The Effects of Rootstock Selection and Carbon-based Fertility Amendments on Apple Orchard Productivity and Soil Community Ecology
… Applications of composts, integrated compost-calcium nitrate fertilizers, and biochar increased soil carbon, organic matter, cation exchange capacity and microbial respiration. In the orchard study, nitrogen fertilizer application did not increase tree growth, fruit quality, or leaf nitrogen …

Optimizing nitrogen fertilization practices under intensive vineyard cover cropping floor management systems
… treatment (60 kg N/ha total split between two calcium nitrate applications at bloom and six weeks post bloom) and foliar fertilization (40 kg N/ha split over seven to nine urea applications); however, the foliar fertilization was most effective at increasing the concentration of certain …

Available fluoride ion in solution and one minute fluoride release rate of a toothpaste formulation
… For remineralization to occur, bioavailable calcium, phosphate, and fluoride ions must be present at the surface of the tooth. Toothpaste products supply bioavailable fluoride ions to the oral cavity. Calcium and phosphate ions are supplied primarily through the saliva, but in limited …
