Description Alfisols are abundarrt soils used for rainfed agrkulfure but have a wide rarrse of problrrtrs due lo lora irrfilfratiorr rates.
We studied a ranse of soil and crop managemenl options (fillngc and muklring for anrtunl crops, a~rrl ~wrerrninl crolrs) t:, incrcase
infiltration during 1989 and 1990. With annual crops sfraw ~rrul~.ahn d FYM trrulch reducrd runof by 52% ar~d1 7% reslwcfitrly compared
to barc freatmenfs but tillage h d small and inconsislent effecfs. Perennial crops produced high rutaolf duritrg the esfahlisl~~rrepnetr iod
in 1988 and sukquetrfly a wide range of response depending or1 flu foliage slructure of fire r.roj>. Tall groroirtg pererrnial

reduced runofl more than straw mulch. Reduction in runof will decrease soil erosion and nrny increme draitra~e by up to 200 nrm
