Controlled Release Fertilizers

Agriculture is important for people all over the world in order to obtain food to sustain the ever-growing population. However, the current practices for obtaining more and more food has several environmental challenges. Hence, new environmentally friendly fertilizers, herbicides, and pesticides have been developed that enhance crop yield by facilitating maximum nutrient uptake by the application of nanotechnology that will help in promoting sustainable agriculture by the slow or controlled release fertilizers. This slow discharge encourages improved delivery of nutrients to the plants that further speeds up early germination, fast growth, and high nutritional level. The current study is aimed to review nano-chemicals used in agriculture that have been developed by the researchers all over the world.

Phosphorus Fertilizers

Controlled release of P was investigated with barley plants grown on two soils. Phosphorus fertilizers (monoammonium phosphate [MAP], diammonium phosphate [DAP] and ammonium polyphosphate [APP]) were dissolved in water and were applied full dose at sowing; 1/22 dose every 2nd day and 1/4 dose each 11th day. Uptake of fertilizer P in barley was much greater when the P was applied every 2nd and 11th day compared to only the day of sowing.
