“…For organic waste, Corti et al (1998) and Erhart and Burian (1997) reported that the EC of composts ranged between 0.14 and 12.2 mS cm -1 . In the experiment 3, the EC of composting product did not exceed the limit content of 3 mS cm -1 , which indicated that EC would not adversely affect the plant growth (Soumaré et al 2002).…”

This study aimed to determine the initial air pressure influence on the in-vessel composting for the biodegradable fraction of municipal solid waste in Morocco. For this purpose, representative composting mixture was prepared in which C/N ratio was 26 and moisture content was 70 %. The in-vessel bioreactor was designed and used specially to evaluate the initial air pressure effect on composting process in this study. Thus, daily changes of internal air pressure and temperature were monitored, and physicochemical properties of different composts obtained were also analyzed and compared. Experimental results showed a significant increase in internal pressure corresponding to the initial air pressure of 0.6 bar and a slight increase for the other initial air pressures. The initial air pressure which equal to 0.6 bar allowed maximum value of temperature and final composting product with good physicochemical properties as well as higher organic matter degradation and higher gas production. Composts obtained from experiments under 0.4 and 0.8 bar showed good maturity levels and may also be used for agricultural applications.

“…Pendant la progression du compostage, la volatilisation de l'ammoniac et de la précipitation des sels minéraux peuvent être les raisons possibles de la diminution de la CE jusqu'à la phase finale de compostage (Wong et al, 1995). Le CE du produit de compostage final ne dépasse pas la teneur limite de 3 ms/cm, ce qui indique que CE ne serait pas nuire à la croissance des plantes (Soumaré et al 2002). …”

This work is in the context of the management and recycling of solid urban waste. The evolution of the physicochemical and microbiological parameters during composting pilot scale household waste was studied. The maturity of the processes and the agronomic value of the finished product were examined. The results showed that the organic fraction of solid waste could be composted successfully in 60 days and revealing a vigorous microbial activity. The final compost has been satisfactory for its agricultural application. Phytotoxicity tests conducted on wheat and tomato crops, show that the incorporation of 25% culture support the compost allows a germination rate of up to 85% against 70% for the control for the variety of corn. In the case of tomatoes, we recorded a germination rate of about 67% against 58% for the control.

L'évolution des paramètres physicochimiques et microbiologiques au cours du compostage à l'échelle pilote des déchets ménagers a été étudiée. La maturité du process et la valeur agronomique du produit fini ont été examinées. Les résultats obtenus ont montré que la fraction organique des déchets solides pourrait être composté avec succès dans un délais de 60 jours et révélant une activité microbienne vigoureuse. Le compost final a été satisfaisant pour son application agricole. Les essais de phytotoxicité menés sur des cultures de blé et de la tomate, révèlent que l'incorporation de 25% du compost au supports de culture permet un taux de germination allant jusqu'à 85 % contre 70 % pour le témoin pour la variété du blé. Dans le cas de la tomate, nous avons enregistré un taux de germination de l'ordre de 67 % contre 58 % pour le témoin.

“…Compost increased soil nutrition, that is to say nitrogen, phosphorous and potassium, but the variation in nitrogen concentrations was higher than in phosphorous and potassium. Another study reported that nutrient availability increased incrementally according to composting application (Soumaré et al 2002) and treated plants performed better when compared to the controls.…”

“…In terms of phosphorous and potassium, differences among compost types and plants were negligible. In this respect, Sundara et al (2002), Soumaré et al (2002), Cavender et al (2003), Jat and Ahlawat (2004) and many researchers hold the opinion that bio fertilizers, such as compost, improves soil characteristics and soil nutrition contents. The advantage of compost in terms of nutrition is that it facilitates the slow release of nutrients, which extends the long term benefits of compost treatment (Inckel et al 2005).…”

There are different types of compost used as soil conditioners and fertilizers. Plants can have different responses to different forms of compost. This field study was performed to examine the effects of different types of compost on growth factors of three dry rangeland species (Atriplex, Atriplex lentiformis; Saltwort, Seidlitzia rosmarinus; Haloxylon, Haloxylon persicum) and soil properties. The experiment was conducted in the Fars Province of Iran during the year 2010-2011. Compost applications consisted of compost tea, solid compost (SC), solid and liquid mixture (MX) and no compost as the control. The study was a factorial experiment based on a randomized complete block design with 3 replications. The results showed that all the tested compost applications enhanced the growth traits of all three species. It was also demonstrated that the use of compost significantly increased the organic matter (1% probability level [PL]), nitrogen concentration (5% PL), phosphorous (5% PL) and potassium (5% PL) concentrations of the soil. The soil's pH level was unchanged (range, 7.3 to 7.6), and the sodium concentration was also significantly decreased (1% PL) by the use of compost. The higher responses were observed in canopy volume and soil sodium and the lower were observed in stem diameter and soil pH level. Among the three plants in the study, Atriplex showed the best response to the application of compost. Based on the results of this study, it can be recommended that the best compost application to increase growth and improve soil condition is the mixed compost (MX) for Atriplex and the SC for Saltwort and Haloxylon.
