Many farming-system studies have investigated the design and evaluation of crop-management practices with respect to economic performance and reduction in environmental impacts. In contrast, little research has been devoted to analysing these practices in terms of matching the recurrent context-dependent demand for resources (labour in particular) with those available on the farm. This paper pr...

The role acquired by modelling in plant sciences includes integration of knowledge, exploration of the behaviour of the plant system beyond the range of conditions covered experimentally and decision support. The purpose of the model determines its structure. Initially process-based models (PBM) were developed separately from structural (or: architectural or morphological) plant models (SPM). C...

In the frame of operational remote sensing based National Crop Monitoring and Production Forecast Program (CROPMON) the Remote Sensing Center of Institute of Geodesy, Cartography and Remote Sensing, (FÖMI RSC) provided nation-wide crop production forecasts. The technology of CROPMON served as the background of disaster monitoring. The achieved results of ESA–FÖMI Prodex-ENVISAT R&D project demo...

To study crop recommendation fertilization of the rural farmers as the main in our country, the paper took towns and villages of Hua County as the study area, took recommendation fertilization of wheat, maize and peanut as the study object, designed model components of crop balance fertilization by using Object-Oriented technique, and developed the decision-making system about crop recommendati...

The practice of adding organic amendments to crop soils is undergoing resurgence as an efficient way to restore soil organic matter content and to improve soil quality. The quantity and quality of the organic matter inputs affect soil physicochemical properties and soil microbiota, influencing different parameters such as microbial biomass and diversity, community structure and microbial activi...

Phosphorus is a macronutrient that plays a number of important roles in plants. It is a component of nucleic acids, so it plays a vital role in plant reproduction, of which grain production is an important result. It is also critical in biological energy transfer processes that are vital for life and growth. Adequate phosphorus results in higher grain production, improved crop quality, greater ...

The ISU Crop Bioengineering Consortium (CBC) was organized to address the urgent, grand challenge to provide sufficient food, feed, biofuels and biorenewable chemicals for the world’s burgeoning population, through basic and applied research, to enable the bioengineering of valuable traits in a variety of crops. Importantly, the novel technologies employed can produce bioengineered crops that c...

Relevance Concerns about the environmental impact of farming has increasingly been the focus of discussions in the EU. Croplands, a primary land use in Europe, have a significant impact on the environment (soil, water bodies, global climate, local biodiversity and human health). The use of fertilisers and pesticides associated with conventional farming may lead to pollution and/or climate chang...

Agricultural production system is an outcome of a complex interaction of seed, soil, water and agro-chemicals (including fertilizers). Therefore, judicious management of all the inputs is essential for the sustainability of such a complex system. The focus on enhancing the productivity during the Green Revolution coupled with total disregard of proper management of inputs and without considerin...
