Effects of Several Plant Cultivation System on Decreasing Residual Nitrate in Meadow Cinnamon Soil on North China Plain

Xiaotang Ju 2011

Other claims from this paper (8)

Observation Poplar nitrogen uptake fell in the following year and was below grass systems.
Observation Poplar root-zone and deep nitrate accumulation showed downward leaching.
Observation Catch crops had some deep-profile nitrate leaching.
Recommendation Grass monoculture or intercropping can rapidly reduce soil nitrate in high-nitrate soil.
Observation Tall fescue absorbed more topsoil nitrogen than other plants.
Observation Alfalfa had an advantage for relatively long-term restoration.

Organic waste amendments as sources of carbon and fertility for vegetable production

Rebecca J. Long Journal of Media Literacy Education 2015

Other claims from this paper (16)

Observation Amendment properties varied by waste and year without problematic EC or heavy metals.
Observation Amendment nutrient density was generally low, with substantial N and P in GW.
Mechanism Seashells in MS affected carbon estimates and soil pH.
Intervention effect Amendments did not significantly alter soil moisture, heavy metals or EC.
Intervention effect MS increased soil pH relative to control.
Intervention effect YW and BS increased soil organic matter relative to control, inconsistently across crops.
Intervention effect Waste amendments did not reliably raise late season inorganic or potentially mineralizable N.
Intervention effect PF did not consistently lower inorganic N relative to control.
Intervention effect PF lowered potato emergence in 2014.
Intervention effect PF shortened potato plants in 2013 and 2014.
Association Plant tissue nutrient levels varied with treatment without tracking application rates.
Observation Some crop tissues were deficient in K, Mn, B and Zn.
Intervention effect Corn cob heavy metals did not differ significantly among treatments.
Intervention effect GW, BS and FW yielded comparably to control across crops.
Intervention effect YW, PF and MS underperformed control for corn or squash but matched it for potatoes.
Intervention effect PF improved potato quality in 2014.
