With traditional spraying techniques, workers wear knapsack sprayers that are either run by heavy batteries or manually pumped. Tractor-driven boom sprayers and airplanes incur extra time and expenses for spraying the entire crop field. These methods also often over-apply fertilizer and pesticide leading to unwanted waste and run-off. Yet, crops need consistent spraying and foliar fertilizer applications to maintain quality yields. Farmers now take advantage of drones to spray specific plants and areas for treatment, saving money from overfertilizing during the growing season. Similarly, drones are capable of spraying herbicide and pesticide in the identified problem spots. COTS drones make spot spraying easier, more cost-effective, and cheaper than any other existing method.
Finding pests, diseases, and stresses in field crops rely on physical scouting. These methods are not only expensive but time-consuming, as farmers can pay high consultancy costs to have an expert visit their crop fields. Drones get high-resolution aerial imaging by flying at low-altitude and help detect pests and diseases much earlier and more quickly. Drones can observe individual plants or branches of a tree that carry sign of disease or pests. This information also makes it easy for the growers to make precise decisions about treatment during infestations.
Soil imaging is crucial for getting soil and field conditions during planning, growing, and harvesting. This data could yield useful insights on soil quality, fertility, soil nutrient deficiencies, and pH conditions across the site. Samples are collected from the field and analyzed in the laboratory through expensive and time-consuming techniques. With recent advances in technology, drones with special sensors allow for on-demand measurements quickly. Information can include soil pH, texture, topology and minerals like Nitrogen, Phosphorus, Potasium, Calcium, etc. . . These analytics help farmers determine the best planting patterns and treatments to get a higher yield per acre.
