Organic horticultural soils lose anywhere from 0.3 to 4 cm of viable topsoil each year that does not regenerate. The main degradation processes involve microbial decomposition, compaction (50%), and erosion (50%). Not much is known, however, about the actual magnitude of the loss due to erosion. The measurement of the spatial redistribution of cesium-137 (Cs-137) provides a rapid and efficient means to quantify this loss. We will measure this radioisotope in 28 fields exposed to different atmospheric agents and subject to a variety of anti-erosion practices in order to quantify the long-term (60+ years) severity of erosion for these soil types.

The project consisted of manufacturing and testing a portable rain simulator to estimate, under various conditions, what proportion of irrigation water a crop is able to use.

A labile carbon input would displace some phosphorus into the soil solution, thus making it available again for assimilation into growing plants.

Test whether or not commercial strains coated on Nantes carrot seeds can compete with native strains in the soil to colonize the host plant and, once symbiosis takes place, whether they succeed in doing a better job than the native strains during the transition to organic farming.
