“…All these factors may provide a potentially active form of biological control of plant pathogens through the establishment of soil suppressiveness -defined as the capacity of soils to restrict the survival and activity of plant pathogens - (Alabouvette et al, 1996). Yet, the efficiency of soil solarization can sometimes be greatly improved by combining it with the incorporation of various organic amendments such as composts, crop residues, green and animal manures (Gamliel and Stapleton, 1993a;Gamliel et al, 2000;Haidar and Sidahmed, 2000;Harender, 2004;Ozores-Hampton et al, 2005;Stevens et al, 2003). Beneficial effects of organic amendments are related to an altered composition of the soil microbiota that would favour biological control over a broad spectrum of soilborne plant pathogens (Hoitink and Boehm, 1999;Spadaro and Gullino, 2005), and to an increased release of toxic volatile compounds originating from the decomposing organic materials when heated (Gamliel and Stapleton, 1993b;Gamliel et al, 2000).…”

Soil solarization, alone or combined with organic amendment, is an increasingly attractive approach for managing soil-borne plant pathogens in agricultural soils. Even though it consists in a relatively mild heating treatment, the increased soil temperature may strongly affect soil microbial processes and nutrients dynamics. This study aimed to investigate the impact of solarization, either with or without addition of farmyard manure, in soil dynamics of various C, N and P pools. Changes in total C, N and P contents and in some functionally-related labile pools (soil microbial biomass C and N, K 2 SO 4 -extractable C and N, basal respiration, KCl-exchangeable ammonium and nitrate, and water-soluble P) were followed across a 72-day field soil solarization experiment carried out during a summer period on a clay loam soil in Southern Italy. Soil physico-chemical properties (temperature, moisture content and pH) were also monitored. The average soil temperature at 8-cm depth in solarized soils approached 55°C as compared to 35°C found in nonsolarized soil. Two-way ANOVA (solarizationÂorganic amendment) showed that both factors significantly affected most of the above variables, being the highest influence exerted by the organic amendment. With no manure addition, solarization did not significantly affect soil total C, N and P pools. Whereas soil pH, microbial biomass and, at a greater extent, K 2 SO 4 -extractable N and KCl-exchangeable ammonium were greatly affected. An increased release of water-soluble P was also found in solarized soils. Yet, solarization altered the quality of soluble organic residues released in soil as it lowered the C-to-N ratio of both soil microbial biomass and K 2 SO 4 -extractable organic substrates. Additionally, in solarized soils the metabolic quotient (qCO 2 ) significantly increased while the microbial biomass C-to-total organic C ratio (microbial quotient) decreased over the whole time course. We argued that soil solarization promoted the mineralization of readily decomposable pools of the native soil organic matter (e.g. the microbial biomass) thus rendering larger, at least over a short-term, the available fraction of some soil mineral nutrients, namely N and P forms. However, over a longer prospective solarization may lead to an over-exploitation of labile organic resources in agricultural soils. Manure addition greatly increased the levels of both total and labile C, N and P pools. Thus, addition of organic amendments could represent an important strategy to protect agricultural lands from excessive soil resources exploitation and to maintain soil fertility while enhancing pest control.

“…Solarization involves the use of transparent polyethylene sheeting to trap the heat from solar radiation to raise soil temperature to levels that are lethal to weed seeds and seedlings. In this regard, Haidar & Sidahmed (2000) have found that solarization for 2, 4 and 6 weeks with chicken manure has increased the average weight of cabbage plants by 55, 70 and 75%, respectively compared to the control with chicken manure. Candidoa et al (2011) have found that the average lettuce marketable yield was always found significantly higher in solarized soil than in untreated control in both greenhouse and in the field.…”

Weed Control in Clean Agriculture: A Review1

-Weed control is consider the major obstacle for the growers in the organic farming. Lower plant productivity in organic farming mainly related to the poor weed control. It is widely known, in most cases, that losses caused by weeds exceeded the losses from any category of agricultural pests. Under water-stress condition, weeds can reduce crop yields more than 50% through moisture competition alone. In the light of the environmental and toxicological problems created by herbicides, it has become necessary to develop the safety methods for controlling weeds. Soil Solarization, Mulching, Biodegradable Mulch, Natural Herbicides, Hot Water, and Agronomic Practices have been successfully adopted in many countries as safe methods for controlling weeds in the organic farming. In addition, there are some promising new and non-traditional measures such as Fresnel Lens, Electrical Weed Control, Lasers, etc which could be employed for controlling the weeds in organic farming. Also the agronomic practices such as choice of competitive varieties, stale seedbeds had a significant impact on weeds. The growers in organic farming should keep these three points in mind: 1) start clean stay clean successful, 2) Prevention is always better than treatment and, 3) One year's seeds will lead to seven year's weed infestation. Successful and sustainable weed management systems are those that employ combinations of techniques rather than relying on one method. The objectives of this paper are to review some safe weed control methods in the clean agricultural.Keywords: weeds, Safety methods, Mulch, Soil solarization, Natural herbicides, hot water, non-traditional methods.

“…Solarization along with green manuring suppressed annual bluegrass significantly (Peachey et al 2001). Integrated use of polyethylene sheets and poultry manure mulch affected emergence of field dodder (Cuscuta campestris Yuncker) (Haidar and Sidahmed 2000). Solarization for 2 mo with polyethylene covering killed 95% of broomrape (Orobanche ramosa L.) seeds (Mauromicale et al 2005).…”

Nonconventional Weed Management Strategies for Modern Agriculture

Weeds are a significant problem in crop production and their management in modern agriculture is crucial to avoid yield losses and ensure food security. Intensive agricultural practices, changing climate, and natural disasters affect weed dynamics and that requires a change in weed management protocols. The existing manual control options are no longer viable because of labor shortages; chemical control options are limited by ecodegradation, health hazards, and development of herbicide resistance in weeds. We are therefore reviewing some potential nonconventional weed management strategies for modern agriculture that are viable, feasible, and efficient. Improvement in tillage regimes has long been identified as an impressive weed-control measure. Harvest weed seed control and seed predation have been shown as potential tools for reducing weed emergence and seed bank reserves. Development in the field of allelopathy for weed management has led to new techniques for weed control. The remarkable role of biotechnological advancements in developing herbicide-resistant crops, bioherbicides, and harnessing the allelopathic potential of crops is also worth mentioning in a modern weed management program. Thermal weed management has also been observed as a useful technique, especially under conservation agriculture systems. Last, precision weed management has been elaborated with sufficient details. The role of remote sensing, modeling, and robotics as an integral part of precision weed management has been highlighted in a realistic manner. All these strategies are viable for today's agriculture; however, site-specific selection and the use of right combinations will be the key to success. No single strategy is perfect, and therefore an integrated approach may provide better results. Future research is needed to explore the potential of these strategies and to optimize them on technological and cultural bases. The adoption of such methods may improve the efficiency of cropping systems under sustainable and conservation practices.
