Nitrogen-use efficiency of biogas digestate

The digestion of farmyard manure and other organic materials has become increasingly important in recent years. The digestion process produces biogas (methane), and increases the proportion of easily available nitrogen compounds in the digestate produced. To date, there has been little research on the fertiliser value of digested farmyard manure that is of relevance to…

Reducing PPP inputs due to erosion and runoff

Many Swiss streams exhibit high levels of plant-protection product (PPP) inputs, with erosion and runoff being important entry paths. This article furnishes an overview of measures for reducing PPP inputs into bodies of water from arable land due to erosion, runoff and drainage, and provides an expert-based qualitative evaluation of these measures in terms of…

Biodiversity of cow-dung insects and other pasture dwellers not correlated

The biodiversity of agricultural land is usually measured via indicator species that can be recorded time- and cost-efficiently. Behind this approach lies the seldom-questioned assumption that these groups of organisms are good at reflecting the overall species diversity of a habitat. We tested this assumption by comparing the diversity of cow-dung insects with that of…

When must intensive grassland be mown?

The optimum harvest date in spring is a problem that divides producers. Is it better to focus on forage quality with an early cut, or quantity with a later harvest? Trials were carried out on mown grasslands from 2014 to 2016 as part of the «Progrès-herbe» [= «Progress Grass»] and «Preparing Forage Production for Climate…

Vegetable protein as an alternative to meat: an assessment for Switzerland

If self-sufficiency in vegetable protein for the human diet is to be increased, the issue should be considered as comprehensively as possible. This study presents a systemic analysis of the situation in Switzerland, showing which protein-rich crops are most suited to sustainable and organic farming, highlighting their nutritional potential, and indicating the necessary steps for…
