Abstract

The research was carried out at the laboratories of the General Commission for Scientific Agricultural Research GCSAR, during the period 2/11/2016 to 2/12/2016. It aimed to study some of the compost characteristics of organic matter fermentation at Wadi Al – Huda Center for solid waste treatment in Tartous. Two experiments were carried out to identify the changes in its characteristics, the first experiment after the use in agriculture or over time after storage for a year with three replicates for each treatment, and the second for the compost filter after washing eight times and three replicates per leachate. The results showed good content of the organic material in the three compost treatments (new, planted, stored), and the percentage of organic matter significantly decreased after cultivation, C/N ratio= 1/13 and good content of major essential nutrients. The percentage of heavy elements within the permissible limits, without significant differences between the three treatments, but it was found that the salinity decreases after the use in agriculture and increased after storage significantly, while the value of pH was reduced by insignificant differences after storage and use in agriculture. The increase in the washed compost led to an intestinal increase in the value of pH and a significant decrease in the value of salinity and relative stability in the content of nutrients and heavy elements.

Abstract

This study aimed to assess the impact of nitrogen fertilizer, and biogas manure on the productivity of hybrid maize crop (cv. Merritt), and some soil properties, at Western Zahid Research Station, Agricultural Research Center of Tartous, GCSAR/Syria, during the seasons 2011, 2012, and 2013. Complete Randomized Block Design (CRBD) was adopted with three replicates. The treatments were 12 (3 levels of nitrogen fertilizer i.e., 0, 12, and 24 kg/ha, and 4 levels of biogas manure i.e., 0, 6, 8, and 10 l/ m2). The results showed a significant increase in the productivity of maize by increasing the addition of manure biogas and mineral nitrogen fertilizer. The best treatment was fertilized by 24 kg N/ ha, and 10 l/m2 of biogas manure in all three seasons (15.82, 16.31.16.89 ton /ha, respectively). Soil organic matter was increased in most treatments which fertilized with biogas manure. It was observed a gradual increase in the soil organic matter with the increment in manure biogas in the absence of N fertilizers compared with the control. Total nitrogen increased in the soil gradually by increasing the addition of manure biogas. As well as the available phosphorus and potassium in soil increased in all treatments of manure biogas.

Key words: Manure biogas, N fertilizers, Organic matter, Soil properties, Maize.
