Does Soil Disturbance Affect Soil Phosphorus Fractions?
Increased turnover of organic matter as a result of soil disturbance (e.g. by soil tillage) is described in principle, but the direct influence of soil disturbance on soil P turnover especially for organic farming systems has not been sufficiently proven. The objective of the study was to evaluate the short term effect of soil disturbance on different soil P fractions in a soil shaking experime...
متن کاملAlberta Soil Phosphorus Limits Project
Agricultural systems often require added phosphorus to achieve optimum crop and livestock production. The application of soil amendments, such as inorganic fertilizers, manure, biosolids, and waste water, can improve soil fertility and help produce optimum crop yields. However, many of these amendments, particularly organic materials such as animal manure, are often applied in excess of crop nu...
متن کاملExtraction of soil organic phosphorus.
Organic phosphorus is an important component of soil biogeochemical cycles, but must be extracted from soil prior to analysis. Here we critically review the extraction of soil organic phosphorus, including procedures for quantification, speciation, and assessment of biological availability. Quantitative extraction conventionally requires strong acids and bases, which inevitably alter chemical s...
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...
متن کاملAssessing log extraction related soil disturbance and solutions to protect soil and reduce disturbance of forest ecosystem.
Skid trails are the main routes for wood extraction and also the main source of runoff and sediment production in Forests. This research was conducted in Kuhmiyan forest of Golestan Province to determine infiltration, compaction, strength (resistance to penetration) and moisture content in three treatment including control (in the forest), wheel ruts and middle of skid trail were measured in th...
