Landfill leachates are pollutants rich in ammoniacal N, Na, and K, but land application potentially offers an alternative for recycling these leachate nutrients. We applied landfi ll leachate corresponding to 0, 110, 220, 330, and 440 kg ha-1 of total N, divided in three applications ( July, August, and October 2008), onto the surface of an acidic (pH 5.5-6.0) clay (79% clay) Ultisol and monitored NH3 volatilization just after applications and microbiological (0-10 cm) and chemical attributes (0-60-cm soil depth) in August 2008, January 2009, and May 2009. Ammonium (up to 30 mg kg-1), NO3 - (up to 160 mg kg-1), Na, K (up to 1.1 cmolc kg-1 each), and electrical conductivity (up to 1 dS m-1) increased transiently in soil following applications. Despite >90% of the total leachate N being ammoniacal, NO3 - predominated in the first soil sampling, 14 d aft er the second application, suggesting fast nitrifi cation, but it decreased in the soil profi le thereafter. From 5 to 25% of the total applied N volatilized as NH3, with maximum losses within the fi rst 3 d. Applications inhibited (50%) the relative nitrifi cation rate and increased (50%) hot-water-soluble carbohydrates in the soil at the highest rate. No effects were observed on soil microbial biomass C (114-205 mg kg-1) and activity (5-8 mg CO2-C kg-1 d-1) or on corn grain yields (6349-7233 kg ha-1). Controlled land application seems to be a viable alternative for landfi ll leachate management, but NO3 - leaching, NH3 volatilization, and accumulation of salinizing ions must be monitored in the long term to prevent environmental degradation. © American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America.

During the start of his career, author and psychotherapist Vacir de Souza realized the lack of organized collection of topics and exercises that will cover the full spectrum of problems clinicians must deal with. The difficulty of facilitating group psychotherapy without material was experienced by de Souza and observed the challenge of clinical documentation. These existing gaps and limitations were bridged by de Souza by writing and publishing a series of books, one of which is “Group Psychotherapy: Exercises at Hand—Volume 3” (published by iUniverse). The author designed a group session model - a unique, customizable ready-to-use model that greatly helps in the work of any psychotherapist such as in the professional documentation and records of patients. This third book of the series, published in 2011, gives a concise, creative and systematic approach for group psychotherapy sessions that would aid psychotherapists and counselors. “Group Psychotherapy: Exercises at Hand—Volume 3” provides innovative topics and exercises meticulously created and organized in a logical sequence. “This book provides group session models with criteria and guidance for the patient documentation and records. It provides valuate suggestions for group interactions, therapeutic interventions, techniques and treatments,” the author describes his book. “The book also contains a collection of several funny pictures with captions and matches the content of each handout. They help patients to better connect and relate to the topics, bring a humoristic environment, and help with the group climate.” “Group Psychotherapy: Exercises at Hand—Volume 3” By Vacir de Souza, LMHC, CAP Softcover | 8.25 x 11 in | 260 pages | ISBN 9781450278461 E-Book | 260 pages | ISBN 9781450278478 Available at Amazon and Barnes & Noble About the Author Vacir de Souza, LMHC, CAP is a psychotherapist and addiction counselor at Camillus Health Organization in Miami, with over 20 years of group therapy experience. He received his bachelor’s degree in psychology from Universidade Estadual de Londrina in Brazil and his master’s degree in counseling education from Florida International University.
