Comparing various sulfur sources for soybean grown on an acid Oxisol in Brazil

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3420-3428, November/December 2022., 2022
Abstract A greenhouse experiment and a 2‐yr field trial were conducted to compare various S sources for soybean [Glycine max (L.) Merr.] grown on an acid Oxisol in Brazil. In the greenhouse, the sources included ammonium sulfate (AMS), monoammonium phosphate with a S ratio = 50:50 of AMS/elemental S (ES) – (AMS + ES), and ES + bentonite containing 90 ...

Cropping system diversity and tillage intensity affects wheat productivity in Texas

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3498-3514, November/December 2022., 2022
Abstract Wheat (Triticum aestivum L.) production in Texas depends heavily on conventional tillage (CT) and a long summer fallow period, which contributes to soil degradation. This study compared the impact of reducing tillage intensity (CT, no‐tillage, and strip‐tillage) combined with summer cropping to CT–summer fallow on wheat establishment, grain ...
