The utilization of organic wastes to improve soils or for growth media components in local farms and nurseries can reduce the environmental pollution linked to waste disposal while increasing the sustainability of crop production. This approach could be applied to waste products generated from the production of guacamole (an emerging activity in the avocado production areas in mainland Spain), ...

In this study, odorous volatile compounds (OVCs) from market−ready, commercial composts supplied by 14 different producers were compared using a recently developed method involving solid−phase microextraction (SPME) of headspace volatiles followed by GC analysis. The products analyzed were derived from a cross−section of the wide array of compost feedstock ingredients used in the U.S. (e.g., bi...

Phytophthora root rot caused by Phytophthora nicotianae is an economically important disease in pepper crops. The use of suppressive composts is a low environmental impact method for its control. Although attempts have been made to reveal the relationship between microbiota and compost suppressiveness, little is known about the microorganisms associated with disease suppression. Here, an Ion To...

While the results of a twoseason study at only one location are too limited to conclude that incorporation is never necessary (it is likely that there are soil or weather conditions for which incorporation provides superior growth) they indicate that there are a variety of composts and weather conditions for ● Blanket applications of all three composts produced as much planted vegetation as tes...

The viability of composting as a practical alternative for disposal of the large quantities of organic wastes generated by municipalities, industry and agricultural procesSing depends, to a large degree, on adequate local markets for fished compost. In m y areas, the use of composts as soil ameadments in nearby agridtural fields offqs a large potential mark&. The benefits of adding stabilized o...

The utilization of compost vineyard wastes as suppressive growing media against Fusarium wilt is a good alternative for the disposal and recycling of these organic wastes. Inoculation of biological control agents (BCAs) enhances the biocontrol activity of compost. In this experiment, vineyard compost was sampled at different stages during the composting process, rating the values of acceptabili...

Several species of Legionella cause Legionnaires' disease (LD). Infection may occur through inhalation of Legionella or amoebal vesicles. The reservoirs of Legionella are water, soil, potting soil and compost. Some species of free-living amoebae (FLA) that are naturally present in water and soil were described as hosts for Legionella. This study aimed to understand whether or not the composting...

Compost use in landscaping and erosion control applications has become widespread. Various types of composts have been utilized on highway embankments for soil conservation and runoff reduction. Different compost materials could have different erosion control effects. The objective of this study is to investigate the erosion resistance of three commonly used composts and their effects on slope ...

Herbicide residues have raised new concern since 1999 when damage to plants appeared to result from composted turf clippings (Bary et al. 2001; Rynk 2000). Other case reports of some incidents suggested that other unknown sources of phytotoxicity were present in composts used in gardens (Nielson 2003). Several plant bioassays have been reported to test composts for herbicide residues (SPU 2002;...
