Phosphorus Availability to Barley from Manures and Fertilizers on a Calcareous Soil
High concentrations of animal production in the United States have increased the concern about the environmental fate of phosphorus (P) in manures. We conducted a growth chamber study to develop phosphorus source coefficients (PSCs) for manures and fertilizers typically land applied and incorporated into calcareous soils of the western United States as well as to determine the potential plant P...
متن کاملPhosphorus runoff from two water sources on a calcareous soil.
Phosphorus (P) in irrigation runoff may enrich offsite water bodies and streams and be influenced by irrigation water quality and antecedent soil surface conditions. Runoff, soil loss, and P fractions in runoff using reverse osmosis (RO) water or mixed RO and well water (RO/ Tap) were studied in a laboratory sprinkler study to evaluate water source effects on P transport. A top- or subsoil Port...
متن کاملOrganic Phosphorus Source Effects on Calcareous Soil Phosphorus and Organic Carbon
The loading, solubility, mobility, and plant availability of P is a growing environmental concern to regulators and planners of nutrient management plans, confined animal feeding operations, and wastewater land application permit sites. Insufficient information is available on how P reacts from different organic sources when applied to calcareous soils. A field study was conducted to determine ...

متن کاملRuzigrass affecting soil‐phosphorus availability
The objective of this work was to evaluate the effectiveness of ruzigrass (Urochloa ruziziensis) in enhancing soil‐P availability in areas fertilized with soluble or reactive rock phosphates. The area had been cropped for five years under no‐till, in a system involving soybean, triticale/black‐oat, and pearl millet. Previously to the five‐year cultivation period, corrective phosphorus fertiliza...
