“…Hypotheses that appear attractive are (i) recycling of elements through roots, (ii) chelate formation during corn root growth or decomposition (Stevenson and Ardakani, 1978), (iii) unknown or unrecognized deleterious effects from growing sugarbeets (Boawn, 1965) or from fallow, (iv) stimulatory substances given off from growing or decomposing roots, and (v) mycorrhizal effects (Vesicular-arbuscular mycorrhiza) (Lambert et al, 1979). Each of these hypotheses is not necessarily considered to be the sole factor responsible for enhanced Zn uptake following corn.…”

“…There were no apparent differences related to previous crop. The effect of sugarbeets on Zn nutrition of a subsequent corn crop has been interpreted as a deleterious effect (Boawn, 1965). Zinc uptake was low at both Zn fertilizer rates following sugarbeets and fallow compared to following corn.…”

“…His first test crop, sweet corn, showed a strong effect of previous crop on Zn nutrition (Boawn, 1965), whereas beans grown the 2nd yr did not (Boawn, 1985, personal communication). He concluded that the effect lasted only 1 yr.…”

“…De Remer and Smith (1964) also mentioned the detrimental effect of sugarbeets on a subsequent crop of beans and indicated that returning beet tops to the soil aggravated the Zn deficiency problem. Boawn (1965) concluded that the presence of beet tops did not influence the results of his experiment.…”

“…Zinc nutritional problems do not always arise following sugarbeets but they occur often enough to alert growers to the possibility. Boawn (1965) conducted a field experiment where sweet corn (Zea mays L.) was Zn deficient following sugarbeets but not following sugarbeets fertilized with Zn or sorghum (Sorghum bicolor L.). He concluded that sugarbeets had a deleterious effect on the Zn nutrition of subsequent crops.…”

Field observations indicated that Zn deficiency of beans (Phaseolus vulgaris L.) was sometimes more severe than expected when grown on fallowed soil that was low to marginal in available Zn. The objectives of this study were to determine the effects of fallow, sugarbeets (Beta vulgaris L.), and corn (Zea mays L.) on Zn availability to subsequent crops grown on a Portneuf silt loam (Durixerollic Calciorthids, coarse silty, mixed, mesic). The sugarbeet and corn plant tops and sugarbeet roots were removed, and 11.2 kg Zn ha−1 was applied on one‐half of each plot before fall plowing 25‐cm deep. Beans, sweet corn, or potatoes (Solanum tuberosum L.) were planted the following spring. Whole plant samples of beans and sweet corn and potato stems, leaflets, and petioles were sampled for chemical analyses during the growing season. All bean plants were Zn deficient when grown after fallow or sugarbeets but not after corn or where Zn fertilized. Potatoes and sweet corn did not show any Zn deficiency symptoms or any growth responses to Zn fertilization. The average zinc concentration in beans (vegetative development stage, V3) following corn was 20.5 mg kg−1 compared with 12.5 mg kg−1 following fallow or sugarbeets without Zn fertilization. The average Zn uptake by beans (V3) following corn was 1.3 g ha−1 compared with 0.6 g ha−1 after fallow or sugarbeets without Zn fertilization. The Zn uptake after corn was even greater than where 11.2 kg Zn ha−1 was applied to fallow or sugarbeets (1.3 vs. 0.9 g Zn ha−1). Enhanced Zn availability following corn persisted throughout the growing season and into a second bean crop, although at a decreased level. Similar trends occurred with potatoes and sweet corn. Soil DTPA‐extractable Zn was not significantly different after fallow, sugarbeets, or corn. These results indicate that Zn deficiency in sensitive crops may be alleviated or prevented depending upon the preceding crop grown, and that factors not measured by DTPA can significantly influence Zn availability.
