Bacterial Communities in the Rhizosphere of Amilaceous Maize (Zea mays L.) as Assessed by Pyrosequencing

Frontiers in Plant Science, 2016
Maize (Zea mays L.) is the staple diet of the native peasants in the Quechua region of the Peruvian Andes who continue growing it in small plots called chacras following ancestral traditions.

Characterizing the fine‐scale spatial distribution of soil phosphorus for efficient phosphorus management in an Illinois tile‐drained field

Journal of Environmental Quality, EarlyView.
Abstract Closed depressions in post‐glacial landscapes can accumulate phosphorus (P) due to repeated flooding and become hotspots for P loss when underlain by subsurface (tile) drainage. Soil P mapping is routinely based on the interpolation of samples from a 1‐ha grid, which may miss closed depressions and underestimate soil P levels leading to ...

Fall‐applied manure can conserve excess soil‐profile inorganic‐N for the subsequent cropping year

Journal of Environmental Quality, EarlyView.
Abstract To investigate dairy manure urea fertilizer interactions in cropped soils of the semiarid‐West, we fall‐applied and incorporated (0–0.3 m) soil urea‐N (FertN) rates of 10 (N0), 45 (N1), and 80 mg N kg−1 (N2), co‐applied with either no manure or 86 Mg ha−1 (dry wt.) stockpiled dairy manure.

COMPETITIVE ABILITY OF MAIZE IN MIXTURE WITH CLIMBING BEAN IN ORGANIC FARMING [PDF]

, 2005
Intercropped crops represent an important production system in organic farming, especially maize/climbing bean mixture due to its high content of protein in bean seeds for human diet, and producing silage for ruminants.

Testing Wisconsin P index assessments across cropping systems

Journal of Environmental Quality, EarlyView.
Abstract Managing agricultural runoff phosphorus (P) often requires understanding management effects on both dissolved P (DP) and particulate (sediment‐bound) P (PP). The Wisconsin P index (WPI) allows producers to assess land management effects on runoff P by estimating annual P losses in mass per unit area.

Delaying application and injecting nitrogen fertilizer with urease and nitrification inhibitors decreased nitrous oxide emissions and enhanced corn yields

Journal of Environmental Quality, EarlyView.
Abstract Early season nitrous oxide (N2O) emissions following nitrogen fertilizer application can be significant if spring rains lead to anaerobic conditions before the crop is established and able to utilize the applied N. However, delaying fertilizer application by 4‐5 weeks after planting usually results in warmer temperatures which promote ammonia (

Late spring urea application increased apparent carbon dioxide equivalence emissions but fall and summer applications did not

Journal of Environmental Quality, EarlyView.
Abstract Synchronizing nitrogen (N) fertilizer application with plant N uptake, as opposed to applying earlier, is believed to improve N use efficiency while simultaneously reducing nitrate leaching, ammonia volatilization, and greenhouse gas emissions. However, little research has been conducted to confirm that this is true.
