Agricultural lime is used as a gentle pesticide by many farmers and gardeners thanks to its less corrosive properties. Agricultural lime consists of limestone that has been crushed and mixed with water so that it can be more easily distributed. There is less danger of burning with this form of lime and it can be applied directly to foliage.
Lime is a corrosive base mineral that is most commonly used as a cement additive. Lime is also a useful and natural pesticide and fungicide with proven benefits for plants and crops. Whenever lime is being used, work gloves, goggles and a face mask should be worn for protection.
The use of lime as a soil treatment can have several beneficial effects for plant life. Lime lowers the acidity of soil and in doing so can raise the yield of a crop and improve the health of a given plant species. Healthier plants are less susceptible to pests and disease and while it does not kill or repel these threats directly, lime soil treatments do allow plants to better defend themselves against pests of all kinds. Use a pH test kit to determine the acidity levels of your soil and whether or not lime spreading is necessary. Apply the appropriate lime compound for your crop and soil needs according to the manufacturer's instructions.
