Soil scientists have tested various models to predict soil physical, chemical and biological
properties over the last few decades. Determination of soil phosphorus (P) in soils is difficult …

The accurate estimation of available soil phosphorus (ASP) is required for the effective
management of environmental resources and improving agricultural productivity. Direct …

Purpose Although soil total phosphorus (TP) is a primary and essential large element
reflecting the soil fertility in agricultural ecosystems, studies on model development of TP …

Soil phosphorus (P) is a vital but limited element which is usually leached from the soil via
the drainage process. Soil phosphorus as a soluble substance can be delivered through …

The prediction method is to explore application of multivariate data analysis methodologies
to classify and identify important soil nutrients and pH values. The Principal Component …

Predicting soil phosphorus (P) needs and P fertilizer requirements is important for plant
nutrition and reducing environmental risk. The P requirement (PR) can be calculated from …

A study was conducted to determine the relationships between agronomic soil test P and
environmental soil test P in three soils predominately distributing in three typical agricultural …

Overabundance of phosphorus (P) in soils and water is of great concern and has received
much attention in Florida, USA. Therefore, it is essential to analyze and predict the …

The significance of pH value of soil in assessing the soil fertility has been the motivation
behind writing this research paper. As the pH of the soil is strongly dependent on the extent …

The estimation of soil phosphorus is essential for agricultural activity. The laboratory
chemical analysis techniques are expensive and labor-intensive. In the last decade, near …
