Phosphorus Fertilization of Sugarbeets [PDF]

Journal of Sugarbeet Research, 1977
Sugarbeets (Beta vulgaris L.) have been fertilized with phosphorus (P) in the U.S.A. for the past 30 to 40 years. During this period, numerous studies on P fertilization rates and application methods have been conducted. Much of this information has been summarized (12, 14, 15, 4). Recent soil test data from England and the U.S.A.

Phosphorus fertilization of ‘Fuyutoyo’ cabbages in phosphorus-rich Eutrustox soil [PDF]

Chilean journal of agricultural research, 2013
Crop fertilization with P is a practice that constantly needs to be improved because of its high cost, natural reserve constraints, and environmental impact caused by the excessive use of nutrients. Phosphorus rates (0, 120, 240, 360, 480, 600, and 720 kg P2O5 ha-1) in the cultivation of 'Fuyutoyo' cabbage ( Brassica oleracea L. var. capitata) in a P-

Soil test phosphorus and cumulative phosphorus budgets in fertilized grassland [PDF]

AMBIO, 2015
We analyzed the linearity of relationships between soil test P (STP) and cumulative phosphorus (P) budget using data from six long-term fertilized grassland sites in four countries: France (Ercé and Gramond), Switzerland (Les Verrières), Canada (Lévis), and Finland (Maaninka and Siikajoki).

Retracted: Can the chemical industry solve the climate change?On the role of human energy production, renewable energies, and the potential of chemistry as a solution provider

Chemie Ingenieur Technik, EarlyView., 2023
Let us consider an alternative perspective on climate change: The sum of solar radiation and heat generated by human activity result in a net energy input of 1.96 times that of the Sun on the Earth's surface. The expanding global population is expected to exacerbate this issue. Potential solutions are proposed, including replacement and heat recycling.

Arbuscular Mycorrhizas and Phosphorus Fertilizer Affect Photosynthetic Capacity and Antioxidant Enzyme Activity in Peppermint Under Different Water Conditions

Acta Agrobotanica, 2021
In order to investigate the effect of arbuscular mycorrhizas and phosphorus levels on photosynthetic capacity and enzyme activity in peppermint under different water conditions, an experiment was conducted during the 2017–2018 growing seasons.

Balancing the Global Distribution of Phosphorus With a View Toward Sustainability and Equity [PDF]

, 2018
Limitations in the geological reserves of phosphate rock, the source of fertilizer phosphorus, are not currently considered in agricultural practices or global trade, a very short‐sighted approach considering that there is no “alternative fuel” for plant

Trade-Off Strategy for Usage of Phosphorus Fertilizer in Calcareous Soil-Grown Winter Wheat: Yield, Phosphorus Use Efficiency, and Zinc Nutrition Response

Agriculture
Although phosphorus (P) fertilizer application is widely used to improve production, irrational P application has a negative impact on the zinc (Zn) nutrition of cereal crops. Previous researchers observed and confirmed that P application decreases grain

Response of Soil Microbial Community Structure to Phosphate Fertilizer Reduction and Combinations of Microbial Fertilizer

Frontiers in Environmental Science, 2022
The excessive application of phosphorus (P) fertilizer is becoming a major agricultural problem, which reduces the utilization rate of the P fertilizer and degrades soil quality.

Matching Phosphorus Fertilizer Types with Soil Type in Rice Cultivation Optimizes Yield, Soil Phosphorus Availability, and Phosphorus Fertilizer Use Efficiency

Agriculture
Inefficient phosphorus (P) fertilizer application often accumulates soil P, wasting valuable phosphate resources and contributing to environmental pollution.
