Elemental quantitation of natural organic matter by CPMAS 13C NMR spectroscopy.
Cross-polarized magic-angle-spinning NMR (CPMAS-NMR) techniques are assumed to be only semi-quantitative in the assessment of carbon distribution in humic substances or natural organic matter, due to a number of interferences such as spinning side bands (SSB) in spectra, paramagnetic species in samples, and low or remote protonation of aromatic carbons. Fast rotor spin rates or direct polarizat...
متن کاملOrganic Fertilizers and Composts
Introduction Interest in organic production methods for vegetables continues to increase. Production practices for organic field production of vegetables have a long history, but practices to grow organic vegetable transplants in a spring greenhouse are poorly known. Organic fertilizers and composts are available but the efficacy and rates for use have not been evaluated. Experiments in the sum...
متن کاملThree Southern Appalachian Balds through Soil Organic Matter Analysis
The history of Southern Appalachian grassy balds has long been a topic of speculation. Two types have been identified: those completely covered by grass and those occupied by a mixed-hardwood overstory with a grassy herbaceous layer. Three areas historically known as balds were identified in the Wine Spring Ecosystem Project Area. Each is currently under a different management regime. The objec...
متن کاملSustainable Agriculture, Soil Health, and Soil Organic Matter
The latter two principles protect the soil resource on which all food and fibre production ultimately depends. However, agricultural production systems differ from ‘natural’ or undeveloped systems in that they can be considered to be ‘leaky’ with respect to nutrients. This is inevitable, due to nutrient removal in harvested product, but inappropriate fertiliser management can exacerbate the ‘le...
