Whether in the form of fertiliser, effluent, or other sources, the spreading of nutrients for soil maintenance and plant uptake is essential for majority of farming practices today. Excessive use of nutrients has also been identified as the key catalyst driving poor ground and surface water quality and because of this, governmental and regional bodies have enforced greater restrictions around where nutrients can be dispersed and at what quantities. Farmers and agricultural enterprises in Canterbury are now required to provide proof of placement of these nutrients when applying them to ensure there are no environmental management issues. The easiest way for companies to provide this evidence is to employ aerial mapping and surveying to identify current nutrient spread areas, risk water bodies, and other associated factors such as housing and neighbouring properties.
In this case scenario we’ve been tasked to map and survey a number of properties in the Canterbury region to provide this evidence in the form of accurate, high quality maps, that the farmer can use to identify these areas. Once created these maps can also be electronically exported and plugged into a variety of modern day machinery GPS systems to ensure the nutrient dispersal is applied to within the nearest centimetre of target application.
While the drones are in-flight, we survey each area by spraying GCP’s (Ground Control Points) and capturing the GPS values of these GCP’s using survey equipment. This data is used in conjunction with the captured imagery to ensure geographic accuracy is centimetre grade.
With the map imagery and survey data captured we can now move onto processing the data using modelling and GIS software. The end result is a high quality large scale printable map, an electronic interactive map, and a shapefile that can be added to machinery GPS for accurate spreading and proof of placement of the nutrient substance being applied. Using the shapefile, the machinery applying the nutrients will automatically shutoff over areas dictated by the map that are “risk” areas where nutrients may not enter, such as waterways, buildings, neighbouring properties, and other indicated buffer zones.
The farmer can now apply nutrients to their property with precision application and efficiency while remaining certain that their nutrient dispersal is going to comply with regional council requirements. The value attained in this precision mapping allows them to gain a new level of environmental and economic development across their farming system as well as an up to date excellent on farm map source.
