This study was conducted to assess the micronutrient status of soils under three different management practices at the Nigerian Institute for Oil Palm Research (NIFOR), Benin City, Edo State, Nigeria. Soil samples were collected from three different fields Research (NIFOR), Benin City, Edo with different management practices. The samples were air dried and analyzed for Fe, Zn, Cu, and Mn contents using standard method. Data was subjected to ANOVA and correlation studies. Result showed that soil micronutrient status was generally low as revealed by their estimated levels of availability: field 53 (Mn = 0.0333; Zn = 3.723; Cu = 2.04; Fe = 6.4), field 56 (Mn = 0.0367; Zn = 3.737; Cu = 1.12; Fe = 7.0939), field 71 (Mn = 0.0167; Zn = 3.860; Cu = 2.89; Fe = 7.243). Fe and Zn were above critical level for the 3 fields. Mn was below the critical level for the 3 fields and was significantly higher in field 56 (Orlu and Kulfo series) (p≤ 0.05). They were all similar. Fe was significantly different in field 53 (Kulfo and Alagba series) but similar in fields 56 and 71 (p≤ 0.05). Cu was significantly different in the 3 fields tested with field 71 (Orlu and Alagba series) higher than the critical level. Correlation studies showed that pH had a positive and significant correlation with Fe and Zn as observed in fields 71 and 56 (r = 0.9934, P≤ 0.05) and (r = 0.9997, P ≤ 0.05) respectively. Cu was the only micronutrient that has correlation with clay on each of the fields: 53, 56 and 71 (r = 0.9929, P≤0.05) (r = 0.9988, P≤ 0.05) and (r = 0.9967, P ≤ 0.05) respectively. Strong correlation existed between clay and Fe in field 53 (r = 1, P≤ 0.05). The concentration of the micronutrients (Fe, Mn,Zn Cu), in field 53 were not extreme (neither the highest nor lowest) when comparing the three fields indicating that BMP (Best Management Practice) may be the best for maintaining good micronutrient level in soils supporting oil palm. Fields 53 and 56 is adequate in Fe and Zn but not adequate in Mn and Cu while field 71 was adequate in Zn, Fe, and Cu but not in Mn. Based on the result of this experiment, adequate fertilizers of these micronutrients as their respective sulphates or impurities should be added to maintain proper micronutrient level.

Abstract Passage of the Clean Water Act (CWA) of 1972 prompted states to invest significant resources to develop programs to control nonpoint source (NPS) pollution from forestry and other activities. Forestry-related agencies and organizations have since developed silvicultural best managementpractice (BMP) guidelines to reduce NPS pollution, maintain stream integrity, and meet state water quality standards. To determine the effectiveness and implementation level of best management practices (BMP) on public and private forestland, states further developed and implemented theirBMP compliance monitoring programs. This study documents the similarities and differences in efforts, methods, resources, and expenditures among BMP compliance monitoring programs across the 13 southern states. 29(1):48–52.

Yield And Quality

Demand for high quality oat (Avena sativa L.) for consumption by humans and race horses has increased, leading to increased oat production on the Canadian prairies. Little information exists on the best management practices for producing high-quality, high-yielding oat using direct seeding systems and cropping practices developed and adopted over the past 15 yr. The objective of this study was to determine the effect of early seeding on grain yield and quality of oat cultivars currently grown in the eastern prairie region. Four seeding dates and four cultivars were tested at Indian Head, Melfort, and Brandon over 3 yr. Moving the seeding date from mid-June to early May increased oat yield, seeds per panicle, kernel weight, test weight and plump seed by 76, 33, 10, 13 and 11%, respectively, when averaged across all locations and years. This increase in yield and quality was probably due to improved environmental conditions and a reduction in crown rust infection (Puccina coronata Corda). Crown rust has a larger effect on seed yield and quality as one moves east and south from Melfort, Saskatchewan, and as seeding was delayed from early May. Early seeding of oat decreases the risk of obtaining low yield and/or quality, and should be considered a best management practice for growing milling oats, especially in the southeastern prairies of Canada.

