To help tackle nutrient deficiency and plastic pollution in India’s soils, the country has one of the best knowledge delivery systems and trained human resource power in agriculture research. And yet, over 59 percent of the farming households receive no assistance from either their government or the private sector, according to the 2013 National Sample Survey conducted by the Indian government, the latest and most authoritative of its kind.

Sustainable agriculture means the production of food from plants or animals using different agricultural techniques that protect communities, the environment, and animal welfare. The extensive use of chemical pesticides and fertilizers to boost crop yields may have resulted in good yields and productivity, but it has caused the efficiency of the soil to deteriorate throughout the world day-by-day. This modern agricultural practice has caused a steep fall in the biodiversity (above and below the ground) associated with cropland ecosystems.
Researchers have successfully engineered bacteria to use nitrogen at night to create chlorophyll for photosynthesis. This new development could reduce the need for human-made fertilizers on agricultural crops, thus reducing the cost and manpower required for fertilizer application.
The adoption of fertilizer trees on farms is a simple and effective way to improve soil fertility, food productivity and therefore contribute to food security. Yet, there is still little empirical research that documents the impact of fertilizer trees on food security among smallholder farmer households. Researchers from the World Agroforestry Centre carried out a study in Malawi to analyze the impact of the adoption of fertilizer trees on food security among smallholder farmers

It is predicted that the population of China will stabilise at 1.6 billion within the next two decades. In order to feed this many people, crop production will need to increase by 2% each year to provide the estimated 580 million tonnes of grain that will be required. Mingsheng Fan and colleagues have published a review of past trends in agricultural production in China and the solutions that they think will allow China to produce more food in the future without an increase in available agricultural land. The main crops produced in large quantities in China are cereal crops, particularly wheat, maize and rice. The main limiting factors for the continued increase in agricultural production are water availability and soil quality. There is also the requirement to reduce use of nitrogen and phosphorus fertilisers because they pollute the air and water.
