Soil application of inorganic source of iron (Fe) is not effective in correction of Fe deficiency in calcareous soils. The chelate form of Fe is, therefore, used for that purpose. Application of Fe‐chelate, however, may reduce crop yields due to th

Soil testing determines nutrient, lime, gypsum or S, leaching requirements for crops, and potential elemental toxicity to crops and/or their consumers. The majority of farmers do not use soil testing or use higher or lower than economic optimum nutri

Iron (Fe) deficiency is common in calcareous soils. Application of FeEDDHA is effective in correction of Fe deficiency in such soils. However, it may decrease concentration and uptake of some micronutrients including manganese (Mn). The effect of Fe

Information on Cl vs. SO 4 salinity effects on alfalfa (Medicago sativa L) dry matter yield (DM) and cation-anion balance is limited. Consequently, we compared Cl and SO 4 salinity effects on shoot DM and ionic balance for Archer and Ladak varieties

Portable chlorophyll meters have been reported to provide a new tool to rapidly assess the nitrogen (N) status of growing crops, but need further validation. This study was conducted on growers’ fields to determine if the portable chlorophyll meter

The diagnosis and recommendation integrated system (DRIS) is a potential method for interpreting plant foliar nutrient composition. The objective of our study was to compare DRIS with the nutrient sufficiency range (NSR) for corn (Zea mays L.). We us
