Impact of N-fertiliser reduction on agronomic parameters and quality aspects for drinking water production

Impact of N-fertiliser reduction on agronomic parameters and quality aspects for drinking water production Many groundwater bodies in Northwest-Germany suffer from nitrate leaching in regions with high livestock densities. In Belm-Nettetal (Lower Saxony) farmers have...
Long-term nitrogen fertilization can increase the availability of residual phosphorus in arable soil

Long-term nitrogen fertilization can increase the availability of residual phosphorus in arable soil

Long-term nitrogen fertilization can increase the availability of residual phosphorus in arable soil The agriculture in the Czech Republic has been characterized in the past thirty years by a reduction of 37% in basic fertilization with organic fertilizers, basic...
In-situ real-time NIR monitoring of nitrogen in irrigated cotton northern NSW, Australia

In-situ real-time NIR monitoring of nitrogen in irrigated cotton northern NSW, Australia

In-situ real-time NIR monitoring of nitrogen in irrigated cotton northern NSW, Australia Achieving optimum yield in cotton (Gossypium hirsutum L.) requires pre-season soil nitrogen analysis and frequent in-crop monitoring. The current agronomic protocol requires...
Predicting N status in maize with clip sensors: choosing sensor, leaf sampling point, and timing

Predicting N status in maize with clip sensors: choosing sensor, leaf sampling point, and timing

Predicting N status in maize with clip sensors: choosing sensor, leaf sampling point, and timing Adjusted N fertilization is a key factor to increase N fertilizer efficiency and chlorophyll leaf clip sensors can help to improve it. This study tried to identify the...
Sensitivity of hyperspectral bands to N concentration at different growth stages in winter wheat

Sensitivity of hyperspectral bands to N concentration at different growth stages in winter wheat

Sensitivity of hyperspectral bands to N concentration at different growth stages in winter wheat Spectral indices are a precision tool to increase nutrient use efficiency by estimating N crop status. In this study, canopy hyperspectral reflectance (325 -1075 nm) were...
