Description Crop residue use for soil mulch and animal feed are the two major competing purposes and the basic
source of fundamental challenge in conservation agriculture (CA) where residue retention on farm plots is
one of the three CA principles. Using survey data from Kenya and applying bivariate ordered Probit and
bivariate Tobit models, this paper analyzes the tradeoffs in maize residue use as soil mulch and livestock
feed in mixed farming systems. Results show that both the proportion and quantity of maize residue used
for soil mulch and livestock feed are strongly affected by agroecology and livestock holding. Farmer
knowledge about alternative use of crop residues and farmer perception of soil erosion risk (proxied
through plot steepness) positively affect the amount of residue farmers retain on maize plots. Results
imply that crop residue use as soil mulch in conservation agriculture is challenged in mixed croplivestock
systems and particularly by smallholder farmers owning cross-bred and exotic dairy animals. In
general, reducing the demand for crop residues as livestock feed through the introduction of alternative
feed sources, better extension services on the use of crop residue as soil mulch and designing agroecology
specific strategies and interventions could facilitate the adoption and expansion of CA-based practices in
mixed crop-livestock systems.
