Abstract:
... The economic potential of oil palm for Ghana and many other developing countries in the tropics is substantial but largely remain unharnessed. Employing both quantitative and qualitative methods including treatment effect models, this study examines the yield difference between adopters and non-adopters of oil palm Best Management Practices (BMPs) among a large number of smallholder farmers and ho ...

Abstract:
... China currently relies on manual labour to fertilise paddy fields, hindering the improvement of fertilisation uniformity, management efficiency, and fertiliser use efficiency. Following a drastic decrease in the availability of agricultural labour, fertilisation operations are facing increasing labour costs and low reliability rates and this is threatening food security. This study developed an au ...

Abstract:
... Optical crop sensors for variable rate nitrogen application (VRNA) are described as an optimal solution to increase yield while minimizing fertilizer costs, although their operation and acquisition costs could be high. In this study, a partial budgeting approach was used to assess the net income of buying and operating a crop sensor for VRNA for optimizing fertilizer application to winter wheat. T ...

Abstract:
... To meet high demand for rice in West Africa, many governments and the regional and international donor community embarked on ambitious rice sector development. The questions are how much rice farmers have increased rice production in West Africa in the past two decades and what factors have contributed to the increase in rice production there. As a case study on lowland rice farming in central Côt ...

Abstract:
... Until recently, potassium (K) did not receive considerable attention, because of the general belief that soils contain ample amount of this element. In addition, very low rates of potash fertilizer application in agriculture led to rapid depletion of K in the rhizosphere soil, in many underdeveloped countries. This results in a variety of negative impacts, including preventing optimum utilization ...

Abstract:
... This study examines the influence of women's decision-making role on chemical fertiliser use in developing and transition economies. We distinguish two types of women family roles, namely formal household head and informal household head, and examine their impacts and differences on chemical fertiliser use by using nationwide data from 75,923 Chinese rural households. The results reveal the follow ...

Abstract:
... The resistant structure and high carbon/nitrogen ratio (C/N) of cellulosic substrate are the barriers during their anaerobic digestion (AD). Solid-state urea pretreatment was developed in this study to pretreat corn straw and adjust C/N ratio simultaneously for the downstream AD of corn straw. Results showed solid-state urea pretreatment was efficient in lignin removal and achieved the highest lig ...

Abstract:
... The management of fertilizers in a context of climate change and the preservation of the environment is strongly related to the regulation and accumulation of 2-acetyl-1-pyrroline (2AP) in fragrant rice. However, the feasibility of such management strategies in terms of enhancing the accumulation of 2AP has not yet been explored in aromatic cultivars. Here, we investigated the impact of the applic ...

Abstract:
... Estimating balanced nutrient requirements of sugarcane (Saccharum L. spp.) in China is crucial to develop the optimum fertilization strategies to increase yields and fertilizer use efficiency. In this study, the datasets involving the main sugarcane growing ecological regions were collected from field experiments from 1995 to 2019. Quantitative evaluation of fertility of tropical soils (QUEFTS) mo ...
fertilizerapplication, etc ; byproducts; food production; food security; phosphogypsum; phosphorus fertilizers; radioactive waste; radioactivity; rock phosphate; Show all 9 Subjects
Abstract:
... Global food supplies currently depend on producing inorganic P fertilisers from a finite reserve of rock phosphate (RP). P fertilisers are themselves significant pollutants but their production from RP also leaves a phosphogypsum (PG) by-product that is sufficiently radioactive that its reuse is restricted. PG is mostly accumulated in open ‘stacks’ that make up a significant proportion of all Tech ...

Abstract:
... Side-deep fertilization could achieve cleaner and light-simplified production of rice by reducing fertilizer use, improving fertilizer utilization, and alleviating labor shortage. However, little is known about the agronomic and environmental benefits of side-deep fertilization technology and the operational scale of farmers targeted by the government for suitable promotion and subsidization of si ...
... Fertilizer overuse causes serious environmental degradation, and it is important to identify the influencing factors of fertilizer use. To feed the largest population worldwide, China has adopted a productivity-led agricultural policy regime and established the largest public agricultural extension system. Given that China is the largest consumer of fertilizers, understanding the role of public ag ...
... Human intake of selenium (Se) mainly occurs through the food chain, and is largely dependent on the bioavailability of soil Se. Sulfur (S) and phosphorus (P) also as essential nutrients for plants, their antagonistic with Se effects on Se bioavailability should be considered. We conducted pot experiments to investigate the interaction effect on the bioavailability of Se in the soil using a sequent ...
