Chitin can be used as a soil conditioner in order to boost soil quality, plant growth, and plant resilience . Chitin, a biodegradable polymer extracted from crab or shrimp shells, is used to produce chitosan . Soil treated with shrimp waste chitin and/or chitosan has been shown to temporarily increase root growth (for example, in tomatoes) and decrease root nematode infection . Wheat and potato crops benefit greatly from the use of chitin/chitosan biofertilizers during their vegetative stages of growth . Additionally, wheat is a crop that needs more phosphorus, so one of the key measures to improve the efficiency of phosphorus fertilizer, reduce the cost of fertilization, and promote high-quality and high-yield wheat is the scientific application of phosphorus fertilizer. Fertilizers are often referred to by their phosphate content. Phosphates are also found in many pesticides used to kill common insects like mites and aphids. If the wheat mosaic virus is hiding on chitin/chitosan (or cellulose) in the soil or on insects, phosphate fertilizers or pesticide dilutions with phosphates could release it. Because of this, the likelihood of the wheat mosaic virus spreading via soil or insects has greatly increased.
