These in turn can be used to create specific prescription maps to optimise field inputs and returns.

Utilising latest analytic software available, AGree consultants are able to produce field management zones created from historical and current data using information such as yield data, imagery and soil sample data.

These in turn can be used to create specific prescription maps to optimise field inputs and returns.

Variable rate maps can extend to

Nutrient replacement maps (Nitrogen, Phosphorus etc.)
Manure and clay spreading application maps.
Lime and gypsum application maps.
Spray application maps (insecticides, herbicides, fungicides, moluscicides, baiting).
Soil cultivation improvement (deep ripping, delving) maps.
Seeding rate maps


Everything that happens in a field should be recorded with spatial attributes. This means that every farm operation, whether it affects the entire field, part of the field or a point within the field, it should have a latitude and longitude associated with it.

Various maps can be combined to create new information-based layers and reports that lead to better management decisions. For example, the combination of elevation, yield and weather information can be used to create a frost risk zone for hay cutting in the event of a frost.

Management Zones

Management zones can be easily created from existing layers of data, such as yield layers, field imagery, soil types, fertility classifications or tillage operations. Management zones can be used to aid decision-making throughout the season, to guide crop scouting and sampling and product applications.

Variable Rate Applications

Manage fertility in field by utilising nutrient surface maps and corresponding product application maps. Product application files can be exported to a number of different controllers. Beyond fertility, use information to create variable rate planting recommendations.
