Environmentally Friendly Slow Release Nano-Chemicals in Agriculture

Abstract

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.

Effect of Spraying Nano-Silicon in some Growth and Yield Traits For Two Oats Cultivars

“…Nanoscale substrates and particles have a high surface area and may maintain a large number of atoms or molecules because of their small size. Included among them are nutrients that are delivered gradually, are readily absorbed by the plant, and have a low environmental impact [5,6]. The application efficiency of nanofertilizers is increased by an average of 18-29% compared to that of traditional mineral fertilizers because they enhance plant metabolism and nutrient absorption through nanopores.…”

Effect of Spraying Some Bio-and Nano-Stimulants Fortified with Potassium on the Growth and Yield of Rice

“…Biostimulators are any organic matter such as amino acids fortified with Macro and Micro elements, plant extracts, seaweed and hormones or micro-organisms used with plants for the purpose of improving nutrition efficiency, crop quality and tolerance to abiotic stresses are used as a spray on plants or added to the soil regardless of the nutrients they contain [1].Potassium is also one of the elements that play important roles in plants, including in regulating the osmotic effort of plant cells , It enters the process of opening and closing stomata and activates more than 80 enzymes responsible for the representation of nitrogen, energy and respiration [2,3]. The nano-stimulators that have been developed are nutrient carriers with nanoscale dimensions ranging from 1-100 nm, Nanoparticles are characterized by a high surface area and a high ability to retain nutrients with a high stabilization 1060 (2022) 012036 IOP Publishing doi:10.1088/1755-1315/1060/1/012036 2 liberation that facilitates the absorption of nutrients [4].Nanomaterials stimulate many vital aspects of plants and both the leaf surface and plant root are gateways for key plant nutrients that are easily penetrated by nanomaterials [5].In plants, amino acids are combined with each other to form proteins and various peptide compounds or they are freely present. There (20) amino acids are freely present in the plant tissue.…”
