Introduction To achieve a more precise, ecological and economical pesticide application process, it is important to focus on crop parameters and field variability instead solely on disease occurrence. In fields with different soil quality, crops and water availability the amount of spray needed varies as well. For example, areas with a reduced cop growth need… read more »

Introduction With Precision Variable Rate Irrigation growers can record crop yields and make significant irrigation water savings. The need for uniform and accurate water delivery to the crop throughout its lifecycle is essential to maximizing yield and maintaining the health of the plant. Water is saved through matching irrigation rate to soil characteristics and avoiding… read more »
Introduction In intensive agricultural livestock production manure prevails regularly as a waste problem rather than an organic fertilizer and valuable source of nutrients. The advantages of a fully developed variable rate slurry spreader technology cannot be overemphasized.[1] Such systems can give much more accurate results with as-applied verification, while reducing commercial fertilizer inputs and providing… read more »
Introduction Nitrogen (N) is one of the most important mineral nutrients for plant growth, yield and crop quality. Precise timing and rate of N fertilizer application play a major role in plant nutrition. Prediction of N requirements is necessary for efficient utilization of nitrogen fertilizers. Improving the efficiency of N fertilizer utilization reduces the… read more »
Scientific Article Abstract[1] Site-specific application of agricultural chemicals including granular fertilizers is an effective way of resource saving and environmental protection. The objective of this research was to develop and to evaluate the performance of a map-based variable rate row crop granular fertilizer placement system. The applicator system consists of a microcontroller for controlling… read more »

Paper Introduction High-resolution images from digital cameras support the studying of plant characteristics. These images can also be utilized to analyze shape and texture characteristics for weed identification. Instead of detecting weed patches, weed density can be estimated at a sub-patch level, through which even the identification of a single plant is possible. The aim… read more »
Paper Introduction Weed density can be estimated at a sub-patch level, through which even the identification of a single plant is possible. The aim is to adopt the monocot and dicot coverage ratio vision (MoDiCoVi) algorithm in order to estimate dicotyledon leaf cover, perform grid spraying in real time, and present initial results in terms… read more »
