1、Phosphorus fractions of soils under Lotus corniculatus as affected by different phosphorus fertilizers

In a long-term study, Zhang et al. (2004) showed that fertilizer P was rapidly transformed into slightly labile inorganic P and slowly transformed into moderately labile inorganic P; it remained under these two fractions even after 4 years without P fertilization.

2、Growth, nutrient uptake and symbiosis with rhizobia and arbuscular mycorrhizal fungi in Lotus tenuis plants fertilized with different phosphate sources and

As an alternative to P fertilization, many soil microorganisms that play a key role in soil P dynamics can increase P uptake by plants.

3、Phosphorus use efficiency and management in agriculture

More recently it has been shown that when N and P are applied together as in the widely used P fertilizers, mono-ammonium phosphate (MAP) and diammonium phosphate (DAP), which contain ammoniacal N, N and P interact enhancing P uptake and improving nutrient use efficiency for both nutrients.

A controlled greenhouse experiment was conducted to study the fraction, uptake and fixation of phosphorus (P) and potassium (K) in three soils with contrasting characteristics.

5、Engineering phosphorus metabolism in plants to produce a dual fertilization and weed control system

Plants and most microorganisms are unable to metabolize phosphite (PO 3−3), so we developed a dual fertilization and weed control system by generating transgenic plants that can use phosphite...

Efficiency of Celeriac Fertilization with Phosphorus and Potassium Under Conditions of Integrated Plant Production

The goal of this work was to assess the efficiency of celeriac fertilization with phosphorus and potassium under conditions of integrated plant production. The goal was realized by performing a strict experiment. Celeriac (Diamant cultivar) was the test plant.

Phosphorus depletion and pH decrease at the root–soil and hyphae–soil interfaces of VA mycorrhizal white clover fertilized with ammonium

Phosphorus was supplied as Ca (H 2 PO 4) 2 at a rate of 50 mg P kg −1 soil in the root compartment and 150 mg P kg −1 soil in the hyphal and bulk soil compartments. Nitrogen was supplied as (NH 4) 2 SO 4 at the rate of 300 mg N kg −1 soil uniformly to all compartments.

Orthophosphate availability is a key determinant of plant productivity as it is the only chemical form of phosphorus that can be assimilated by plants to meet their nutritional requirements.

Nitrogen, Phosphorus and Potassium Fertilization Interactions on the Photosynthesis of Containerized Citrus Nursery Trees

The objective of this research was to evaluate the nitrogen, phosphorus and potassium (NPK) fertilizer effect on the development of ‘Valencia’ sweet orange nursery trees budded on Rangpur lime rootstocks in a greenhouse using containers.

Phosphorus speciation and transformation in long

Phosphorus speciation of the soil in three long-term fertilization experiments established in 1990 was investigated jointly with a sequential fractionation scheme and P K -edge X-ray absorption near edge structure (XANES) spectroscopy.

Fertilizing lotus with phosphorus and potassium is a critical practice for promoting healthy growth and flowering. These nutrients provide essential nourishment, enhance water absorption, photosynthesis, and disease resistance. Below is a detailed guide on proper application:

I. Understanding Lotus’s Nutritional Needs

1. Physiological Characteristics of the Plant:

   • As an aquatic plant, lotus requires nutrient-rich soil and良好的排水条件 (good drainage conditions).
   • During the growing season, it demands significant amounts of nitrogen (N), phosphorus (P), and potassium (K) to support rapid growth.
   • In the flowering stage, phosphorus and potassium become尤为重要 (especially crucial) for bud differentiation and blooming.

2. Fertilizer Selection:

   • Use specialized compound fertilizers or organic fertilizers formulated for aquatic plants, which typically contain balanced N-P-K and microelements.
   • Avoid fertilizers containing heavy metals or harmful chemicals to prevent water pollution.

II. Timing and Methods of Fertilization

1. Timing:

   • Spring: Key period for promoting new leaf growth and flower formation.
   • Hot Summer: Reduce dosage to avoid root burn from high temperatures.
   • Autumn: Cease fertilization as the plant enters dormancy to prepare for winter.

2. Methods:

   • Surface Application: Evenly spread fertilizer around the root zone, avoiding direct contact with roots.
   • Deep Placement: Bury fertilizer in soil at a safe depth below the water surface to prevent loss via water flow.
   • Regular Application: Adjust frequency and dosage based on growth stages and soil tests.

III. Precautions

1. Avoid Over-Fertilization:

   • Excessive phosphorus and potassium can lead to algal blooms and water quality issues.
   • Symptoms of over-fertilization include yellowing leaves and stunted growth.

2. Balanced Nutrition:

   • Complement phosphorus-potassium fertilizers with适量氮肥 (moderate nitrogen) to meet full growth cycle needs.
   • Ensure proper ratios to prevent antagonistic effects between nutrients.

3. Eco-Friendly Practices:

   • Prioritize organic fertilizers to minimize chemical pollution.
   • Maintain clean water during application to protect aquatic ecosystems.

Phosphorus and potassium fertilization are vital for lotus health and blooming. By selecting appropriate fertilizers, timing applications correctly, and adhering to precautions, you can optimize results. Emphasizing environmental sustainability and scientific management ensures long-term success.
