Abstract

After the decomposition of organic matter like plants a liquid is generated and can be used as fertilizer in the soil to enhance the growth of plants. The objective of this study was to compare the development of plants subjected to slurry, a commercial chemical fertilizer, and a control group to investigate the following questions: Was the height of the plants the same among the different groups? Was the growth equal among the other groups? Was survival the same between the various groups? Five groups were compared; control as organic soil without added nutrients, a commercial liquid chemical fertilizer, and finally, the liquid resulting from plant degradation in a compost bin (10ml, 20ml, 30ml). Each group had 20 replicates with one radish seed (Raphanus sativus). The groups were watered every three days, and the plants were measured for height every week for 11 weeks. As a result, the group with the lowest amount of slurry (10ml) achieved greater growth, but lower survival. The greater volume of leachate in the soil may present excess nutrients and have a toxic effect on plant growth and, studies analyzing soil with different proportions of leachate may test this hypothesis. Furthermore, future studies with native species will be able to evaluate the effect of organic slurry and the possibility of using it in seedling production protocols.
