1. Calcium Chloride Effects on Nitrogen Uptake by Small GrainsApplying calcium chloride (CaC12) with urea stimulated nitrogen uptake by small grains in six greenhouse studies. The effect was most dramatic for a sandy soil, moderate for a loam soil, and not observed for a clay soil. Allowing the urea to nitrify before plant uptake negated the CaC12 effect. In field studies, these effects were generally not observed, probably because the nitrification of the applied N was too rapid. However, this concept deserves further investigation, for example, when established... |
2. County-Level Phosphorus Balances for 2017 in IllinoisCropland phosphorus (P) balances (manure and fertilizer P minus crop P removal) are great sustainability tools to assess long-term managements at farm, county, and state levels. Our objectives were to estimate county, regional, and state-level cropland P balances for Illinois in 2017. Based on the census data in 2017, Illinois county P balance ranged from -14.38 to 36 lb/acre/yr. Overall, Illinois had a negative P balance at about -3 lb/acre/yr. About 71% of counties, had a negative P balance,... X. Liu, S. Xu, A. Margenot, A. Sadeghpour, O. Zandvakili, M. Guzel |
