堆肥过程的效率。评价了理化参数和堆肥质量指数。收集番茄残留物（叶子，茎和一些绿色的和受损的水果），切成小块，弄湿约60％至65％，然后与20％的鸡粪混合，然后分配到三个转鼓式生物反应器中。所得结果表明，高于50℃的温度保持超过两天。碳：氮（C：N）比从30：1降低到19.13：1。在堆肥过程中，pH值在7至8.80之间，而电导率（EC）在2.67至4.53 dS / m之间。堆肥质量参数（杜瓦和发芽指数）和（Solvita-CO ₂和Solvita-NH ₃）表明，最终的堆肥是稳定和成熟的。

隐含声明

这项研究的想法围绕使用转鼓式生物反应器来评估将番茄残留物与鸡粪混合而产生的堆肥的成熟度和稳定性，其特征在于将活性相的时间减少至数小时或数天而不是数周或几个月。与混合物的成熟度和稳定性有关的一些测试已用于判断其质量。此外，与该主题相关的许多参数受到监视和讨论，并与许多先前的研究进行了讨论，以确定从不同的废物混合在一起并获得准备用作农业基质或土壤改良剂的优质肥料中受益的重要性。
