  abstract = {{I}n {S}udano-{S}ahelian agriculture, organic amendments are often limited by resource availability. {S}mall branches (ramial wood, {RW}) represent an organic resource found in many landscapes but little is known about their effects. {T}his field trial (2007–2009) studied the effects of {RW} or straw at low application rate (0.69 {M}g {C} ha−1 year−1) on topsoil carbon ({C}), nitrogen ({N}) and available phosphorus ({P}, {P}av), termite cast abundance, and sorghum yield. {S}traw and {RW} were chopped and either buried ({S}t{B}u, {W}o{B}u) or mulched ({S}t{M}u, {W}o{M}u). {M}ineral fertilizers were added to straw so that {RW}- and straw-amended plots received similar applications of {C}, {N}, {P}, and potassium. {A}nother treatment had {RW} buried with additional {N} ({W}o{B}u{N}), and there was a control ({C}trl). {B}ranches came from {P}iliostigma reticulatum, very common in the area. {T}he treatments had little significant effect on topsoil and crop, owing to the low application rate and spatial variability. {H}owever, {P}av was significantly lower with buried than mulched amendments in 2009, and decreased significantly over time in {C}trl and with buried amendments. {T}opsoil {C} also decreased significantly with time in {W}o{M}u. {S}ignificantly more termite casts were observed with {RW}. {T}he sorghum yield averaged 0.87 {M}g {DM} ha−1 in 2007 and then decreased. {T}he treatments affected yield significantly in 2008 only: it was higher in {W}o{B}u{N} and {S}t{B}u than in {C}trl. {I}n 2009, the yield was mainly affected by initial topsoil {P}av. {T}hese results suggest that {RW} stimulated biological activity, leading to {P} immobilization and {C} mineralization, but had little effect on yields.},
