Abstract:
... This study examines the role of farmers' risk attitudes toward fertilizer use in cotton production in China. Contradicting previous studies, this paper theoretically shows that the relationship between farmers' risk aversion and fertilizer use is not always monotonic. Field survey data were collected to test this relationship using the Cobb–Douglas production function. Results suggest that when th ...

Abstract:
... BACKGROUND: Zinc (Zn) deficiency in crops is commonly aggravated by high levels of phosphorus (P) in soil. In this work, the initial performance of pot‐growing maize in response to the available P and Zn in soils with low available Zn and to the application of P and Zn fertilizers was investigated. RESULTS: The soils (six non‐calcareous and 14 calcareous) ranged widely in available P (Olsen P: 5.5 ...

Abstract:
... BACKGROUND: Nitrogen (N) and phosphorus (P) are macronutrients essential for crop growth and productivity. In cultivated fields, N and P levels are rarely sufficient, contributing to the gap between realized and potential production. Fertilizer application increases nutrient availability, but is not available to all farmers, nor are current rates of application sustainable or environmentally desir ...

Abstract:
... Rice paddies are one of the most important anthropogenic sources of ammonia (NH₃) emissions. The seasonal cumulative NH₃–N loss accounts for 9%–60% of the total amount of applied nitrogen (N) fertilizer. Deep placement fertilization (DPF) can effectively improve N fertilizer use efficiency. However, unlike the conventional surface broadcasting fertilization method (CF), DPF technology can only be ...

If a portion of P accumulates in perennial organs in organic fractions it can be used in the next growth season, possibly decreasing plant dependence on P derived from soil fertilization. However, if P is preferentially accumulated in inorgani ...
