Use of two green algae Ulva lactuca and Ulva intestinalis as bio-fertilizers

Abstract

In recent years,  development have been witnessed in the market expansion of agricultural inputs and products including substances and materials that improve the functioning of soil, plants and the interactions between soil and plant. This is a very broad category of products and substances that often bring innovative solutions in the field of fertilization and crop protection.

The objective of this study is to improve the production of market garden where tomato plants in nurseries from powders of two green algae Ulva lactuca and Ulva intestinalis, harvested as bio-fertilizers in the west coast of Mostaganem province. They have minimal effects on the environment, including soil, subterranean water, River and Estuary ecosystems such as Cheliff River, biodiversity and global warming.

The experimental part was carried out following the method of extraction of algae and used as a bio-fertilizer on tomato to its simplicity and accuracy, which is the subject of the study of the germination, growth and the development of young plants.

The results of this study showed that algal powder of Ulva lactuca and Ulva intestinalis exhibit a remarkable stimulatory effect on the cultivation of tomato, which aims to improve their production, and evident when compared to controls setup.
