“…The authors observed that the application rate of 8% biochar reduced the residual effect of metribuzin and provided increased germination of Palmer amaranth (Amaranthus palmeri), being larger than the unamended soil. The reduction in herbicide residual effect was also observed by [92], in which an application rate of only 1.6% of bonechar in the soil was sufficient to reduce the level of weed injury by 50%.…”

Pyrolysis temperature and application rate of biochar to soil can influence herbicide behavior and soil fertility. The objective was to investigate the effect of soil amendments with application rates of sugarcane straw biochar, produced at different pyrolysis temperatures, on the sorption–desorption of metribuzin in soil. The analysis was performed using high-performance liquid chromatography (HPLC). The treatments were three pyrolysis temperatures (BC350, BC550 and BC750 °C) and seven application rates (0, 0.1, 0.5, 1, 1.5, 5 and 10% w w−1). Amended soil with different application rates decreased H + Al and increased pH, OC, P, K, Ca, Mg, Fe, Mn, CEC and BS contents. Kf values of sorption and desorption of metribuzin were 1.42 and 0.78 mg(1−1/n) L1/n Kg−1, respectively, in the unamended soil. Application rates < 1% of biochar sorbed ~23% and desorbed ~15% of metribuzin, similar to unamended soil, for all pyrolysis temperatures. Amended soil with 10% of BC350, BC550 and BC750 sorbed 63.8, 75.5 and 89.4% and desorbed 8.3, 5.8 and 3.7% of metribuzin, respectively. High pyrolysis temperature and application rates of sugarcane straw biochar show an ability to immobilize metribuzin and improve soil fertility, which may influence the effectiveness in weed control.

“…However, this positive effect on the remediation of contaminated soils may negatively influence the agronomic efficacy of metribuzin in the soil, reducing the control of weed seed banks. The fact that biochar can reduce herbicide efficacy is not a desired effect, as it may require an increased herbicide dose to achieve similar levels of control as in soil not altered by biochar, increasing production costs and potential environmental risk [ 46 ]. Therefore, it is important to understand the physicochemical characteristics of biochar, soil, and herbicides, as well as the possible interactions between these factors, in order to achieve satisfactory recommendations and functionality of biochars as fertilizer sources and herbicide sorbents without posing an environmental risk.…”

Biochar-amended soils influence the degradation of herbicides depending on the pyrolysis temperature, application rate, and feedstock used. The objective of this study was to evaluate the influence of sugarcane straw biochar (BC) produced at different pyrolysis temperatures (350 °C, 550 °C, and 750 °C) and application rates in soil (0, 0.1, 0.5, 1, 1.5, 5, and 10% w/w) on metribuzin degradation and soil microbiota. Detection analysis of metribuzin in the soil to find time for 50% and 90% metribuzin degradation (DT50 and DT90) was performed using high-performance liquid chromatography (HPLC). Soil microbiota was analyzed by respiration rate (C-CO2), microbial biomass carbon (MBC), and metabolic quotient (qCO2). BC350 °C-amended soil at 10% increased the DT50 of metribuzin from 7.35 days to 17.32 days compared to the unamended soil. Lower application rates (0.1% to 1.5%) of BC550 °C and BC750 °C decreased the DT50 of metribuzin to ~4.05 and ~5.41 days, respectively. BC350 °C-amended soil at high application rates (5% and 10%) provided high C-CO2, low MBC fixation, and high qCO2. The addition of low application rates (0.1% to 1.5%) of sugarcane straw biochar produced at high temperatures (BC550 °C and BC750 °C) resulted in increased metribuzin degradation and may influence the residual effect of the herbicide and weed control efficiency.

This study aimed to determine the level and extent of financial literacy of personnel in the Department of Education, District of Subic, Zambales. This study is limited to one hundred fifty-eight (158) personnel in the selected schools in the district of Subic. In this study, descriptive research design was adopted. The researcher utilized a self-made survey questionnaire in gathering the data vital to this study. The data gathered from the self-made survey questionnaire were tallied, tabulated, and interpreted accordingly to the following statistical tools: Frequency and Percentage Count, Weighted Mean, Likert Scale and Analysis of Variance. From the given findings, the following conclusions were drawn: First, majority of the respondents were female, age 30-39 years old, bachelor’s degree holder, 0-5 years in service, currently in the teaching position and have no training on financial literacy. Second, the respondents were found to have an awareness of their personal financial literacy in terms of financial management, budgeting, investing and savings. Third, it is also found out that the respondents were aware of their personal extend of the financial literacy skills in terms of trainings and seminars, adherence to policy and their behavior towards financial literacy. Fourth, it was also found out that there was a significant difference in the level of financial literacy of the respondents when grouped according to profile variables highest educational attainment and position. Fifth, there is a significant difference on the extent of financial literacy when grouped according to profile variable sex and highest educational attainment. The length of service has a significant difference only on the adherence to policy. Lastly, based on the results of the study, the researcher may recommend a training program to enhance the financial literacy of the respondents. In the light of the findings of the study, the following recommendations were made: 1.) The DepEd Subic District may implement awareness on what is important in financial literacy to their personnel; 2.) the respondents may strengthen their budgeting and investing skills through attending related training offered by the division of Zambales; 3.) the respondents may improve their financial literacy extent through attending trainings and seminars and develop their financial literacy behavior; 4.) DepEd Division of Zambales administrators may ensure the inclusions of financial management, budgeting, investing and savings on the training to improve the level of financial literacy of personnel; 5.) the teaching and non-teaching personnel financial literacy and financial behavior may be improved through attending various trainings and seminars; 6.) the researcher may recommend or propose a training program to enhance the financial literacy of the DepEd personnel; 7.) a replication of this study in other districts within the division of Zambales is suggested for further research.
