Other claims from this paper (15)
- Intervention effect Soil organic carbon increased after urban plant debris addition in both years at the organic site.
- Intervention effect Soil organic carbon increased after urban plant debris addition only in the second year at the conventional site.
- Intervention effect Cation exchange capacity increased after urban plant debris addition in both years at both sites.
- Association A significant interaction between urban plant debris addition and production practices affected cation exchange capacity at the organic site in the second year.
- Intervention effect Soil phosphorus was not impacted by production practices or urban plant debris at either site.
- Intervention effect Urban plant debris addition decreased soil nitrate in 1999 at the organic and conventional sites, except under no-till treatments.
- Intervention effect Soil nitrate levels were not affected by urban plant debris or production practice in 2000.
- Intervention effect Stand counts of pepper were severely reduced in no-till treatments by intense competition from weeds.
- Intervention effect Soil fumigation gave marketable pepper yields equal to or above the statewide conventional average at the conventional site in 1999.
- Intervention effect Soil solarization gave marketable pepper yields equal to or above the statewide conventional average at the conventional site in 1999.
- Intervention effect Under soil solarization, marketable yield at the organic site approached the statewide conventional average.
- Intervention effect Yields under plastic mulch increased at both sites with urban plant debris addition.
- Intervention effect Organic pepper yields from soil-solarized plots were similar to yields of conventional farmers using high nitrogen inputs.
- Recommendation No-till systems for fall production do not appear to be a viable alternative under Florida conditions because weeds proliferate under the cover crop stubble.
- Association A Phytophthora capsici blight epidemic eliminated pepper production at the conventional site in 2000.
