The objective is to develop remote sensing methods to estimate forage nutrition and yield in the field in Northern Sweden. Field and lab measurements on grass-legume mixtures will be conducted from June 2018 to December 2019. At sampling time, drones flight with multispectral cameras, hyper-spectral reflectance measurement (e.g. with Yara N-sensor), and an ultrasonic sensor, will be conducted in order to build prediction models for forage nutrition and yield. The project will develop models for estimating forage digestibility based on a small number (e.g. red, red-edge and NIR) of wavelengths, thus enabling the use of lighter and cheaper technologies that could be mounted on a drone or even on a smart phone. After models are developed at point scale, data from the drone flights can be used to produce a field map of real-time crop growth and nutritional status. Models developed with the Yara N-sensor can be directly used with a commercialized tractor-mounted sensor.
Regional jordbruksforskning för norra Sverige (RJN) ansöker om medfinansiering till bifogat projekt, som beviljats delfinansiering av styrgruppen. Målet är att utveckla fjärranalysmetoder för att uppskatta näringsvärde och avkastning i fält i norra Sverige. Prover tas under 2018-219 från blandvallar och analyseras på näringsvärde. Samtidigt genomförs mätningar med fjärranalysmetoder för att bygga prognosmodeller för näringsvärde och avkastning. Metoderna inkluderar drönare med multispektrala kameror, mätning av hyperspektral reflektion (med Yara N-sensor) och en ultraljudssensor. Projektet kommer att utveckla modeller för att uppskatta fodrets smältbarhet, vilket möjliggör användande av billig teknik som kan monteras på drönare el. dyl. Efter att modeller har utvecklats kan data från drönarflygningarna användas för att producera en fältkarta över realtidstillväxt och näringsstatus. Modeller som utvecklats med Yara N-sensorn kan även användas med en kommersiell traktormonterad sensor.

The purpose of this project is to define the amount of slaked lime needed for a given clay soil. We hypothesise that the amount of slaked lime needed for minimal phophorus loss is dependent on the clay content of the soil. The study will be conducted in a field with a drainage system and measuring …

Increased production and export of products with high added values, e.g. long-ripened hard cheeses, are considered important steps for a positive development of the Swedish dairy sector. Increased investment in Swedish premium cheese will, however, require increased volumes of high quality raw milk …

Wheat bran is the largest by-product of wheat flour production with approximately 300,000 tonnes in Sweden. Bran is mainly used in animal feed, as human digestion is not fully able to absorb it. Wheat bran contains valuable biomolecules, such as dietary fiber (arabinoxylans, AX) and phenolic …

We are facing a protein shift in which a portion of the animal based protein in our diet needs to be replaced by plant proteins to reduce the climate impact from the food sector. Many agricultural by-streams contain high value proteins not used to their full potential. We aim to recover proteins …

Using split fertilization of nitrogen (N) in wheat production is today well-established to increase protein content and adjust fertilization. However, deep knowledge and understanding of N uptake and remobilization during late stages of crop development are missing. Moreover, while split …
