Novel value-added phosphorus-potassium-activator fertilizers improve phosphorus use efficiency and crop yields

Response of Seed and Oil Yields and Phosphorus Agronomic Efficiency of Soybean to Simultaneous Placement of Nitrogen with Phosphorus under Drought Stress

In order to study yield, yield components and agronomic efficiency of phosphorus in soybean affected by simultaneous placement of nitrogen with phosphorus, an experiment was carried out under moisture stress conditions, at Agricultural Research Station of Bu Ali Sina University, Hamedan, Iran in 2017 in a factorial split plot based on randomized complete block design with three replications. Th...

Comparative Analysis between Ecotoxicity of Nitrogen-, Phosphorus-, and Potassium-Based Fertilizers and Their Active Ingredients

This study aimed to analyze the ecotoxicity of nitrogen-, phosphorus-, and potassium-based compounds to organisms of two different trophic levels in order to compare the toxic effect between high-purity substances and these substances as components of fertilizers. Dilutions were made with the fertilizers' potassium chloride, potassium nitrate, superphosphate, urea, and their equivalent reagents...

Managing Phosphorus for Crop Production

Phosphorus is a macronutrient that plays a number of important roles in plants. It is a component of nucleic acids, so it plays a vital role in plant reproduction, of which grain production is an important result. It is also critical in biological energy transfer processes that are vital for life and growth. Adequate phosphorus results in higher grain production, improved crop quality, greater ...

The influence of organic fertilizers application on phosphorus and potassium bioavailability

A prerequisite to use organic fertilizers in a sustainable way is to quantify the amount of phosphorus and potassium available for plants that could be taken up by a crop. The objective of this study was to evaluate direct and subsequent influence of organic fertilizers addition (poultry manure and two types of composts) on the changes of bioavailability of phosphorus and potassium in soil and ...
