Resumen
Non-chemical agricultural methods can improve soil health, conserve ecology and enhance biodiversity, and are more sustainable. Media messages trigger a change in farmers’ attitudes that needs to be studied to understand their practices. This study used the Diffusion of Innovation theory to figure out how farmers accept chemicals in farming practices from the media and how the chemicals impact the environment. The objective is to understand how media influence farmers towards chemical fertilizers and pesticides, to find out which media has been widely used by farmers, and to find out which the

Resumen
Agricultural chemicals may have an adverse impact on environment and food safety. The demand prices of such chemicals reveal farmers’ willingness to pay and their preferences. This article examines the determinants of the agricultural chemicals price in the export-oriented vegetable production area, Anqiu, Shandong Province, applying the Hedonic Price Model based on the spatial econometric technique to analyze the price. We find that the agricultural chemicals with a different shape and function have different equilibrium prices, and the chemical attributes of permeability, rainfastness, being

Climate change is likely to affect the nature of pathogens/ chemicals in the environment and their fate and transport. We assess the implications of climate change for changes in human exposures to pathogens/chemicals in agricultural systems in the UK and discuss the effects on health impacts, using expert input and literature on climate change; health effects from exposure to pathogens/chemicals arising from agriculture; inputs of chemicals/pathogens to agricultural systems; and human exposure pathways for pathogens/chemicals in agricultural systems.

Resumen
A growing segment of society is concerned about a myriad of health and environmental issues related to the use of pesticides and other agricultural chemicals. Despite the leveling-off of agricultural chemical use in the 1980s, chemical use in agriculture has come to be seen as a two-edged sword. On the positive side, agricultural chemicals have become the engine for world-wide productivity gains. These chemicals have contributed to increased yields per acre and have reduced waste in storage and distribution. On the negative side, agricultural chemicals are perceived by many to present risks to

Three combined investigations were conducted to examine the sources of PM2.5 in agricultural areas. The first was the measurement of PM2.5 and gaseous compounds in the greenhouse, which is a relatively closed system, while the second was the analysis of pesticide components used in agricultural areas. Finally, the physical and chemical properties of PM2.5 were analyzed in an orchard area and compared with the results of the greenhouse and agricultural chemical analyses. As a result, this research was able to confirm the source of emission and characteristics of PM2.5 originating from the agric

Widely used in the agricultural sector, they are designed to fight plant diseases, pests, insects, weeds and other harmful organisms. Pesticides are chemical or biological substances used to prevent or reduce the damage of harmful organisms to plants, humans and animals. For example, arsenic powder and sulphur were among the first pesticides used to control insects and pests during these periods. The most important reason for this is that natural organic and inorganic substances used as pesticides have been replaced by synthetic substances due to their disadvantages such as being unstable and

The overall theme of this project was to increase the speed of analysis for monitoring pesticide residues in food. Traditionally, analytical methods for multiple pesticides are time-consuming, expensive, laborious, wasteful, and ineffective to meet critical needs related to food safety. Faster and better methods were needed to provide more cost-effective detection of chemical contaminants, and thus provide a variety of benefits to agriculture.

Resumen
The extensive use or non-specific, hazardous, chemical insecticides demands the development of "healthier" alternative means for pest control. Insect-specific, baculoviruses expressing anti-insect toxin genes (from mites or scorpions) demonstrated in laboratory assays and field trials enhanced insecticidal activity and provided some protection from lepidopterous larvae to agricultural plantations. To utilize recombinant baculoviruses as commercial biopesticides in row crop agriculture, further increase in their speed of kill should be achieved and the reduction in crop damage should be compara

Resumen
The recipe’s in this book are put together to highlight integration in sustainable agriculture at the IIHS Kengeri Campus, emphasizing mixed cropping as a key practice for enhancing biodiversity, soil health, and food security. The campus utilizes agro-ecological methods that reduce reliance on chemical inputs while promoting resilience through intercropping, organic composting, and integrated pest management. The agricultural plots at the campus are cultivated with millets, pulses, and oilseeds, demonstrating a sustainable model that supports both ecological balance and nutritional diversity.

Resumen
In the Cesar Department in Colombia, sustainable agriculture faces critical challenges despite its thriving livestock sector. Extensive cattle ranching and poor soil management worsen soil conditions. Additionally, significant environmental concerns arise from the substantial discharge of wastewater in the dairy processing industry. This study aims to valorize biosolids derived from wastewater during dairy plant disinfection to enhance sustainable livestock production. It explores the use of biosolids as the primary matrix for creating composted compounds and biopolymers for agricultural purpo

Resumen
Preferential flow is the process whereby water and solutes move by preferred pathways. During preferential flow, local wetting fronts propagate to considerable depths in the soil profile, essentially bypassing the matrix pore space. Under such conditions classical methods, such as the convective-dispersive equation, for quantifying flow of water and solutes in uniform soils are not valid. This project set out to develop methods to predict fast and early breakthrough of solutes. To facilitate understanding of these processes, several field drainage studies were conducted in the United States an
