Influence of water solubility of granular zinc fertilizers on plant uptake and growth

摘要: Abstract Zinc (Zn) fertilizer application has increased during the past three decades. This increase created need for more information regarding availability and agronomic effectiveness of Zn containing fertilizers because differences opinions exist relating relationships between water solubility plant availability. Plant eight commercialized materials having different solubilities was measured under greenhouse conditions. Corn (Zea mays L.) plants were grown 40 days in a soil (loamy, mixed, mesic arenic Ustollic Haplargid) amended with lime to two pH's: 6.3 7.4. To evaluate effect pH, some used at both pH levels while all 7.4 soil. The experimental design factorial combination fertilizers, rates 0,2.1,4.2,8.4 mg kg−1 Dry matter production uptake significantly when decreased from 6.3. highest dry ...
