Application of Organic Fertilizers Based on Sapropel and Peat in Countries of Middle East

Abstract

Recently, several studies on the application of organic-mineral fertilizers (OMF), based on sapropel and peat), were carried out in Middle East countries. The OMF named “Sapro Agro” (manufactured by LLC LATPOWER, Riga, Latvia) was tested in Saudi Arabia in organic agriculture, as a fertilizer as well as a soil conditioner, while the study of the OMF named “Humin Plus” was conducted in Jordan. Results of the effects of Humin Plus on the pre-treatment of soil in greenhouses showed that yield increased 24%. The study of the effects of Humin Plus on cucumbers in greenhouses showed yield increased by 31%. An experiment on plants which are lagging behind in their development caught up and surpassed other plants in appearance when treated with Humin Plus. Also, researches in Jordan showed that Humin Plus was very effective in the early stages of fruiting and the optimal application rate of this OMF in this case was 1 ltr/10000 m2. In Jordan, several experiments were conducted with Sapro Agro and Sapro Elixir, which were mixed with mineral fertilizer (Kama-Eco+) at a ratio of 50/50. Results of these experiments showed that yield increased 28-35%.
