nservation Agriculture Research Updates - November 2017

This paper uses a meta-regression in combination with global soil and climate datasets to test 4 hypotheses: (1) that relative yield performance of conservation agriculture improves with increasing drought and temperature stress; (2) that the effects of moisture and temperature stress exposure interact; (3) that the effects of moisture and temperature stress are modified by soil texture; and (4) that crop diversification, fertilizer application rate, or the time since no-till implementation will enhance conservation agriculture performance under climate stress. Their results show that relative maize yield performance of CA improves with increasing drought severity and higher temperature. Further, there is an interaction of moisture and heat stress on conservation agriculture performance and their combined effect is both non-additive and modified by soil clay content, supporting our second and third hypotheses. There was limited support for the 4th hypothesis.
