Crop plants can funnel water to the soil and increase content more in row relative interrow. Because intercepts after rains higher root density, may also dry out between than does The objectives of this study were determine if there is a position difference wetting rain drying rains, seasonal nature these differences. first experiment examined 0 0.06 m row, interrow, quarter corn positions for eight sites at specific times during (Zea mays L.)-growing season. During growing season, second automated measurements one site two years soybean (Glycine max [L.] Merr.) year interrow 0.15-m depth. Soil changes significantly greater some mid-season dates. Temporal showed that dominated over mid mean ratio row/(row + interrow) was 0.76 0.77 0.64 0.58 0.84 0.60 soybean. Soybean effect shorter time season (up 71 days) compared with 159 days).
