Extensive corn production in the midwestern United States has physically eliminated or fragmented vast areas of historical amphibian habitat. Midwestern corn farmers also apply large quantities of fertilizers and herbicides, which can cause direct and indirect effects on amphibians. Limited field research regarding the statuses of midwestern amphibian populations near areas of corn production h...

Limitations of rainfall and surface water resources farmers have to use both surface and subsurface resources for growing different crops. In this study optimal management of irrigation water allocation and cropping pattern utilizing conjunctive use of surface and subsurface water resources is studied. Also the effect of reducing water consumption in different growth stages with different irrig...

Farmers in many regions of the world grow a horticultural or grain crop between sugarcane (a complex hybrid of Saccharum spp.) cycles. This additional crop often requires higher amounts of P or K fertilizers than does sugarcane. Some sugarcane growers in Florida precede 2to 5-year cycles of sugarcane with one crop of spring-harvested sweet corn (Zea mays L.). A disadvantage perceived with this ...

Nitrogen is usually the most limiting nutrient for crop production. Thus, N fertilizer is widely used by farmers. Moreover, Mn deficiency in some calcareous soils of Iran with high pH has been reported. Therefore, the addition of nitrogen and manganese to achieve the optimum yield is necessary. The objective of this study was to evaluate the effect of N and Mn applications on the availability o...
