Effects of long-term applications of high rates of animal manure on plant-availability of nutrients, especially micronutrients, have not been adequately addressed. Our study indicates high rates of P applied via manure do not suppress uptake of Cu and Zn by barley but, at higher than recommended manure rates, uptake of Ca may be inhibited, perhaps through increased salinity.

Manure Application

Although much of the manure in Canada is surface applied to forages, little research exists evaluating time of year (Time) and rate (Rate) of its application on forage yield and nutrient uptake. Field trials (10 yr) on two soils (sandy loam upland and silty clay loam dykeland) investigated this. Experimental arrangement was a factorial [Time (spring, summer, early and late fall manure applications)] plus control [spring applied ammonium nitrate fertilizer (ANF)] in a Latinized split plot. ANF at 0, 25, 50, 100 and 200 kg N ha-1; 0, 75, 150, and 300 as semi-solid beef (SSM) and 150 kg N ha-1 as liquid dairy manure (LDM), constituted respective splits. The Time X Rate interaction, later in the trial on the upland soil, showed higher yields and nutrient uptakes with fall manure application. There was little interaction on the dykeland soil; summer application resulted in higher yields at times. For both soils, optimal long-term application rate of SSM was approximately 150 kg N ha-1 while that of ANF was approximately 100 kg N ha-1. Inherent fertility of dykelands resulted in flatter responses to manure addition. Negligible and significant residual N occurred with fertilizer and manure, respectively. Nitrogen, phosphorus, potassium, calcium, magnesium, manganese, copper, zinc and boron uptake was due to amendment impact on yield. Recommended is 150 kg N ha-1 of SSM or LDM applied in fall and summer to Maritime grasslands grown on upland and dykeland soils, respectively. Yield differences may not warrant producers adjusting timing of in-season manure application.

Long Term Studies

To monitor the development of four community-managed forests, networks of permanent sample plots were established in 2005 at sites in Chitwan, Kaski and Mustang Districts, Nepal. This research note documents the procedures used when preparing for establishment of the plot networks, evaluates the applied stratification of the forest on the basis of data gathered in pilot surveys conducted in the early 2005, and provides a discussion on the implications of the choices made. Key words: Community-managed forests; permanent sample plots; stratification; allocation; estimates Banko Janakari Vol.16(2) 2006 pp.3-11

The Impact

Adolescents experience alarmingly high rates of sexual violence, higher than any other age-group. This is concerning as sexual violence can have detrimental effects on teens’ personal and relational well-being, causing long-term consequences for the survivor. Still, adolescents are hesitant to report the assault or seek out services and resources. When an adolescent survivor does seek out services, they may interact with a provider who is a mandatory reporter. This scoping review sought to synthesize the current U.S.-based research on the role, challenges, and impact of mandatory reporting (MR) in the context of adolescent sexual assault. Database searches using key words related to MR, sexual assault, and adolescence identified 29 peer-reviewed articles. However, none of these articles reported on empirical investigations of the phenomenon of interest and instead consisted of case studies, commentaries, and position papers. The scoping review was expanded to provide a lay of the land of what we know about the intersection of adolescent sexual assault and MR. Results of the review indicate that though implemented broadly, MR policies vary between individuals, organizations, and states and have historically been challenging to implement due to this variation, conflicts with other laws, tension between these policies and providers’ values, and other factors. Based on the available literature, the impact of MR in the context of adolescent sexual assault is unknown. There is a critical need for research and evaluation on the implementation and impact of MR policies, especially in the context of adolescents and sexual violence.

Cesium 137

Soil erosion may be difficult to quantify from redistribution of 137Cs at sites where stubble-mulch techniques were adopted prior to 137Cs deposition, because appreciable 137Cs may have been transported before it was mixed into the soil Ap layer. We present evidence that this occurred in two long-term cropping experiments in southern Alberta. Key words: Cesium-137, tillage, long-term crop rotations, fallow
