Abstract

Recycling of organic wastes through vermicompost production reduces the waste disposal into the environment and avoids the overusage of chemical fertilizers. The purpose of this study is to compare the quality of the raw materials in produced Vermicompost (spent mushroom compost, potato waste and pomegranatemeal + Sawdust, Choppered Corn) and their combination in a completely randomized design. After preparing vermicompost, the parameters, i.e., electrical conductivity, pH, organic carbon content, the amount of nitrogen, phosphorus, potassium, organic carbon/nitrogen ratio are measured. the vermicompost production process leads to a significant reduction in C/N, EC and pH. The lowest C/N was related to the vermicompost which is obtained from treatment pomegranate meal + Sawdust + spent mashroom compost waste. The obtained Vermicomposts included higher amounts of nitrogen, phosphorus and potassiumin compare to the raw materials. The highest nitrogen content was related to spent mashroom compost + potato waste treatment. As a result, the production of vermicompost from organic wastes leads to an increase in the nutritional value of the fertilizer and eventually the fertility of the soil. In conclusion, the chemical fertilizers can be replaced as well, with the produced organic bio-fertilizer with the lowest cost.Thus problems associated by the use of chemical fertilizers, which today are one of the greatest environmental problems in the world, can be solved.

摘要

通过蚯蚓粪生产回收有机废物，减少了废物排放到环境中，避免了化肥的过度使用。本研究的目的是在完全随机的设计中比较生产的蚯蚓堆肥（用过的蘑菇堆肥、马铃薯废料和石榴粉 + 锯末、切碎的玉米）及其组合的原材料质量。蚯蚓堆肥制备完成后，测定电导率、pH值、有机碳含量、氮、磷、钾含量、有机碳/氮比等参数。蚯蚓堆肥生产过程导致 C/N、EC 和 pH 值显着降低。最低的 C/N 与从处理石榴粉 + 锯末 + 用过的蘑菇堆肥废物中获得的蚯蚓堆肥有关。与原材料相比，获得的蚯蚓堆肥包含更高量的氮、磷和钾。最高的氮含量与用过的蘑菇堆肥+马铃薯废物处理有关。因此，用有机废物生产蚯蚓堆肥会增加肥料的营养价值，并最终提高土壤的肥力。总而言之，化肥也可以被替代，生产出成本最低的有机生物肥料。因此可以解决使用化肥相关的问题，这是当今世界上最大的环境问题之一. 用有机废物生产蚯蚓粪会增加肥料的营养价值，并最终提高土壤的肥力。总而言之，化肥也可以被替代，生产出成本最低的有机生物肥料。因此可以解决使用化肥相关的问题，这是当今世界上最大的环境问题之一. 用有机废物生产蚯蚓粪会增加肥料的营养价值，并最终提高土壤的肥力。总而言之，化肥也可以被替代，生产出成本最低的有机生物肥料。因此可以解决使用化肥相关的问题，这是当今世界上最大的环境问题之一.
