INTRODUCTION

ORGANIC FARMING

CONVENTIONAL FARMING

Around the world, the dependency on land and other natural resources is inevitable to meet human needs and long term survival. Since the past decade, organic farming was promoted and adopted by the government as a way for maintaining a sustainable agriculture due to its less dependent on external factors. In the eleventh Malaysian Plan (20162020), the focus of the government include promoting the agro-food subsector in order to achieve the targeted sufficiency level of key food commodities. In contrary, conventional farming has been a common practice among farmers in improving productivity to meet the increasing demand. However, this form of farming has been dependent on the high usage of synthetic fertilizers, pesticides and herbicides that has raised pertinent environmental concerns which affects the biodiversity (Lupwayi et al., 2001). This method is based on the research conducted by Jenkins et al., 2010; Gasparatos et al., 2011 and Arnhold et al., 2014.

Organic farming is a form of agriculture that relies on sustainable techniques to enhance the natural fertility of a farm, including crop rotation, companion planting, biological pest control, and naturally-sourced fertilizers such as compost, manure, green manure, and bone meal. Pest-control measures such as mixed crops and fostering natural insect predators, are employed, while it excludes the use of synthetic petrochemical fertilizers and pesticides, plant growth regulators such as hormones, antibiotic use in livestock, genetically modified organisms, human sewage sludge, and nanomaterial. The agricultural approach emphasizes sustainability, openness, independence, health, and safety.

A crop can be classified as conventional if synthetic chemicals are used to maintain the plants. A significant amount of chemical and energy input is required in conventional agriculture to produce the highest possible yield of crops. Conventional agriculture was developed to make farming more efficient, but achieves that efficiency at a major cost to the environment. The goal of conventional agriculture is to maximize the potential yield of crops. This is achieved through the application of synthetic chemicals, genetically modified organisms, and a number of other industrial products. Production of these crops is beneficial to nothing but food security and economy. Since the goal of conventional agriculture is to maximize yields, environmental health and biodiversity are usually not preserved.

The environment benefits because natural habitats are less threatened The soil can be in better condition because of the manure used It can provide healthier food for people The industry is worth over £1 billion a year BBC UK

More produce is damaged by pests Weed control is time consuming as weeds are often removed mechanically Organic dairy farms produce more methane per animals than non-organic due to the diet of the cattle Some organic farming methods use more water than conventional farming The crop yield is lower on organic farms (about 20% less compared to conventional farming
