The effect of Clamydomonas and Asterococcus green algae species on soil status conservation in sweet pepper growing

Absztrakt

In Hungary the most important vegetables is the sweet pepper (Capsicum annuum L.). In today’s agriculture the preservation of soil fertility is a very important factor. In plant cultivation we can use organic nutrients or fertilizers to supplement soil nutrients. In the summer period of 2012 in a sweet pepper (Capsicum annuum L.) growing experiment we used a complex Biofluid vermicompost and an organic nutrient composed of Clamydomonas and Asterococcus (Chlorophyta) green algae species. As control, we applied Poly-feed N:16; P2O5:9; K2O:26 chemical fertilizer containing micronutrients for sweet peppers. At the end of the growing period we analysed the soil samples for humus status and other nitrogen-containing compounds of soil. The natural soil conditions can only be restored by eco-friendly materials, which increase the productivity of the soil, but do not threat the environment. They restore the original ecosystem, which has been steadily destroyed by industrial production.
