Due to increase in the population which is estimated that the human papulation will increased 9.7 billion in 2050. There is also increase the demands of the food productions. That’s why there is need to solve the problems regarding to the production of the food. Major problem of the food production is the shortage of the land due to the low and bad soil structure and quality of the soil. Soil erosion is one of the main issue which is caused due to the used of different chemicals, pesticides and fertilizers which are mainly used for the plant growth and protection but they are the main reasons of the production of the pollution in the soil. There is need of the different new technology for the improvement of the soil structure, quality, its fertility and decontamination of pollution from the soil which are eco-friendly to the environment and have no adverse effect. In this study the role of the different techniques in which genetic engineering, Nano technologies, soil and crop management strategies, integrated pest control management strategies, sustainable remediation techniques, microbial management strategies and the different management stairgates. All these techniques aim to the production of the plants and microbes which are effective against plant disease management. The aim of the use nano agrochemicals and nano sensors for sensing environmental and pathogen conditions against disease management. The aim of the paper to provide the production of the disease resistance plant and the provide balanced nutrients supplements to the soil for the improvement of the soil condition and its fertility. These techniques have economic importance due to the use of the nano agrochemicals which are low cost and have effective and reduce the use of the chemicals substances which have negative effect on the soil fertility.. There are sustainable remediations techniques also discussed which are used for the decontamination of the soil pollution. In this study the main focus on the improve and increase soil fertility which enhance the growth of the plants as well the production of the crop production. The production of the stress and degradation resistance microbes which is important factor for the protection of the soil from degradation or contamination. All the techniques which are used in this paper have no adverse effect they are helpful in the tolerance of the stress conditions.
