Soil pollution has become a major threat to food safety, human health, and ecological safety. A series of soil contamination events such as poisoned rice, cadmium contaminated rice, land poisoning and lead poisoning have led to social instability and even public panic in some areas. Soil pollution management faces huge challenges and problems such as lack of rules and regulations, ambiguity of responsibility, lack of accountability, and poor management ability. The first task to meet the challenge of soil pollution is to prepare the soil law to provide the legal basis for soil environment management and soil pollution management. To manage soil pollution and to meet current and future needs, soil pollution management requires the creation of an integrated standard system of soil environment based on the basic design principles of protection of human health and ecological safety. Pollution management mainly involves two important issues: creating a clear system of responsibility that determines the responsibility of cleaning up contaminated sites, and establishing a fund dedicated to these areas. Soil pollution management requires a multifaceted, organized, and long-term effort. The enactment of soil law can only meet the basic need to strengthen or improve soil pollution management. Soil law cannot solve all problems. Therefore, it is important and necessary to improve effective mechanisms for soil pollution management, although to date, emphasis has been placed on research, classification, risk assessment, and remediation of contaminated sites.
 

Agriculture has become the primary source of water pollution. Unsustainable agriculture is a severe problem for water quality. Changing agricultural policies toward sustainable growth is imperative, which will lead to the development of many new techniques and methods of integrated resource management to eliminate agricultural pollution. Soil is a limited resource that must be well managed to meet current needs without compromising the ability of future generations to meet their own needs. Harvesting agricultural soil for sale is a crime. This study aims to identify the main hazards on the farm and provide simple, practical solutions for use on the farm. The results of the research are based on the suggestions of farmers and experts in the literature. The results show that soil loss, either through mineral imbalance or erosion, is the greatest threat to agricultural productivity. Soil erosion by wind and water is the primary process of surface soil loss. Proper management measures can reduce soil losses, increase soil organic matter, improve soil physical properties, and conserve water resources.

There are many things on the farm to improve waste management and reduce resource consumption. This research aims to identify the existing cases and how to manage them. The research is a library study in which the subject literature has been reviewed. The research results show that farm management at first requires the development of rules and regulations, and in the next step, farmers are required to comply with those rules and regulations. The proposed waste management approach is 1) avoidance, 2) reduction, 3) reuse, and 4) recycling. Among the items studied in the research are pesticides and chemical fertilizers for sewage sludge, crop residue, waste, packaging materials, hydraulic oils, and water consumption. Among the things that farmers must observe is to reduce the use of pesticides and chemical fertilizers and not to use non-standard sewage sludge. They should also refrain from burying waste in agricultural lands. The remaining containers of pesticides must be collected and recycled. Hydraulic oils should only be burned in special machines. Packaging should be done using biodegradable containers. Also, prohibited pesticides should not be used because of their environmental hazards to humans and wildlife.
