1. Demonstration of Veris Nir Soil Carbon Mapping Technology The new VERIS Technologies Near Infra Red (NIR) Spectrophotometer compares soil spectral measurements with soil carbon (C) and other properties. These data can be utilized to generate maps of soil characteristics across the landscape. This potentially useful system may simplify the measurement of important soil properties, provide a new tool for evaluation of residue conservation management practices, and guide farmers in soil management decisions based on data heretofore unavailable. While growers... P. Carter, S. Van vleet, E. Perry, S. Young, F. Pierce
2. Biochar Volatile Matter Content Effects on Plant Growth and Nitrogen Transformations in a Tropical Soil Biochars made from modern pyrolysis methods have attracted widespread attention as potential soil amendments with agronomic value. A series of greenhouse experiments and laboratory incubations were conducted to assess the effects of biochar volatile matter (VM) content on plant growth, nitrogen (N) transformations, and microbial activities in an acid tropical soil. High VM biochar inhibited plant growth and reduced N uptake with and without the addition of fertilizers. Low VM charcoal supplemented... J. Deenik, A. Mcclellan, G. Uehara Download paper
