Ruzigrass 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...

متن کاملBurning in a New Zealand Snow-tussock Grassland: Effects on Soil Microbial Biomass and Nitrogen and Phosphorus Availability
Although fire is a controversial management tool in New Zealand tussock grasslands, it can be an important factor in their pastoral use (Basher, Meurk and Tate, 1990). Its effects on various properties of these ecosystems have, consequently, been widely studied. Most biochemical studies of the effects of burning on grassland soils have concentrated on the availability of nutrient elements, espe...
متن کاملAltitudinal Gradient of Microbial Biomass Phosphorus and Its Relationship with Microbial Biomass Carbon, Nitrogen, and Rhizosphere Soil Phosphorus on the Eastern Slope of Gongga Mountain, SW China
Microbial biomass phosphorus (MBP) is one of the most active forms of phosphorus (P) in soils. MBP plays an important role in the biogeochemical P cycle. To explore MBP distribution and its relationship with other factors, the MBP and rhizosphere soil P concentrations and fractions in six vegetation zones on the eastern slope of Gongga Mountain in SW China were investigated. The MBP distributio...
متن کاملMicrobial Activity and Phosphorus Availability in A Subtropical Soil under Different Land Uses
Land use changes in the Everglades Agricultural Area (EAA) of south Florida may alter microbial activity and organic matter decomposition and ultimately influence the fate of P in soil. The objectives of this study were to determine effects of long-term cultivation and fertilization on microbial activity and P dynamics for contrasting land uses in the EAA. Soils (0-15 cm) under pasture for 100 ...
