Impact of nitrogen uptake on field water balance in fertirrigated melon [PDF]

open access: yesAgricultural Water Management, 2013
Agronomic management in Ciudad Real, a province in central Spain, is characteristic of semi-arid cropped areas whose water supplies have high nitrate (NO3?) content due to environmental degradation. This situation is aggravated by the existence of a restrictive subsurface layer of ?caliche? or hardpan at a depth of 0.60 m.

World Phosphorus Use Efficiency in Cereal Crops

open access: yesAgronomy Journal, Volume 109, Issue 4, Page 1670-1677, July–August 2017., 2017
Core Ideas A current estimate of global P use efficiency for cereal production is not available. This study shows that world P use efficiency for cereal crops is low. Using the difference method, average world P use efficiency from 1961 to 2013 was 16%. A current estimate of global phosphorus use efficiency (PUE) for cereal production is not available.
