In the previous article [Ammann, K. (2008) Feature: integrated farming: why organic farmers should use transgenic crops. New Biotechnol. 25, 101-107], in a plea for the introduction of transgenic crops into organic and integrated farming, it was announced that the complementary topic, namely that high tech farmers should integrate elements of organic agriculture, will be a follow up. Some selec...
Die als Ergebnis der konzeptuellen Datenmodellierung im Rahmen des Precision Dairy Farming vorliegenden getrennten Modelle für operative und analytische Daten sind in ein logisches Modell zu überführen. Wir propagieren dabei den Entwurf eines gemeinsamen relationalen Modells für beide Datensichten. Nur so kann Redundanz und Inkonsistenz auf Modellund Datenebene vermieden werden. Anhand eines Be...
In recent years, the productivity of cotton in Brazil has been progressively decreasing, often the result of the reniform nematode Rotylenchulus reniformis. This species can reduce crop productivity by up to 40%. Nematodes can be controlled by nematicides but, because of expense and toxicity, application of nematicides to large crop areas may be undesirable. In this work, a methodology using ge...
Many studies on the adoption of precision technologies have generally used logit models to explain the adoption behavior of individuals. This study investigates factors affecting the intensity of precision agriculture technologies adopted by cotton farmers. Particular attention is given to the role of spatial yield variability on the number of precision farming technologies adopted, using a cou...
This paper innovates as it tests two different hypotheses regarding climate impacts on agricultural markets in Brazil: farmers only observe the average climate conditions of their region when deciding the type and amount of crop/animal to grow/raise; and weather diversions from normal climate conditions deviate farmers from their optimal profits. Both hypotheses are not rejected by the data. Th...
Introduction Precision livestock farming (PLF) technology development has proliferated recently, but on-farm adoption lagged. Understanding PLF stakeholders’ views, practical applications, limitations, and concerns are necessary to understand the factors influencing of technology. Methods Using semi-structured online interviews, 12 influential views lived experiences were investigated. A phenom...
