Normalized difference vegetation index and soil color-based management zones in irrigated maize
Spectral vegetation indices such as the normalized difference vegetation index (NDVI) have been shown to be useful for indirectly obtaining crop information such as photosynthetic efficiency, productivity potential, and potential yield. The objectives of this study were (i) to examine the relationships among NDVI determined early in the growing season, soil color-based management zones (SCMZ), ...

Predicting Shiraz Yield to 95% accuracy in Barossa, Coonawarra and the Hunter Valley
Yield prediction of grapes to date has so far been anyone’s guess. In-field estimates, even on the week of picking, can have an error of up to 30% from the actual tonnage. With the variability in weather conditions causing bumper and bust yields for the past few seasons, it’s been extraordinarily difficult to give accurate estimates for winery production. To predict yield, ...

Tackle Vineyard Variability with Vine Health Predictions
Variability in vine vigour and grape composition makes it difficult for growers to meet uniform quality specifications from winemakers. As a result, growers often have the opportunity to make up to AU$2,155 per hectare for reducing variability. Vineyard variability is driven by climate, features of the land (e.g. topography and soil composition, including moisture content and nutrient ...

Farmonaut For Crop Area and Yield Estimation
INTRODUCTION: CROP AREA ESTIMATION The two components of agricultural production estimation are crop area and yield estimation. In order to estimate yield, Producers generally measure the amount of a particular crop harvested in a sample area to estimate crop yield. The harvested crop is then weighed, and the entire crop production of the area is approximated from the sample. A method for ...
