Biochar has been frequently suggested as an amendment to improve soil quality and mitigate climate change. To investigate the optimal management of nitrogen (N) fertilization, we examined combined effect biochar N fertilizer on plant uptake N2O emissions in a cereal rotation system randomized two-factorial field experiment sandy loam Brandenburg, Germany. The treatment received 10Mgha-1 wood-derived September 2012. Four levels fertilizer, corresponding 0, 50%, 100%, 130% recommended level,...
Abstract Autonomous equipment for crop production is on the verge of technical and economic feasibility, but government regulation may slow its adoption. Key regulatory issues include requirements on‐site human supervision, liability autonomous machine error, intellectual property in robotic learning. As an example impact benefits equipment, analysis from United Kingdom suggests that requiring 100% supervision almost wipes out small medium farms increases economies‐of‐scale advantage larger farms.
The objective of our research was to identify economically efficient corn ( Zea mays L.) based tillage‐rotation combinations using a 20‐yr data set from long‐term experiment in Ontario, Canada. Seven rotations two tillage systems (moldboard and chisel plow) were analyzed. We found multiple benefits associated with diversifying both integration soybean [ Glycine max (L.) Merr.] or wheat Triticum aestivum resulted 7 11% higher yields the system. In plow system yield rotation increased by 5%,...
During the past years, most biochar studies were carried out on tropical soils whereas perennial field experiments temperate are rare. This study presents a 3-year experiment regarding effects of differently produced biochars (pyrolyzed wood, pyrolyzed maize silage, hydrothermal carbonized silage) in interaction with digestate incorporation and mineral N fertilizer application soil C N, crop yields winter wheat, rye quality wheat. Soil plant available potassium found to be significantly...
Abstract To better understand the complex interactions between irrigation and nitrogen fertilizer application on soil organic carbon content, results from long‐term field experiments over a period of 40 years were analysed. The combined effect rates crop yields, input by above ground harvest residues content has been investigated at site sandy in northeast Germany. Combined with application, frequently had significantly positive yield inputs residues. However, enhanced to under did not lead...
Feed and food production are inter alia reasons for high greenhouse gas emissions. Greenhouse emissions could be reduced by the replacement of animal components with plant in processed products, such as pasta. The main currently used pasta semolina, water, well additional egg. hypothesis this paper is that substitution whole egg plant-based ingredients, example from peas, a product might lead to (GHG) thus carbon footprint at economically reasonable costs. costs footprints two types,...
This paper analyses the comparative advantage of using silage maize or grass as feedstock for anaerobic digestion to biogas from a greenhouse gas (GHG) mitigation point view, taking into account site-specific yield potentials, management options, and land-use change effects. GHG emissions due production were calculated life-cycle assessment approach three different site conditions with specific potentials adjusted options. While use maize, per energy unit same varied substantially grassland...
The use of nitrogen (N) fertilizer substantially contributes to greenhouse gas (GHG) emissions due N2O from agricultural soils and energy-intensive manufacturing. Thus, a reduction mineral N can contribute reduced GHG emissions. Fertilizer tax is potential instrument provide incentives apply less the mitigation This study provides model results based on production function analysis field experiments in Brandenburg Schleswig-Holstein, with respect risk aversion by calculating certainty...
Reduced tillage results in lower production costs and thus may have economic advantages for farmers. However, yield penalties, specific risks, or higher nutrient requirements counteract the positive effects of reduced tillage. This study investigates long‐term (moldboard plow, deep shallow chisel plow) their interactions with N fertilizer input on yields performance a corn ( Zea mays L.)‐wheat Triticum aestivum L.)‐potato Solanum tuberosum rotation southern Germany. Conventional (CT) systems...
The potential role of irrigation cereals as a response to climate change is under debate. Especially temperate continental conditions empirical evidence crop yield in interaction with nitrogen fertilizer supply rare. Besides mean effects, reduces variance, which may be an incentive for farmers use irrigation. This paper investigates the risk-efficiency cereal production climate, based on data from long term field experiment sandy soil. Irrigation and no winter rye (Secale cereale) barley...
