The Hedley sequential‐phosphorus (P)‐fractionation method has been used in many
countries to study the effects of land‐use and management systems on soil P. Many data …

Deforestation and land-use change in tropics have increased over the past decades, driven
by the demand for agricultural products. Although phosphorus (P) is one of the main limiting …

Large inputs of phosphorus (P) in chemical fertilizers and feed supplements since 1978
have improved soil P status in arable land in China, but have also created challenges by …

This paper reviews recent advances on studies on the role of organic phosphorus in tropical
agroecosystems, with emphasis on the effects of management on soil organic phosphorus …

Abstract Evaluating Best Management Practices (BMPs) in watersheds using hydrologic and
water quality models can help to establish an effective watershed water management. Soil …

A 4-year field trial with three treatments and three types of annually rotated vegetables was
conducted in calcareous soil in a greenhouse using a phosphorus (P) fractionation method …

Phosphorus deficiency is wide-spread due to the poor solubility of soil P and the rapid
formation of poorly available P after P addition. Microbes play a key role in soil P dynamics …

A field experiment was conducted on an Andosol to evaluate wheat (Triticum aestivum L.)
yield, P and N uptake and soil P fraction after long-term fertilization (no fertilizer, NPK, NP …

The availability of P from injected manure application has received limited study. The
objectives of this study were to determine the effect of time on P availability in soils amended …

Land use and land cover (LULC) change is critical to hydrologic study as it affects surface
runoff, sediment yield, and nutrient load from watersheds. Change in LULC is a continuous …
