Organic Soil Amendments for Sustainable Agriculture: Organic Sources of Nitrogen, Phosphorus, and Potassium
Sustainable agriculture, which is characterized by farming profitably while minimizing damage to the environment, is not easy to practice. “Conventional” agriculture in the USA is commonly considered to involve practices that have potential to damage the environment. These include tilling the soil excessively, overapplying readily soluble inorganic fertilizers (“chemical fertilizers”), and over...
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 کاملChemical attributes of soil under no-till farming affected by crop systems and fertilization sources
Crop systems and fertilization sources can affect the chemical properties of the soil and, consequently, its fertility. With the aim of evaluating the effect of such management practices, soil samples collected at 0.0-0.10; 0.10-0.20; and 0.20-0.40 m in depth were collected and analyzed in the second year of an experiment installed in 2006 in a Rhodic Hapludox under no-till farming, located in ...
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 کاملSorption and fractionation of dissolved organic matter and associated phosphorus in agricultural soil.
Mobility of dissolved organic matter (DOM) strongly affects the export of nitrogen (N) and phosphorus (P) from soils to surface waters. To study the sorption and mobility of dissolved organic C and P (DOC, DOP) in soil, the pH-dependent sorption of DOM to samples from Ap, EB, and Bt horizons from a Danish agricultural Humic Hapludult was investigated and a kinetic model applicable in field-scal...