State Forestry

State forestry best management practice (BMP) programs have been widely developed and implemented to prevent nonpoint source water pollution in the past three decades. The unanswered question is how forestry BMPs have affected the welfare positions of consumers, mills, loggers, and forest landowners. A Muth-type equilibrium displacement model was constructed to examine welfare changes of these stakeholders. The model considered a two-stage vertical production system with variable proportion production technology and imperfect market structure. Industrial mills experienced little welfare loss from forestry BMP regulation. Consumers had the largest absolute welfare loss, and loggers had the largest relative welfare loss in the base scenario. The supply elasticity of harvesting services had the greatest impact on the relative incidence of welfare losses between landowners and loggers, and in the long run their welfare losses were comparable. These results may help to improve future state forestry BMP guidelines and design incentive systems for increasing implementation rates.

Decision Making Processes

Best management practices (BMP) are defined in the United States Clean Water Act (CWA) as practices or measures that have been demonstrated to be successful in protecting a given water resource from nonpoint source pollution. Unfortunately, the greatest majority of BMPs remain unvalidated in terms of demonstrations of success. Further, there is not a broadly accepted or standardized process of BMP implementation and monitoring methods. Conceivably, if standardized BMP validations were a possibility, practices would be much more transferrable, comparable, and prescriptive. The purpose of this brief communication is to present a generalized yet integrated and customizable BMP decision-making process to encourage decision makers to more deliberately work towards the establishment of standardized approaches to BMP monitoring and validation in mixed-use and/or municipal watersheds. Decision-making processes and challenges to BMP implementation and monitoring are presented that should be considered to advance the practice(s) of BMP implementation. Acceptance of standard approaches may result in more organized and transferrable BMP implementation policies and increased confidence in the responsible use of taxpayer dollars through broad acceptance of methods that yield predictable and replicable results.

PurposeThe purpose of this study is to use the framework of stakeholder analysis in a participatory democracy, used in forest management planning, for arriving at the best management option for selected sacred groves of Kachchh. This is achieved by accounting for economic, cultural and ecological values and the resulting outcomes in the complex institutional mechanism. Additionally, this study provides a framework for complex decision-making that characterizes the management of sacred groves involving multiple criteria and options accounting for multiple stakeholders that involve conflicting interests.Design/methodology/approachThe analytical hierarchy process was used to calculate the global priorities of management options using the relative importance of stakeholders, weights of different decision criteria to arrive at the best management practice for selected groves of Kachchh. The global priorities of management options rank management practices based on stakeholders' values and their effects on the choice of management strategy as well as on the potential to attain a compromise between competing interests. For this purpose, survey responses of 141 individuals belonging to seven different stakeholder categories were analyzed. Along with focus group discussions, and personal interviews, a stratified random sampling technique was used to survey respondents.FindingsBased on the global priority weights of the alternatives, it is determined that the restoration management option (guggal is restored by planting new guggal sapplings, cattle grazing is prohibited and high levels of ecosystem goods and services are provided) had the highest score, followed by the preservation management option (grazing is allowed on the periphery, juvenile guggal is preserved and moderate ecosystem goods and services are provided). Therefore, restoration of sacred groves is the best management practice of sacred groves in West Kachchh, offering a compromise between maximizing provision of ecosystem services and economic benefits in terms of allowing cattle grazing.Originality/valueThough there are several studies on best management practices for community-owned forests, irrigation systems, and pasture lands, and the role of local institutions in sustaining these common-pool resources; such studies for sacred groves are absent, despite sacred groves being one of the longest surviving common-pool resources that has sustained it over several decades. This is the first study that uses the framework of stakeholder analysis to arrive at the best management practice for sacred groves. The uniqueness of the study lies in a comprehensive evaluation of ecological–economic–cultural interests of multiple stakeholders toward management of sacred groves.

Implementation Guidelines

Phosphorus fertilizer spill prevention is a Best Management Practice (BMP) approved by the South Florida Water Management District (SFWMD), one designed to reduce drainage P loads in the Everglades Agricultural Area (EAA). Spill prevention of P fertilizers is a BMP that is widely implemented by growers in the EAA. This BMP is easily implemented and can have an immediate impact on reducing off-farm P loads. This EDIS document is part of a series of publications that provide current implementation guidelines for commonly employed farm-level BMPs designed to reduce P loads from farms located within the EAA basin. This document is SL231, one of a series of the Department of Soil and Water Sciences, UF/IFAS Extension. Original publication date September 2005. SL231/SS450: Best Management Practices in the Everglades Agricultural Area: Fertilizer Spill Prevention (ufl.edu)
