“…Consequentially, high productive systems are producing at the yield maximum and low productive systems as environmental friendly as possible. That could also mean to shift certain cultivars to better fitted areas making agricultural environments more specialized (e.g., [78,83]). One publication estimated the influence of nanotechnologies on the fertilizer use and production [84].…”

“…Furthermore, it can provide a good information exchange, which is also an important trigger for the adoption of disruptive process innovations [67,78,83,97,99,101,102]. To push a new production technology, farmers need to have access to a market where they can buy the technology or the knowledge about this specific technology and where they can get a credit for this particular purchase.…”

“…Higher education levels can have a stimulation effect because they can provide the farmer with a higher willingness for live long learning and cooperation. A bigger farm size can give farmers a better foundation for finical investments and can therefore trigger the eco-innovation adoption [67,76,78,83,[98][99][100][106][107][108]. If the land is additionally owned by the farmers themselves, the willingness to invest in new technologies to maintain soil fertility and soil quality is much higher [97,99,[104][105][106].…”

Drivers for the Adoption of Different Eco-Innovation Types in the Fertilizer Sector: A Review

Numerous innovations have been developed in the fertilizer and plant nutrition area in recent decades. However, the adoption of many new products and techniques at farm level is still low. In this paper, based on a literature review, we explore the main drivers for innovation adoption or rejection. By splitting up the extant research landscape into disruptive and continuous innovations and innovation types (product, process and innovation of other types), we aim to identify drivers explaining innovation adoption in the fertilizer sector in particular and in the agricultural sector in general.

“…However, a large number of empirical studies have shown that the excessive fertilizer use has been a source of agricultural non-point source pollution in addition to causing numerous environmental and ecological problems which include greenhouse gas emissions, water pollution, changes of soil properties, declining productivity, deterioration of agricultural production quality, as well as loss of biodiversity and ecosystem services [11][12][13][14][15][16][17][18]. Now, research studies have paid more attention to the spatial and temporal variations of fertilizer use across the world.…”

“…Actually, the efficient use rate of fertilizer in China is still no more than 50%. It is a common phenomenon that fertilizer is overused and misused in China's grain production [15,27]. This circumstance has caused many problems such as increasing agricultural production costs and environmental pollution.…”

Abstract:In order to fully explore the fertilizer use intensity and its potential threats to the ecological environment, this paper has studied the decomposition of fertilizer use intensity and its environmental risk in China's grain production. Based on the statistical data collected from 10 provinces during 2004-2015 in China's grain producing areas, this paper has analyzed the effect of fertilizer use intensity from a regional perspective. The environmental risk assessment model considers some factors such as the fertilizer application safety thresholds use efficiency, multiple cropping index, and environmental impact weight. The fertilizer application safety thresholds are calculated on the target output of local food crops. The results show that: (1) during 2004-2015, the fertilizer use intensity shows an increasing trend in China's grain producing areas, and the intensity is significantly higher than the upper limit of the international safety fertilization; (2) the cumulative contribution rate of the increase of fertilizer use intensity caused by regional fertilizer use efficiency and grain planting structure adjustment are 57.03% and 1.81% respectively; (3) in 2015, China's grain producing areas' environmental risk index of phosphorus and potash was low, with the values in these two provinces being quite different and indicating the characteristics of aggregation and distribution. Therefore, the Chinese government should unswervingly encourage the application of some technology that could save fertilizer and increase efficiency, establish environmental risk monitoring and control systems, and improve relevant policies and regulations.

The rapid expansion of commercial‐scale cellulosic industries raises the prospect of widespread crop residue harvest. However, the effects of integrated crop residue and tillage management strategies on agricultural sustainability are not fully understood. Here, we investigated the effects of different integrated crop residue and tillage management strategies on crop productivity, economic profit, soil quality, and agricultural sustainability in an intensive wheat (Triticum aestivum L.)–maize (Zea mays L.) double‐cropping system over 7 yr. The treatments included residue return of both crops (WrMr), wheat residue return with harvesting maize residue (WrMh), wheat residue return with stubble at a height of 30∼40 cm and harvesting maize residue (WsMh), maize residue return with harvesting wheat residue (WhMr), maize residue return with subsoiling and harvesting wheat residue (WhMs), and residue harvest of both crops (WhMh). The annual average grain yields of wheat and maize increased by 17.6∼36.1% and 9.9∼22.8% under integrated strategies relative to those in WhMh. Compared with the WhMh, the WsMh and WhMs increased the economic profit (EP) by 9.5 and 6.1%, respectively. The integrated strategies significantly improved the chemical, biological, and physical properties of soil, resulting in higher sustainability indices (SIs) relative to the WhMh. The SIs were 1.59 and 1.33 in WrMr and WhMs, respectively, higher than the lowest value when a sustained system needed. Therefore, the adoption of maize residue return with subsoiling and harvesting wheat residue can maintain agricultural sustainability in the wheat–maize double cropping system under commercial‐scale cellulosic industries’ expansion in the north‐central plain of China.
