The use of double-cropping in combination with no-tillage and optimized nitrogen fertilization reduces soil NO emissions under irrigation.

The irrigation systems of the Ebro valley can lead to high NO emissions. The effects that crop diversification, such as double-cropping in combination with conservation tillage and different N fertilizer ratios, has on soil NO emissions have not been extensively studied in this region. The goal of this research was to measure NO soil emissions and determine the tillage practices and N fertilization rates that provide the lowest emissions when combined with double-cropping systems.

Influence of Agronomic Factors on Mycotoxin Contamination in Maize and Changes during a 10-Day Harvest-Till-Drying Simulation Period: A Different Perspective.

Agronomic factors can affect mycotoxin contamination of maize, one of the most produced cereals. Maize is usually harvested at 18% moisture, but it is not microbiologically stable until it reaches 14% moisture at the drying plants. We studied how three agronomic factors (crop diversification, tillage system and nitrogen fertilization rate) can affect fungal and mycotoxin contamination (deoxynivalenol and fumonisins B and B) in maize at harvest.
